G300006 Installation Manual

Installation Requirements

Read pages 2 ­ 10 of this manual prior to installation or operation of the G30.

The information in this section is very important for proper operation of the compressor. Read these requirements prior to beginning the installation.
When determining a mounting location for the G30, ensure the following conditions are met (Figure 1):
· The fuel shut off valve is easily accessible (the fuel valve must be shut off
when the unit is not in use, including during transport).
· The sight glass, oil drain and filters on the WHASP Tank are easily accessible
for service.
· The belt guard is accessible and can be removed for service. · The engine oil drain, oil fill, fuel fill, and air filter are easily accessible for
service (the VMAC Remote Oil Drain accessory can help facilitate servicing the engine and compressor oil P/N: A500043).
· There is adequate access to cool fresh air for optimum engine performance. · There is sufficient clearance around the unit for good air circulation and
effective cooling.
· The unit is mounted in a position where hot air and exhaust will not recirculate
back into the system.
· The unit is protected from damage and excessive exposure to the elements. · The unit is away from heat sources such as engines, exhaust systems or other
components that generate heat.
· The unit is not in a location where it will be exposed to high contamination
levels, including combustible gases.
· The exhaust is routed to open air and not orientated in a way that will fill with
rain.

Ventilation Requirements
Adequate ventilation is vital for safety as well as proper operation of the engine. Systems without adequate cooling may experience stalling, premature oil deterioration, increased oil consumption, power loss, and reduced life or failure of the engine and/or compressor.
If the compressor overheats, the temperature switch will shut down and disable the engine until the oil temperature drops below 140 °C (284 °F).
During operation, the G30 generates a considerable amount of heat that must be evacuated away from the unit for it to run efficiently. The engine is air cooled and requires an adequate supply of cool fresh air to cool the engine and allow proper fuel combustion. Ensure there is a minimum of 6 in of clearance between the engine air intake (the recoil starter area) and any other components mounted on the vehicle. The WHASP cooler fan should have a minimum of 12 in of clearance in front of it, however unobstructed venting to open atmosphere is preferred. The engine exhaust must be vented away from the G30 and toward a safe location (the exhaust tip can be rotated to change the exhaust direction if needed). If mounted in an enclosure (such as the bed of a pickup truck box), the exhaust must be vented outside of the vehicle to prevent the gas engine from ingesting its exhaust and overheating or stalling (Figure 2).
Exhaust and waste heat from the G30 system must be vented away from the system to prevent the gas engine from ingesting its exhaust and stalling.

Mounting Locations

VMAC does not recommend mounting the unit at the back of the vehicle as the drag created when the vehicle is moving causes debris to be deposited (and accumulated) inside the unit.

Ensure the engine exhaust and hot air generated by the gas engine and WHASP Tank cooler are routed in such a way as to prevent recirculation back into the unit.
Note that the fan on the WHASP Tank is a “puller” fan.

Ensure the fuel shut off valve is easily accessible. The fuel valve must be shut off when the unit is not in use, including during transport.
Maintain a minimum of 6 in between the sides of the G30 and 1 ft in front of the WHASP cooling fan and all other solid objects (Figure 3 on page 16).
Top Mounting
When selecting a top mount location, consideration must be taken regarding environment conditions. Precautions should be taken to limit the exposure of rain, snow, dust and debris directed towards the engine, compressor and generator air intakes, both while the vehicle is in motion, as well as when the vehicle is parked (This includes when the G30 is in use).
Consider the following:
· Inclement weather such as rain and snow. · Dust and debris directed at the G30.

Enclosed Mounting

Enclosed mounting must incorporate one of the following to ensure an adequate supply of cool fresh air to the engine, and to remove all of the engine exhaust and heat generated from the system:
· The unit must be mounted on a pull out tray that is extended anytime the unit is run. In general, this is the simplest method.
· The cabinet must be designed with features such as ducting and intake/exhaust fans.
Mounting the G30 in an enclosure will limit access to cool fresh air, restrict the escape of hot air from around the unit and have an adverse effect on cooling, engine performance and reduce the unit’s duty cycle. Ensure adequate ventilation is provided for cooling and to evacuate the exhaust. If mounting in an enclosure, VMAC strongly recommends mounting the unit on a pullout drawer and extending the drawer any time the unit is run.
While it is not possible to make absolute recommendations regarding ventilation due to the widely differing circumstances that are possible, duty cycle, ambient temperature and enclosure shape are some of the important variables that must be considered.

Electrical Connections
Failure to sufficiently ground the G30 could cause severe injury or death due to electrical shock and static discharge.
While the American Welding Society® Safety & Health Fact Sheet No. 29 (Grounding of Portable and Vehicle Mounted Welding Generators) is a great reference for grounding the G30, VMAC recommends working/consulting with a certified electrician and local regulatory bodies when grounding the G30.
Certified electricians and local regulatory bodies can assist with any questions or concerns regarding proper grounding, and compliance with local regulations.
The G30 must be grounded to the vehicle frame (or an earth ground when not mounted to a vehicle) to prevent electrical hazards.
The vehicle mounted ground connection must be made by bare metal to metal contact to the vehicle frame as some service body materials (e.g. plastics, wood, bedliners, etc.) may insulate the G30 from the frame, resulting in inadequate grounding.

Main System Ground (Vehicle Mounted)
Connect a ground wire with a minimum size of 10 AWG to the ground terminal located on the engine side of the unit, next to the air outlet (Figure 6).

Ground post

Identifying Your System
The System ID will be requested any time that parts are ordered, when calling for technical support or submitting a warranty claim. The system ID is the preferred method of identifying the system as it serves as a master record of all of the components in the system. The system ID plate is generally found on the belt guard of the Gas Driven Air Compressor (Figure 9).

Figure 9 — System ID location
An alternative method of identifying the system is via the compressor serial number which is found on a plate attached to the compressor. This is a less desirable method of identifying the system as it may not link back to the original system if it has been replaced.
System ID breakdown
The system ID provides specific information about the system such as the model, revision, production date and the unique identifier (Figure 10).

Operating Principles

Air Compression
The G30 uses a VMAC designed and manufactured flooded lobe, rotary screw compressor. The oil filled compressor housing contains 2 rotors. Compression occurs when air (at normal atmospheric pressure) enters a chamber where it is trapped between meshing rotor lobes. Cooled oil is injected into the rotors during compression to lubricate the rotors and bearings, absorb the heat of compression, and seal the rotor lobes to allow for efficient compression. As the rotors rotate, the meshing lobes compress the volume of the trapped air/oil mixture before sending it down the discharge line to be cooled and separated by the Waste Heat Air Separation Package (WHASP) Tank.

Oil Separation and Cooling
The WHASP Tank is a 2 stage air/oil separator and oil cooler. The hot air/oil mixture from the compressor enters the cooler at the top of the WHASP Tank where the mixture is cooled and the majority of the oil separates from the air and settles into the reservoir tank below the cooler (first stage separation). The cooled oil then passes through a high pressure oil filter before being returned to the compressor via the oil return line. The air stream then passes through a coalescing filter where the remaining oil is removed (second stage separation). The oil collected by the coalescing filter is returned to the compressor via the 1/4 in PTFE scavenge tube.
A liquid to air cooler with electric fan maintains the operating temperature which reduces the temperature of the compressed air and increases the system’s durability.

Minimum Pressure Check Valve
The WHASP Tank has a built-in minimum pressure check valve (MPCV) to maintain a minimum pressure of approximately 60 psi (414 kPa) in the WHASP Tank, this ensures there is adequate compressor lubrication, cooling, and oil separation in the coalescing filter. Air will not flow out of the WHASP Tank until approximately 60 psi is reached. The MPCV is factory set and requires no adjustment or servicing.
The VMAC WHASP Tank has a built-in check valve. Use of an additional check valve is not required and may cause erratic performance.
Pressure Regulation
Pressure regulation is achieved with a combination of an inlet valve regulator, a mechanical unloader valve and a discharge valve. Use a Filter Regulator Lubricator (FRL) to regulate downstream pressure to the tools.

VMAC Technical Support: 888-241-2289

Filtration
VMAC rotary screw compressors are designed and machined to exacting tolerances. Foreign particles entering the compressor can damage system components such as seals, bearings, rotors, as well as the inside of the housing, resulting in performance losses and reduced system life.
The system is equipped with a replaceable paper element inlet air filter, spin on high pressure oil filter and a spin on coalescing filter.
These system filters enhance performance and extend component life by reducing damage from dust and other debris. Proper maintenance is required to maintain system performance and extend the system’s life.
Compressor and Generator Drive, Belt and Tensioning
The compressor and generator are directly driven by a 4 rib belt. Anytime the engine is running the compressor and generator are running. The system has two automatic belt tensioners, manual adjustment is not required.

System Pressure Unload
Internal system pressure is controlled via a mechanical unloader valve. When downstream air pressure reaches 135 psi (air pressure to the air tools), the mechanical unloader valve activates and sends a signal to the mechanical discharge valve to open. When open, the mechanical discharge valve sends internal system pressure (pressure inside the compressor and WHASP Tank) to the inlet valve and closes the compressor air intake poppet. Internal air pressure is then vented to a nominal value which reduces the load on the engine. This allows the control system to reduce engine speed which improves fuel efficiency, as well as reducing emissions and wear and tear on the system. When downstream pressure drops below 110 psi, the unloader valve will close and “load” the system, allowing it to build air.

The G30 uses a 5.2 kWh 60 Hz @3,600 rpm single phase 2 pole generator with Automatic Voltage Regulator (AVR).

Spark Arrester
The gas engine is supplied with a spark arrester.
For more information regarding the spark arrester, refer to the Honda GX390 Owner’s Manual supplied with the system (VMAC P/N: 1901066).

Extreme Climates and Elevation

The G30 has been designed to operate in moderate climates of 0 °C to 40 °C (32 °F to 104 °F)below 3,500 feet. Operating outside of this range may result in performance issues with the engine, compressor, and generator.
Cold Environment Operation
The G30 system is not designed or recommended for use in cold climates (below 0 °C / 32 °F) unless equipped with a VMAC cold climate kit (P/N: A500044).
If equipped with the optional VMAC Cold Climate Kit (P/N: A500044), the cold climate kit must be turned off prior to starting the engine, and must remain off for the duration of engine operation.
Prior to operating the G30, clear any accumulated snow or ice from the:
· Engine air intake, exhaust, and recoil starter area.
· WHASP Tank cooler and fan.
· Generator air intake and air exhaust.

Cold Environment Recommendations
· Ensure the following conditions are met before starting the system: · Use the choke in cold environments, or for first start of the engine. · The system’s components must all be at, or above 0 °C (32 °F). Starting the
system while any of the components are below 0 °C (32 °F) may result in excessive engine cranking while starting, the engine failing to start, belt slippage, and engine stalling. Use the optional A500044 Cold Climate Kit or store the system indoors and start it while the components are still warm.
· For engine oil recommendations in temperatures below 0 °C (32 °F), refer to
the Honda Owner’s Manual supplied with the system (P/N: 1901066). Failure to follow the recommendations in the Honda Owner’s Manual may result in poor engine performance or engine damage.

The unloader valve should be manually activated to aid start up; this will
reduce the load on the compressor, resulting in less load on the engine during warm up (Figure 11 on page 30).
While the unloader valve is manually opened, the compressor will only produce approximately 40 psi. Once the engine has reached normal operating temperature, close the unloader valve to allow the system to build to full system pressure.
The optional A500044 Cold Climate Kit is a starting aid only. Contact a Honda dealer for recommendations when operating the engine below -15 °C (5 °F).

Hot Environment Operation
Operating the G30 fully loaded for extended periods in temperatures above 40 °C (104 °F) may result in the system shutting down due to the compressor oil overheating. Placing high demand on the engine (e.g. continuous demand at 135 psi) for extended periods can also result in higher than normal engine oil temperatures. To avoid overheating the engine or compressor, VMAC recommends installing an air receiver tank. This will help to reduce the duty cycle of the compressor by allowing it to unload.

The compressor system is protected by a compressor oil temperature switch that opens at 140 °C (284 °F) and shuts down and disables the engine until the compressor oil temperature drops below 139 °C (282 °F). The cooling fan will continue to operate at anytime as it is powered directly from the battery.
If the G30 shuts off due to overheat, allow the system to cool sufficiently before restarting.
For engine oil recommendations in temperatures above 40 °C (104 °F) refer to the Honda GX390 Owner’s Manual supplied with the system (VMAC P/N: 1901066). Failure to follow the information supplied in the Honda Owner’s Manual may result in poor engine performance or engine damage.

Hot Environment Recommendations
A receiver tank can help prevent overheating issues by lowering the duty cycle of the compressor.
· Ensure there is an adequate supply of cool ambient air to the unit. · Ensure the exhaust and hot air are able to vent from the system with no
restrictions.
· Ensure the WHASP radiator fins, engine recoil starter, generator air intake and
air exhaust areas are clear of debris.
· Install an external fan to direct cool air toward the engine and air compressor. · Ensure the engine, compressor, and generator are serviced at correct intervals.

High Altitude operation
The G30 has been designed to operate from 0 to 3,500 feet above sea level.
Operation above 3,500 feet may limit the compressor performance and may cause the engine to stall. For operation between 3,500 and 5,000 feet, lowering the compressor duty cycle is recommended.
For more information regarding high altitude operation refer to the Honda GX390 Owner’s Manual supplied with the system. Failure to follow the Honda Owner’s Manual may result in poor engine performance or engine damage.

Before Starting the G30
Ensure the following has been completed before operating the G30.
Before Running the G30
Ensure the vehicle the system is mounted to is not parked on grades exceeding 20° as this will affect lubrication and air/oil separation (Figure 14).

Figure 14 — Do not exceed 20° grade New VMAC oil is clear and may be difficult to see in the sight glass.

Clear any accumulated snow or ice from the G30 (page 28) Check the compressor oil level and condition (page 52). Inspect the blowdown muffler (page 53). Inspect the Pressure Relief Valve (page 54). Inspect the compressor air filter (page 55). Inspect the engine air filter (See the Honda Owner’s Manual). Inspect the 20 A thermal breakers and ground fault circuit interrupter (GFCI)
located on the generator.

Check the engine oil level and condition (See the Honda Owner’s Manual). Check the fuel level. Do a final inspection to ensure that all fasteners and connections are tight. Check that all hoses and wiring is secure and adequately protected. Check for any fluid leaks around the unit. Ensure any pneumatic equipment is securely connected and the discharge ball
valve is closed. Ensure no power tools are turned on or plugged into the generator.
If the system has been run, ensure the compressor system has depressurized prior to restarting. The engine will not be able to start if the system is still under pressure.

Starting the Engine
What to Expect at Startup
Manually actuating the unloader valve allows air pressure to be vented to a nominal value which reduces the load on the engine. during warm up. Once the system reaches normal operating temperature, manually release the unloader valve, allowing the system to build air pressure. Normal operating engine rpm:

· When unloader is actuated (during warm up): 2,900 ± 100 rpm. · When building air pressure: 3,500 ± 100 rpm (this value can vary due to engine
load, as well as environmental conditions).
· Once system has built to full system pressure: 2,200 rpm ± 100 rpm. · When the generator is activated, the engine rpm will vary due to the load
caused by the generator, as well as environmental conditions

Starting the engine with the key switch
Do not start the system in the “GENERATOR ON” setting as this will set the engine to 3,600 rpm while starting. Run the system in “COMPRESSOR ON” until warmed up.
The G30 is designed to operate at an elevated low idle set point. This is required for optimal engine performance due to compressor and generator loads. This elevated low idle set point requires the choke to be applied during both cold and warm starts. To start the engine (warm or cold), ensure the choke is closed by confirming that the lever is all the way to the left.

1. Ensure the throttle control valve is set to “COMPRESSOR ON”.
2. If equipped with the optional VMAC Cold Climate kit, ensure the kit is turned off.
3. Close the choke by moving the choke lever all the way to the left (Figure 15).

Starting the engine with the recoil starter (pull cord)
The Honda generator produces a limited amount of amperage that is insufficient to both power the WHASP Tank cooling fan, and charge a dead battery.
If using the recoil starter due to a dead battery, allow the engine to operate at high idle, without using air (disconnect PTFE tube from unloader valve), for a minimum of 30 minutes to allow the battery to charge.
Do not start the system in the “GENERATOR ON” setting as this will set the engine to 3,600 rpm while starting. Run the system in “COMPRESSOR ON” until warmed up.

The G30 is designed to operate at an elevated low idle set point. This is required for optimal engine performance due to compressor and generator loads. This elevated low idle set point requires the choke to be applied during both cold and warm starts. To start the engine (warm or cold), ensure the choke is closed by confirming that the lever is all the way to the left.

1. Ensure the throttle control valve is set to “COMPRESSOR ON”.
2. If equipped with the optional VMAC Cold Climate kit, ensure the kit is turned off.

Compressor and Generator Operating Instructions
Do not attempt to operate the compressor and generator simultaneously! This system is designed to run either the compressor or the generator at any one time.
Compressor Operation
Start the engine and allow it to reach normal operating temperature (page 34).
While the unloader valve is actuated (under tension) the system will only build to 40 psi. Once the engine has warmed up, close the unloader valve to allow the system to build to full system pressure. Release the tension on the unloader valve (Figure 23).
Unloader valve

Figure 23 — Unloader valve
When the system is set to “COMPRESSOR ON” the engine speed will vary dependent upon air demand. This will result in voltage and frequency fluctuations which can damage some electronics. Do not attempt to operate the generator while the throttle is set to “COMPRESSOR ON” and/or the compressor is in use.
The throttle control valve should remain at “COMPRESSOR ON” (this will allow the engine speed to reduce to base idle when the system reaches maximum system pressure) (Figure 24).
Throttle control Set to “COMPRESSOR ON”

Figure 24 — Throttle control valve

VMAC – Vehicle Mounted Air Compressors

VMAC Technical Support: 888-241-2289

VMAC Knowledge Base: kb.vmacair.com

Generator Operation
To prevent damaging the generator, ensure any power tools are either powered off and/or unplugged prior to starting or shutting down the generator.
While the generator is in use, the unloader valve must remain actuated (under tension) to prevent the compressor from building air pressure. Note that with the unloader actuated, the compressor will build up to 40 psi, this is normal.
Start the engine and allow it to reach normal operating temperature (page 34).
Ensure the unloader valve remains actuated (under tension) (Figure 25).

Unloader valve
Figure 25 — Unloader valve The unloader valve must remain actuated while generator operation is selected. Turn the throttle control valve to “GENERATOR ON” (Figure 26).

VMAC Knowledge Base: kb.vmacair.com

Stopping the Engine
The engine may experience a backfire if it is shut off while the engine speed is above idle and the compressor is building air pressure. This is normal and is caused by the load on the engine during shut down. Ensure the engine is at base idle prior to shutting it off.
The exhaust system is equipped with a spark arrester.
To properly shut down the engine 1) Ensure all electrical equipment is either powered off and/or the cords are
disconnected. 2) Turn the throttle control valve to “COMPRESSOR ON”. 3) Stop all air use. 4) Ensure the system has built to full system pressure (factory setting 140 psi) and
the compressor is “unloaded”. 5) Allow the engine to run at low idle for at least 10 seconds. 6) Turn the key to the “OFF” position. 7) Move the fuel shut off valve all the way to the left to shut off the fuel (Figure 27).
Throttle control Set to “COMPRESSOR ON”
Fuel lever

Figure 27 — Shut off fuel
Improper shut down may cause compressor oil to discharge from the compressor air filter.

Ensure the fuel shut off valve is closed (all the way to the left) when the unit is not being run or before moving to a different site. Failure to do this may allow fuel to overfill the carburetor float bowl and flow into the engine’s cylinder and/or crank case causing the engine to hydraulically lock.

Recommended Accessories
While the compressor system will function without the following accessories, VMAC strongly recommends their use for optimal performance.
Receiver Tank
A receiver tank reduces the duty cycle of the compressor, and can help the G30 run tools with higher cfm requirements. It can also provide a buffer so that tools can be used immediately upon system start up.
For information on installing an air receiver tank see the “Air Receiver Tank” section of this manual on page 44.
Air receiver tanks are available for purchase through VMAC. See the “Accessory Products from VMAC” section of this manual on page 102 for more information.
Pressure Gauge
While not critical to system performance, a pressure gauge is important for fine tuning the system and simplifies any potential troubleshooting.
Install a 200 psi pressure gauge downstream of the air discharge valve.
Pressure Regulator and/or Lubricator or FRL
The compressor can produce air pressures up to approximately 135 psi
(930 kPa). It is the responsibility of the user to know the pressure and air flow requirements of the tools powered by the air compressor system.
An appropriate air pressure regulator and lubricator can be installed downstream of the air discharge valve. Failure to regulate the air pressure may cause damage to the tool.
FRL’s are available for purchase through VMAC. See the “Accessory Products from VMAC” section of this manual on page 102 for more information.
External Fuel Supply / Shut Off Valve
The use of any type of external fuel supply (e.g. gravity tank) or remote fuel shut off valves are not recommended or supported by VMAC.
Contact a Honda Engine dealer for information regarding external fuel supply or remote shut off valves.

VMAC – Vehicle Mounted Air Compressors

VMAC Technical Support: 888-241-2289

VMAC Knowledge Base: kb.vmacair.com

Air Receiver Tank
Pressure in the air receiver tank will not be relieved when the compressor system blows down. This is normal operation. Prior to performing any service work on the system, discharge any stored air in the air receiver tank.
The WHASP Tank has a built-in check valve. Use of an additional check valve is not required and may cause erratic performance.
If an air receiver tank will be used with this system, the following installation procedure must be used to prevent damage to the system.
When connecting a large capacity receiver tank, users may experience situations where the system does not unload after reaching 135 psi (See the “System Pressure Unload” section on page 27 for more information). If this happens, the regulator on the inlet valve may need to be adjusted (see page 74 for instructions).
The VMAC compressor system will automatically depressurize when shutdown. The WHASP Tank has a built in check valve that prevents blow back and moisture from the receiver tank entering the WHASP Tank. Installation of an additional check valve will cause erratic performance. While the air receiver tank can be installed at any height in relation to the WHASP Tank, the discharge hose running from the WHASP Tank must be installed as high as possible on the air receiver tank to prevent problems with condensation that may have accumulated in the receiver tank. Drain the condensed water from the receiver tank daily. Installation of an additional one-way check valve will cause erratic performance (Figure 28).
Install the line to the receiver tank as high as possible

Setup, Performance Testing and Adjustments
This system has been adjusted at the factory for general operation.
System operation can be tested using the tools that will be operated by the system or by using the VMAC Test Tool (A700052) with the 30 CFM (1/8 in) orifice in the outlet to simulate tool use (Figure 29).

JIC Adapters

Orifice

Ball valve

Install orifice here
Figure 29 — A700052 VMAC Air Test Tool
Ensure there are no leaks in the test tool. The system may not idle down or unload if there are leaks in the lines or fittings.
Disconnect all downstream equipment (hose reels, etc.) and remove the ball valve from the compressor discharge. Connect the test tool directly to the discharge fitting on the WHASP Tank.
Install the VMAC test tool at the system outlet with the 30 CFM (1/8 in) orifice. Ensure that the ball valve on the test tool is closed. Start the compressor system and allow the engine to run until it is at operating
temperature. Ensure the tension on the unloader valve is released to allow the compressor to
build to full pressure. Observe the pressure gauge, it should indicate approximately 135 psi (factory
setting). Slowly open the ball valve on the test tool and observe the operation. The
engine speed should increase when the pressure drops to 110 psi (25 psi below system pressure). With the ball valve fully open, the pressure should stabilize above approximately 100 psi (this simulates a tool operating at 25 CFM). Close the ball valve to allow the system pressure to rise. Once testing is complete, follow the normal shut off procedure.

Engine rpm Adjustment
Adjusting the engine speed is not an approved procedure. Any damage or performance issues caused by unauthorized engine rpm adjustment will not be covered under warranty.
Lowering the engine rpm will decrease the cfm output and will cause the engine to stall, while increasing the engine rpm may damage the engine.
Any adjustment to the engine speed may result in the generator operating outside of it’s designed frequency and voltage specifications, damaging the generator and/or any equipment attached to it.
The engine “low idle” and “high idle” screws are set at the factory and do not require adjustment. The throttle actuator will automatically raise and lower the engine speed dependent upon air demand.

Routine Maintenance
The G30 must be run a minimum of once every 30 days for at least 30 minutes to prevent impact damage and premature bearing failure in the compressor due to vibration. Regularly running the system will also help to vaporize and exhaust any water that has condensed and accumulated in the WHASP Tank.
In order to maintain the VMAC warranty, VMAC’s maintenance schedule must be followed. Only genuine VMAC parts can be used to maintain the system.
With proper maintenance, the likelihood of premature failure or component replacement can be drastically reduced.
The most critical aspect of maintenance is proper air filtration, clean oil, and regular use. If any particles enter the compressor, they can score the rotors and contaminate the roller bearings in the compressor. Any contamination will cause rapid and severe damage to components.

In order to maintain the warranty on the G30, use only genuine VMAC parts to service the system.

Maintenance Schedule

Refer to the Honda Owner’s Manual for the engine maintenance schedule and instructions.

The following maintenance schedule must be observed to maintain both the “Standard” and “Lifetime” VMAC warranties and to assure proper performance and long service life of the system. In the event of a warranty claim, VMAC may request service records.

Inspecting and Replacing the Blowdown Muffler
Read the “Maintenance and Repair Safety” section prior to performing any work on the system (beginning on page 51). Wear appropriate Personal Protective Equipment and follow all industry standard safety practices. The Blowdown Muffler is a regular service item and must be replaced every 400 hours or 1 year, whichever interval occurs first. Visually inspect the blowdown muffler for evidence of corrosion or loss of functionality. Ensure the muffler allows the blowdown to pressurize the system. To test the blowdown system and muffler: Turn the system on and allow it reach full system pressure (factory setting 135 psi). Turn the ignition key switch to “OFF”. Listen for the pressurized air to blowdown through the muffler on the WHASP Tank. Blowdown should be completed in approximately 20 seconds. If the muffler is showing signs of blockage, contact a local VMAC dealer for a replacement.

Inspecting and Replacing the Pressure Relief Valve
Read the “Maintenance and Repair Safety” section prior to performing any work on the system (beginning on page 51). Wear appropriate Personal Protective Equipment and follow all industry standard safety practices.
Do not use the pressure relief valve as a means of depressurizing the compressor system. Doing so will prematurely wear the internal spring or the seat, preventing the valve from maintaining normal system pressure.
The Pressure Relief Valve is a regular service item, and must be replaced every 400 hours or 1 year, whichever interval occurs first. Inspect the pressure relief valve for signs of corrosion or loss of functionality. To test the pressure relief valve functionality: Visually inspect the valve and ensure it is not corroded and that the vent holes
are not plugged. Turn the system on and allow it reach full system pressure (factory setting
135 psi). Ensure that air does not leak out of the valve. Air leaking from the pressure
relief valve when system pressure is at or below 135 psi indicates that the spring in the valve is worn and the valve must be replaced. If the pressure relief valve is showing loss of functionality, contact a local VMAC dealer for a replacement.
A replacement pressure relief valve is included with the VMAC 400 hour service kit.

General Service Information

Read the “Maintenance and Repair Safety” section prior to performing any work on the system (beginning on page 51).
Wear appropriate Personal Protective Equipment and follow all industry standard safety practices.
If the system is cold, operate the compressor system for a few minutes to bring the compressor oil to operating temperature. Warming the system will allow the oil to flow better and will also help to suspend contaminants in the oil allowing them to be removed from the system with the old oil.
Shut the compressor down.
Ensure the system is fully depressurized prior to beginning any service work.
Check the old oil for any evidence of metal filings or contamination. If any metal filings are found, flush the hoses and the ASP using the VMAC flushing kit (P/N: A700214).
PTFE Tubing, Loom, and Push-To-Connect Fittings
· PTFE tubing should only be cut using proper tubing cutters. Side cutters, utility
knives, etc. will deform the tube, preventing a proper seal (or leave sharp edges which cut the internal O-ring).
· When applying loom to the PTFE tube, leave approximately 1 in between the
loom and the fitting.
· Ensure the tube is clean, cut at 90° and that there are not sharp edges. · Lubricate the tube and, with the collet pushed into the fitting, firmly push he
tube into the fitting until the tube is fully seated.
· Slide the collet out, away from the body of the fitting to lock the tubing in
place.
· Ensure the tube does not have any “play” to prevent the O-ring from wearing.

Cut the tube squarely, using only proper tubing cutters as side cutters
will deform the tube.

Slide the collet out once the tube is fully inserted

System Adjustments
The G30 is tuned at the factory for optimum performance and should not require further adjustment. This information is provided to assist operators in returning the system to factory specifications in the event that it has been field adjusted and/or no longer performs as intended. When tuned correctly, the G30 will operate at high rpm until the unit has built to full system pressure (135 psi) and then will “unload” and reduce engine speed to base idle. In order for the system to “unload” and reduce engine speed, both the inlet pressure regulator, and the unloader valve must be adjusted to the correct values.
Prior to making any adjustments, run the system for a minimum of 3 minutes or until the WHASP Tank fan turns on, as all adjustments must be made while the system at operating temperature.
Prior to adjusting the unloader valve, the inlet pressure regulator must be set to 140 psi.
Adjusting the Inlet Pressure Regulator
Read the “Maintenance and Repair Safety” section prior to performing any work on the system (beginning on page 51). Wear appropriate Personal Protective Equipment and follow all industry standard safety practices. Disconnect the PTFE tube connected to the unloader valve. Remove the push-to-connect fitting from the unloader valve and plug the valve using a 1/8 in NPT plug (Figure 48).

Compressor Regulation and Throttle Actuator Testing
Throttle Control
VMAC configures the Honda engine throttle to be wide open in its neutral state (0 psi). Engine rpm is controlled via the throttle actuator which is operated by air pressure from the unloader valve.
Once air pressure at the ball valve and unloader valve (“downstream pressure”) reaches 135 psi, the throttle actuator closes the throttle, reducing engine speed to idle. “Downstream pressure” opens the discharge valve diaphragm, via the 1/4 in PTFE tube, and allows air pressure to close the inlet valve poppet: (Figure 52, Figure 53, Figure 54).

Throttle Control Testing
Read the “Maintenance and Repair Safety” section prior to performing any work on the system (beginning on page 51). Wear appropriate Personal Protective Equipment and follow all industry standard safety practices.
The air pressure (inlet valve) and engine rpm (throttle actuator) are controlled by the unloader valve. As air pressure from the unloader valve increases, it forces the throttle actuator to reduce engine rpm. Once the system has built to full system pressure (135 psi) the force from the unloader valve will move the throttle to base idle. While the system is building air pressure, the PTFE test tool gauge will indicate 0 psi and the throttle will be wide open. Once downstream pressure reaches 135 psi it will actuate the unloader valve which opens the discharge valve. The PTFE test tool gauge will indicate 135 psi and air pressure from the discharge valve will force the throttle closed. When downstream pressure drops below 110 psi the discharge valve will close (the PTFE test tool gauge will indicate 0 psi) and allow the throttle to return to its neutral state of wide open.
The following testing is for systems set at factory pressure (135 psi).
With the system off and depressurized Remove the WHASP Tank shroud. Remove the ball valve fitting (if applicable) to accommodate the test tool. Install a test tool on the system outlet (Figure 60).

Start the engine (see page 34), and monitor both pressure gauges:

1. As the pressure indicated on the VMAC test tool gauge reaches 135 psi, the gauge connected to the 1/4 in PTFE tube should indicate 135 psi. If the pressure on the gauge connected to the 1/4 in PTFE tube does not increase, confirm the unloader valve is properly adjusted. If adjusting the unloader valve (starting on page 74) does not resolve the issues, the discharge valve needs to be replaced.
2. As the pressure indicated on the PTFE Test Tool gauge connected to the 1/4 in PTFE tube reaches 135 psi, the throttle actuator rod should move the throttle to the right and the engine rpm should decrease. If the throttle does not move, diagnose or replace the throttle actuator.
3. When the system pressure indicated on the VMAC test tool reaches 135 psi, the pressure indicated on the gauge connected to the 1/4 in PTFE should hold steady at 135 psi. If the pressure does not hold, check for air leaks or a defective throttle actuator.
4. Slowly open the test tool ball valve. The pressure on both gauges should drop at approximately the same rate until pressure at the discharge valve reaches 110 psi. Once the discharge valve pressure drops to 110 psi, the discharge valve will close and the PTFE test tool gauge will indicate 0 psi. If the pressures do not drop at the same rate, the discharge valve may be plugged.

5. Close the ball valve on the VMAC test tool. 6) Turn the VMAC throttle control to “GENERATOR ON”. 7) Air pressure on the from the 1/4 in throttle tube will vent to atmosphere via the
   sintered muffle mounted to the bottom of the VMAC throttle control. 8) Engine speed should increase to maximum rpm and remain there as long as the
   VMAC throttle control is set to “GENERATOR ON”.
   Poppet Valve
   If the inlet or poppet O-ring is damaged or missing, the compressor may over pressurize and may cause a compressor oil leak.
   Air pressure generated by the compressor is controlled mechanically via the inlet valve poppet. When the inlet valve poppet is open, the compressor will build air pressure (Figure 63).
   Poppet O-ring
