General Information

Optional Equipment Compatibility
While VMAC strives to design systems compatible with optional OEM equipment (such as running boards), it is impractical to develop systems that accommodate every OEM and aftermarket option or add-on. Whenever possible, VMAC endeavors to advise of compatibility issues in the “Additional Application Information” section of the manual. Even when specific optional equipment is determined by VMAC to be incompatible, it does not preclude the vehicle upfitter or end user from modifying the optional equipment to make it compatible with the installed VMAC system. VMAC does not warranty or accept responsibility or liability for the fitment, function or safety of any products modified in any way not expressly outlined in the installation manual.

Before Starting
Note and label all parts that are removed from the vehicle as many of the OEM parts will be reused during the installation of the VMAC system.
Read this manual prior to beginning the installation to ensure familiarity with the components and how they will fit on the vehicle. Identify any variations from the application list such as vehicle model, engines, or optional equipment (e.g., dual alternator, active steering assist, etc.).
Open the package, unpack the components and identify them using the Illustrated Parts List (IPL) included in the Fastener Pack.

Hose Information
Depending on other installed equipment, it might be necessary to move the air/oil separation tank from its intended location. The hoses used in VMAC compressor systems have a specific inner liner that is compatible with VMAC compressor oil. Use of hoses other than those supplied or recommended by VMAC may cause compressor damage and may void your warranty. Please contact VMAC for replacement hoses and further information.
Ordering Parts
To order parts, contact a VMAC dealer. The dealer will ask for the VMAC serial number, part number, description and quantity. Locate the nearest dealer online at www.vmacair.com/dealer-locator or call 1-877-912-6605.

Relocating the ABS Hydraulic Control Unit (HCU)
Depending on the application, the following steps may not be necessary. If the HCU is mounted towards the firewall (Figure 19 on page 18), proceed to the next chapter. If the HCU bracket is mounted using the holes shown in Figure 14, follow the steps in this chapter.
Failure to follow these instructions may result in brake system contamination, component damage, and/or death.
If there is any concern that air may have entered the brake system, consult a local Ford dealer or licensed repair facility for vehicle specific HCU brake bleeding instructions.
Use extreme caution while adjusting the brake lines to prevent damaging them. If there is any concern that the brake lines may have been kinked or damaged in any way, contact a local Ford dealer or licensed repair facility to have the issues rectified.
Do not allow the brake master cylinder to run dry during these steps as the master cylinder may be damaged if operated without fluid.
Use only clean brake fluid from an unopened container that meets Ford specifications.
It may be necessary to rotate the brake lines that connect the master cylinder to the ABS HCU module to avoid kinking the flexible rubber hoses as the HCU is shifted to its new position. The following process will help avoid air entering the brake system as brake fluid will be forced out of the system rather than air permitted to enter the system. Do not pump the brakes at any time while the brake lines are loose as air may be drawn into the system. Have an assistant gently depress the service brake as the brake line is loosened, rotated into a relaxed position and then quickly retightened. Adjust one brake line at a time. If there is a significant amount of brake fluid escaping from the fitting, the pedal is being pressed too hard and/or the fitting has been loosened too much.

Installing the Air Oil Separator Tank (AOST)
Dependent upon other installed equipment, it may be necessary to move the AOST from its intended location. The hoses used in VMAC compressor systems have a specific inner liner that is compatible with VMAC compressor oil. Use of hoses other than those supplied or recommended by VMAC may cause compressor damage and may void the warranty.
The AOST must be level for proper air/oil separation, and to ensure that the oil level will display accurately in the sight glass.
Apply Loctite 242 (blue) to all fasteners (except nylon lock nuts) unless otherwise stated.
Installing the AOST
Prior to proceeding with the AOST installation, review this chapter, as well as the A700250 accessory instructions (included with this kit), to determine the AOST mounting location. Note that the A700250 accessory is not compatible with pickup trucks or chassis cab applications equipped with a midship fuel tank. The AOST will either mount in the “mid ship” location (A700250) or to the passenger side frame rail behind the transmission crossmember (Figure 59).

Hose Requirements

Only attempt to shorten the supplied hose if there is access to the appropriate equipment. Do not attempt to cut the hose and splice it using hose clamps.
VMAC Compressor oil will degrade rubber lined hoses, use only hoses with an AQP elastomer type liner. Contact VMAC Technical Support at 1-888-241-2289 for further information.
The PTFE tubes and AQP elastomer lined hoses are specifically designed to work with VMAC compressor oil and at compressor operating temperatures.
Based on the desired location of the AOST, the hose lengths provided with this system may not be ideal. VMAC suggests first trying to adjust the AOST within its mounts to take up any excess slack in the hoses. If this is not effective, the hoses can be shortened or replaced as necessary, or hose extenders can be used.
VMAC recommends shortening these hoses as a preferred alternative to coiling up and securing the excess. Shorter hose length will maximize system performance.
Avoid using 90° fittings wherever possible as they cause flow restrictions and negatively impact performance.
The following hoses are included with this compressor kit:
· 1/2 in × 54 in. · 1/2 in × 85 in. · 1 in × 87 in. · 1/4 in (PTFE Tube): Shipped with the A700250 AOST Relocation Kit. Cut to
length as required.
· 3/16 in (PTFE Tube): Shipped with the A700250 AOST Relocation Kit. Cut to
length as required.
If longer hoses are required:
To order parts, contact a VMAC dealer. The dealer will ask for the VMAC serial number, part number, description and quantity. See page 6 for ordering information.
· Eaton Aeroquip hoses with an “AQP” type inner liner are required. · OTC fittings are required for the VMAC supplied hose. · Push-lock fittings are suitable if FC332 hose is used. · If Push-lock fittings are being used, do not use hose clamps as they will
damage the hose and cause leaks.

Routing and Connecting the Hoses

When routing hoses, ensure cap plugs are installed so that contaminants do not get in the line. Take care when routing hoses, as a hose failure may damage the compressor and/or cause injury.
All hoses, tubes and wires that are installed, rerouted or shifted during the installation must be secured so that they do not contact any hot, sharp or moving parts. Use rubber coated P-clips wherever possible. Follow the routing suggestions in this manual and cover all hoses with plastic loom.

Ensure there is sufficient slack in the hose routing to allow for normal engine movement.

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 firmly push it into the fitting so that the tube fully seats
in the fitting.
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

Adding Oil to the System
The VMAC supplied and approved compressor oil must be used in this system. Failure to use this special oil will result in damage to the compressor and will void warranty. Do not overfill the system. Overfilling the system with oil can flood the sight glass window and make the system appear empty.
Lower the vehicle from the axle-stands. Ensure the vehicle is parked on level ground. Remove the oil filter from the AOST and discard the cardboard warning tag.
Apply a light film of compressor oil to the filter gasket and thread the filter onto the AOST until the gasket makes contact. Tighten the filter an additional 3/4 to 1 turn after the gasket contacts the base.
Remove the cap from the oil-fill port located on the Inlet valve (Figure 86).

Installing the Control Components
Best Practices
· To confirm a good ground, use an ohm meter to measure the resistance
between the ground point and the negative battery terminal. Resistance should be less than 1 .
· Route all wires to ensure they will not contact hot, sharp or moving parts
(including the park brake mechanism, steering column, and pedals).
· Before drilling any holes ensure there are no OEM wires, hoses, or components
that may be damaged.
· Do not use a test light to probe for power on vehicle circuits, the increased
current draw of the test light may damage components.
· VMAC recommends using only sealed crimp and solder butt connectors for all
electrical connections.
· To ensure a durable connection, use only good quality crimping tools. · Apply loom to all wiring:
Use high temperature loom in areas where high temperatures may be expected.
Use spiral loom in areas with high vibration.
In-line Butt Splice Connections
· Cut the wire approximately 2 in from the connector. · Strip approximately 3/8 in from the end of both sides of the cut wire, as well
as from the end of the wire being spliced in-line.
· Twist the wire to be spliced in-line, together with the “live” side of the wire (not
the wire attached to the connector).
· Slide the butt connector onto the twisted wires and crimp it. · Insert the “connector side” of the wire into butt connector and crimp it. · Lightly tug the wires to ensure they are properly crimped. · Using a heat gun, carefully apply heat to the butt connectors to seal the
connection.

· Slide the OEM (live) wire into the slot on the large cap as far as it will go. · Thread the tap (barrel with pin) over the slotted cap, ensuring the pin is
centered on the wire. Firmly tighten the tap.
· Strip approximately 3/8 in from the end of wire. · Unscrew the small cap. · Twist the wires together and insert the wire into the cap. · Deflect the wires to one side. · Insert the cap into the tap, ensuring the wires enter one side of the metal core. · Ensuring the wire does not slip out of the cap, push and turn until the threads
catch and firmly tighten the cap.
· Ensure all of the connections are firmly tightened by hand (overtightening will
cause the threads to strip).
Tying into OEM connectors
Some OEM connectors may have locking tabs that must be disengaged prior to inserting a crimped connector.

Recommended Accessories
While the compressor system will function without the following accessories, VMAC strongly recommends their use for optimal performance.
See the “Accessory Product” section of this manual on page 87 for a list of products available for purchase through VMAC.
Receiver Tank
An air receiver tank provides a buffer as it gives the compressor time to react by increasing the engine speed and producing air before the tool stalls. It also has the advantage of lowering the duty cycle of the compressor system.
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 175 psi (1207 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.

VMAC – Vehicle Mounted Air Compressors

78

VMAC Technical Support: 888-241-2289

VMAC Knowledge Base: kb.vmacair.com

Air Receiver Tank
If an air receiver tank will be used with this system, a check valve (not supplied) must be installed to prevent damage to the system. Once a check valve is installed, 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.
If an air receiver tank will be used with this system, the following installation procedure must be used to prevent damage to the system.
The VMAC compressor system will automatically depressurize when it is shutdown, therefore the hose from the VMAC AOST to the air receiver tank must have a check valve installed; this prevents blow back and moisture from the receiver tank entering the AOST
While the air receiver tank can be installed at any height in relation to the AOST, the discharge hose running from the AOST 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 (Figure 114).
Drain the condensed water from the receiver tank daily.
Install the line to the receiver tank as high as possible

Allow the vehicle to run for a minimum of 30 seconds.
Calibrate the Ford ECU:
Rev the vehicle to 2,000 rpm and allow it to return to base idle. Shut down the engine. Start the engine. Repeat this process (×2) more times. Allow the vehicle to reach operating temperature. Turn on the compressor.
The VMAC digital throttle is a “slow ramp” throttle. Each time the system is powered on, it will quickly increase engine speed to 1,500 rpm; then increase to maximum VMAC rpm over 8 seconds (provided the system has not reached full system pressure before maximum VMAC rpm is reached).
After the initial slow ramp, the throttle will respond normally to air demand
When the VMAC system is first engaged, the engine speed should increase to
1,500 rpm and then drop down to VMAC base idle (approximately 1,000 rpm) once system pressure is reached. With the system running, check for:
Coolant leaks. Compressor oil leaks. Allow the compressor to run until the system reaches full system pressure. Engine speed should reduce to between 900 rpm to 1,000 rpm. Turn off the compressor. Shut down the engine. Check the compressor oil level after the engine has been shut down and the oil
level has had time to stabilize.
Ensure any stored air is drained from the system prior to adding oil.
Add oil as necessary to bring the level to the “FULL” line in the sight glass and
check for leaks.
Start the engine. Turn on the compressor and allow it to build to full system pressure. Release the park brake.
· The control box should read “PARK BRAKE”, the compressor clutch should
disengage and engine speed should reduce to OEM idle.
Re-engage the park brake and start the compressor. Allow engine speed to stabilize after re-engaging the compressor.

With the brake pedal firmly depressed, shift the truck into “REVERSE”.
The engine speed reduces to OEM base idle (Approximately 650 rpm). The green LED on the control box remains illuminated. The “STATUS” and “PRNDL” LED’s on the digital throttle control will turn off
and engine speed will reduce to base idle.
Shift the vehicle back into “PARK”. Cycle the compressor off, then on again to reset the safety parameters. Repeat these steps in all gear selector positions to ensure the engine
speed does not increase unless the gear selector is in “PARK”.
Digital Throttle Auto Calibration
When first installed, the VMAC digital throttle will perform an autocalibration as it adjusts to the vehicle’s tune, this process takes approximately 3 minutes.
Remove the orifice from the VMAC Air Test Tool. Open the ball valve slowly, until the system maintains approximately 85 psi. Allow the system to run for 3 minutes while the VMAC digital throttle calibrates
itself. During this time, engine speed may gradually increase until achieving the maximum VMAC rpm (1,800 rpm). If the throttle over revs, drops to OEM base idle (approximately 600 rpm), and displays 4 red LED pulses, perform the steps listed under “High rpm Error (4 Red LED pulses)” on page 85.
Close the ball valve. Allow the compressor to run until the system reaches full system pressure. Confirm all air valves are closed and the system has no air leaks. Turn off the compressor. Ensure any stored air is drained from the system.
Final Testing
Ensure the following has been completed:
Operate the system with an air tool (or the VMAC Air Test Tool with the
appropriate orifice installed) for at least 1/2 hour (1 hour preferred).
Road test the vehicle for approximately 14 miles (20 km). Observe the compressor operation to ensure that the belt alignment is good
and nothing is rubbing or contacting hot components.
Check all components, connections and fasteners once the engine is turned off
and the system has cooled.
Check the coolant level after the engine has been operated. Check the compressor oil level after the engine has been shut down and the oil
level has had time to stabilize.

Figure 115 — A700052 VMAC Air Test Tool
Disconnect all downstream equipment (hose reels, etc.) and connect the test tool directly to the discharge fitting on the AOST.
Ensure there are no leaks in the test tool. The system may not idle down if there are leaks in the lines or fittings.
Install the VMAC test tool at the AOST outlet with the 150 cfm (0.250) orifice. Ensure that the ball valve is closed. Place the transmission in “PARK” and fully apply the park brake. Allow the engine to run until it is at operating temperature. Turn on the air compressor system and allow it to operate until the oil is warm. Observe the pressure gauge. Pressure should be approximately 150 psi.
Open the ball valve on the test tool and observe the engine tachometer:
Engine speed should increase to approximately 1,800 rpm. Close the air valve slowly to allow the system pressure to rise. Once system pressure is at maximum, slowly open the ball valve on the test
tool until the pressure on the gauge begins to drop. Engine speed should ramp when the pressure drops to approximately 140 psi.

Digital Throttle Control Operation and Adjustments
The VMAC digital throttle is a “slow ramp” throttle. Each time the system is powered on, it will quickly increase engine speed to 1,500 rpm; then increase to maximum VMAC rpm over 8 seconds (provided the system has not reached full system pressure before maximum VMAC rpm is reached).
After the initial slow ramp, the throttle will respond normally to air demand.
The throttle control is configured at the factory for optimum performance at maximum cfm. In applications where maximum cfm is not required, or noise is a concern, the throttle control can be adjusted to reduce the maximum VMAC rpm.
Safety features
The throttle control has built in safety features that will disable the system if an unsafe condition is detected, or either of the lock out parameters is not met (the vehicle must be in “PARK” and the park brake must be engaged).
If an unsafe condition is detected, the “STATUS” LED will turn off, and engine speed will return to idle. Once all unsafe conditions have been removed, the system must be cycled off, then on again to reset it. Once the system powers up, the “STATUS” LED will illuminate, and the system will operate normally.

Figure 116 — Throttle control
If the park brake is released, or the vehicle is placed in gear, the “STATUS” LED and the corresponding lockout LED will turn off and the throttle control will deactivate. This will reduce engine speed to base idle.
In order to activate the system again, re-engage the appropriate lockout and cycle the VMAC “OFF” then “ON” via the control box.

MAX RPM
The cfm produced by the system is directly related to engine speed; this system delivers 83 cfm at 2,400 rpm, and 115 cfm at 3,200 rpm. Maximum VMAC rpm can be adjusted between 1,500 rpm and 3,200 rpm (in 50 rpm increments) via the “” or “” buttons in the “MAX RPM” column.
If the system is at full system pressure while the rpm is being adjusted, the engine speed will increase to the new value for 4 seconds, then return to base idle.
RAMP UP PRESSURE
“RAMP UP PRESSURE” is the amount of pressure the system will drop before the engine speed is increased to generate air; as air continues to be used and the pressure drops, engine speed will increase until maximum VMAC rpm is achieved.
“RAMP UP PRESSURE” is set to 140 psi (10 psi below the factory default maximum system pressure of 150 psi). This allows for a small amount of air use without the need to increase engine speed.
“RAMP UP PRESSURE” should only be adjusted if the maximum system pressure is changed (via the inlet regulator). To maintain proper performance, and rapid response to air demand, ensure the “RAMP UP PRESSURE” is set at no more than 20 psi below the maximum system pressure.
The “RAMP UP PRESSURE” can be set to “100 PSI”, “120 PSI”, “140 PSI”, or “160 PSI via the “” or “” buttons in the “RAMP UP PRESSURE” column; an LED will illuminate beside the setting that has been selected.
High rpm Error (4 Red LED pulses)
4 red LED pulses indicates a high rpm error from the throttle, which occurs when the VMAC throttle control is having difficulty calibrating to the vehicle.
To recalibrate the VMAC throttle, perform the following steps:
Shut down the VMAC system. Disconnect the 4 pin connector (pressure sensor) on the throttle. Turn the VMAC system on. The compressor will start to build air but the engine
speed will not increase and the throttle will report a “Pressure” error (3 red pulses).
Press the “MAX RPM” button (×20) times. Shut down the VMAC system. Reconnect the 4 pin connector (pressure sensor) to the throttle. Turn the VMAC system on, allow the system to build to 150 psi. After 20seconds, slowly open the ball valve enough to maintain approximately
90 psi.
After 20 seconds, the engine speed should settle to approximately 1,500 rpm. Press the “MAX RPM” button repeatedly until the engine speed reaches
2,200 rpm (allow the engine speed to respond between each press of the button).

VMAC Knowledge Base: kb.vmacair.com

After engine speed has stabilized at 2,200 rpm for approximately 10 seconds,
close the ball valve and allow the system to build to full system pressure.
Turn off the system.
The system should work normally now.
Factory Reset
The throttle control can be reset to factory default values via a button inside the throttle control box.
To perform a factory reset, turn the system on and allow the engine speed to drop to VMAC base idle (approximately 1,000 rpm). Using a paper clip (or similar object), push and hold the factory reset button for 5 seconds. All of the LED lights will illuminate for several seconds while the settings revert to their defaults. Once the LED’s return to their normal state, the system is ready for use again.
