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 warrant 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

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.

Special Tools Required

None

All fasteners must be torqued to specifications. Use manufacturers’ torque values for OEM fasteners. The torque values supplied in Table 1 are intended for VMAC supplied components, or for use as a guide in the absence of a torque value provided by an OEM.

Warning: Apply Loctite 242 (blue) to all fasteners (except nylon lock nuts) unless otherwise stated.

Maintenance and Repair Safety

Warning

Prior to performing any service, ensure the transmission in “PARK” with the parking brake applied and the wheels chocked.
It is impossible to warn of all the possible hazards that may result from operating, servicing, or repairing this system. Wear all appropriate Personal Protective Equipment and follow all industry standard safety practices.
Confirm that the system is depressurized and has cooled prior to performing any service work.
Never use flammable solvents to clean any components. If a flammable solvent has been used, rinse the component thoroughly with water and dry it before reinstalling it to prevent the possibility of explosion.
Use only genuine VMAC parts to maintain the system. Genuine VMAC parts are designed to work with the high pressure and heat generated by the compressor. Substituting genuine VMAC parts may void the warranty and could cause equipment damage, injury, or death.
This information is intended for people with mechanical trade certification who have the tools and equipment to properly and safely perform the service or repair. Do not attempt to service or repair this system without the appropriate mechanical training, knowledge and experience. Follow all safety precautions and industry standard “best practices”.

Safety Check List

Open the ball valve or connect an air tool to the system to ensure all the stored air is released.
Gently pull up on the ring on the pressure relief valve to confirm the system is depressurized.

Warning: 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.

General Service Information

Warning: Read the “Maintenance and Repair Safety” section prior to performing any work on the system (beginning on page 8). Wear appropriate Personal Protective Equipment and follow all industry standard safety practices.

If the system is cold, bring the engine to operating temperature and then operate the compressor system for a few minutes to bring the compressor oil to operating temperature. Warming the system will improve oil flow and will allow the oil to flow better and will also help to suspend contaminants in the oil, so that they can be removed from the system with the old oil.
Shutdown the compressor.
Shutdown the engine.
Ensure the system is fully depressurized prior to beginning any service work.
Observe all safety procedures relating to moving belts, hot oil and compressed air. Use all appropriate Personal Protective Equipment and follow all industry standard safety practices.
Check the old oil for any evidence of metal filings or contamination. If any metal filings are found, flush the hoses and the AOST using the VMAC flushing kit (P/N: A700214).

Push-To-Connect Fittings

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.

Inspecting the Drive Belt

Warning

Read the “Maintenance and Repair Safety” section prior to performing any work on the system.
Wear appropriate Personal Protective Equipment and follow all industry standard safety practices.

Check the Front End Accessory Drive (FEAD) belt for evidence of glazing, cracks, missing or damaged ribs or damage to the belt edges and surface. If the FEAD belt is damaged, install a new FEAD belt. Inspect the pulley(s), idler(s), and tensioner for damage. If any of the components show cracks, chipping, impact damage or any other indications of physical damage, replace the component. If the damage indicates possible misalignment, check the pulley/idler/tensioner alignment. If the pulleys are not properly aligned, check all fasteners to ensure that they are properly torqued and that there are no loose or worn components. See the system specific Illustrated Parts List (IPL) for VMAC supplied part numbers.
