(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.

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.
Cut the tube squarely, using only the tube is fully inserted proper tubing cutters as side cutters will deform the tube. O-ring Figure 23 — Push-to-connect fittings VMAC - Vehicle Mounted Air Compressors VMAC Technical Support: 888-241-2289 VMAC Knowledge Base: kb.vmacair.com...

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.
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. •...

Close all open air valves/tools and allow the system to build to full pressure (factory default: 150 psi). • Allow the engine speed to reduce to VMAC base idle for at least 10 seconds. • Turn the compressor off using the remote momentary “OFF” switch.
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 53 for a list of products available for purchase through VMAC.
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...
Check all wiring for security and protection. Ensure nothing is touching the compressor body. ☐ Install the VMAC Air Test Tool (P/N: A700052) with the 70 cfm (0.190 in) orifice installed and the ball valve closed. ☐ Ensure all of the compressor outlets are closed.
Page 49
Press the “ON” button on the control box. ☐ When the VMAC system is first engaged, the engine speed should increase to approximately 2,500 rpm and then drop down to VMAC base idle (approximately 1,000 rpm) once system pressure is reached.
Page 50
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).
Performance Testing and System Adjustment 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 70 cfm (0.190 in) orifice in the outlet to simulate tool use (Figure 50).

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.
