Page 23: Installing The Air Oil Separator Tank (Aost)
(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. - Page 24 Using the (×2) supplied 3 in × 1/4 in pinch bolts and install them into the mounting clamps.

Page 26: Hose Requirements
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. -

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... -
Page 49: Testing The Installation
Press the “ON” button on the control box. The green LED should come on and the compressor clutch will engage, this should be audible. On systems equipped with VMAC’s digital throttle control, the “PRK BRAKE” LED will remain illuminated at all times, regardless of park brake position. - Page 50 ☐ 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 ball valve closed. ☐ Ensure all of the compressor outlets are closed. ☐ Ensure the parking brake is engaged and the transmission is in “PARK”.
- Page 51 No user input is required. Operators may however notice that while the system is at full system pressure and the vehicle is at base VMAC idle, the vehicle engine speed may drop by a few hundred rpm and then return to normal VMAC base idle as the VMAC digital throttle control auto calibrates.
- Page 52 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).

The rpm adjustment range is dependent upon the DTM model (Table 2).
- Page 58 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.
