  • Page 21: Installing The Air Oil Separator Tank (Aost)

    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.

  • Page 24: 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.

  • Page 44: Testing The Installation

    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 45 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.
  • Page 46 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).

  • Page 47: Performance Testing And System Adjustments

    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 46).
