  • Page 35: 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 36 AOST orientation is critical. The arrow on the blowdown cap at the rear of the tank must be pointing up to prevent compressor failure due to oil starvation, or oil in the discharge air. VMAC - Vehicle Mounted Air Compressors VMAC Technical Support: 888-241-2289 VMAC Knowledge Base: www.kb.vmacair.com...

  • Page 37: Hose Requirements

    Dependant upon 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 41: Adding Oil To The System

    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.

  • Page 47: Recommended Accessories

    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.

  • Page 48: Completing The Installation

    Remove the protective coverings and reinstall the air intake resonator. ☐ Cover all VMAC under-hood wiring with high heat plastic loom (if not done previously). Secure the harness with cable ties as needed to avoid hot, sharp or moving components.

  • Page 49: 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 50 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 51 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 52: 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 53).

  • Page 53: Digital Throttle Control Operation And Adjustments

    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...
  • Page 54 The cfm produced by the system is directly related to engine speed; this system delivers 70 cfm at 2,400 rpm. Maximum VMAC rpm can be adjusted between 1,500 rpm and 2,500 rpm (in 50 rpm increments) via the ““ or “” buttons in the “MAX RPM” column.
