VIAIR Constant Duty (Universal) - Manual (Page 3)

MOUNTING AND WIRING
1. Disconnect ground cable from vehicle’s battery.
2. Position the air compressor in the location where it will be mounted. If brake booster mounting
is provided/desired, based on type of ADA System, install brake booster bracket either with the
compressor in place, or afterwards if this eases installation.
3. Note: If your ADA System is equipped with a brake booster bracket, you must remove the
corresponding hardware from the brake booster to properly install the booster bracket. Reinstall
all removed hardware, following the manufacturer’s torque specifications for installation of any
hardware removed.
4. For 2007-2011 JK Models, the compressor intake filter should face the vehicle’s firewall.
Quick connect coupling should face radiator support.
5. For Universal Models, mount air compressor to either a flat surface or to the brake booster
mounting bracket with the bolts, nuts, washers, and locking washers provided.
6. NOTE: For remote inlet air filter installation, refer to instructions included in the Remote Inlet
Air Filter Pack.
7. Route the provided wiring harness from the mounting location of the ADA System to the battery
of your vehicle. Secure the harness as needed at several points, to avoid abrasion and other
possible damage resulting from movement during vehicle use. Special care must be taken when
routing the harness through sheetmetal to avoid abrasion.
8. Make sure that your compressor setup is properly fused by installing the provided fuse in the
wiring harness assembly.
9. Before connecting to power source, re-check your system to make sure that all electrical
connections are made properly.
10. Connect power lead of the wiring harness to the battery. It is recommended to provide switched
power for the system, that is only turned on when the ignition of the vehicle is also energized in
case of any air leaks that may allow the system to turn on and drain your battery during periods
when the vehicle might remain parked. This is especially important when using a small reservoir,
as is supplied with all ADA Systems.
11. Connect the ADA System’s Delphi connector to corresponding Delphi plug connector of the
wiring harness provided.
12. Ensure that the drain valve located on the underside of the ADA System reservoir is closed.
13. When power is made available to the ADA system, the system will automatically turn on
and fill the ADA reservoir.
14. When the cutoff pressure of the ADA System has been reached, the system will
shut off automatically.
15. Inspect all air line connections for leaks with soap and water solution. If a leak is detected, the
connection may not be made properly. Re-do any connections that are leaking. The use of
thread locker is recommended for all fittings. (Avoid the use of Teflon tape).
