VIAIR Onboard Air Hookup Kit - Manual (Page 6)

13. Connect to air compressor is simple and easy with the Quick Connect Coupler by applying the
1/4” (NPT) Female Quick Connect Stud at the end of the compressor’s leader hose.
FYI: This quick connect setting is designed to have the option to air up tires directly
from air compressor by connecting an air hose with Quick Connect Coupler to the applied Quick
Connect Stud on compressor’s leader hose. (See Fig. 3)
NOTE: Compressor, fittings, & air hose connected to the compressor will become very
hot during and immediately after use. Do not touch with bare hands. Use gloves if necessary.
14. Before connecting the power wire to power source, check to make sure the On/Off switch
on dash panel gauge is in the OFF position. Connect the ring terminal of the power wire to
power source. (See Fig. 4) (This is the wire described in Step 11, which is connected to the ON/
OFF switch of the dash panel gauge.)
15. Your Onboard Air Hookup Kit installation is now complete. Run the compressor to build up
pressure in the air tank. Once air pressure reaches the preset cut out pressure, the compressor
will shut off. Inspect all air line connections for leaks with soap and water solution. If a leak is
detected, the air line may not be cut squarely or pushed all the way in.
Fix connections as needed.
OPERATING INSTRUCTIONS:
1. Your Onboard Air Hookup Kit is designed for use in conjunction with an air tank. Make sure that
your air tank is rated for at least 150 PSI maximum working pressure, and that your air tank
setup is equipped with drain cock and pressure relief safety valve.
2. Your Dash Panel Gauge comes with ON/OFF power switch. This convenient feature allows you
to shut off power to air compressor when air compressor operation is not required. When
constant supply of compressed air is required, simply turn the ON/OFF switch to the ON
position, and when pressure in your air tank reaches pre-set cut-out pressure, the pressure
switch will shut off your air compressor automatically. When pressure in your air tank drops
below cut-in pressure, the pressure switch will automatically start air compressor.
3. Your Dash Panel Gauge is rated for maximum 150 PSI, do not use gauge on systems with
pressure ratings higher than 150 PSI.
