Installation & Operation
Installation of Wiring
This unit is shipped from the factory with all
necessary internal wiring installed. The only
remaining wiring necessary is the wiring needed to
interface your vehicle/power source with the Boss
compressor. The unit is shipped with 1 end of a 5 pin
connector. They need to be connected as follows:
Pin A (Yellow) - 12VDC power supply
(24VDC if equipped)
Pin B (Red) - Battery (Positive Terminal)
Pin C (Green) - PTO Ground
Pin D(Orange) - 12VDC output signal
(24VDC if equipped)
Pin E (Black) - Battery (Negative Terminal)
Connecting the Hydraulic Hoses
The hydraulic hoses to the compressor should be
connected directly to the hydraulic manifold with
appropriately sized fittings. The input line should be
made from a good quality high pressure (min. 3000
PSI) hydraulic hose 1/2" or 3/4" i.d. The return line
can be made from a medium pressure (min 1000 psi)
hydraulic hose 3/4" i.d. Care should be taken to see
that the hoses are not installed with kinks or bends
that inhibit flow of the hydraulic oil. Lack of flow
could result in damage to the motor and compressor.
Lastly, check to make sure hoses are not in contact
with sharp objects or edges that may fray, chafe, or
cut them over time. Secure all hoses with tie down
straps or clamps.
Connecting the Air Hoses
The air discharge hose should be connected directly
to the "AIR" port. The fitting is a 1/2" female NPT.
The air line should be made from a good quality (min
200 Psi) hydraulic hose 1/2" or 3/4" i.d. Care should
be taken to see that the hose is not installed with
kinks. When adding an air hose, ensure OSHA
Regulation 1910.169 is followed.
