INSTRUCTIONAL PROCEDURES
C. Engage hydraulic system. A direction of rotation arrow is attached to the compressor pack-
age above the hydraulic coupling. The coupling/hub must be rotating in the direction the
arrow is pointing. If for any reason this arrow has been removed the correct compressor
rotation is clockwise when looking directly at the compressor shaft. Check the direction of
rotation by quickly engaging and then disengaging the compressor.
DO NOT RUN THE COMPRESSOR IN A REVERSE ROTATION FOR PERIODS LONGER
THAN 5 SECONDS. CONTINUED OPERATION IN THIS MANNER WILL RESULT IN
The safety shutdown switch should be wired in series with the solenoid that opens the flow of
the hydraulic oil to the compressor drive motor. In cases of high temperature and/or pressure,
the closing of the valve will stop the compressor operation.
Safety circuit testing for INFINITY
Safety circuit testing can be done in the following manner. Start the truck. Engage the com-
pressor. Take a screwdriver and touch the 1/16" allen head screw on the face of the tempera-
ture gauge and simultaneously touch the outside ring on the face of the gauge. This should shut
off the power to the solenoid of the hydraulics. Push the button in on the shutdown switch to
reset. Repeat the test with the pressure gauge if solenoid does not stop flow to compressor,
check wiring.
CAUTION
EXTENSIVE COMPRESSOR UNIT DAMAGE.
