IMT CAS3560 Air Compressor Manual Part No. 99903566
Compressor Start-Up & Shut-Down
Compressor Start-Up
a
Make sure all guards, covers, and access plugs are in place and secured.
b
Start the vehicle engine.
c
Engage the PTO per the manufacturer's instructions.
d
Engage the compressor by turning on the power. The power switch location varies
depending on the installation. If the compressor is mounted on an IMT service truck with
a crane, the power switch is located on the crane remote. Otherwise, the power switch
may be located on the truck or as a custom wiring application.
WARNING
This compressor produces loud noise. Extended exposure to loud noise can cause hearing
loss. Wear hearing protection when operating.
Use the relay module to determine if the compressor is operating normally. The
enable
and
power
indicator lights will light. When the compressor oil temperature reaches 180° F, the
fan
indicator light will turn on, indicating that the fan is running. Once the fan starts to run, it will
"latch" on and continue to run until the compressor is turned off.
Do not run the compressor for less than 15-minute increments. Short run times will increase
water / moisture content in the compressor system. Water and moisture will adversely affect the
life of the compressor.
CAUTION
Operating this unit in excess of 8000 RPM will void the warranty and will shorten the normal
service life of the compressor.
Compressor Shut-Down
a
Turn off the compressor using the power switch.
b
Disengage the hydraulic pump / PTO.
c
Once the drive motor stops, the compressor will purge itself of air. This "blowdown cycle"
typically requires approximately 90 seconds. It will not purge the reservoir tank, but only
the compressor unit. During the blowdown cycle, the compressor will not restart if turned
on. If the power switch is turned on, the compressor will not restart until the blowdown
cycle is complete.
