2. Clean the Rotary Vane Compressor
a) Remove the nozzle and air relief (see figure 5-6). If the nozzle stem
looks black, clean as shown on page 4-6 or replace the nozzle.
b) Disconnect the ignition module connector. Ensure that the
temperature sensor is disconnected as well.
c) Remove the air filter and blower (see figure 5-6).
d) Connect the power cable and remote on/off switch.
e) Turn on the switch. After 5 seconds, the motor should start to spin
and the switch should start to blink (The blink is due to the
temperature sensor disconnections. See page 4-31 for more
information.)
f) Using a non-flammable electrical contact cleaner or non-petroleum
based flushing solvent (DO NOT USE BRAKE CLEAN as it will damage
the compressor)), spray directly into intake of compressor. Spray the
cleaner and run the motor for at least 30 seconds to remove all of the
vane dust and cleaner.
