5.4 MAINTENANCE AND INSPECTION

5.4.1 Air supply style "A"

To close the air supply:
This procedure requires turning OFF the air compressor's
AC power by switching off the compressor isolating
switch (E15) located within the unit before servicing (see
figure 4.4).
Note: The air compressor motor is equipped with thermal
protectors that reset automatically.
protectors will stop the motor in case it overheats and
can automatically start the motor when they reset.
Compressor's air inlet filter:
Intake filters are standard on most compressors and will
provide adequate filtration for most applications.
filters periodically and replace when necessary.
inspection is suggested at 500 hours, and then the user
should determine the frequency. Most problems can be
prevented by keeping filters clean. Dirty filters decrease
compressor performance and can decrease compressor
service life.
Maintain a clean air filter cartridge to insure best flow and
performance. The location and the quality of the air being
ingested indicate the frequency for inspection and
replacement. A dirty filter restricts air flow, causes the
pump to run hotter and results in longer operating cycles.

To drain the air supply accumulator (E13):
The amount of moisture pumped into the system and
how quickly it accumulates is proportional to the amount
of humidity in the air and how long the compressor is in
operation.
At least once a year, open air inlet drain valve (E12)
until all condensate water is drained from the air
receiver. Close air option drain valve.
WARNING The relief valve and outlet pipe of the air
compressor may become very hot during normal
operation. Do not touch the valve, compressor heads or
outlet piping until the compressor has been turned off and
allowed to cool.

WARNING Do not unscrew relief valve head entirely off
