Before accessing live electrical parts, disconnect the power supply to the
dryer using disconnect switch or disconnect the cable connections.
Preventive maintenance
For optimum performance from your dryer, follow the periodic
maintenance schedule described below.
WEEKLY
CONDENSATE DRAINS
Verify that the condensate drains
are operating correctly.
MONTHLY
COMPRESSOR
Make sure the refrigerant
compressor temperature is below
140 F (60 C) when running.
EVERY 4 MONTHS
CONDENSER
Remove any dust from the
condenser fins.
COMPRESSOR
Make sure compressor power
consumption complies with data
plate specifications.
YEARLY
CONDENSATE DRAINS
Completely disassemble the
drains and clean all their
components.
AIR FILTER
Replace air filter element.
MOISTURE SEPARATOR MAINTENANCE
The moisture separator will operate indefinitely under normal working
conditions, however at some time it may be necessary to replace the
seals should the housing leak.
1. Isolate the housing from the air supply.
2. Fully depressurize in drain bowl as appropriate.
3. Unscrew bowl and remove. If pressure has not been completely
released from the housing, air will escape from the warning hole giving
an audible alarm. Screw back bowl and repeat instruction 2 before
attempting again. Should resistance to unscrewing be experienced,
provision is made for a ’C’ spanner to fit onto the ribs of the bowl.
4. Check condition of bowl seal and replace if necessary. Clean screw
threads.
5. The autodrain assembly is not serviceable and must be replaced if
faulty.
6. Refit bowl with ’O’ ring seal.
7. Repressurize and check for leaks. If leaks occur they will most
probably be from the bowl ’O’ ring. Depressurize housing and remove ’O’
ring as stated above and inspect and clean. Ensure that mating surfaces
are clean and then refit ’O’ ring and repressurize.
Auto – drain assembly
