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.
EVERY 4 MONTHS CONDENSER
Remove any dust from the con-
denser ns.
COMPRESSOR
Make sure compressor power
consumption complies with data
plate specications.
YEARLY CONDENSATE DRAINS
Completely disassemble the
drains and clean all their compo-
nents.
AIR FILTER
Replace air lter element.
MOISTURE SEPARATOR MAINTENANCE
The moisture separator will operate indenitely under
normal working conditions, however at some time
it may be necessary to replace the seals should the
housing leak.
Isolate the housing from the air supply.
Fully depressurize in drain bowl as appropriate.
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 t onto the
ribs of the bowl.
Check condition of bowl seal and replace if
necessary. Clean screw threads.
Ret bowl with ’O’ ring seal.
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 ret ’O’ ring
and repressurize.
