YEARLY
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.
