MAINTENANCE
The
air filters
should be changed periodically depending upon the cleanliness of the
air coming from the compressor. Both
air filters
have an
automatic drain valve
that
drains the filter bowl of water. The valves function satisfactorily as long as the air is
not very oily. Both bowls should be checked for a buildup of emulsified (white solid)
oil and water. This build-up will clog the valve.
If the valves become clogged, oil and water can be sent into the pneumatic circuitry.
This will not harm the
DDP
if it is detected within a few days. The passage of oil and
water into the
DDP's
air side will show up in the air exhaust muffler. Oil and water
droplets and perhaps a pool of liquid under the
DDP
will appear.
