Procedure
The air filter auto drain requires periodic
cleaning to maintain maximum filtering efficiency
and to avoid excessive pressure drop.
The cleaner the compressed air supply, the less
maintenance will be required. A visible coating
of dirt or condensate on the filter element surface
or excessive pressure drop is an indication that
cleaning is necessary.
WARNING
Before disassembling the air
filter/auto drain, turn off the
air supply and depressurize
the system and filter.
Required Tools
compressed air, mild detergent
solution, alcohol
Perform only when the unit is OFF
with power disconnected and COOL.
Turn off the compressed air supply and
depressurize the unit.
Turn power OFF at the main disconnect
switch.
