Section V - Servicing
Fluid Filter
The fluid filter is a
spin on, full flow unit.
Replacement of the filter
requires spinning off the
cartridge and replacing
it with a new one.
The initial filter change
should occur after the
first 500 hours of operation. During normal
service, the filter cartridge should be
replaced under the following conditions,
whichever occurs first:
•
every 1,000 hours
•
every fluid change
Replacing the fluid filter:
• Turn the compressor off by the main
switch and perform proper lockout/
tagout procedure.
Compressor Fluid
The interval for changing the compressor
fluid depends on the type of fluid used and
the operating conditions of the unit. See
Section VI - Compressor Fluids for more
specific information concerning fluid life of
specific fluids.
Fluid change instructions:
• Turn the compressor off by the main
switch and perform proper lockout/
tagout procedure.
• Completely depressurize the
compressor circuits (reference
‘Preparing for Maintenance or Service’
on page 28 and ‘Safety’ instructions on
page 30).
• Slowly unscrew the plugs at the fluid fill
and discharge port.
• Attach a pipe to the drain valve, open
the drain valve and allow all the fluid
to drain from the unit. In order for all
fluid to be removed, fluid should be at
running temperature (between 140°F
and 175°F).
• Dispose of the fluid in accordance with
Local, State, and Federal environmental
regulations.
• Remove the pipe, close the draincock
and reinstall the plug.
• Fill the compressor with the appropriate
amount of new fluid through the fluid
inlet port.
• Check the fluid level at the sightglass.
• Replace the o-ring on the fluid filler cap
and reinstall.
• Completely depressurize the
compressor circuits (reference
‘Preparing for Maintenance or Service’
on page 28 and ‘Safety’ instructions on
page 30).
• Using a suitable band spanner, unscrew
and remove the fluid filter.
• Lubricate the new filter gasket and
install the filter.
Notice!
Use genuine Quincy replacement
filters only.
• Tighten using the band spanner.
• Dispose of the used fluid filter cartridge
in accordance with Local, State, and
Federal environmental regulations.
