Before doing compressor maintenance, discon-
nect compressor from power source and lock out
power source. Isolate compressor from line pres-
sure by closing recommended discharge shut--
off valve and releasing all internal pressure from
compressor.
ELEMENT INSPECTION
1. Place a bright light inside the element to inspect
for damage or leak holes. Concentrated light will
shine through the element and locate any holes.
2. Inspect all gaskets and gasket contact surfaces
of the housing. Should faulty gaskets be evident,
correct the condition immediately.
3. If the clean element is to be stored for later use, it
must be stored in a clean container.
4. After the element has been installed, inspect and
tighten (if necessary) all air inlet connections
prior to resuming operation.
