Preparing for Maintenance or Service
The following procedure should be
followed for maximum safety when
preparing for maintenance or service:
) Disconnect and lockout the main
power switch and hang a sign at the
switch of the unit being serviced.
2) Close shutoff valve (block valve)
between receiver and plant air system
to prevent any backup of air flow
into the area to be serviced. NEVER
depend upon a check valve to isolate
the system.
3) Open the manual vent valve and wait
for the pressure in the system to be
completely relieved before starting
service. DO NOT close the manual
vent valve at any time while servicing.
Warning!
Never assume the compressor is ready
for maintenance or service because it
is stopped. The automatic dual control
may start the compressor at any time.
Death or serious injury could result.
Safety
notiCe!
Maintenance should be performed by
trained and qualified technicians only.
Safety procedures while servicing the
compressor are important to both the
service personnel and to those who may
be around the compressor and the system
it serves. Listed below are some, but not
all, procedures that should be followed:
•
Wait for the unit to cool before
starting service. Temperatures may
exceed 80°F when the compressor is
operating.
•
Clean up fluid spills immediately to
prevent slipping.
•
Loosen, but do not remove, flange or
component bolts. Carefully pry apart
to be sure there is no residual pressure
before removing bolts.
•
Never use a flammable solvent such as
gasoline or kerosene for cleaning air
filters or compressor parts.
•
Safety solvents are available and should
be used in accordance with their
instructions.
Caution!
Unusual noise or vibration indicates
a problem. Do not operate the
compressor until the source has been
identified and corrected.
