Preparing for Maintenance or Service

When preparing for maintenance or
service, take the following steps to ensure
maximum safety of service personnel:
• Disconnect and lockout the main power
switch and hang a sign at the switch of
the unit being serviced.
• 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.
• 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.
30
Relieve compressor and system air
pressure by opening the appropriate
manual relief valve prior to servicing.
Failure to relieve all system pressure
could result in death or serious injury
and property damage.
• (Water-cooled units) - Shut off water
and depressurize system.
Never assume the compressor is ready
for maintenance or service because it is
stopped. The automatic start feature
may start the compressor at any time.
Death or serious injury could result.
