Quincy Compressor-QSI
®
The following procedure should be followed for
maximum safety when preparing for maintenance or
service:
1) Disconnect and lockout the main power switch and
hang a sign at the switch of the unit being serviced.
2) Close shut-off valve (block valve) between receiver
and plant air system to prevent any back-up 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.
4) Shut off water and depressurize system if water-
cooled.
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.
