Section V– Servicing
Preparing for Maintenance or Service
! WARNING !
Never assume the compressor is ready for maintenance or service because
it is stopped. The automatic control may start the compressor at any time.
Death or serious injury may result.
The following procedure should be used 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
airflow 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.
NOTE:
Only trained and qualified technicians should perform maintenance.
