PREPARING FOR MAINTENANCE OR SERVICE
! WARNING
Never assume the vacuum pump is ready for maintenance or service because it is
stopped. The automatic control could start the vacuum pump 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 tag the switch of the unit being serviced.
2. Close shut-off valve (block valve) between receiver and plant vacuum system to prevent any back up of vacuum
pressure in the vacuum pump area to be serviced.
NOTE:
Never depend on a check valve to isolate the system.
3. Open the manual vent valve and wait for the vacuum in the system to be completely relieved before starting
service.
4. Shut off water and pressurization system (if water-cooled).
