WARNING
Physical harm may occur if human body parts are in contact or exposed to
the process vacuum. Assure that all connections are protected from human
contact.
WARNING
If rated vacuum or pressure levels are exceeded, process uids will migrate
to other parts of the booster and system.
CAUTION
Do not touch hot surfaces.
The upper limit of the booster operation is 375º F (190º C). Do not touch
the booster while it is in operation and assure booster is cool when not in
operation.
CAUTION
Use of a thermowell insulates the thermocouple. Invalid and delayed
readings will result. This can result in ineffective protection devices.
NOTE
The upper limits are not intended for continuous operation. Consult with
factory for detailed information assistance.
6.5 STOPPING
CAUTION
Venting the booster to pressures above cut-in while running can damage
the pump.
Stop the booster by turning off the motor. Isolate the booster from the vacuum system and vent the booster
to atmosphere. Turn off the cooling water if water cooled. Stop the backing pump. Refer to component
instruction manual.
6.6 STOPPING
CAUTION
Venting the booster to pressures above cut-in while running can damage
the pump.
Stop the booster by turning off the motor. Isolate the booster from the vacuum system and vent the booster
to atmosphere. Turn off the cooling water if water cooled. Stop the backing pump. Refer to component
instruction manual.
6.7 WATER INJECTED VACUUM BOOSTERS
Water injected into the inlet of a booster operating on vacuum service will cool the booster. The water
absorbs the heat of compression as it passes through the unit along with the air/gas being compressed.
A booster cooled in this manner can operate safely at higher vacuums or higher inlet temperatures than a
normally uncooled unit.
