WARNING:
Before operating the pump, be sure to check
the motor rotation. Damage can result from
running the pump backwards.
When viewing the motor from the motor
fan housing end, the rotation should be
counterclockwise. If the motor is clockwise,

rotation by switching two of the leads.
Ensure that the emergency generation system
electrical supply is consistent with the vacuum
system's requirements.
The electrical controls for the system were wired
at the factory and were fully tested.
Three-phase power supplied from emergency
generator(s) must match that of the normal
supply to allow for correct direction of the motor
rotation at all times.

Intake Piping
Before connecting any piping, the plastic thread
protector installed in the connection port must be
removed. We recommend that the main vacuum
line to the receiver should not be reduced below
that provided on the receiver. Smaller lines will
result in lower pumping speeds than the rated
values. Long piping runs may need to be increased
in size to minimize pressure drop. Improper line
sizing may result in a loss of capacity. Ideally,
piping should be constructed using long radius
elbows and a minimum number of turns to keep
piping as short as possible to minimize pressure
drop between the system and end point of use.
All secondary lines should be taken from the
top or side of the main line to prevent any
