WFS 1545 Operations Manual
The power wires attach to the three lugs provided on the top of the distribution bus bar. The
ground wire must be attached to the grounding terminal to the left of the bus bar. See Figure 8.

PLUMBING CONNECTIONS
There are three (3) facility plumbing connections to the WFS Unit.
•
Make-up Water 1” NPT
•
Process Cooling Supply 1” NPT
•
Process Cooling Return 1-1/4” NPT
The connection for the Process Cooling Supply is 1” NPT. This provides
water filtered and cooled by refrigeration to cool the cutting, grinding
or dicing process. This process is normally “open-loop”. Therefore,
a separate “Lift Station” is required to return the water back to
the WFS. The customer is responsible to collect and direct the
process water to the lift station pump.
The connection for the Process Cooling Return is 1-1/4” NPT. This
connection directs return water from the Lift Station back to the
reservoir.
The connection for the Make-Up Water is 1” NPT. The water source can
be provided from clean ordinary tap water.
i.
LIFT STATION INSTALLATION
The inlet to the Lift Station (LS) is gravity fed from used process water and therefore must be
mounted at a lower elevation than the process water collection point
The LS has two available inlet ports: one on top and the other on the side. Either can be used
and the unused one plugged. The port is a 2” NPT.
A True Union check valve is provided with the LS. This should be installed on the discharge line
as close to the unit as possible. The check valve arrow should be pointing up.
NOTE:
Leave enough wire in the event that two legs
need to be switched. If motor rotation is in wrong
direction switch wires here or at source.
DO NOT
switch leads after the circuit breakers
