WFS 101545 Operations Manual
NOTE: The chiller has a “Bump Start” design feature. This may cause the chiller to perform
three rapid Start-Stop sequences before commencing with normal operation. The chiller
also has built in delays that regulate how quickly the unit can recycle.

RESERVOIR PROCESSS FLOW
Durning normal operation, after equilibrium is established, the reservoir level is maintained
by two float valves. These can compensate for evaporation and minor losses due to
splashing during process cooling.
To maintain proper filtration and cooling water should cascade from the Clean Side into the
Dirty Side.
8.
PRESSURE SETTINGS
The maximum pressures are limited by two relief valves. One valve limits the Process
Pressure and the other the Spindle Pressure. They are factory set at 75 PSI.
They can be field adjusted by turning the top knob in to increase and out to decrease
pressure. See Figure C8.1
WARNING
Do not adjust pressure above 100 PSI
CAUTION
Settings that are too low can cause excessive heat generation.
