WFS 1545 Operations Manual
X.
Stop the pump if the water drops to 5 inches (130 mm) from the bottom. Allow reservoir
chamber to re- fill. Do not re-start the pump until reservoir reaches the fill line.
XI.
With pump # 1 running start pump # 2. Stop both pumps if the water drops to 5 inches
(130 mm) from the bottom of the reservoir in either chamber. Allow reservoir chamber to
re- fill. Do not re-start the pumps until reservoir reaches the fill line.
XII.
Repeat process
ix-xi.
Water will eventually begin to fill the Lift Station reservoir and be
returned to the Dirty Side.
XIII.
Monitor the water level for several minutes with both pumps running.
XIV.
After several minutes of operation bleed air from the final filters. Carefully open up the
air-bleed valves one at a time starting at the filter housing closest to the reservoir. Close
the valve as soon as water begins to squirt out. This may happen right away.
WARNING !
: Water from the air bleed valves may come out at high velocity. Keep personnel from their
opening. If sensitive equipment is in the vicinity attach appropriate fittings and hose to direct water to safe
container.
5.
STARTING THE CHILLER
The chiller provides cooling by refrigeration for the process water. The temperature is controlled by
a RANCO Electronic Temperature Controller mounted on the front of the WFS to the side of the
control cabinet.
To avoid icing up internal components do not run the chiller unless Pump 1 is running.
The chiller is controlled by the corresponding On –Off push buttons. The cooling fan will start up
immediately and the RANCO controller will illuminate and display current settings. After a few
seconds the condensing pump will start up and start cooling water for the Process loop.
CAUTION
:
To avoid ice damage do not operate the chiller unless the Internal Circulating Pump is running.
6.
RELIEF VALVE PRESSURE SETTING
The relief valve limits the maximum system pressure is preset to 75 PSI
prior to shipment. This valve is factory set. But it can be field adjusted if
required. Turn knob clockwise to increase pressure and counter-
clockwise to decrease pressure.
Remove plug and install
pressure gage to check
relief valve setting.
