WFS 1545 Operations Manual
VIII.
Repeat process until the water level in the clean side begins to cascade over the internal
weir. The make-up valve will be able to compensate for any minor losses due to leakage or
evaporation.
IX.
With Pump one running and water cascading from the Clean Side over the weir to the Dirty
Side 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.

PROCESS SUPPLY CIRCUIT
This procedure will fill the final filters, all plumbing lines to and from the process equipment and
the lift station reservoir. It requires that the Lift Station is properly installed and powered.
NOTE: The Lift Station has a small internal reservoir with a float switch and will not cycle on until the water
level in the internal reservoir reaches a certain level. The Lift Station will tend to cycle on and off.
NOTE: The filling process will require many pump starts and stops to reach equilibrium.
CAUTION:
Use caution to avoid allowing water level to sink too low. Stop pump if there is any indication that
air is getting into the pump inlet.
I.
Complete procedure outlined in section
2.a
.
II.
Close Air Bleed valves on top of filter housings
III.
Open all three facility interface ball valves.
IV.
Verify there is facility water available for make-up.
V.
Remove reservoir cover so water level can be observed.
VI.
Verify that both chambers of the reservoir are filled to the
proper level
VII.
Turn Power Selector Switch to “ON” position
VIII.
Press Reset Push Button. Blue Control Power indicating light
should come on.
IX.
Depress Pump 1 start button and observe the water in the chamber. Water should be
circulating over the internal weir. The system should be in equilibrium.
