WFS 101545 Operations Manual
Lift Station is installed and proper facility power is on.
NOTE: The lift station will not run until a certain water level in the holding tank is reached. It will
cycle on and off when a constant flow of water is supplied.
All plumbing lines are connected to the process machine to permit process cooling
water to gravity drain and collect in the lift station. The lift station discharge is
connected to the Process Water Return connection.
Valving on the machine will permit the spindle water to return back to the WFS.
Facility water supply is open to the Water Make-Up lines.
All Air Bleed Valves are closed.
Verify that the proper three (3) phase electrical power with ground is connected.
WARNING!
To be performed by qualified personnel only.

FILLING THE RESERVOIR
Obtaining and maintaining the proper operating level in all of the reservoir chambers is an
iterative process. It requires starting and stopping pumps until all components in the system
are fill with water, air has been blead from the filter housings and the system is at equilibrium.
The description herein assumes that the system is starting with all of the filter housings, chiller
chambers and process lines empty.
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.
CAUTION:
The pumps can pull water from the reservoir much faster than the make-up lines can
restore. For that reason, the reservoir filling process requires careful observation until
equilibrium is achieved.
CAUTION:
If the water level in the reservoir is too low, air will be drawn into the pump inlet and
can cause damage.
If the water level in any chamber is less than 10 inches above bottom of the tank stop the
pumps until the chamber has been re-filled.
