WFS 101545 Operations Manual
This procedure assumes it is performed immediately after
Section 3
and all other conditions
remain the same.
Fill all three chambers of the
reservoir to the top of the
spindle chamber.
Verify all four associated valves
with the process filter housings
(#3 & 4) are open.
2 In-Flow valves
2 Out-Flow Valves
Open the bypass valve. See
Figure C4-1
On the Alarms page turn the
second from the bottom slider switch
to “ON”.
NOTE. To prevent inadvertent pump stop, the bottom slider switch should remain
on until commissioning is complete.
Start Pump 2 Crack open air bleed valve on Housing 3. Air will start coming out.
Immediately close the valve as soon as water starts coming out. Repeat this
procedure for Housing 4.
Close the In-Flow and Out-Flow valves on Housing 4. It will be in stand-by
After stopping Pump 2 close the Bypass valve.
Open the Process Supply and Process Return valves
Start the Pump 2. Water will flow out to the process machine. Water from the
process machine should drain down into the Lift Station. When the water reaches a
certain level in the Lift Station reservoir it will pump it back through the Process
Return line.
The Process Circuit is ready to start operation on Filter Housing #3
CAUTION:
Maintain sufficient water level in the “CLEAN SIDE” reservoir until
equilibrium is reached. (Water is returning at the same rate it is being pumped out.)
5.
STARTING THE SPINDLE CIRCUIT.
Verify the water level in the spindle chamber of the reservoir is full.
Open the Spindle Supply and Spindle Return
Start Pump 3. Water should flow out to the spindle or drive motor coolant loop and
return to the spindle reservoir.
CAUTION:
Maintain sufficient water level in the “SPINDLE” reservoir until equilibrium is
reached. (Water is returning at the same rate it is being pumped out.)
6.
STARTING THE CHILLER
With both Pump 1 and Pump 3 running the Chiller can be Enabled. It will automatically cycle
to keep each zone at the selected set-point See Sect 5.e.iii
