Pump Removal and Replacement 3–2
W-Series and Upgrade Stations
1. Open the alarm panel and shut off all power going to the pump and alarm system.
2. Remove the station lid.
3. Disconnect the EQD. If the tray cable side of the EQD is wet or shows evidence of
moisture, the EQD insert must be replaced. Determine the source of the moisture
and correct the problem before connecting a new pump to the EQD.
4. If the unit is equipped with a slide face valve, close the discharge by lifting up on the
handle. Pull the slide face with the discharge hose connected to the pump out of the
discharge assembly; use a long piece of PVC pipe with a 1-inch female threaded
coupling on the end.
If the unit is equipped with a ball valve, close the valve and loosen the compression
nut on the discharge hose.
5. Use the yellow ropes attached to the pump to pull the pump out of the station; the
pump weighs approximately 120 lbs. Note: DO NOT pull the pump out of the station
by the discharge tube, Equalizer tube or power cable.
6. Lower the new pump into the tank.
7. Connect the discharge hose to the valve and open the valve.
8. Perform start-up procedures as described in Chapter 4 — Start-Up Procedure.
