Chapter 3 — Pump Removal and Replacement
The procedure for removing and replacing the pump is different for D-Series, W-Series and IH
stations. Refer to the following instructions for each model.
D-Series Stations
1. Open the alarm panel and shut off all power to the pump and the 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. Use the core wrench to close the stainless steel ball valve. Insert the bent end of the
core wrench into the hole on the handle of the valve and push down until the handle
is horizontal.
5. Use the core wrench to turn the bolt in the middle of the top housing 1/3 turn
counterclockwise to release the holding tabs.

pump weighs approximately 120 lbs. Note: DO NOT pull the pump out of the station
by the discharge tube, Equalizer tube or power cable.
7. Lower the new pump into the tank.
