REPLACING THE BACKUP PUMP

Before you begin this process, you will need a

new backup pump, new check valves, and new

wire ties. The check valves have a 1½” MPT on

one end, and a 1½” SLIP on the other end. See

page 15 for part numbers.

Risk of electrical shock or battery explosion,

which can cause serious injury or death. Wear

eye protection. Work in a well-ventilated

area. DO NOT smoke or allow a spark or flame

in the vicinity of the battery. Avoid dropping

metal tools on the battery. Review the safety

instructions on page 1.

1. Unplug the primary pump, the blue controller,

and the power cord for the backup pump

control unit from the wall outlet.

2. Unplug the backup pump from the back of the

gray control unit.

3. Remove the cover of the battery box and fan

the area around the top of the battery with a

piece of cardboard (or another non-metallic

material) to remove any hydrogen or oxygen

gas that may have been emitted from the

battery

4. Remove the sensor from the battery, and

remove the battery wires from the battery

terminals. Be sure they DO NOT touch each

other while one is connected to the battery.

5. Slowly

loosen the rubber union on the top of

the combination pump assembly to separate

the pipes. The water trapped in the pipe will

pour out into the sump as the rubber union is

loosened.

6. Separate the pump assembly from the rubber

union and lift it out of the sump pit by the

handle on the primary pump. Tip the

assembly over the sump pit to drain away any

remaining water.

7. Lay the pumps down and remove the two (2)

screws holding the backup pump.

8. Loosen the hose clamp holding the float

switch, cut the wire tie holding the switch,

and remove the switch from the pipe. Note its

position.

9. Loosen the hose clamps on the no-hub

connectors on both pumps.

10. Ease the Y-assembly off of the pumps.

11. Unscrew the pipe adapter from the backup

pump.

12. While you have the pump apart, this would

be a good time to replace the check valves.

A check valve with 1½” MPT on one end, and

1½” SLIP on the other is commonly

available, or you may order this part

#1141001 from Glentronics.

13. Now, reverse the process. Replace the pump

by first screwing the adapter assembly into

the new pump.

14. Then screw the pump to the pump stand.

15. Ease the Y-assembly back onto the check

valves, and tighten the hose clamps.

16. Install the backup pump float switch on the

check valve with the hose clamp, and secure

the cage to the discharge pipe with a wire

tie. Make sure the floats are vertical.

17. Lower the pumps into the sump pit by the

handle on the primary pump.

18. Ease the Y-assembly back into the rubber

union on the discharge pipe and tighten the

hose clamps.

DANGER

YOU WILL BE DISCONNECTING ALL THE

WIRES. BE SURE THEY DO NOT FALL INTO THE
