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
#1141003 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 float switch on the check valve or
on the no hub coupling with the hose clamp,
and secure the cage to the discharge pipe
with a wire tie. Make sure the floats are
vertical and the bottom of the backup float
is higher than the bottom of the primary
float switch.
17. Lower the pumps into the sump pit by the
handle on the primary pump.
! DANGER
YOU WILL BE DISCONNECTING ALL THE
WIRES. BE SURE THEY DO NOT FALL INTO THE
SUMP PIT.
