REPLACING THE PRIMARY PUMP
Before you begin this process, you will need a
new primary pump. You may also want to change
the check valves at this time. The check valves
have a 1½” MPT on one end, and a 1½” SLIP on
the other end. See page 15 for part numbers. You
will also need two (2) new wire ties.
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.
YOU WILL BE DISCONNECTING ALL THE
WIRES. BE SURE THEY DO NOT FALL INTO
THE SUMP PIT.
1. Unplug the primary pump, and its blue
piggyback controller from the wall outlet.
Unplug the charger for the backup pump
control unit, too.
2. Unplug the backup
pump from the back
of the black 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; 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. Lift the pump assembly out of the pit by the
handle on the primary pump. Tip the
assembly over the sump pit to drain any
remaining water.
7. Unscrew the no-hub connector on the pipe
connected to the primary pump.
8. Lay the pumps down and remove the three (3)
screws holding the primary pump to the sump
foot. Save these screws or replace them with
#14 x ¾” self-tapping stainless steel screws.
9. Ease the pump out of the no-hub connector.
10. 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.
11. Unscrew the pipe and the adapter from the
primary pump, and screw it on to the new
pump.
12. (OPTIONAL) 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.
(a)
Unscrew the check valve on the primary
pump and screw in a new one. (b) To replace
the other check valve, remove the other no-
hub connector and the float switch and ease
the Y-assembly off of the pipe. Unscrew the
old check valve and screw in the new valve.
