[A CAUTION] Risk of pinching
hands
or fingers.
To avoid
a band injury from a collapse
of plumbing,
support the pipe
above the separation before cutting
or disassembly.
4. Lift the primary pump and discharge pipe assembly out
of the sump.
[AWARNINGIRLsk of electrical
shock.
Do not lift the
pump
by the electrical
cord; lift pump
only by the discharge
pipe, lifting ring or handle
on the pump.
Lifting by the cord
can damage
the cord.
NOTICE: The discharge
pipe is filled with water.
Drain the
water from the discharge
pipe assembly.
Keep the work area
dry.
Remove the
hose coupling
or mark the
1st cut here.--_
Support the
Pipe before
cutting.
5. Hold the coupling
(Key No. 6, Page 9) with
the channel
locks, insert the screwdriver
into the tee for leverage
and
tighten the tee with the screwdriver.
Finish with the tee
in a straight
up and down
(vertical)
position.
6. Clean the pipe ends with the cloth towel.
7. Glue the cut-off piece
of discharge
pipe
into the top of
the tee. If your pipe is 1-1/4", you will need
to glue the
reducer
bushings
into the tee and glue the pipe into the
bushings.
Place the assembly
on to the primary
discharge
pipe.
Do not glue the tee onto
the Primary Pump dis-
charge
pipe.
8.Mount
the float switch
assembly
(Key No. 9, Page
9)
loosely to the discharge
pipe with the cable ties (Key Nos.
9A & 9B, Page 9). Approximately
3 "(76ram) of cord length
should
be
left
between
the
float
and
the
clamp.
Adjustments
may be needed,
do not tighten the cable ties.

1.Make
a second
cut in the discharge
pipe
at the pencil
mark made in step 1 and set the cut-off piece of discharge
pipe aside. See Figure 2.
2. Wrap the threads
of the close nipple
(Key No. 5, Page 9)
counterclockwise
with
2 turns of teflon
tape and
set
aside.
NOTICE:
There
must
be a check
valve installed
in the
Primary
Sump Pump discharge
between
the tee and the
Primary Sump Pump. This will prevent
recirculation
into
the Primary
Pump when
the Back Up Sump Pump comes
on. See Figure
2.

Installation of Double Pump Assembly in
Sump Pit:
1. Put the double
pump
assembly
back into the sump pit.
NOTICE:
The discharge
pipe now overlaps
the discharge
pipe leading
outside.
2.Mark
the discharge
pipe where
it should
be cut. Be sure
to leave a 1/4" air gap between
the ends of the pipes. This
gap will absorb
noise from vibration
and allow for flexi-
I_flity. See Figure 4, Page 5.
