Installation
INSTALLATION
1. Install the pump in a sump pit with a minimum diam-
eter of 12" (305mm) for models equipped with verti-
cal switches and 15" (381mm) for tethered float
switch models. The sump depth should be 18" mini-
mum (467mm). Construct the sump pit of tile, con-
crete, steel or plastic. Check the local codes for
approved materials.
2. The pump should not be installed on clay, earth or
sand surfaces. Clean the sump pit of small stones and
gravel which could clog the pump. Keep the pump
inlet screen clear.
3. Install the pump in the pit so that the switch operat-
ing mechanism has maximum possible clearance.
4. Install the discharge plumbing. The discharge pipe diam-
eter should be at least as large as the discharge port or
discharge adapter diameter. See the "Specifications"
section on Page 2. When using rigid pipe, use plastic
pipe. Wrap the threads with Teflon tape
pipe into the pump hand tight +1 – 1-1/2 turns.
NOTICE: Do not use ordinary pipe joint compound
on plastic pipe. Pipe joint compound can attack plas-
tics and damage the pump.
Risk of flooding. If a flexible discharge
hose is used, make sure the pump is secure in the
sump to prevent movement. Failure to secure the
pump may allow pump movement, switch interfer-
ence and prevent the pump from starting or stopping.
5. To reduce motor noise and vibrations, a short length
of rubber hose (e.g. radiator hose) can be connected
into the discharge line near the pump using suitable
clamps.
6. Install an in-line check valve to prevent backward
flow through the pump when the pump shuts off.

7. Power Supply: The pump is designed for 115 V., 60
Hz., operation and requires a minimum 15 amp indi-
vidual branch circuit (refer to Motor, Switch and Cord
Specifications chart, Page 3). Both the pump and
switch are supplied with 3-wire cord sets with
grounding-type plugs. The switch plug is inserted
directly into the outlet and the pump plug inserts into
the opposite end of the switch plug.
kill. The pump should always be electrically ground-
ed to a suitable electrical ground such as a grounded
water pipe or a properly grounded metallic raceway,
or ground wire system. Do not modify the cord or
plug or cut off the round ground pin.
8. If the pump discharge line is exposed to an outside
sub-freezing atmosphere, the portion of the line
exposed must be installed so any water remaining in
the pipe will drain to the outfall by gravity. Failure to
do this can cause the water trapped in the discharge

to freeze which could result in damage to the pump.
9. After the piping and check valve have been installed,
the unit is ready for operation.
10. Check the operation by filling the sump with water
and observing pump operation through one complete
cycle.
operational check may lead to improper operation,
premature failure, and flooding.
