Installation / Operation
Installation
About 8"
1. This unit can be installed in sump pit with minimum
diameter of 12"(30cm) and depth of 12" (30cm).
Sump pit may be constructed of tile, concrete,
steel or plastic. Check local codes for approved
materials.
2. Install pump on solid, level foundation, as near as
possible to center of sump pit. Do not hang pump
from discharge pipe or power cord.
Pump must be level (column must be
vertical) when operating. If motor is tilted, internal
start/run switch may overheat and damage motor.
3. Pump should not be installed on clay, earth or
sand surfaces. Clean sump pit of small stones and
gravel which could clog the pump. Keep pump inlet
screen clear.
4. Thread discharge pipe into pump body carefully to
avoid stripping or crossing threads.
NOTICE Do not use ordinary pipe joint compound
on plastic pipe or pump. Pipe joint compound can
attack plastics and damage pump.
5. To reduce motor noise and vibrations, a short
length of rubber hose (1-5/8"(41mm) I.D., e.g.
radiator hose) can be connected into discharge line
near pump using suitable clamps.
Risk of electric shock. Can shock,
burn or kill. Pump is designed for 115V, 60 HZ
operation and requires an individual branch circuit
of 15 amperes capacity. It is supplied with a 3-wire
cord set with grounding-type plug for use in a
3-wire, grounded outlet. Do not cut off the round
grounding prong. For safety, outlet must always
be electrically grounded to a suitable electrical
ground such as a grounded water pipe or a properly
grounded metallic raceway or ground wire system.
6. Locate Float Rod Guide (Key No. 7) about 6" (16cm)
below motor. Clamp guide to column with screw
provided.
Risk of flooding. Be sure that guide is
securely clamped so that float rod is vertical and can
move up and down freely. If float is angled or binds,
pump may not start, allowing flooding to occur.

7. Screw float onto threaded end of rod. Threads on rod
will cut threads into corrosion resistant float.
8. Insert plain end of float rod up through eye of rod
guide.
9. Slide one rod stop on float rod before passing rod
through eye of pump switch. Slide 2nd rod stop on
rod after passing through eye of switch. Position
2nd rod stop flush with top of rod.
10. Position lower rod stop to within 8"(20cm) of switch
lever arm. With lower rod stop in this position,
pump will automatically cycle at approximately
2-1/2"(6cm) off and 10-12"(25-30cm) on. For faster
cycling, move lower rod stop closer to switch lever
arm.
11. If pump discharge line is exposed to outside
subfreezing atmosphere, then portion of line
exposed must be installed so any water remaining
in pipe will drain to outfall by gravity. Failure to do
this can cause water trapped in discharge to freeze
which could result in damage to pump.
12. Install an in-line check valve to prevent flow
backwards through pump after pump shuts off.
NOTICE If using a check valve without an air bleed
hole, drill a 1/8" (3.2mm) hole in discharge pipe just
above pump body but below the check valve to
prevent air locks.
13. After all piping and controls have been installed,
unit is ready for operation.
14. Run pump through one cycle to check float switch
operation.
Risk of sudden starts. Can cause
electrical shock and personal injury. The pump
motor is equipped with automatic resetting
thermal protector and may restart unexpectedly.
Protector tripping is an indication of motor
overloading as a result of operating pump at low
heads (low discharge restriction), excessively high
or low voltage, inadequate wiring, incorrect motor
connections, or a defective motor.
Operation
Risk of electric shock. Can shock, burn
or kill. Do not touch sump pump, pump motor, water, or
discharge piping when pump is connected to electrical power.
Always disconnect pump cord (power) before handling.
1. Plug this unit into a 115V outlet, on an individual
branch circuit, with a Class A, 15 amp GFCI (Ground
Fault Circuit Interrupter).
Consult your local electrician for information and
availability.
2. Fill sump pit with water, pump will start
automatically when lower rod stop actuates switch
lever arm. When upper rod stop actuates switch
lever arm, pump will stop.
NOTICE Do not allow pump to run dry.
Risk of electric shock. Can shock,
burn or kill.Before attempting to service, always
disconnect power from unit.
3. The motor is equipped with an automatic reset
thermal protector to protect unit from overheating.
When motor has cooled sufficiently, switch will reset
automatically and restart motor. Repeated tripping
could be caused by low voltage, long extension cords,
clogged impeller, very low head or lift. Cycling of
protector will cause eventual motor burnout.
