minor personal injury or property damage if ignored.
The word NOTICE indicates special instructions which are
important but not related to hazards.
Electrically powered sump pumps normally give many years
of trouble-free service when correctly installed, maintained,
and used. However, unusual circumstances (interruption of
power to the pump, dirt/debris in the sump, flooding that
exceeds the pump’s capacity, electrical or mechanical failure
in the pump, etc.) may prevent your pump from functioning
normally. To prevent possible water damage due to flooding,
consult your dealer about installing a secondary sump
pump, a DC backup sump pump, and/or a high water alarm.
See the “Troubleshooting Chart” in this manual for information about common sump pump problems and remedies.
1. Know the pump application, limitations, and potential
hazards.
2. Disconnect power before servicing.
3. Release all pressure within system before servicing any

water recirculates.
PERFORMANCE
INSTALLATION
1. Install pump in sump pit with minimum diameter of 14"
(356mm). Sump depth should be 14" (356mm). Construct
sump pit of tile, concrete, steel or plastic. Check local codes
for approved materials.
2. Install pump in pit so that switch operating mechanism
has maximum possible clearance.
3. Pump should not be installed on clay, earth or sand surfaces. Clean sump pit of small stones and gravel which
could clog pump. Keep pump inlet screen clear.
NOTICE: Do not use ordinary pipe joint compound on
plastic pipe. Pipe joint compound can attack plastics.
4. Install discharge plumbing. When using rigid pipe, use
plastic pipe.
Slip rubber coupling over pump discharge. Install and
tighten first clamp. Place second clamp loosely over coupling. Slip coupling over discharge pipe. Clamp hose
tightly with second clamp.
NOTICE: Discharge piping should be as short as possible
to reduce pipe friction losses. Discharge
pipe diameter should be equal to or larger than discharge
size of pump. Smaller pipe diameters will restrict capacity of
pump and reduce performance. Do no use flexible discharge pipe in any permanent installation.
Risk of flooding. Failure to secure
pump may allow pump movement, switch interference and prevent pump from starting or stopping.
If a flexible discharge hose is used, make sure pump is
secured in sump to prevent movement.
5. To reduce motor noise and vibrations, a short length of
rubber hose (e.g. radiator hose) can be connected into
discharge line near pump using suitable clamps.
6. Pumps have an internal check valve to prevent flow backwards through pump when it is shut off.
7. Power Supply: Pump is designed for 115 V., 60 Hz., operation and requires a minimum 15 amp individual branch circuit. Both pump and switch are supplied with 3-wire cord
sets with grounding-type plugs. Switch plug is inserted
directly into outlet and pump plug inserts into opposite end
of switch plug.
Hazardous voltage. Pump should 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. Do not modify cord or plug or cut off round ground pin.
8. Secure discharge line before starting pump.
9. If pump discharge line is exposed to outside sub-freezing
atmosphere, portion of line exposed must be installed so
any water remaining in pipe will drain to the outfall by
gravity. Failure to do this can cause water trapped in discharge to freeze which could result in damage to pump.
10. After piping and check valve (if needed) have been
installed, unit is ready for operation.
11. Check operation by filling sump with water and observing
pump operation through one complete cycle.
Failure to make this operational check
may lead to flooding and premature failure.
NOTICE: This unit is not designed for applications involving salt
water or brine! Use with salt water or brine will void warranty.

ELECTRICAL
Hazardous Voltage. Can cause severe or
fatal electric shock. Pump is supplied with a grounding con-
ductor and ground ding-type attachment plug. To reduce risk
of electric shock, be certain that it is connected only to a
properly grounded, grounding type receptacle. Ground terminal on pump cord plug is provided for your protection. DO
NOT REMOVE!
A ground fault circuit interrupter is recommended for use with
any electrical appliance submerged in water. For installation
of such a circuit, consult a licensed electrician.
OPERATION / MAINTENANCE
Risk of electric shock. Before attempting to
check why unit has stopped operating, disconnect power
from unit. Do not handle pump with wet hands or when
standing on wet or damp surfaces, or in water.
Risk of flooding. If a flexible discharge hose
is used, pump may move when motor starts. If the switch hits
the side of the sump, the switch may stick and prevent the
pump from starting. Make sure the pump is secured so it
cannot move around in sump.
Risk of sudden starts. The pump motor is
equipped with automatic resetting thermal protector and
may restart unexpectedly.
1. If protector trips, motor may be overloading. Check for
the following problems:
A. Not enough back pressure in discharge pipe.
B. Voltage too high or too low.
C. Wires to motor too small.
D. Motor incorrectly connected to power supply wires.
E. Defective motor.
2. Shaft seal depends on water for lubrication and cooling.
Do not operate pump unless it is submerged in water as
seal may be damaged if allowed to run dry.
3. Motor is equipped with automatic reset thermal protector.
If temperature in motor should rise unduly, switch will cut
off all power before damage can be done to motor. When
motor has cooled sufficiently, switch will reset automatically and restart motor. If protector trips repeatedly,
unplug the pump and remove it; check for cause of difficulty. Low voltage, long extension cords, clogged
impeller, very low head or lift, etc., could cause cycling.
4. Pump will not remove all water. If manually operated
pump is operating and suddenly no water comes out discharge hose, shut off unit immediately. Water level is
probably very low and unit has broken prime.
CLEANING AND REPLACING
IMPELLER
1. Unplug the pump.
2. Loosen the clamps on the hose and clamp assembly.
3. Slide the hose and clamp assembly up on the discharge
pipe and remove the pump from the sump.
4. Turn the pump upside down and remove the screw securing
the pump screen.
5. Loosen and remove the clamp that holds the lower and
upper pump housings together. Remove the lower pump
housing.
6. Hold the motor shaft with a screwdriver in the slot on the
bottom end of the shaft, and unscrew the impeller off of the
shaft.
7. Clean and replace the impeller as necessary.
8. Reverse Steps 1 through 6 above to replace the impeller
and reinstall the pump.
9. Fill the sump with water and run the pump through one
complete cycle to make sure that it is correctly reassembled
and operating as it should.
AUTOMATIC FLOAT SWITCH INSTALLATION
1. Install pump following installation and operating instructions.
2. Automatic float switch is sealed and factory adjusted for
most home sumps. See Page 1 for switch settings.
3. Be sure that horizontal float switch clearance is 8". For
best performance of pumps with tethered switches, sump
diameter and sump depth should be at least 14".
4. Plug piggyback switch cord into 115V AC outlet. Then,
plug pump into piggyback switch cord. Do not allow cord
to interfere with float control motion or to drape over pump
motor. With electrician's tape or cable ties secure cord to
discharge pipe for cord protection.
FLOAT SWITCH OPERATIONAL CHECK
1. Fill the sump with correct amount of water to check operation and tightness of connections. During the first automatic cycle, it may take 30 seconds or more before pump
is primed and pumping. Pump will start as indicated in
the “Motor, Switch and Cord” Specifications Table, Page
1.
2. Check turn-off position. Pump will stop approximately as
indicated in the “Motor, Switch and Cord” Specifications
Table, Page 1.
3. If pump does not operate check electrical service.
NOTICE: Float switch tether length is set at factory. It is
3" (76mm) for SP75 Series pumps. Do not change tether
length of float switch. Float must swing through its complete arc without interference.
