GENERAL SAFETY INFORMATION

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 the pump from functioning normally. To prevent

possible water damage due to flooding, consult your
dealer about installing a high water alarm. See the

“Troubleshooting Chart” in this manual for information

about common sump pump problems and remedies.
For more information, see your dealer or call customer
service.

1. Know the pump application, limitations, and potential
hazards.

2. Disconnect power before servicing.

3. Release all pressure within system before servicing any
component.

4. Drain all water from system before servicing.

5. Secure discharge line before starting pump. An
unsecured discharge line will whip, possibly causing
personal injury and/or property damage.

6. Check hoses for weak or worn condition before each
use, making certain that all connections are secure.

7. Periodically inspect system components. Keep
free of debris and foreign objects. Perform routine
maintenance as required.

8. Provide means of pressure relief for pumps whose

discharge line can be shut-off or obstructed.

9. Personal Safety:
a. Wear safety glasses at all times when working with

pumps.

b. Keep work area clean, uncluttered and properly

lighted – replace all unused tools and equipment.
c. Keep visitors at a safe distance from work area.
d. Make workshop child-proof – with padlocks,

master switches, and by removing starter keys.

10. When wiring an electrically driven pump, follow all
electrical and safety codes that apply.

11. This equipment is only for use on 115 volt (single

phase) and is equipped with an approved
3-conductor cord and 3-prong, grounding-type plug.

To reduce risk of electric shock, pull plug

before servicing. This pump has not been investigated

for use in swimming pool areas. Pump is supplied with
a grounding conductor and grounding-type attachment
plug. Be sure it is connected only to a properly grounded
grounding-type receptacle. Where a 2-prong wall
receptacle is encountered, it must be replaced with
a properly grounded 3-prong receptacle installed in
accordance with codes and ordinances that apply.

12. All wiring should be performed by a qualified
electrician.

13. Make certain power source conforms to requirements
of your equipment.

14. Protect electrical cord from sharp objects, hot surfaces,
oil, and chemicals. Avoid kinking cord. Replace or
repair damaged or worn cords immediately.

15. Do not touch an operating motor. Modern motors are
designed to operate at high temperatures.

2. Install discharge plumbing. When using rigid pipe,

use plastic pipe. Wrap thread with PTFE pipe thread

sealant tape. Screw pipe into discharge fitting hand

tight +1 – 1-1⁄2 turns.

NOTE: Do not use ordinary pipe joint compound on
plastic pipe. Pipe joint compound can attack plastics.

3. To reduce motor noise and vibrations, a short length
of rubber hose (1-7⁄8" I.D., e.g. radiator hose) can

be connected into discharge line near pump using
suitable clamps.

4. Install an in-line check valve to prevent flow
backwards through pump when pump shuts off.

5. Thread vent pipe into 1-1⁄2" NPT black vent fitting

in basin cover. Pipe should not extend into basin.
Connect vent pipe to sewer vent system.

6. 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 cut off round
ground pin.

7. If pump discharge line is exposed to outside sub­freezing atmosphere, portions 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.

8. After piping and check valve have been installed, unit
is ready for operation.

9. Check operation by filling sump with water and
observing pump operation through one complete
cycle.

Risk of flooding. Failure to make this

operational check may lead to improper operation,
premature failure, and flooding.

MAINTENANCE

Risk of electric shock. Make certain that the

pump is unplugged before attempting to service or remove
any component.

Risk of electric shock. Do not handle a

pump or pump motor with wet hands or when standing
on wet or damp surface, or in water.

1. Keep pump inlet screen clear.

2. Shaft seal depends on water for lubrication. 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, pump should be removed
and checked for cause of difficulty. Low voltage, long
extension cords, clogged impeller, very low head

or lift, etc., could cause cycling. Refer to Trouble

shooting Guide on Page 6 for additional information.

4. Periodically inspect pump, system components, and
sump for debris and foreign objects. Keep sump free of
all refuse. Perform routine maintenance as required.

Pump Cleaning

NOTE: Attempting to disassemble motor will void

warranty.

1. Use the pump ring to lift pump out of basin and place
pump on a clean level surface.

Risk of electrical shock. Shock can burn or

kill. Do not lift pump by power cord.

2. To clean impeller, remove eight screws holding

baseplate to motor assembly. Clean impeller as
necessary.

3. Re-install baseplate and screws.

4. Use pump ring to replace pump in basin.
