GENERAL SAFETY INFORMATION

READ AND FOLLOW

SAFETY INSTRUCTIONS!

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 pre-

vent possible water damage due to flooding, consult your retailer

about a secondary AC 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 prob-

lems and remedies.

Know the pump application, limitations, and potential hazards.

Disconnect power before servicing.

Release all pressure within system before servicing any component.

Drain all water from system before servicing.

Secure discharge line before starting pump. An unsecured dis-

charge line will whip, possibly causing personal injury and/or

property damage.

Check hoses for weak or worn condition before each use, mak-

ing certain that all connections are secure.

Periodically inspect sump, pump, and system components. Keep

free of debris and foreign objects. Perform routine maintenance

as required.

Personal Safety:

1. Wear safety glasses at all times when working with pumps.

2. Keep work area clean, uncluttered, and properly lighted –

replace all unused tools and equipment.

3. Keep visitors at a safe distance from work area.

4. Make workshop child-proof – with padlocks, master switch-

es, and by removing starter keys.

When wiring an electrically driven pump, follow all electrical

and safety codes that apply.

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 swim-

ming pool areas. Pump is supplied with a grounding conductor and

grounding-type attachment plug. Be sure it is connected only to a proper-

ly grounded grounding-type receptacle. Where a 2-prong wall receptacle

is encountered, it must be replaced with properly grounded 3-prong

receptacle installed in accordance with codes and ordinances that apply.

All wiring should be performed by a qualified electrician.

Make certain power source conforms to requirements of your

equipment.

Installation / Operation 3

Protect electrical cord from sharp objects, hot surfaces, oil, and

chemicals. Avoid kinking cord. Replace or repair damaged or

worn cords immediately.

Do not handle pump or pump motor with wet hands or when

standing on wet or damp surface, or in water.

Do not use this pump in a fish pond.

Risk of electrical shock. Can burn or kill. If your

basement has water or moisture on floor, do not walk on wet

area until all power has been turned OFF. If shut-off box is in

basement, call electric company or hydro authority to shut-off

service to house, or call your local fire department for instruc-

tions. Remove pump and repair or replace. Failure to follow this

warning can result in fatal electrical shock. Oil on the pump or

in the sump may indicate motor leakage and electrical shock

hazard. Turn OFF power and check pump for oil leakage from

impeller area. Replace pump if it leaks.

NOTE: This unit is not designed for applications involving salt

water or brine! Use with salt water or brine will void warranty.

Pump water only with this pump.

INSTALLATION

1. Install pumps in sump pit with minimum diameter of 12".

Sump depth should be 18". Construct sump pit of tile, con-

crete, 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.

NOTE: Do not use ordinary pipe joint compound on plastic

pipe. Pipe joint compound can attack plastics.

4. Install discharge plumbing. Use rigid plastic pipe and wrap

threads with Teflon tape or use Plasto Joint Stik1. Screw pipe

into pump hand tight +1 to 1-1⁄2 turns.

Risk of flooding. If a flexible discharge hose is

used, make sure pump is secured in sump to prevent movement.

Failure to secure pump may allow pump movement, switch

interference, and prevent pump from starting or stopping.

5. To reduce motor noise and vibrations, a short length of rub-

ber hose (1-7⁄8" I.D., e.g. radiator hose) can be connected

into discharge line near pump using suitable clamps.

6. Install an in-line check valve to prevent flow backwards

through pump when pump shuts off.

7. Power Supply: Pump is designed for 115 V., 60 Hz., opera-

tion and requires a minimum 15 amp dedicated circuit. Both

pump and switch are supplied with 3-wire cord sets with

grounding-type plugs. For automatic operation, switch plug is

inserted directly into outlet and pump plug inserts into oppo-

site end of switch plug. For manual operation, pump plug is

inserted directly into outlet.

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.

8. 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.

9. After piping and check valve have been installed, unit is

ready for operation.

10. Check operation by filling sump with water and observing

pump operation through one complete cycle.

Failure to make this operational check may

lead to improper operation, premature failure, and flooding.

OPERATION

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. Shaft seal depends on water for lubrication. Do not operate

pump unless it is submerged in water as seal may be dam-

aged if allowed to run dry.

2. 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 as to cause of difficulty. Low voltage,

long extension cords, clogged impeller, very low head or lift,

etc., could cause cycling.

3. Pump will not remove all water. If manually operated pump

is operating and suddenly no water comes out of discharge

hose, shut OFF unit immediately. Water level is probably

very low and unit has broken prime.

NOTE: For continuous operation, water depth must be at least 2"

(5 cm).

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.

NOTE: No repair parts are available for these pumps.
