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, elec-
trical or mechanical failure in the pump, etc.) may pre-
vent your pump from functioning normally. To prevent
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 problems and remedies. For
more information, see your retailer or call Diamond cus-
tomer service at 1-800-265-7241.
1. Know the pump application, limitations, and poten-

tial 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 unse-

cured discharge line will whip, possibly causing per-
sonal injury and/or property damage.

6. Check hoses for a weak or worn condition before

each use, making certain that all connections are
secure.

7. Periodically inspect sump, pump and system compo-

nents. Keep free of debris and foreign objects.
Perform routine maintenance as required.

8. Provide a 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, mas-

ter 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-conduc-
tor cord and 3-prong, grounding-type plug.

Risk of electrick shock. Can burn or

kill.

To reduce risk of electric shock, pull plug before

servicing.
Pump is supplied with a grounding conductor and
grounding-type attachment plug. Be sure it is con-
nected only to a properly 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.

12. All wiring should be performed by a qualified

electrician.

13. Make certain power source conforms to require-

ments of your equipment.

14. Protect electrical cord from sharp objects, hot sur-

faces, oil, and chemicals. Avoid kinking cord. Replace
or repair damaged or worn cords immediately.

15. Do not touch an operating motor. Modern motors

can operate at high temperatures.

16. Do not handle pump or pump motor with wet hands

or when standing on wet or damp surface, or in
water.

Risk of electrick shock. Can burn or kill.

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 instructions. Remove pump and
replace it. Failure to follow this warning can result in
fatal electrical shock.
17. Do not use this pump in water where fish are present.
18. This pump has not been investigated for use in

swimming pool areas.

Oil on the pump or in the sump may indicate motor
leakage and an electrical shock hazard. Turn off power
and check pump for oil leakage from impeller area.
Replace pump if it leaks.

INSTALLATION

1. Install pump in a sump pit with a minimum

diameter of 10" (254 mm). Sump depth should be
18" (457 mm). Construct sump pit of tile, concrete,
steel or plastic. Check local codes for approved
materials.

2. Install pump in pit so that switch operating mecha-

nism 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.
