Installation and Operation
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 con-
ductor 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 encoun-
tered, it must be replaced with properly
grounded 3-prong receptacle installed in accor-
dance with codes and ordinances that apply.
13. All wiring should be performed by a qualified
electrician.
14. Make certain power source conforms to require-
ments of your equipment.
15. Protect electrical cord from sharp objects, hot
surfaces, oil, and chemicals. Avoid kinking cord.
Replace or repair damaged or worn cords imme-
diately.
16. Do not touch an operating motor. Modern motors
can operate at high temperatures.
17. Do not handle pump or pump motor with wet
hands or when standing on wet or damp surface,
or in water.
Hazardous voltage can shock, 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 ser-
vice to house, or call your local fire department for
instructions. Remove pump and repair or replace.
Failure to follow this warning can result in fatal
electrical shock.
Do not lift pump by power cord.
FLOAT SWITCH INSTALLATION
Models equipped with vertical switches require some
assembly. See the Switch Assembly instructions on
Page 4. Models with tethered float switches are
ready for use.
INSTALLATION
1. Install pump in sump pit with minimum diameter
of 10" (254mm) for models equipped with verti-
cal switches and 14" (356mm) for tethered float
switch models. Sump depth should be 16"
(406mm) for tethered models and 10" (254mm)
for vertically switched models. Construct sump
pit of tile, concrete, steel or plastic. Check local
codes for approved materials and for proper
installation.
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.
For parts or assistance, call Diamond Customer Service at
NOTICE: Do not use ordinary pipe joint com-
pound on plastic pipe. Pipe joint compound can
attack plastics.
4. Install discharge plumbing. Use rigid plastic pipe
and wrap threads with Teflon
into pump hand tight plus 1-1/2 turns.
Risk of flooding. If a flexible dis-
charge 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 rubber hose (1-7/8" (47.6mm) I.D., e.g.
radiator hose) can be connected into discharge
line near pump using suitable clamps.
6. Install an in-line check valve or an in-pump check
valve to prevent flow backwards through pump
when pump shuts off.
NOTICE: If your check valve is not equipped with
an air bleed hole to prevent airlocking pump, drill
a 1/8" (3.2 mm) hole in discharge pipe just above
where the discharge pipe screws into the pump
discharge. Be sure the hole is below the waterline
and the check valve to prevent air locks.
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 ground-
ing-type plugs. Switch plug is inserted directly
into outlet and pump plug inserts into opposite
end of switch plug.
Pump should always be electrical-
ly grounded to a suitable electrical ground such
as a grounded water pipe or a properly ground-
ed 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, check valve and float switch have
been installed, the unit is ready for operation.
10. Check the pump operation by filling sump with
water and observing pump operation through one
complete cycle. For switch settings see the Electrical
and Switch Specifications chart on Page 2.
Failure to make this operational
check may lead to improper operation, prema-
ture failure, and flooding.
