PERFORMANCE

ELECTRICAL & SWITCH SPECIFICATIONS

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 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, call Flotec customer service at
1-800-365-6832 or visit our website at
www.flotecwater.com.

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

2. Do not use in water with fish present. If any oil

leaks out of the motor it can kill fish.

3. Disconnect power before servicing.

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

5. Drain all water from system before servicing.

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

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

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

9. Provide means of pressure relief for pumps whose
discharge line can be shut-off or obstructed.

10. 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.

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

12. 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 properly grounded
3-prong receptacle installed in accordance with
codes and ordinances that apply.

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

14. Make certain power source conforms to
requirements 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
immediately.

16. Do not touch an operating motor. Modern motors
can operate at high temperatures.

Installation and Operation 3

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
service 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

See the Switch Assembly instructions on Page 4.

INSTALLATION

1. Install pump in sump pit with minimum diameter
of 10" (254mm). Sump depth should be 10”
(254mm). 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.

NOTICE: 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 1TeflonTMtape. Screw pipe
into pump hand tight plus 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 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: Check valves should be equipped with
an air bleed hole to prevent airlocking pump. If
not, 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
grounding-type plugs. Switch plug is inserted
directly into outlet and pump plug inserts into
opposite end of switch plug.

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 sub­freezing 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,
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 damaged 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, or
a plugged or frozen discharge pipe, etc., could
cause cycling.

3. Pump will not remove all water. If operating a
pump manually, and suddenly no water comes
out of the discharge hose, shut off the unit
immediately. The water level is probably very low
and the unit has broken prime.

NOTICE: For continuous operation, water depth
must be at least 5" (127mm) to prevent the
motor from overheating. A fully submerged
pump is preferred for proper cooling when a
pump runs continuously.

Risk of electric shock. Before
attempting to check why unit has stopped
operating, disconnect power from unit.
