Float Switch Installation

Models equipped with vertical switches require some
assembly. 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 vertical
switches and 14” (356mm) for tethered float switch
models. Sump depth should be 18” (457mm) for
tethered models and 13” (330mm) 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.

NOTICE Do not use ordinary pipe joint compound on
plastic pipe. Pipe joint compound can weaken plastics.

Liquid Temp. Range..........................32°F to 70°F(0°-21°C)

Individual Branch Circuit Required (min.).............15 Amps

Discharge:........................................................ 1-1/2” NPT

NOTICE Do not reduce size of discharge pipe or hose
below 1-1/4” diameter. If discharge is too small, pump will
overheat and fail prematurely.

This pump is designed for use in a residential sump only.

Only pump water with this pump.
NOTICE This unit is not designed as a waterfall or fountain

pump, or for applications involving salt water or brine!
Use with waterfalls, fountains, salt water or brine will void
warranty.
Do not use where water recirculates.

Not designed for use as a swimming pool drainer.

For parts or assistance, call Flotec Customer Service at 1-800-365-6832

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

PTFE pipe thread sealant tape

.

Hand tighten pipe into pump plus 1-1/2 turns.

Risk of flooding. Can cause personal injury
and/or property damage. 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 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 grounding-type plugs.
Switch plug is inserted directly into outlet and pump
plug inserts into opposite end of switch plug.

Risk of electric shock. Can shock, burn or
kill. 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 sub-freezing
weather conditions, portion of exposed pipe must
be installed so any water remaining will drain out or
down due to 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.

Risk of flooding. Can cause personal injury
and/or property damage. Failure to make this operational
check may lead to improper operation, premature failure,
and flooding.

Operation ∙ Troubleshooting 5

Symptom Possible Cause(s) Corrective Action

Pump won’t start
or run.

Pump is not plugged in. Check and see if pump is plugged into a proper outlet.
Blown fuse. If blown, replace with fuse of proper size.

Low line voltage

If voltage under recommended minimum, check size
of wiring from main switch on property. If OK, contact

power company or hydro authority.
Defective motor. Replace pump.
Defective float switch. Replace float switch.

Impeller

If impeller won’t turn, remove lower pump body and

locate source of binding.
Float obstructed Remove obstruction.

Pump starts and
stops too often.

Backflow of water from piping Install or replace check-valve.
Faulty float switch Replace float switch.

Pump won’t shut
off

Defective float switch Replace float switch.
Restricted discharge (obstacle
or ice in piping)

Remove pump and clean pump and piping.

Float obstructed Remove obstruction.

Restricted intake screen

Remove the pump and clean the intake screen and the

impeller.

Pump operates
but delivers little
or no water

Low line voltage

If voltage under recommended minimum, check size

of wiring from main switch on property. If OK, contact

power company or hydro authority.
Something caught in impeller Remove the pump and clean out the impeller.
Worn or defective parts or
plugged impeller

Clean impeller if plugged; otherwise replace pump.

Check valve installed without
vent hole.

Drill a 1/16” - 1/8” (1.6mm-3.2mm) dia. hole between

pump discharge & check valve (1-2” above where the

discharge pipe screws into the pump discharge and

below the waterline).
Restricted intake screen Remove the pump and clean out the intake screen.
Check valve is installed either
backward or upside down

Be sure check valve is installed correctly.

Operation

Risk of electric shock. Can shock, burn or
kill. 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, switch
will cut off all power before damage can be done
to motor. When motor has cooled, switch will reset

automatically and restart motor. If protector trips
repeatedly, pump should be removed and checked.
Low voltage, long extension cords, clogged impeller,
very low head or lift, or a plugged or frozen discharge
pipe, etc., could cause protector to trip.

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 unit
has broken prime due to a very low water level.

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