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 a properly grounded 3-prong
receptacle installed in accordance with codes and
ordinances that apply.
12. A ground fault circuit is recommended for use with any
electrical appliance submerged in water. Installation and
all wiring should be performed by a qualified electrician.
13. Make certain power source conforms to requirements of
your equipment.
14. Protect electrical cord from sharp objects, hot surfaces,
oil, and chemicals. Avoid kinking cord. Replace or repair
damaged or worn cords immediately.
15. Do not touch an operating motor. 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 electric shock. 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.
Failure to follow this warning can result in fatal electrical
shock. Remove pump and repair or replace.
DESCRIPTION
This Submersible Sump Pump is designed for home sumps. Unit
is equipped with a 3-prong grounding-type power cord. The per-
manent split capacaitor motor is oil filled and sealed for cooler
running. The sleeve bearings on the motor shaft never need
lubrication. The pump includes automatic reset thermal protec-
tion.
Pump water only with this pump.

NOTE: For model B75-M1, purchase switch separately. Follow
switch manufacturer's instructions for installation. Switch must
be rated to meet code and adequately control a 3/4 HP, 7.5
amp, 115 volt motor. Be sure sump is large enough to allow
for free operation of switch. Model B75-V1 includes vertical
switch.

INSTALLATION
1. Install the pump in a sump pit constructed of tile, concrete,
steel, or plastic (check your local codes for approved mate-
rials). Pit diameter must be at least 10" (254mm) for model
B75-V1 and 14" (356mm) for model B75-M1 equipped with
a tethered float switch (purchase switch separately). Do not
install the pump on a clay, earth, or sand surface.
2. Make sure the pit is free of small stones, gravel, and any
other debris which could clog the pump.
3. Make sure that the switch has the maximium possible
clearance from the sump wall, etc.
4. Install the discharge piping. Use rigid piping in any perma-
nent installation. Cut the piping so that it stops about 1/2"
short of the pump discharge.
secured so it cannot move around in the sump. If it moves,
interference between the switch and the sump wall may
prevent the pump from starting or stopping, causing flood-
ing or damage to the pump.
NOTE the following:
• Use plastic pipe for a rigid discharge pipe installation.
• Do not use ordinary pipe joint compound on plastic pipe.
Pipe joint compound can attack plastics, causing
cracking and failure.
• Keep the discharge piping as short as possible to reduce
friction in the pipe.
• The discharge pipe's diameter should be at least as
large as the diameter of the pump's discharge port.
• A pipe smaller than the port diameter will constrict the
flow, reduce performance, and lead to early pump failure.
A larger pipe may require adapters to fit the pump
discharge.
• Pump has an internal check valve to prevent flow back-
wards through pump when it is shut off.
5. Loosen the coupling clamps and slide the discharge cou-
pling up the discharge pipe an inch or two. Place the pump
in the sump and slide the coupling down over the pump
discharge (so it holds both the pump discharge and the
discharge pipe). Tighten the coupling clamps. Secure the
discharge line before starting the pump.
6.
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 modify
cord or plug or cut off round ground pin. Install the
pump on a 115V/ 60Hz/15Amp individual branch circuit.
• B75-V1: Both the pump and the switch are supplied with
3-wire cords with grounding-type plugs. For automatic
operation, plug the switch into the wall outlet and plug the
pump into the switch plug. For continuous operation, plug
the pump directly into the wall outlet.
• B75-M1: The pump is supplied with a 3-wire cord with
grounding type plug. Plug the pump directly into the wall
outlet for manual operation.
7. If water is trapped in the discharge pipe and freezes, it
could cause damage to the pump. If the discharge pipe
will be exposed to sub-freezing temperatures, install the
pipe so that it will drain completely when the pump stops.
8. After the piping has been installed, the unit is ready for
operation.
