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 dealer about installing a secondary 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 dealer or call customer service at
1-888-782-7483.
1. Know the pump application, limitations, and potential
hazards.
2. Disconnect the power before servicing.
3. Release all pressure within the system before servicing
any component.
4. Drain all water from the system before servicing.
5. Secure the discharge line before starting the pump. An
unsecured discharge line will whip, possibly causing per-
sonal injury and/or property damage.
6. Check the hoses for a weak or worn condition before
each use. Make certain all connections are secure.
7. Periodically inspect the 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 dis-
charge line can be shut-off or obstructed.
9. Personal Safety:
a. Wear safety glasses at all times when working with
pumps.
b. Keep the 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 the workshop child-proof – with padlocks, mas-
ter switches, and by removing starter keys.
10. When wiring an electrically driven pump, follow all electri-
cal 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.
Electrical shock hazard. Can burn or
kill. To reduce risk of electric shock, pull plug before ser-
vicing. 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.
This pump has not been investigated for use in swim-
ming pool areas.
12. All wiring should be performed by a qualified electrician.
13. Make certain the power source conforms to the require-
ments of your equipment.
14. Protect the electrical cord from sharp objects, hot sur-
faces, oil, and chemicals. Avoid kinking the cord. Replace
or repair damaged or worn cords immediately.
15. Do not touch an operating motor. Modern motors are
designed to operate at high temperatures.
16. Do not handle the pump or pump motor with wet hands
or when standing on wet or damp surface, or in water.
Electrical shock hazard. Can 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.
17. Vent the sewage or septic tank according to the local codes.
18. Do not install the pump in any location classified as
hazardous by the National Electric Code, ANSI/NFPA
70-1984 or the Canadian Electrical Code.

INSTALLATION

1. Install the pump in a sump pit with a minimum diameter
of 10" (254mm) for models equipped with vertical switch-
es and 14" (356mm) for tethered float switch models. The
sump depth should be 15" minimum (381mm). Construct
the sump pit of tile, concrete, steel or plastic. Check the
local codes for approved materials.
2. NOTE: When installing the vertical switch, the rod stop
(Key No. 1F, page 4) must not be pushed up farther than
the bottom nib on the float rod. Pushing it any farther up
the rod will cause the switch to hang up on the pump
discharge and will damage the pump.
Figure 1
3. The pump should not be installed on clay, earth or sand sur-
faces. Clean the sump pit of small stones and gravel which
could clog the pump. Keep the pump inlet screen clear.
4. Install the pump in the pit so that the switch operating
mechanism has maximum possible clearance.
5. Install the discharge plumbing. When using rigid pipe,
use plastic pipe. Wrap the threads with Teflon tape
Screw the pipe into the pump hand tight +1 – 1-1/2 turns.
NOTICE: Do not use ordinary pipe joint compound on
plastic pipe. Pipe joint compound can attack plastics and
damage the pump.
Risk of flooding. If a flexible discharge
hose is used, make sure the pump is secure in the sump
to prevent movement. Failure to secure the pump may
allow pump movement, switch interference and prevent
the pump from starting or stopping.
6. To reduce motor noise and vibrations, a short length of
rubber hose (e.g. radiator hose) can be connected into
the discharge line near the pump using suitable clamps.
7. Install an in-line check valve to prevent backward flow
through the pump when the pump shuts off.
8. Power Supply: The pump is designed for 115 V., 60 Hz.,
operation and requires a minimum 15 amp individual
branch circuit (refer to Motor, Switch and Cord
Specifications chart, Page 1). Both the pump and switch
are supplied with 3-wire cord sets with grounding-type
plugs. The switch plug is inserted directly into the outlet
and the pump plug inserts into the opposite end of the
switch plug.
