Installation
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.
17. 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. 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 re place. Failure to follow this warning can result
in fatal electrical shock.

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 attack plastics.
4. Install discharge plumbing. Use rigid plastic pipe and
wrap threads with PTFE pipe thread sealant tape.
Screw pipe into pump hand tight 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.
