Physical Installation

Risk of severe injury or death by electrical shock.
• Always disconnect the electrical power before touching the pump or discharge.
• Check local electrical and building codes before installation. The installation must be in accordance
with their regulations as well as the most recent National Electrical Code (NEC).
1. Pump must be installed in a suitable basin that is at least 18" (457 mm) deep, and in accordance with
local plumbing codes. Refer to
2. Clean any debris from the basin and set the pump in the center of the basin (refer to
nections" on page 6).
3. The pump must be placed on a hard, level surface. Never place the pump directly on clay, earth or
gravel surfaces. These surfaces contain small stones, gravel, sand etc. that may clog or damage the
pump and cause pump failure.
4. Do not attempt to restrict the intake side of these pumps. Restricting the intake may cause damage to
the seal and may starve the pump. If you require reduced flow rates, place a valve on the discharge side
of the pump. Or, if flexible vinyl tubing is used, a clamp can be used on the tubing to restrict the flow.
5. Connect discharge piping. Use pipe joint compound at all connections. Sump pumps can be piped to
discharge into the house drainage system, to a dry well, splash block, or to a storm drain, depending on
local plumbing codes. The discharge pipe should be as short as possible and contain as few elbows as
possible. The discharge pipe should be the same diameter, or larger than, the pump discharge size. A
smaller pipe will restrict capacity and reduce pump performance. The pump comes with a 1-1/2" FNPT
discharge and a 1-1/4" FNPT reducing bushing.
• Support the pump and piping while assembling and when installed. Failure to do so may cause the
piping to break, the pump to fail, motor bearing failures, etc.
• Always install a union in the discharge line just above the basin cover to allow for easy removal of
the pump for cleaning or repair.
6. A full flow check valve must be used in the discharge line to prevent back-flow of liquid into the basin.
A missing, improperly installed, or malfunctioning check valve can cause a pump to short-cycle due to
back-flow of the pumped fluid from the discharge plumbing back into the basin, significantly shorten-
ing the life of the pump.
Risk of property damage due to flooding.
• When a check valve is used, drill a relief hole 1/8 – 3/16" (3.2 – 4.8 mm) in diameter in the discharge
pipe. This hole should be located below the floor line between the pump discharge and the check
valve. Unless such a relief hole is provided, the pump could "air lock" and will not pump water even
though it will run.
7. Tape the pump and switch cords to the discharge pipe with electrical tape to keep the power cords
securely routed away from the pump inlet and any control floats.
8. Connect the pump to an appropriate power supply following the instructions in
tions" on page 6.
9. Test the operation of the pump system by following the instructions in
this manual. Do not attempt to operate the pump without water; this will damage the seals and bear-
ings and could result in permanent damage to the pump.
10. Place cover over basin. This cover will help prevent debris from entering the pit and will guard against
accidental injury.
