Installation
Handle with care. Check the items received against
the packing list to be sure that all equipment has been
received. Inspect the pump for shipping damage. If any is
found, contact your retailer immediately.
NOTICE Do not reduce size of discharge pipe or hose
below 1-1/2" diameter for effluent applications or 2" for
sewage applications. If discharge is too small, pump will
overheat and fail prematurely.
NOTICE This unit is not designed as a waterfall or
fountain pump, or for applications involving recirculating
water, salt water or brine! Use with waterfalls, fountains,
salt water or brine will void warranty.
1. Install the pump on a solid, level foundation, or in
a sump pit constructed of tile, concrete, steel or
plastic. Pump must be level when operating. If motor
is tilted, internal start/run switch may overheat and
damage motor.
2. The recommended minimum diameter of the sump
pit is 14" (36cm) diameter and the minimum
recommended depth is 30" (76cm). Check local
codes for approved materials.
NOTICE Pump should not be installed on clay, earth
or sand surfaces. Clean the area around the pump of
small stones and gravel which could clog the pump.
Keep the pump inlet screen clear.
3. Thread a 2" discharge pipe into the pump 2" NPT
discharge port. Be careful to avoid stripping or
crossing threads. Reduce the number of bends in the
discharge piping to keep the outlet flow as smooth as
possible. Install the pump with a pipe union in the
discharge piping to allow removal for servicing. Use
PTFE tape on pipe threads. Do not use ordinary pipe
joint compound on plastic pipe or pump. Pipe joint
compound can attack plastics and damage pump.
Pi ping – Effluent Applications (3/4" or
Less Solids)
Piping must be 1-1/2" minimum to carry volume of
pump discharge. Check local codes to determine if a
check valve is required in your system. In cold climates,
check valves are not used to prevent effluent from
freezing in piping.
Hazardous
voltage
Risk of electrical shock.
Can burn or kill.
Do not lift pump by power cord.
Pi ping – Sewage Applications (2" or
Less Solids)
In any case, piping must not be smaller than
pump discharge.
When installed in a sewage system, pipe must
be capable of handling semi-solids of at least 2"
(5.1 cm) diameter.
The rate of flow in the discharge pipe must keep any
solids present in suspension in the fluid. To meet
minimum flow requirements (2 feet (.6 m) per second in
discharge line), size pipe as follows:
The pump must always be lifted by the lift-out chain or
cable and never by the power supply cable. See Cord
Lift Warning.
4. To reduce motor noise and vibrations, a short length
of rubber hose (1-5/8"(41mm) I.D., e.g. radiator
hose) can be connected into discharge line near
pump using suitable clamps.
5. If the pump discharge line is exposed to outside
subfreezing atmosphere, then the portion of line
exposed must be installed so any water remaining in
pipe will drain to outfall by gravity. Failure to do this
can cause water trapped in discharge to freeze which
could result in damage to pump.
6. Install a 2" check valve in the horizontal portion of
the discharge pipe. Make certain, the flow indicating
arrow, points away from the pump. This check valve
will keep the water from either running back into the
basin or into the area being pumped out when the
pump is not running. Check valve should be a free
flow valve that will easily pass solids.
Cord Lift Warning
Pipe Size (In/cm) Flow Rate (GPM/LPH)
1-1/2 (3.8)
2 (5.1)
2-1/2 (6.3)
3 (7.6)
Risk of electrical shock and fire.
1. Attempting to lift or support the pump by
the power cord can damage cord and cord
connections, expose bare wires, and cause a fire
or electrical shock.
2. Use handle on top of pump for all lifting or
lowering of pump. Disconnect the power to the
pump before doing any work on it or attempting
to remove it from the pit.
3. Lifting or supporting the pump by the power
cord will void the warranty.
