Installation
INSTALLATION
NOTICE: Install pump on a hard, level surface (cement, asphalt,
etc.). Never place pump directly on earth, clay or gravel
surfaces.
Piping – (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” diameter. The rate of flow in
the discharge pipe must keep any solids present in suspension
in the fluid. To meet minimum flow requirements, the minimum
pipe size is 2”.
Use a 2” swing check valve in pump discharge to prevent
backflow of liquid into sump basin. Check valve should be a
free flow valve that will easily pass solids.
NOTICE: For best performance of check valve when handling
solids, do not install it with discharge angled more than 45°
above the horizontal. Do not install check valve in a vertical
position as solids may settle in valve and prevent opening on
startup.
Drill a 3/16” hole in discharge pipe about 1”-2” above pump
discharge connection (but below check valve) to prevent
airlocking the pump.
Electrical
WARNING: Risk of electric shock. Can shock, burn
or kill. When installing, operating, or servicing this
pump, follow safety instructions listed below.
Step 1. DO NOT splice the electrical power cord.
Step 2. DO NOT allow electrical cord plug to be submerged.
Step 3. DO NOT use extension cords. They are a fire hazard and
can reduce voltage sufficiently to prevent pumping
and/or damage motor.
Step 4. DO NOT handle or service pump while it is connected to
power supply.
Step 5. DO NOT remove grounding prong from plug or modify
plug. To protect against electrical shock, the power cord
is a three-wire conductor and includes a 3-prong
grounded plug. Plug pump into a 3-wire, grounded,
grounding type receptacle. Connect pump according to
electrical codes that apply.
For automatic operation, plug pump into an automatic float
switch or pump controller. Pump will run continuously when
plugged directly into an electrical outlet. Connect or wire
pump to an individual branch circuit with no other outlets or
equipment in the circuit.
AUTOMATIC - Plug the pump power cord plug into the piggy-
back switch plug outlet, and then plug the switch plug into a
115V GFCI power outlet for automatic operation. The pump
will start operating if the float switch moves over the top of the
pump. The water will be pumped out. When the water lowers to
a certain level, the float switch will turn off the pump.
MANUAL - Plug the pump power cord plug into a 115V GFCI
power outlet directly for manual operation. Pump will start
operating once it is pluged into the GFCI outlet and water will
drain out. When water is drained out, you must unplug the
pump.
Size fuses or circuit breakers according to chart below.

OPERATION
NOTICE: Do not allow pump to run in a dry sump. It will void
the warranty and may damage the pump. An automatic
overload protector in the motor will protect motor from
burning out due to overheating / overloading.
When motor cools down, overload protector will automatically
reset and start motor. If overload trips frequently, check for
cause. It could be a stuck impeller, wrong/low voltage, or
electrical failure in motor. If an electrical failure in the motor is
suspected, have it serviced by a competent repairman.
