Product Manual

INSTALLATION
Hazardous voltage. Can shock, burn or kill.
Do not lift pump by the power cord. See “Cord Lift Warning”
on Page 3.
NOTICE: Install the pump on a hard, level surface (cement,
asphalt, etc.). Never place the pump directly on earth, clay or
gravel surfaces.
Piping
Piping must not be smaller than pump discharge.
When installed in an effluent system, the pipe must be
capable of handling semi-solids of at least 3/4" (19mm) in
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 per second in the discharge line), size
the pipe as follows:
A Pipe Size Of: Will Handle a Flow Rate Of:
1-1/2" (38mm) 12 GPM
2" (51mm) 21 GPM
2-1/2"(64mm) 30 GPM
3"(76mm) 48 GPM
In an effluent system use a 1-1/2" (38mm) check valve
in pump discharge to prevent backflow of liquid into sump
basin. The check valve should be a free flow valve that will
easily pass solids. Be sure check valve installation complies
with local codes.
NOTICE: For best performance of check valve when
handling solids, do not install it with the discharge more than
45° above the horizontal. Do not install the check valve in a
vertical position as solids may settle in the valve and prevent
it from opening on startup.
Drill a 3/16" (5mm) hole in the discharge pipe about 1–2"
(25-51mm) above the pump discharge connection (but below
check valve) to prevent airlocking the pump.
Electrical
Hazardous voltage. Can shock, burn, or
kill. When installing, operating, or servicing this pump, follow
the safety instructions listed below.
1. DO NOT splice the electrical power cord.
2. DO NOT allow the electrical cord plug to be submerged.
3. DO NOT use extension cords. They are a fire hazard and
can reduce voltage sufficiently to prevent pumping and/or
damage motor.
4. DO NOT handle or service the pump while it is
connected to the power supply.
5. DO NOT remove the grounding prong from the plug
or modify the plug. To protect against electrical shock,
the power cord is a three-wire conductor and includes
a 3-prong grounded plug. Plug the pump into a 3-wire,
grounded, grounding-type receptacle. Connect the pump
according to the NEC or CEC and local codes.
For automatic operation, plug or wire the pump into an
automatic float switch or duplex controller. The pump will run
continuously when plugged directly into an electrical outlet.
Connect or wire pump to its own individual branch circuit
with no other outlets or equipment in the circuit. Size fuses
or circuit breakers according to the “Motor, Switch and Cord
Specifications” chart.
Risk of electrical shock and fire. Can
burn, kill or cause property damage. Be sure that power
supply information (Voltage/ Hertz/Phase) on pump motor
nameplate matches incoming power supply exactly. Install
pump according to all electrical codes that apply.
OPERATION
Risk of fire or explosion. Can cause severe
personal injury, property damage or death. Do not use in
explosive atmospheres. Pump water only with this pump.
NOTICE: Do not allow the 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
the motor from burning out due to overheating/overloading.
When the motor cools down, the overload protector will
automatically reset and start the motor.
If the overload trips frequently, check for the cause. It could
be a stuck impeller, wrong/low voltage, or an electrical failure
in the motor. If an electrical failure in the motor is suspected,
have it serviced by a competent repairman.
The pump is permanently lubricated. No oiling or greasing is
required.
SERVICE
General
Hazardous voltage and risk of cord
damage. Can shock, burn, or kill. Before removing the
pump from the basin for service, always disconnect electrical
power to the pump and the control switch. Do not lift the
pump by the power cord. See the “Cord Lift Warning” below.
After removing the basin cover and the necessary discharge
piping, lift the pump out of the basin.
Place the pump in an area where it can be cleaned
thoroughly. Remove all scale and deposits on the pump.
Submerge the complete pump in a disinfectant solution
(chlorox or chlorine bleach) for at least one hour before
disassembling the pump.
The pump motor housing contains a special lubricating oil
which should be kept clean and free of water at all times.
NOTICE: Whenever the motor housing is being removed for
service, remove oil and replace it with new oil at reassembly.
Use only oil listed in parts list in this manual. When filling
with new oil, DO NOT overfill. Allow about 7/8" (22mm) air
space from top of boss in housing for expansion of oil when
the pump is operating.
Pump Disassembly
Impeller and Seal Replacement
A. Impeller removal (See the pump disassembly drawing,
Page 4):
1. Remove the oil fill plug and turn the pump upside
down to drain oil.
2. Remove the capscrews holding the upper motor
housing to the lower motor housing; lift off the upper
motor housing and remove the motor lead wires from
the connector to detach upper housing from assembly.
The lead wires are fitted with quick connect terminals
for this purpose.
