INSTALLATION
Risk of electrical shock. Can burn or kill.
Do not lift pump by power cord. See “Cord Lift Warning”.
NOTICE:
Install pump on a hard, level surface (cement,
asphalt, etc.). Never place pump directly on earth, clay or
gravel surfaces. Basin must be at least 18’’ (457 mm) in
diameter and 30’’ (762 mm) deep.
Piping:
Piping must not be smaller than pump discharge.
When installed in an
effluent
system, pipe must be capable
of handling semi-solids of at least 3/4’’ (19 mm) diameter.
The rate of flow in the discharge pipe must keep any solids
present in suspension in the fluid. To meet minimum flow
requirements of 2 ft. per second (61 cm/sec) in discharge
line, size pipe as follows:
A Pipe Size Of:
Will Handle a Flow Rate Of:
2’’ (51 mm)
21 GPM (79.5 L/M)
2-1/2’’ (64 mm)
30 GPM (113.5 L/M)
3’’ (76 mm)
48 GPM (182 L/M)
In an
effluent
system use a 1-1/2’’ (38 mm) min. check valve
in pump discharge to prevent backflow of liquid into pump
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 discharge 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’’ (5 mm) hole in discharge pipe about 1 to 2’’
(25-50 mm) above pump discharge connection (but below
check valve) to prevent airlocking the pump.
Electrical
Hazardous voltage. Can shock, burn, or
cause death.
When installing, operating, or servicing this
pump, follow safety instructions below.
1.
DO NOT
splice the power cord, submerge electrical cord
plug, or use extension cords.
2.
DO NOT
handle or service pump while it is connected to
power supply.
3.
DO NOT
operate pump unless it is properly grounded.
Power cord is a 3-wire conductor with 3-prong grounding-
type plug. Do not modify cord or plug. Plug pump into a
3-wire, grounded, grounding-type receptacle only. Connect
pump according to all applicable codes.
For automatic operation, plug or wire pump into the automatic
float switch. For continuous operation, plug directly into an
electrical outlet or wire directly into switch box. Connect
pump to its own individual branch circuit with nothing else
on the circuit. See Specifications Chart for fuse or circuit
breaker sizes.
Risk of electrical shock and fire. 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.
Automatic float switch is factory set with a 4’’ tether length. This
tether length can be adjusted to accommodate a variety of
pumping ranges. (See performance graph below). The installer
must ensure that the switch does not become obstructed and
that the range is set so the liquid level remains a minimum of
2’’ above pump suction at the lowest level, and below the basin
inlet pipe at the highest level.
Overloads
An automatic overload protector in the motor will protect
motor from burning out due to overheating/ overloading.
When motor cools down, protector automatically resets.
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.
SERVICE
Pump is permanently lubricated. No oiling or greasing is
required in normal service.
NOTICE:
Do not allow pump to run in a dry sump. It will void
the warranty and may damage the pump.
Hazardous voltage. Can shock, burn, or
cause death.
Before servicing pump, disconnect electrical
power to pump and control switch.
After removing basin cover and necessary discharge piping,
lift pump out of basin.
Risk of electrical shock. Can burn or kill.
Do not lift pump by power cord. See “Cord Lift Warning”.
Place the pump in an area where it can be cleaned thor-
oughly. Remove all scale and deposits on the pump.
Submerge the complete pump in a disinfectant solution
(dilute chlorine bleach) for at least one hour before disas-
sembling the pump.
