INSTALLATION
Risk of electrical shock. Can burn or kill.
Do not lift pump by power cord. See "Cord Lift Warning" on
Page 5.
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 a sewage system, pipe must be capable of
handling semi-solids of at least 2'' (51mm) diameter.
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:
2'' (51 mm)
2-1/2'' (64 mm)
3'' (76 mm)
In a sewage system use a 2'' (51 mm) min. 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.
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.
Will Handle a Flow Rate Of:
21 GPM (79.5 L/M)
30 GPM (113.5 L/M)
48 GPM (182 L/M)
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.
Wire pump directly into grounded terminal block in auto-
matic float or pump controller box. Power cord on 1-phase
units is a 3-wire conductor with 3-prong grounding-type
plug. Do not modify cord or plug. When using with plug-in
receptacle, plug pump into a 3-wire, grounded, ground-
ing-type receptacle only. Connect pump according to all
applicable codes.
For automatic operation, plug or wire pump into an automatic
float switch or pump controller. 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
(Page 2) 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 incom-
ing power supply exactly. Install pump according to all
electrical codes that apply.
Models with an automatic float switch are factory set with a
4'' tether length. This tether length can be adjusted to accom-
modate a variety of pumping ranges. (See performance graph,
Page 4). 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 - Single Phase
In single-phase units, an automatic overload protector in the
motor will protect motor from burning out due to over heating/
overloading. When motor cools down, protector automatically
resets 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.
