Hazardous voltage. Can shock, burn, or
cause death. During operation the pump is in water. To
avoid fatal shocks, proceed as follows if pump needs
servicing:
8A. Ground pump according to all applicable codes and ordi-
nances.
8B. Disconnect power to outlet box or circuit breakers before
servicing.
8C. To reduce risk of electric shock, take care when changing
fuses or resetting circuit breakers. Do not stand in water
when working on control box or with circuit breakers.
Single Phase Pumps:
8D. When using cord and plug, plug into a grounded outlet with
it’s own individual branch circuit. When wiring to a system
control, connect pump ground lead to system ground.
Three Phase Pumps:
Risk of electrical shock. Do not remove cord
or strain relief. Do not connect conduit to pump.
8E. Three phase pumps are intended for permanent
connection only. Provide strain relief at control box for
power supply cord connection to box. All control compo-
nents must be UL listed and suitable for end use
application. Only qualified personnel should install and
service the pump and associated control equipment.
INSTALLATION

SAFETY INSTRUCTIONS

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 feet 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 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.
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 ground-
ing-type plug. Do not modify cord or plug. When using
with plug-in receptacle, plug pump into a 3-wire, ground-
ed, grounding-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 chart below 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.
