sonal injury, death or major property damage if ignored.
warns about hazards that can cause serious per-
sonal injury, death or major property damage if ignored.
warns about hazards that will or can cause
minor personal injury or property damage if ignored.
The word NOTICE indicates special instructions which are
important but not related to hazards.
1. To avoid serious injury and/or property damage, read these
rules and instructions carefully.
2. Check your local codes before installing. You must comply
with their rules.
3. Vent sewage or septic tank according to local codes.
4. Pump normally runs hot. To avoid burns when servicing
pump, allow it to cool for 20 minutes after shut-down
before handling it.
5. Do not run pump dry. Dry running can overheat pump and
will void warranty.
6. Pump is permanently lubricated. No oiling or greasing is
required in normal operation. For overhaul, see instructions
under "Service".
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:
7A. Ground pump according to all applicable codes and ordi-
nances.
7B. Disconnect power to outlet box or circuit breakers before
servicing
7C. 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:
7D. Do not modify cord and plug unless removing plug com-
pletely and wiring pump directly into switch box or con-
troller. When using cord and plug, plug into a grounded
outlet only. When wiring to a system control, connect
pump ground lead to system ground.
Three Phase Pumps:
7E. Three phase pumps are intended for permanent connection
only. Provide strain relief at control box for power supply
cord connection to box.
INSTALLATION
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 458 mm (18") in diameter and
762 mm (30") deep.

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 51 mm (2") diameter.
The rate of flow in the discharge pipe must keep any solids pre-
sent in suspension in the fluid. To meet minimum flow require-
ments of 61 cm/sec (2 feet per second) in discharge line, size
pipe as follows:
A Pipe Size Of: Will Handle a Flow Rate Of:
51 mm (2”) 79.5 L/M (21 GPM)
63.5 mm (2-1/2”) 113.5 L/M (30 GPM)
76 mm (3”) 182 L/M (48 GPM)
Use a 51 mm (2") 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.
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 5 mm (3/16") hole in discharge pipe about 25-50 mm
(1–2") 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 remove grounding prong from plug or modify
plug. Power cord on 1-phase units is a 3-wire conductor with
a 3-prong grounded plug. Plug pump into a 3-wire, ground-
ed, grounding-type receptacle. If there is no 3-wire grounded
receptacle to plug into, remove plug completely and wire
pump directly into terminal block in automatic float or
duplex controller box. Connect pump according to all applic-
able codes.
For automatic operation, plug or wire pump into an automatic
float switch or duplex controller. For continuous operation, plug
directly into an electrical outlet or wire directly into switch box.
Connect pump to its own circuit with nothing else on the cir-
cuit. 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.

Operation and Installation
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, 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.
Pump is permanently lubricated. No oiling or greasing is
required in normal service.
SERVICE
General
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.
Place pump in an area where it can be cleaned thoroughly.
Remove all scale and deposits on pump.
Submerge pump in disinfectant (chlorox or chlorine) for at least
one hour before disassembling pump.
The pump motor housing contains a special lubricating oil.
Keep oil clean and free of water at all times.
NOTICE: Whenever motor housing is being removed for ser-
vice, remove oil and replace with new oil at reassembly. Use
only oil listed in parts list (Part No. U197-8A). When filling
with new oil, DO NOT overfill. To allow room for expansion,
oil level with cold motor should be about 6 mm (1/4") above top
of motor assembly.
