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

ordinances.

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

completely 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.

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.
