Carefully read and follow all safety instructions in this manual and on pump.

Keep safety labels in good condition.

Replace missing or damaged safety labels.

1.Read this manual carefully. Failure to follow these instructions could cause serious bodily injury and/or property damage.

2.Check your local codes before installing. You must comply with their rules.

3.Vent sewage or septic tank according to local codes.

4.Do not install pump in any location classified as hazardous by National Electrical Code, ANSI/NFPA 70-1990.

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:

5A. Disconnect power to outlet box before unplugging pump.

5B. Take extreme care when changing fuses. Do not stand in water or put your finger in fuse socket.

5C. Do not modify cord and plug. When using cord and plug, plug into a grounded outlet only. When wiring to a system control, connect pump ground lead to system ground.

6.Do not run pump dry. Dry running can overheat pump, (causing burns to anyone handling it) and will void warranty.

7.Pump normally runs hot. To avoid burns when ser- vicing pump, allow it to cool for 20 minutes after shut-down before handling it.

8.In normal service, motor should not need oiling. Motor has been filled at the factory with a special oil.

INSTALLATION

(See Figure 1 for Typical Installation instructions.)

Pump must be level when operating. If motor is tilted, internal start/run switch may overheat and damage motor.

Risk of electrical shock. Can burn or kill. Do not lift pump by power cord. See “Cord Lift Warning” on Page 4. Do not hang pump from discharge pipe or power cord.

1.Install the pump on a solid, level foundation, or in a sump pit constructed of tile, concrete, steel or plas- tic. The recommended minimum diameter of the sump pit is 18" (46cm) diameter and the minimum recommended depth is 30" (76cm). Check local codes for approved materials.

NOTICE: Pump should not be installed on clay, earth or sand surfaces. Clean the area around the pump of small stones and gravel which could clog the pump. Keep the pump inlet screen clear.

2.Thread a 2” discharge pipe into the pump 2” NPT discharge port. Be careful to avoid stripping or cross- ing threads.

Piping – Effluent Applications (3/4" or Less Solids)

Piping must be 1-1/2" minimum to carry volume of pump discharge. Check local codes to determine if a check valve is required in your system. In cold climates, check valves are not used to prevent effluent from freez- ing in piping.
