2.Install discharge plumbing. When using rigid pipe, use plastic pipe. Wrap thread with Teflon tape or use Plasto-Joint Stik*. Screw pipe into discharge fitting hand tight +1 – 1-1⁄2 turns.

NOTE: Do not use ordinary pipe joint compound on plas- tic pipe. Pipe joint compound can attack plastics.

3.To reduce motor noise and vibrations, a short length of rubber hose (1-7⁄8" I.D., e.g. radiator hose) can be con- nected into discharge line near pump using suitable clamps.

4.Install an in-line check valve to prevent flow back- wards through pump when pump shuts off.

5.Thread vent pipe into 1-1⁄2" NPT black vent fitting in basin cover. Pipe should not extend into basin. Connect vent pipe to sewer vent system.

6.Power Supply: Pump is designed for 115 V., 60 Hz., operation and requires a minimum 15 amp individual branch circuit. Both pump and switch are supplied with 3-wire cord sets with grounding-type plugs. Switch plug is inserted directly into outlet and pump plug inserts into opposite end of switch plug.

Hazardous Voltage. Pump should always be electrically grounded to a suitable electrical ground such as a grounded water pipe or a properly grounded metallic raceway or ground wire system. Do not cut off round ground pin.

7.If pump discharge line is exposed to outside sub-freez- ing atmosphere, portions of line exposed must be installed so any water remaining in pipe will drain to the outfall by gravity. Failure to do this can cause water trapped in discharge to freeze which could result in damage to pump.

8.After piping and check valve have been installed, unit is ready for operation.

9.Check operation by filling sump with water and observing pump operation through one complete cycle.

Risk of flooding. Failure to make this opera- tional check may lead to improper operation, premature failure, and flooding.

MAINTENANCE

Risk of electric shock. Make certain that the pump is unplugged before attempting to service or remove any component.

Risk of electric shock. Do not handle a pump or pump motor with wet hands or when standing on wet or damp surface, or in water.

1.Keep pump inlet screen clear.

2.Shaft seal depends on water for lubrication. Do not operate pump unless it is submerged in water as seal may be damaged if allowed to run dry.

3.Motor is equipped with automatic reset thermal protec- tor. If temperature in motor should rise unduly, switch will cut off all power before damage can be done to motor. When motor has cooled sufficiently, switch will reset automatically and restart motor. If protector trips repeatedly, pump should be removed and checked for cause of difficulty. Low voltage, long extension cords, clogged impeller, very low head or lift, etc., could cause cycling. Refer to Trouble shooting Guide on Page 6 for additional information.

4.Periodically inspect pump, system components, and sump for debris and foreign objects. Keep sump free of all refuse. Perform routine maintenance as required.
