Operating Instructions And Parts Manual

supplied with a grounding conductor and grounding type attachment plug. Use a grounded receptacle to reduce the risk of fatal electrical shock.

Never cut off the round grounding prong. Cutting the cord or plug will void the warranty and make the pump inoperable.

2.This pump is only for use on 120 Volt (single-phase), 60 hz, 15 amp service and is equipped with a 3- conductor cord and 3-prong, grounding type plug. Insert the float switch cord plug directly into a 120 volt outlet.

4.Fill sump with water. The pump will start automatically when the water has filled the sump to a depth of approximately 13“. The pump will stop when the water depth is approximately 7”. The pump will recycle thereafter as required.

5.Do not operate the pump unless it is submerged in water. Dry running causes pump failure.

6.The motor is equipped with an automatic reset thermal protector.

7.While the pump is draining the pit, verify that the discharge piping is carrying the water to a point several feet away from the foundation.

8.If pump discharge line is exposed to freezing temperature, the exposed line must be pitched to drain.

Trapped water will freeze and damage the pump.

Maintenance

Always disconnect the electrical supply before attempting to install, service, relocate or

perform any maintenance. If the power source is out of sight, lock and tag in

the open (off) position to prevent unexpected power application. Failure to do so could result in fatal electrical shock. Only qualified electricians should repair this unit. Improper repair could result in fatal electrical shock.

1.Let the pump cool for a minimum of two hours before servicing because the pump contains hot oil under pressure and the motor is hot.

2.Disassembly of the motor prior to expiration of warranty will void the warranty. If repairs are required, see troubleshooting chart.

4.Inlet should be kept clean and free of all foreign objects and inspect annually. A clogged inlet will damage pump.

5.Pump should be checked monthly for proper operation.

This pump contains dielectric oil for

cooling. This oil can be harmful to the environment. Check the state environmental laws before disposing this oil.
