Electrical / Operation / Service

Use a 2" (5.1 cm) swing check valve in pump discharge to prevent backflow of liquid into sump basin. 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 the discharge pipe angled more than 45° above the horizontal. Do not install check valve in a vertical position as solids may settle in valve and prevent the check valve from opening on startup.

Drill a 3/16" (4.7mm) hole in discharge pipe about 1"-2" (2.5 - 5.1cm) 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 listed below.

1.DO NOT splice the electrical power cord.

2.DO NOT allow electrical cord plug to be submerged.

3.DO NOT use extension cords. They are a fire hazard and can reduce voltage sufficiently to prevent pump- ing and/or damage motor.

4.DO NOT handle or service pump while it is connected to power supply.

5.DO NOT remove grounding prong from plug or modify plug.To protect against electrical shock, the power cord is a three-wire conductor and includes a 3-prong grounded plug. Plug pump into a 3-wire, grounded, grounding-type receptacle. Connect pump according to electrical codes that apply.

For automatic operation, plug or wire pump into an automatic float switch or pump controller. Pump will run continuously when plugged directly into an electrical outlet. Connect or wire pump to an individual branch circuit with no other outlets or equipment in the circuit. Size fuses or circuit breakers according to Fuse Size Chart at right.

Risk of electrical shock and fire. Can cause severe personal injury, property damage or death. Be sure that power supply information (Voltage/ Hertz/Phase) on pump motor nameplate matches incom- ing 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 pro- tect motor from burning out due to overheating/over- loading. When motor cools down, overload 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.

GENERAL

Hazardous voltage. Can shock, burn, or cause death. Before removing pump from basin for ser- vice, always disconnect electrical power to pump and control switch.

Risk of electrical shock. Can burn or kill. Do not lift pump by the power cord.

Submerge pump in a disinfectant solution (chlorox or chlorine) for at least one hour before disassembling pump.

The pump motor contains a special lubricating oil which should be kept clean and free of water at all times.
