Introduction

This pump has been carefully packaged, inspected and tested to ensure safe operation and delivery. Before installing the pump, check to

see if any damage has occurred to the pump from rough handling. Notify the dealer from whom you purchased the pump if any damage

has occurred.

This sewage pump is suitable for pumping sewage, effluent, wastewater, groundwater and other non-explosive, non-corrosive liquids with

up to 2" (51 mm) solids. The pump includes a wide angle float switch that turns the pump on and off as the fluid level rises and falls.

Safety Instructions

The following safety rules should be followed to avoid serious injury or property damage:

Always remove the plug from the electrical outlet before servicing this pump.

1. Check with your local electrical and plumbing codes to ensure you comply with the regulations. These codes have been designed

with your safety in mind. Be sure to comply with them.

2. We recommend that a separate circuit be led from the home electrical distribution panel and properly protected with a fuse or a

circuit breaker. We also recommend that a ground fault circuit be used. Consult a licensed electrician for all wiring

3. Do not stand in water when connecting or disconnecting power cord from outlet.

4. This product should be connected to a three prong grounded outlet equipped with a ground fault circuit interrupter.

5. Do not pump flammable liquids with this pump as an explosion or fire could result.

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

7. Do not run this pump dry. Running your pump without water will damage the mechanical seal, reduce the life of the pump and void

the warranty.

8. Do not touch metal motor housing for at least 30 minutes after pump has operated. A severe burn will result if pump is not allowed to

cool. Do not lift the pump by the electrical cord.

9. This product does not require lubrication. A special oil has been put into the motor housing at the factory for lifetime lubrication of the

bearings. Use of any other oil can cause damage and void the warranty.

Installation Instructions

1. Install pump on a hard, level surface (cement, asphalt, etc.). Never place pump directly on earth, clay or gravel surfaces.

2. Install pump in a basin of at least 16 inches (405 mm) diameter and 24 inches (610 mm) depth.
