Safety Information and Introduction

WARNING

Before handling this pump, always disconnect the power first.

This pump should only be serviced by a qualified person or a factory trained person.

CAUTION

This instruction manual includes necessary items for installation, operation

and

maintenance. Read this manual carefully to ensure correct installation,

operation and maintenance.

Be sure to keep this instruction manual on hand for future reference.

EBARA’s Dominator sewage pumps are designed for reliable pumping of waste water with suspended

solids up to 2" in diameter. Maximum fluid temperature

40°C, 104°F

(possible intermittent duty to 60°C,140°F when totally submersed).

Stainless steel construction is ideal for residential, commercial, and industrial applications. Dual seals are a standard feature enhancing the rugged, high service factor motor design.

The EBARA Dominator is superior in dependability and efficiency. High quality components are stronger, dimensionally consistent, and lighter weight compared to conventional cast iron parts.

EBARA stainless steel is engineered for the

professional and built for lasting performance and value.

Electrical Installation

Electrical service for any sump pump installation must be grounded and separately fused or breakered directly from the entrance box with a single grounding type receptacle. You should never touch a sump pump or discharge piping while the pump is connected to electrical power and water is present. The pump should be disconnected from the electrical source before handling in all cases.

Discharge Piping Installation

To assure the maximum performance from your pump, the discharge pipe size and piping fittings should not be smaller than the discharge port of the pump. Smaller pipe will add to friction losses and reduce the capacity of the pump.

CAUTION

Call an electrician when in doubt. Improper installation can result in harm to people and/or damage to equipment.

Electrical information – Single Phase

• Use a separate 15 amp circuit breaker or 15 amp fuse block with the pump.

• Do not use an extension cord with the pump.

• Do not cut off the ground pin or use an adapter fitting.

• Do not work on the pump or switch until any or all power cords are unplugged.

• Failure to follow these guidelines my cause severe damage to the pump and will void warranty.

IMPORTANT INSTRUCTIONS BEFORE INSTALLATION

Failure to follow these instructions may cause serious bodily injury and/or property damage.

• Pumps are 115 V, 60Hz or 230V 60Hz.

• Please check the voltage rating on the pump nameplate prior to installation.

WARNING

Risk of electric shock

This pump is supplied with a grounding conductor or a groundingtype attachment plug. To reduce the risk of electric shock, be certain that it is connected only to a properly grounded, groundingtype receptacle.

Safety Information and Introduction

(continued)

Normally accepted materials are galvanized pipe, rigid plastic pipe or

acceptable

flexible pipe or hose.

Where the discharge pipe is long, a check valve is often employed to prevent the water from flowing back into the sump when the pump turns off. If the discharge is directed into a sanitary sewer, a suitable anti-siphon device or a free flow check valve should be inserted in the line to prevent backflow into the pit.

Pump Installation

When the sump, electrical and discharge plumbing installation is complete and ready for the pump, clean all solid debris from the pit. Complete the plumbing connection to the pump and then plug the pump into the electrical outlet. A few extra minutes to test the sump pump installation are now in order.

Fill the sump with water, note the turn on and turn off level of the pump, and the pumping cycle. This will allow you to calculate the approximate discharge flow of the pump system. If everything is operating properly, install the sump cover.
