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.
