INTRODUCTION
Waterous E500 Motor Pumps are gear driven centrifu-
gal pumps powered by a three-cylinder, diesel Kubota
engine.
An optional remotely mountable instrument panel and
a priming system consisting of either a Waterous'
hand or electric primer are available.
The model numbers below define the different pump
designations.

INSTALLATION
1.
Battery cable - The correct wire gage depends on
the length of cable needed. Use the following
chart to determine what size battery cable to use:
These instructions are to be used for placing the
pumping unit into operation, maintenance and repair
of the pump. Refer to the Kubota Operation and Main-
tenance instructions for maintenance of the engine.
Major repairs of the engine can be taken care of by an
authorized Kubota dealership.
2.
Fuel line - Route the fuel line from the fuel tank
(not supplied by Waterous) such that low pockets
in which water could accumulate and freeze, and
high pockets where fuel vapors could collect and
restrict the flow of liquid fuel (vapor lock) are elimi-
nated. Avoid potential rubbing and high heat
areas, and use adequate connectors and re-
straints to avoid accidental disconnecting of fuel
lines.
3.
The maximum vertical lift the fuel pump can
achieve is two feet (610 mm) with any length fuel
line. On diesel engines, be sure the return line
reaches the bottom of the fuel tank to prevent air
bubbles (see pump dimensional drawing for fuel
return outlet on engine).
4.
Mounting - Kubota recommends an isolation
mount for the engine to minimize vibration.
5.
Air Flow - keep the front of the radiator unob-
structed to allow for adequate air flow. The fan
pulls air across the radiator and then pushes the
outside air over the engine.
6.
Priming system - See optional priming pump in-
struction, F-1031, Section 3006, Priming System
Installation Instructions.
7.
Emission label - If emission control label, located
on engine cylinder head, is not visible on engine
after installation, the loose label provided must be
applied such that it is visible when engine is ac-
cessed, per EPA/CARB requirements.
