INTRODUCTION

Please read our instructions before installing and using
your Deep Well Jet Pump. This will help you obtain the
full benefits of the quality and convenience built into
this equipment. It will also help you avoid any needless
service expense resulting from causes beyond our con-
trol which are not covered by our warranty.

Carefully read and follow all safety instructions in this
manual or on pump

This is the safety alert symbol. When you see this

symbol on your pump or in this manual, look for

one of the following signal words and be alert to the
potential for personal injury!

The word 

NOTICE 

indicates special instructions

which are important but not related to hazards.

1. To avoid risk of serious bodily injury and property

damage, read safety instructions carefully before in-
stalling pump.

2. Follow local and/or national plumbing and electri-

cal codes when installing pump.

3. Keep well covered while installing pump to prevent

leaves and other debris from falling into well, con-
taminating well and possibly damaging pump.

4. Protect pump and piping system from freezing.

Allowing pump or water system to freeze could
severely damage pump and voids warranty.

To  avoid serious injury and equip-

ment damage, limit system pressure to 100
pounds per square inch (PSI) or below at all
times. Over-pressure can cause tank blowup; in-

ume at 100 PSI.

5. With a new well, test well for purity before use.

Consult local Health Department for procedure.

ing lug on motor to a grounded lead in the service
panel.

8. Line voltage and frequency of electrical power sup-

ply must agree with motor nameplate.

in owner’s manual can cause overheating, possible
fires, and will void warranty.
