INTRODUCTION

Please read our instructions before installing and using
your pump. This will help you obtain the full benefits
of the quality and convenience built into this equip-
ment. It will also help you avoid any needless service
expense resulting from causes beyond our control
which are not covered by our warranty.

1. Read the Owners Manual and Rules for Safe

Operation and Installation Instructions carefully.
Failure to follow these Rules and Instructions could
cause serious bodily injury, and/or property dam-
age.

2. Check your local electrical wiring codes before in-

stallation. If your local codes are not followed, your
pump will not work to its full rated capacity and
could present a fire hazard. If in doubt, contact your
local power company.

3.

BE SURE

your pump installation meets all local

plumbing, pump and well codes.

4. While installing your pump, always keep the well

covered to prevent leaves and foreign matter from
falling into the well, contaminating the water
and/or causing possible serious damage to the me-
chanical operation of the pump.

5. Always test the water from well for purity before

using. Check with local health department for test-
ing procedure.

6. Before installing or servicing your pump, 

BE SURE

pump power source is disconnected.

7.

BE SURE

your pump electrical circuit is properly

grounded.

8. Complete pump and piping system MUST be pro-

tected against below freezing temperature.
Allowing the pump or piping to freeze could cause
severe damage and voids the Warranty.

9.

BE SURE

the line voltage and frequency of the elec-

trical current supply agree with the motor wiring
as shown on motor nameplate.

10. The correct fusing and wiring sizing is essential to

proper motor operation. Use recommended fusing
and wire size data in the manual (Page 6).

11. Pump water only with this pump.
12. Periodically inspect pump and system components.
13. Relief valve must be capable of passing full pump

flow at 75 PSI.

Pump body may explode if used as a

booster pump unless relief valve capable of pass-
ing full pump flow at 75 PSI (517 kPa) is installed.

Motor normally operates at high temper-

ature and will be too hot to touch. It is protected from
heat damage during operation by an automatic internal
cutoff switch. Before handling pump or motor, stop
motor and allow it to cool for 20 minutes.
