Operating Instructions & Parts Manual
General Safety
Information
(Continued)
All wiring should
be performed by a
licensed or certified electrician.
13. For maximum safety, the unit
should be connected to a grounded
circuit equipped with a ground fault
interrupter device.
14. Before installing the pump, have the
electrical outlet checked by a licensed
or certified electrician to make sure
the outlet is properly grounded.
15. Make sure the line voltage and
frequency of electrical current supply
agrees with the motor wiring.
16. Do not attempt repairs to the electric
motor. All repairs to the motor must
be completed at a licensed or certified
electrical motor repair shop.
Do not touch

Modern motors are designed to operate at high
temperatures.
17. Avoid kinking electrical cord and
protect electrical cord from sharp
objects, hot surfaces, oil and
chemicals. Replace or repair damaged
or worn cords immediately.
18. Keep fingers and foreign objects away
from ventilation and other openings.
Do not insert any objects into the
motor.
Risk of electric
shock! Never connect
the green (or green and yellow wire) to a live
terminal!
19. To reduce the risk of electrical shock,
the pump should be plugged directly
into a properly installed and grounded
3-prong grounding type receptacle, as
shown in Figure 1. The green (or green
and yellow) conductor in the cord is
the grounding wire. The motor must
be securely and adequately grounded
for protection against shock.
20. Where a 2-prong is encountered,
replace the plug with a properly
grounded 3-prong receptacle in
accordance with the National Electrical
Code, local codes and ordinances. To
ensure a proper ground, the grounding
means must be tested by a licensed or
certified electrician.
21. Use only 3-wire extension cords that
have a 3-prong, ground type plug, and
3-pole receptacles that accept the
equipment plug.

WATER SUPPLIES
The water supplies illustrated in Figure
26 are possible sources for water. These
water supplies can be divided into two
categories:
SURFACE WATER
Water from a lake, stream, pond and
cistern. This water is usually not fit for
human consumption, but may be suitable
for washing, irrigation or other household
uses.
GROUND WATER
Water found in the water bearing stratum
at various levels beneath the earth. Of
all the fresh water found on earth only 3
percent is found on the surface and 97
percent is underground.
TANKS - CONVENTIONAL STORAGE
The function of the tank is to store a
quantity of water under pressure. When
full, the tank contains approximately
2/3 water and 1/3 compressed air. The
compressed air forces the water out of
the tank when a faucet is opened. An air
volume control automatically replaces
air lost or absorbed into the water. The
usable water, or draw-down capacity, of
the tank is approximately 1/6 of the tanks
total volume when operated on a "20-40"
pressure setting (Figure 2).

TANKS - PRE-CHARGED STORAGE
A pre-charged storage tank has a flexible
bladder or diaphragm that acts as a
barrier between the compressed air and
water. This barrier prevents the air from
being absorbed into the water and allows
the water to be acted on by compressed
air at initially higher than atmospheric
pressures (pre-charged). More usable
water is provided than with a conventional
type tank. Pre-charged tanks are
specified in terms of a conventional tank.
For example, a 20 gallon pre-charged
tank will have the same usable water

or draw-down capacity as a 40 gallon
conventional tank, but the tank is smaller
in size (Figure 2).
PRESSURE SWITCH
The pressure switch provides for
automatic operation. The pump starts
when pressure drops to a cut-in setting.
The pump stops when pressure reaches a
cut-out setting.
PACKAGE SYSTEMS
There are four jet pump/tank assemblies
sold as packages (Chart 1).
WELLS
A new well should be pumped clear of
sand before installing the pump. Sand will
damage the pumping parts and seal. The
draw-down level of the well should not
exceed the maximum rated depth for the
pump. The capacity of the pump will be
reduced and a loss of prime may occur.
