Operating Instructions and Parts Manual
General Safety
Information
(Continued)
Do not touch an
operating motor.
Modern motors are designed to operate at
high temperatures.
17. Avoid kinking electrical cord and
protect from sharp objects, hot sur-
faces, oil and chemicals. Replace or
repair damaged or worn cords
immediately.
Disconnect power
and release all pres-
sure from the system before attempting
to install, service, relocate or perform any
maintenance. Lock the power disconnect
in the open position. Tag the power dis-
connect to prevent unexpected applica-
tion of power.
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 con-
nect 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 ground-
ing 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 ordi-
nances. To ensure a proper ground,
the grounding means must be test-
ed by a licensed or certified electri-
cian.
21. Use only 3-wire extension cords that
have a 3-prong, grounding type
plug, and 3-pole receptacles that
accept the equipment plug.

22. Use wire of adequate size to mini-
mize voltage drop at the motor.
Do not handle
pump or pump
motor with wet hands, when standing
on a wet or damp surface or when
standing in water. Fatal electrical
shock could occur.
Pump motor is
equipped with an
automatic resetting thermal protector and
may restart unexpectedly. Protector trip-
ping is an indication of motor overloading
because of operating pump at low heads
(low discharge restriction), excessively
high or low voltage, inadequate wiring,
incorrect motor connections or defective
motor or pump.

WATER SUPPLIES
The water supplies illustrated in Figure
12 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 suit-
able for washing, irrigation or other
household uses.
GROUND WATER
Water found in the water bearing stra-
tum 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 approxi-
mately 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 auto-

matically replaces air lost or absorbed
into the water. The usable water, or
drawdown capacity, of the tank is
approximately 1/6 of the tanks total
volume when operated on a "20-40"
pressure setting (Figure 2).

TANKS - PRECHARGED STORAGE
A precharged storage tank has a flexi-
ble 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 (precharged).
More usable water is provided than
with a conventional type tank.
Precharged tanks are specified in terms
of a conventional tank. For example, a
20 gallon precharged tank will have
the same usable water or drawdown
capacity as a 40 gallon conventional
tank, but the tank is smaller in size
(Figure 2).
PRESSURE SWITCH
The pressure switch provides for auto-
matic operation. The pump starts
when pressure drops to a cut-in setting.
The pump stops when pressure reaches
a cut-out setting.
