GENERAL SAFETY INFORMATION (CONTINUED)
13. Make sure the line voltage and frequency of electrical current supply
agrees with the motor wiring.
14. 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 an operating motor. Modern
motors are designed to operate at high
temperatures.
15. Avoid kinking electrical cord and protect electrical cord from sharp
objects, hot surfaces, oil and chemicals. Replace damaged or worn
cords immediately.
16. 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!
17. Use wire of adequate size to minimize 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 will occur.
Pump motor is equipped with an automatic
resetting thermal protector and may restart
unexpectedly. Protector tripping is an indication of motor overheating
because of operating pump at low heads (low discharge restriction),
excessively high or low voltage, inadequate wiring, incorrect motor
connections,excessive surrounding air temperature, inadequate
ventilation, and/or defective motor or pump.
PRE-INSTALLATION
WATER SUPPLIES
The water supplies illustrated in Figure 16 (on page 10) 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 1).
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 1).
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.
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.
INSTALLATION
LOCATION
Select a location as close to the water supply as possible.
Be sure to comply with any state or local codes regarding the placement
of the pump. The equipment must be protected from the elements. A
basement or heated pump house is a good location. Make sure the
pump has proper ventilation. The temperature surrounding the pump is
not to exceed 100° F (38°C) or nuisance tripping of the motor overload
may occur.
This pump is designed for indoor installation
only. Failure to install indoors will significantly
increase the risk of injury or death from electrical shock.
