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 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 12, on page 9, are
possible sources for water. These water supplies can be divided
into two categories:
SURFACE WATER
Water from a lake, stream, pond and/ or 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. Then 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 drawdown capacity, of the tank is approximately
1/6 of the tanks total volume when operated on a 20 lb.-40 lb.
pressure setting (Figure 1).
TANKS - PRECHARGED STORAGE
A precharged 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 (precharged). More usable
SWS Systems
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 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.
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.
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.
PIPING
Piping may be copper, steel, rigid PVC plastic or flexible
polyethylene plastic.
Flexible pipe is NOT recommended on suction pipe
(inlet pipe).
The pipe must be clean and free of rust or scale. Use a pipe joint
compound on the male threads of the metal pipe. Plumber’s seal
tape should be used with plastic threads. All connections must
be air tight to insure normal operation.
Slope all inlet piping upwards towards the pump to prevent
trapping air. Unions or hose couplings can be installed near
pump to facilitate removal for servicing or storage. A rubber
hose installed between the water system and the house piping
will reduce the noise transmitted to the house.
PIPE SIZES
Long horizontal pipe runs and an abundance of fittings and
couplers decrease water pressure due to friction loss. See Chart
2 on page 3 to determine the proper pipe size.
