Failure to follow these Rules and Instructions could
cause serious bodily injury, and/or property damage.
Check your local electrical wiring codes before installation. 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.
BE SURE your pump installation
meets all local
plumbing,
pump and well codes.
8.
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 mechanical operation
of the pump.

When Captive Air* Tanks are used, no air volume control is necessary. This tank is precharged
with air at the
factory.
When a Standard Tank is used, an air volume control
adds air to the tank when it is needed. See instructions
included with Air Volume Control for details on installation and operation.
On well point installations
where the horizontal
piping is more than 25 feet, a check valve should be installed as shown in Figure 3, Page 4.

When the pump is offset more than 25 feet from the
well, horizontal

in size to
reduce friction losses. In no case should the offset piping be smaller than the suction tapping of the pump.

When used with a Captive Air* Tank, the precharge

See the Captive Air* Tank instructions for details.
Impeller
and Jet
The impeller of the pump rotates with the motor shaft,
causing the water to fly out from its rim by centrifugal
force. The rotation of the impeller creates a partial vacuum which pulls in more water. Part of the water is diverted back to the jet where it passes through
the
nozzle and venturi, reinforcing
the vacuum to draw in
more water and delivering
it at a high velocity to the
impeller.
Because of the shallow setting, the partial vacuum created by the pump is sufficient
to pull water to the
pump, therefore, the jet assembly is attached directly
to the pump.

Discharge
When the pump is set a distance
from the house or
point of water use, the discharge pipe size should be
Increased to reduce pressure losses caused by friction.

Both figures arc for sea level - the maximum

with the elevation at the approximate
rate of 1 foot per

Thus, if the lift is 17 feet and
Power
In some areas and with some installations,
an emergency power supply to guard against power failure is a
good idea. If you install an engine-generator
set for
emergency
backup power for your pump, supply the
generator
set manufacturer
with the nameplate
data
from the pump motor. He will then be able to provide
a generator
of the correct size to power your pump.
Also, be sure to add the load from any other accessories
(such as lights) that may be on the same circuit.
A Shallow well jet pump can be installed on a dug well,
drilled well or with a driven point. SEARS shallow well jet
pumps have a built-in check valve. In a dug or cased well,
a foot valve and strainer is recommended
and should be
installed 5 to 10 feet below the lowest level to which the
water will drop while pump is operating (pumping water
level), See Figure 3, Page 4. Your well driller can furnish
this information. The strainer should not be too close to
the bottom, or sediment may clog it. Before installing foot
valve, check to see that it works freely.
When using a foot valve, a priming
shown in Figure 1, is recommended.

CRAFTSMAN Captive Air* Tanks are precharged
with
air at the factory. Check the tank Owner's Manual to
find if air charge needs adjustment.
Your pump requires 30 pounds for proper operation.
The jet pump can also be mounted
on standard horizontal tanks. A kit consisting of all necessary piping, elbows, and other fittings, is furnished with the tank for

WELL
In some localities
well water contains
gases which
must be allowed to escape before the water is used.
This can be done as shown in Figure 8.
A good way of delivering gas-free water is to suspend
a pipe, closed at the bottom and open at the top, surrounding
the suction pipe, Figure 8. Since the gases
rise in the well casing, the water sucked down through
the pipe and into the suction pipe is free of gas. It is
imperative
that this type of well be vented to the outside of any enclosure.
