Pump Installation - STA-RITE AN Series Owner's Manual

PUMP INSTALLATION

Install the pump as shown in Figures 1 or 2. It is impor-
tant that a foot valve be used, or that a check valve be
installed in the horizontal line as near the pump as pos-
sible. A 4" long nipple should be installed in the 1" suc-
tion tapping of the pump. If pump is tank mounted, the
pump discharge is already piped to the tank, and is
ready to be piped to the house service. A base mount-
ed pump can be connected to a vertical tank by means
of a pump-to-tank fittings kit (available from your deal-
er) and necessary piping. A gate valve should be
installed in the line between the pump and tank.
Relief valve must be capable of passing full pump flow
at 75 PSI.
Horizontal Piping
In a horizontal offset installation, elbows and horizontal
piping must be added to complete installation. Be sure
to pitch the pipe up to the pump from the well, in order
to avoid air pockets. When all piping is correctly posi-
tioned, tighten the bolts in the well seal, making sure
the well seal is firmly seated in the casing.
Run the suction piping direct from the jet to the well. If
the suction line has a long horizontal run – (50 ft.) a foot
valve is necessary. A tee with a plug near the pump is
desirable to fill the suction line for the initial prime.

Pressure Tanks and Piping
Several types of tank installations can be used with this
pump. In the case of an assembled water system, the
pump is mounted on a pressure tank, and only requires
connection to the house piping. All connections
between the pump and tank are made at the factory.
The tank serves two functions. It provides a reservoir of
water, some of which can be drawn through the house
fixture before the pump must start, and it maintains a
cushion of air under pressure.
When a horizontal 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 installa-
tion and operation.
When Sta-Rite Con-Aire
control is necessary. This tank contains a permanent
precharge of air.
