1/2 HP CONVERTIBLE PUMPS (Table 1)
The factory-assembled nozzle and venturi configuration is for shallow well use
when the injector is bolted to the pump case.
The factory-assembled nozzle and venturi configuration is also used for medium
deep well (20 to 40 ft.) when the injector is mounted in the well.
For deeper pumping depths (20 to 90 ft.) remove the factory venturi and install
the loose venturi supplied in this kit. The injector is now set up for deep well use,
when the injector is mounted in the well.

Pump Location: Install the pump in a clean, dry, ventilated location that provides
adequate room for servicing and protection from freezing temperatures. It
should be bolted to a good foundation (preferably concrete) and provided with
24728500
adequate drainage. Locating the pump as close as possible to the water source
will reduce the friction in the suction pipe and ensure maximum capacities.
Suction and Pressure Pipe: Only new, clean 1-1/4" pipe or hose should be
used. If the pump is installed any appreciable distance away from the source of
water, the suction pipe should be increased to 1-1/2". Horizontal lengths of pipe
must gradually slope upwards from the source of water to the pump to avoid
air pockets in the line. Thread compound should be used on all pipe joints and
24728500
connections should be thoroughly tightened. Install a foot valve and check
its operation because a leak will prevent proper operation of the system. Make
sure the foot valve is located so that it will be submerged at all times. If the
well cannot supply as much water as the pump can draw, install a tailpipe up
to 30 feet long between the injector and the foot valve. As the well draws down
under heavy demand, the pump's capacity will be reduced, and the level will
46899400
not go below the foot valve, which would cause the pump to lose its prime. If a
sandpoint or driven well is used, install a check valve next to the pump suction
instead of the foot valve (Figure 8). All installations must have a foot valve or
a check valve in the suction pipe.
Pump to Tank Fittings: The discharge pipe from the pump to the tank should
be as short and direct as possible and should be the same size as that of the
pump discharge tapping. A check valve should never be installed between the
pump and the tank.
Service Line: Connect the service line as shown in Figures 7 - 10. The size of the
service line required is governed entirely by the amount of water needed and the
length of the pipe. The pipe selected should be large enough so that the friction
loss (determined from Table 5, Friction Loss) will never exceed 20 ft. (6m) head.
WARNING - ELECTRICAL PRECAUTIONS
All wiring, electrical connections, and system grounding must comply with
the National Electrical Code (NEC) and with any local codes and ordinances.
Employ a licensed electrician.
WARNING - RISK OF ELECTRICAL SHOCK
Wiring: Use an electrician to wire and connect the electrical service to the pump.
The pressure switch is wired to the motor at the factory and the voltage for which
the motor is wired is indicated by a sticker on the back of the motor. Make sure
the motor is wired for the same voltage as the power supply. Refer to the motor
nameplate or inside terminal cover for voltage changing instructions. The power
lines should be connected to the pressure switch terminals marked L1 and L2
(Figure 6). It is recommended that a separate circuit be led from the distribution
panel to the pump unit. A ground fault circuit interrupter (GFCI) protected circuit
should be used for all electrical devices operating near water. Install a proper
fused disconnect switch in the line and make certain the wiring is adequately
sized and well insulated. Undersized wire between the motor and the power
24728800
source will adversely limit the starting and load carrying abilities of the
motor. Minimum wire sizes for motor branch circuits are recommended in Table
3. For added safety, ground the pump and motor to the well casing (if metal) or
the ground in the distribution panel.
Pressure Gauge: If a pressure gauge is supplied with the pump or if you wish
to install a pressure gauge, it should be installed into the 1/4" NPT hole on the
front of the casing directly beside the discharge opening.

Air Volume Control: If a non-diaphragm tank is used in the pressure system,
an air volume control must be used to maintain an air cushion in the pressure
tank. If not, air in the tank will gradually be absorbed by water, causing the tank
to water log, and the pump to short cycle. This greatly shortens the life of the
motor. An air volume control will provide the right air/water ratio and prevent
24730000
water logging. Refer to the pressure tank owner's manual for instructions.
Pressure Relief Valve: A high pressure safety relief valve is recommended at
some point in the water system. Ensure its location is near the discharge of the
pump, in an area with adequate drainage. Be sure to direct the valve so that any
water flow could not spray toward any electrical devices.
