INSTALLATION (CON'T)
SHALLOW WELL PUMP WITH PRECHARGED STORAGE
TANK
1. Shut off the power to the pump.
2. Open the faucet nearest the tank and allow all water to drain
from the tank.
3. Measure the tank precharge at the valve stem using a tire
pressure gauge.
4. If necessary, precharge with an air pump to 28 - 30 psi on
1/2, 3/4 and 1 HP pumps.
5. Slope the horizontal pipes upward toward the pump to
prevent trapping air. If the horizontal distance exceeds 25
feet, see Chart 2 on page 3 for the recommended pipe size.
ELECTRICAL
Risk of electrical shock. This pump is designed for
indoor installation only.
The voltage of power supply must match the voltage of the
pump. The motors can be converted to 115/230 volts by turning
the voltage selector to the desired voltage (See Figure 6). Use
a needle nose pliers to pull the selector out approximately 1/4”,
rotate and then reinsert in correct position.
Select the proper size wire and fuse (Chart 3). Time delay
fuses are recommended over standard fuses for motor circuit
protection. All pump motors have built-in automatic overload
protection that will prevent damage to the motor due to
overheating.
Do NOT connect to electric power supply until unit is
permanently grounded. Connect ground wire to approved
ground then connect terminal provided.
A metal underground water pipe or well casing at least 10 feet
long makes the best ground electrode. If plastic pipe or insulated
fittings are used, run a wire directly to the metal well casing or
use a ground electrode furnished by the power company.
There is only one proper ground terminal on the unit. The
terminal(s) is located under the pressure switch cover, is painted
green and is identified as GRD. The ground connection must be
made at this terminal (Figure 7). The ground conductor must not
be smaller than the circuit conductors supplying the motor.
Disconnect power and release all pressure from
the system before attempting to install, service,
relocate or perform any maintenance.
OPERATION
PRIMING THE SHALLOW WELL PUMP
To prevent damage to the pump, do NOT start motor
until pump has been filled with water.
1. Remove prime plug (Figure 3).
2. Fill pump and piping completely full of water.
3. Replace the prime plug.
4. Open a faucet to vent the system.
5. Start the motor. Water will pump in a few minutes. If pump
fails to prime in 5 minutes, stop motor and refill pump with
water. Priming time is proportional to the amount of air in
inlet pipe.
6. Let the system operate for several minutes to flush all pipes.
7. Close faucet and allow pump to build pressure in tank. When
the pressure reaches the cut-out setting, the motor will stop.
The system is now in operation and will automatically cycle on
demand.
