Installation (Continued)

3. Install a valve and isolator hose between

the system and the house plumbing to

aid in pump removal for servicing and

for reducing noise transmitted to the

house through the piping.

4. Provide a hose bib (faucet) at the

lowest point in the system to drain

for service or storage.

CONVERTING THE DEEP WELL PUMP TO

SHALLOW WELL OPERATION (FIGURE 8)

For shallow wells (25 feet or less), a

bolt-on shallow well jet is available

as an accessory for deep well pumps.

The jet attaches to the front of the

pump with the two bolts provided and

converts the deep well pump into a

shallow well pump. The shallow well

jet has a 1 in. NPT inlet and a 1/8 in.

NPT opening for an air volume control.

For optimum performance, an inline

check valve on the inlet side of the

shallow well jet is recommended.

Electrical

Risk of electrical

shock. This pump is

designed for indoor installation only.

Select the proper size wire and

fuse (Chart 2). 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 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 9).

The ground conductor must not be

smaller than the circuit conductors

supplying the motor.

The voltage of power supply must match

the voltage of the pump. The unit has

dual voltage motors preset at the factory

to 115 volts. The motors can be converted

to 230 volts by turning the voltage

selector to the desired voltage (see Figure

10, on page 5). Disconnect power, use

needle nose pliers to pull the selector out

approximately 1/4 in., rotate, and then

reinsert in correct position.

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.

NOTE: When the deep well pump is used

with the bolt-on shallow well jet, be sure

the control valve slot (Figure 11, on page

6) is in the vertical (open) position at all

times.

1. Remove prime plug.

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. Do

not allow pump to get hot.

6. Let the system operate for several

minutes to flush all pipes.
