Franklin Submersible Well Pump Installation Of Pump, Drop Pipe, And Associated Equipment

INSTALLATION OF PUMP, DROP PIPE, AND ASSOCIATED EQUIPMENT

Fig. 1 illustrates a typical well installation showing in ground components. Adhere to the following items when installing the pump and drop pipe:

1.Fasten the submersible cable to the drop pipe with clamps or appropriate tape every 10 ft. (3m) to prevent tangling and damage to the cable. The cable must remain slack when using plastic drop pipe to allow for stretching of pipe when installed in the well.

2.Take care not to scrape or pinch the submersible cable against the well casing.

3.Use an ohmmeter or megger to make insulation and continuity checks on the cable once the pump is installed. This locates any fault in the cable.

4.Make sure a check valve is installed immediately above the pump. Install additional check valves at 100’ (30m) intervals.

5.Install a torque arrestor just above the pump to prevent chafing the cable when pump anad pipe twist during starting and stopping.

6.Attach a safety cable to pump to prevent loss of pump if pipe should break.

7.Place a sanitary well seal or pitless adapter with an approved cover plate over top of well per manufacturers recommendations.

8.Keep pump at least 5’ (1.5m) from bottom of well and above well screen or casing perforations.

ELECTRICAL INFORMATION

1.	Employ a licensed electrician to perform the wiring.
	All wiring must be done in accordance with applicable
	national and local electrical codes.
2.	Check that the power supply corresponds with the
	electrical rating of the submersible motor and the
	control box(if required). Make sure that the control box
	electrical rating matches the motor electrical rating.
3.	Every installation requires a fused disconnect switch
	or circuit breaker.

secondary power lines; it is not effective against direct hits.

6.Mount the control box in an area protected from rain, snow, direct sunlight or other high temperatures as this may cause tripping of the overload protector.

Also protect the control box from extreme cold (below 25oF/-32oC) as this may have adverse effects on starting capacitor.

7.A two-wire pump does not require a motor control box, since all electrical components are built inside the motor. Fig. 2 shows a typical wiring diagram for a two- wire installation.

8.A three-wire, single-phase pump requires a motor control box incorporating overload relays. Fig. 3 shows a typical wiring diagram for a three-wire, single- phase installation. Note that a magnetic contactor must be used if the pressure switch electrical rating is not sufficient to handle the submersible motor electrical rating. The pressure switch would then be incorporated into a pilot circuit to control the magnetic contactor. Make the connections at the control box in accordance with the wiring diagram in the control box to avoid damage to the motor.

4. Every installation must be grounded. There must be

a reliable ground connection between the pump and

the distribution panel. The motor lead incorporates a

green grounding conductor.

5. Lightning arrestors are recommended for every

installation. All stainless steel, single phase motors

thru 5HP have built-in lightning arrestors. Any 6”

motor or 4”, 3-phase motor requires a separate

lightning arrestor installed as close to the wellhead

as possible. Install the arrestor in accordance with
