PRE-INSTALLATION PREPARATION:
CAUTION: DO NOT run pump dry. Pump can be severely damaged if run dry.
The pump has been factory tested with the same motor assembled to it.
For safe testing, wait until pump is wired, grounded and completely submerged.
THE WELL:
Pump performance is based on pumping clear, cold water with no entrained air. The well driller should properly develop the well, i.e.

replacement of the pump. The water tank and electrical controls can, of course, be located some distance from the well. Determine the
depth of the pump in the well, using the well drillers record, taking into

drop at the motor. Consult dealer or electrician.
DROP PIPE:

Galvanized pipe is recommended for suspending all submersible pumps into the well, although it is used mainly for high capacity, high
head pumps. Requires a power lift and pipe holder for installation and removal. Since galvanized pipe is rigid, problems due to starting
torque are not present.
Rigid PVC plastic pipe is installed in lengths as is galvanized pipe. Easier to handle due to light weight. Safety rope is
recommended if cement type couplings are used. Often used on high capacity, medium to low head pumps.
Flexible polyethylene pipe is most commonly used on domestic size pumps. Plastic pipe manufacturers recommendations of depth
and pressure must be observed. Pressure rating must be greater than maximum pressure of pump. Pipe should be double
clamped with all stainless steel clamps. Safety rope to prevent loss of pump recommended. A torque arrestor is recommended just

CHECK VALVES:
The pump may have a built-in or externally supplied check valve. For a pump without one, install a spring-loaded check valve
immediately above the pump. Install an additional spring-loaded check valve above ground. If the pump is more than 100 feet below the
well head, install another spring–loaded check valve in the drop pipe 100 feet above the pump. For pump setting deeper than 200 feet,
install additional spring-loaded check valves at intervals of 100 feet. DO NOT use swing type check valves because they have a slower
reaction time and can cause water hammer.
LOCATION OF WATER TANK & ELECTRICAL CONTROLS:
Always install the pressure tank and electrical controls in a clean, dry basement or utility room to avoid dampness and temperature
extremes. In any installation where the pump pressure could exceed the water storage tank pressure, provide a pressure relief valve
piped to a suitable drain.
LIGHTNING ARRESTORS:

indicated on the motor frame label. Franklin 4” three phase “super stainless” motors thru 3 HP, 200 and 230 volt only, have built-in
lightning arrestors, indicated on the motor frame label. All other three phase motors require a separate lightning arrestor installed as
close to the wellhead as possible. Install the arrestor in accordance with
manufacturers recommendations. A lightning arrestor provides protection against induced voltage surges on secondary power lines;
it is not effective against direct hits. The arrestor must be grounded, metal to metal, all the way to the water strata, for it to
be effective. Grounding the arrestor to a driven ground rod provides little or no protection for the motor. Many present-day
electrical codes require a ground wire from the pump to the supply grounding terminal. When this ground wire is used, the above-
ground arrestor can be grounded acceptably by connecting to it.
INSTALLATION
SPLICING THE POWER CABLE:
Follow the instruction enclosed in the cable splicing kit you purchase.
ROTATION (3 Phase Only):
To make sure motor is running in the right direction, test run the pump before installation carefully as follows: After
electricalconnectionshavebeenmade(seeFig.5),bracepumpcasingsecurelyandapplypowermomentarily by
snapping line switch quickly on and off. If rotation is correct, reaction of the pump casing will be clockwise when viewed from the pump
discharge, i.e. the pump will jerk clockwise when looking into the pump discharge when started. If the pump jerk is counter-clockwise,
this means the motor is running in the wrong direction. Interchange any two cable leads where they connect to the “T” terminals in the
magnetic starter to reverse rotation. A three phase submersible motor
requires a magnetic starter equipped with quick-trip, ambient-compensated overloads (heaters) of correct size for the horsepower of
the motor. Consult dealer or electrician.
CAUTION: DO NOT run pump dry other than momentarily as described above.
Pump can be severely damaged if run dry.
