INSTALLATION
APPLICATION
This pump is ideal for the supply of fresh water to rural
homes, farms, and cabins from drilled wells.
Submersible pumps are efficient, high in capacity,
require very little maintenance, and are generally very
economical for wells 60 feet (19 m) or more in depth.
GENERAL INFORMATION
NOTICE: The Model Number of your pump is located
on the top portion of the pump shell. Record this
number along with all pump installation data in the
section provided on page 2, keep it in a safe place for
future reference, in the event servicing is required. The
most important things you should know about your
well are: (1) its total depth; (2) depth to water; (3) draw
down water level. (4) well capacity-gpm.
1. The well total depth is the distance from the ground
level to the bottom of the well.
2. Depth to water is measured from the ground level
to the water level in the well when the pump is not
in operation.
3. Draw down water level is the distance from ground
level to the water while water is being pumped from
the well. In most wells, the water level drops when
water is being pumped.
4 Well capacity is the amount of water in gpm
that the well produces without drawing down or
water level dropping.
SUITABILITY OF WELL
IMPORTANT: The well should be fully developed
by the driller. It must be pumped until all fine sand
and foreign matter are removed before the pump is
installed. Make sure the well is large enough to allow
the pump to be set at the required depth. Do not set
the pump below the casing perforations or well screen
unless you are sure there is adequate flow of water
around the motor for cooling. To determine the correct
pump setting use the driller’s records by taking into
account the depth to water level and drawdown at
the proposed pumping rate. Always keep the pump a
minimum of five feet from the bottom of the drilled well.
GROUNDING
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.
Permanently ground all electrical components
in accordance with National Electrical Code and
applicable local codes and ordinances.
DO NOT ground to a gas supply line.
DO NOT connect to electric power supply until unit is
permanently grounded.
If a plastic well casing is used in your installation,
ground the metal well cap or well seal, providing
electrical leads to the pump motor go through the well
cap or well seal. Ensure correct wire size is used.
Refer to local electrical code.
CABLE SPLICING METHODS
When the drop cable must be spliced or connected
to the motor leads, it is necessary that the splice be
water tight. The splice can be made with commercially
available potting or heat shrink splicing kits. Follow the
kit instructions carefully.
A) HEAT SHRINK TUBING METHOD
RECOMMENDED METHOD (KIT ORDER # 453820)
1) Strip about ½" of insulation from cable and lead ends.
2) Slide about 3" long heat shrink tubing over the
cables.
3) Connect cable and lead ends with butt connector
(Figure 1).
4) Position the tubing over the connection keeping the
connector at its center.
5) Apply heat (about 135 °C) evenly on the tubing and
working from center outwards to avoid trapping air.
While heated, the adhesive liner inside the tubing
melts and the tubing shrinks quickly to encapsulate
and insulate the connection. The adhesive liner seals
the interfaces between the tubing and the connector
cable. Perfect sealing is achieved when adhesive
liner flows outside the tubing and seals the ends.
While heating, care must be taken not to overheat
the cable outside the tubing. This will damage the
insulation of the cable.
B) TAPE METHOD (alternative)
SPLICING SUBMERSIBLE CABLES WITH TAPE
Tape splicing should use the following procedure.
See Figure 2.
1) Strip individual conductor of insulation only as
far as necessary to provide room for a stake type
connector. Tubular connectors of the staked type
are preferred. If connector O.D. is not as large as
cable insulation, buildup with CSA/UL-approved
rubber electrical tape.
2) Tape individual joints with CSA/UL-approved rubber
electrical tape, using two layers, the first extending
two inches beyond each end of the conductor
insulation end, the second layer two inches beyond
the ends of the first layer. Wrap tightly, eliminating
air spaces as much as possible.
3) Tape over the rubber electrical tape with adhesive
tape or CSA/UL-approved PVC electrical tape,
or equivalent, using two layers as in Step 2 and
making each layer overlap the end of the preceding
layer by at least two inches.
In the case of a cable with three or four conductors
encased in a single outer sheath, tape individual
conductors as described, staggering joints.
