Surge Protection

For protection against damage caused by high voltage
surges, your motor has built-in surge protectors. 

NOTICE:

Surge protectors 

will not

protect against direct or

near direct lightning strikes!

GROUNDING

Permanently ground all electrical components in accor-
dance with the National Electrical Code and applicable local
codes and ordinances. Make a permanent ground using a
conductor of correct size from a grounded lead in the ser-
vice panel or a properly driven and grounded ground rod.

DO NOT

ground to a gas supply line. 

DO NOT

connect to

electric power supply until unit is permanently grounded.

If 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. 

The grounding conductor need not be larger than the cir-
cuit conductors supplying the motor providing circuit con-
ductors conform to the wiring data provided in this manual. 

CABLE SPLICING 

NOTICE: 

Match colors of wires in cable to colors of wires

coming from motor.

For #14, #12, or #10 Wire Cable Installation 

Included in the splice kit are three plastic splice insulators
and four butt connectors; use two insulators on “2-Wire” mo-
tors and 3 insulators on “3-Wire” motors. The extra con-
nector is for the ground lead. The insulating sleeves can be
used on wire cable sizes #14, #12 and #10. No tape is re-
quired for this type of joint. To use the insulators stagger the
pigtail ends of the motor leads and the cable. Cut each lead
about 4" longer than the last one. 

Method #1: Soldering 

(Figure 6)

.

Stagger the pigtail ends of the motor leads and the cable. Cut
each lead about 4" longer than the last one. Trim the insula-
tion back 1/2" on each lead. Unscrew the plastic caps from
the insulator. Place parts on each end of the wire to be
spliced, as shown. 

Unscrew the plastic caps from the insulator. Place parts on
each end of the wire to be spliced, as shown in Figure 6.
Then proceed to splice the wires. Strip both wire ends about
1-1/2''. Be sure the surface is scraped clean. Overlap the two
ends so there is about 1/2” space between the insulation
ends. Twist the wire about 1-1/2 turns. With pliers, wind the
remaining wire on each end closely around the other wire as
shown. Use a soldering iron and a resin core solder or pure
solder with a non-acid soldering paste to solder the joint. 

After splicing, center the body of the insulator over the
splice. Slide the neoprene sleeves down into the recesses in
the body as far as they will go. Screw the caps on to the in-
sulator, tightening them securely by hand. This makes a
strong, waterproof splice.  

Method #2: Crimptype Connectors 

(Figure 6)

Stagger the pigtail ends of the motor leads and the cable. Cut
each lead about 4" longer than the last one. Trim the insula-
tion back 1/2" on each lead. Unscrew the plastic caps from
the insulator. Place parts on each end of the wire to be
spliced, as shown. 

Splice the wires with a butt-type connector using a crimp-
ing tool. After splicing, center the body of the insulator over
the splice. Slide the neoprene sleeves down into the re-
cesses in the body as far as they will go. Screw the caps onto
the insulator, tightening them securely by hand. This makes
a strong waterproof splice.

Important Electrical Grounding Information

Hazardous voltage. Can shock, burn,
or kill. To reduce the risk of electri-

cal shock during pump operation, ground and bond the
pump and motor as follows:

A. To reduce risk of electrical shock from metal parts of the as-

sembly other than the pump, bond together all metal parts ac-
cessible at the well head (including metal discharge pipe, metal
well casing, and the like). Use a metal bonding conductor at
least as large as the power cable conductors running down the
well to the pump's motor. 

B. Clamp or weld (or both if necessary) this bonding conductor

to the grounding means provided with the pump, which will
be the equipment-grounding terminal, the grounding conduc-
tor on the pump housing, or an equipment-grounding lead.
The equipment-grounding lead, when provided, will be the
conductor having green insulation; it may also have one or
more yellow stripes.

C

. Ground the pump, motor, and any metallic conduit that car-

ries power cable conductors. Ground these back to the service
by connecting a copper conductor from the pump, motor, and
conduit to the grounding screw provided within the supply-
connection box wiring compartment. This conductor must be
at least as large as the circuit conductors supplying the pump.
