This is a safety switch which opens when a momentary

It is built into the pump motor (2-Wire motors

NOTICE: References
to "2-Wire" or "3-Wire" motors refer to
the load-carrying
wires running
to the motor. All motors
have a ground wire in addition to the load conductors,
so
that you will see four wires when looking at a "3-Wire"
motor (3 load conductors
plus a ground wire), and three
wires when looking at a _2-Wire" motor (2 load conductors
plus a ground wire). "3-Wire" motors require an electrical
disconnect
switch plus a Control Center; "2-Wire" motors
use only an electrical disconnect
switch.
The control center contains the electrical equipment
(other
than the pressure
switch) needed to start and run a 3-Wire
motor.

or kill To reduce
of electrical 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 assembly other than the pump, bond together all metal parts accessible 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 weid (or both if necessary) this bonding conductor
to the grounding means provided with the pump, which will
be the equipment_grounding
terminal, the grounding conductor 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 carties power cable conductors. Ground these back to the service
by connecting a copper conthtctor from the pump, motor, and
conduit to the grounding screw provided within the supplyconnection box wiring compartment. This conductor must be
at least as large as the circuit conductors supplying the pump.

GROUNDING
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 insulation 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 tile insulator,
tightening
them securely
by hand. This makes a
strong, waterproof
splice.
Method
(Figure 6)
Splice the wires with a butt-type connector using a crimphag tool. 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 onto
the insulator, tightening them securely by hand. This makes
a strong waterproof splice.

4. Trim centering
guides if necessary. Centering
guides will
fit 6 inch or larger well casings and 1 inch drop pipe. For
4 or 5 inch casings, the outside tabs must be trimmed with
a hacksaw or knife. See marks on tabs. For drop pipe sizes
1-1/4 and 1-1/2 inch, inside hole of guide must be
trimmed.
See marks on guide. NOTE: Do not cut hole
oversize. A snug fit works best.
5. Slide centering
guides on the plastic
pipe. First guide
should be located about 6 inches above the pump discharge connection.
Additional guides should be located
at equal intervals on the plastic pipe.
After placing first guide about 6 inches above the discharge connection,
place a stainless
steel hose clamp
above the guide. This will prevent guide from sliding up
pipe as pump is lowered in well. On other guides, place
clamp above and below it to maintain position.

6. Slide plastic pipe on to the nylon adapter until it is up to
the shoulder on the adapter. Clamp pipe to adapter with
2 stainless steel hose clamps. Place the screw mechanisms
on clamps opposite each other. Tape down excess length
of hose clamp band.
14.Tie safety rope to pump discharge
casting in holes provided. Thread the rope through the centering
guides. It
is not necessary
to tape rope to the pipe.
Remove as
ranch slack as practical and tie to ring in well seal or well
cap in the case of a pidess adapter.
7. Feed motor leads through the first centering
guide. Make
electric cable splices according
to choices on Pages 7 and
8. Stagger the splices by cutting one lead about 4 inches
longer than the other one. Tape splices to the plastic pipe.
Note that staggering prevents the splices from rubbing on
the well casing.

8. Unroll the balance of the electrical
cable along side of
plastic pipe. Be sure not to damage the insulation or kink
the wire. Now go back and feed the cable through
the
centering
guides located along the pipe.
15. To lower the pump into the well will require one person
at the well doing the actual lowering, and another at the
top end of the assembly. Stand as close as possible to well
and lower the unit. (Figure 10).

13.At about every five feet, tape electrical cable to the pipe
(Figure 9). Use 1-1/2 to 2 wraps of tape. This will allow
some freedom of cable movement
