NOTICE: Keep torch moving. Too much
concentrated heat may damage tubing
(see Figure 9).
C. Butt Connectors with plastic insulators (for
14, 12 and 10 Gauge AWG Wire, or 2, 3
and 5.5mm
wire):

1. Cut off motor leads. Stagger lead and
wire length so that 2nd lead is 4"
(100mm) longer than 1st lead and 3rd
lead is 4" (100mm) longer than second.
2. Cut off cable ends. Be sure to match
colors and lengths of wires in drop cable
to colors and lengths of motor leads.
3. Trim insulation back 1/2" (13mm) from
cable ends and motor lead ends.
4. Unscrew plastic caps from insulators.
Place a cap and a neoprene gasket
sleeve on each wire end to be spliced
(see Figure 10).
5. Slide insulator body onto one wire end
(Figure 10).
6. Insert wire end into butt connector and
crimp (see Figure 11). Be sure to match
cable and motor wire colors.
7. Center insulator body over splice and
slide neoprene sleeves into body as far
as they will go. Screw caps onto
insulator body (Figure 12) and tighten by
hand for a strong, waterproof splice.

CABLE INSTALLATION

1. To test submersible, momentarily connect it
to proper power supply. Power supply
frequency and voltage must match motor
nameplate frequency and voltage to within
±10%. (3 Phase pumps – see "Rotation,"
Page 3).
2. Fasten cable leads securely to pump
discharge section; leave 4-5" (100-127mm) of
slack in leads at this point. Securely fasten
leads to plastic pipe within 6" (150mm) of the
pump discharge section. Use torque arresters
to protect pump and pipe from twisting
damage as pump starts and stops.
3. Connect copper ground wire to motor
bracket. Ground wire must be at least as large
as wires supplying current to motor. Consult
current National Electrical Code, Canadian
Electrical Code and local codes (as
applicable) for grounding information.
4. Use only submersible cable supplied by pump
manufacturer. When lowering pump into well,
secure cable to discharge pipe at 10' (3.5M)
intervals with Scotch #33 electrical tape. Take
care not to damage pump cable.
NOTICE: To avoid dropping the pump down
the well or damaging cable or cable splices,
NEVER allow pump cable to support weight
of pump.

PUMP INSTALLATION

1. If a standard air over water pressure tank is
being used, install two bleeder orifices about
2' (.6M) apart as shown in Figure 15, Page
21. These orifices will automatically charge
the tank with air. See Figure 15 to determine
orifice location.
NOTICE: If Pre-charged tank is used, DO
NOT install bleeder orifices. If pump and pre-
charged tank are replacing a standard tank
system, remove bleeder orifices before
installing pump in well.
2. To prevent losing pump down the well,
connect a safety rope strong enough to
support pump and drop pipe (minimum 5/16"
(8mm) twisted polypropylene or pronila rope)
to eyelet on pump discharge. Tie off other
end of safety rope securely to well seal, well
cap or pitless adapter.
3. Discharge outlet is threaded 2" NPT (60 Hz)
or 2" BSP (50 Hz).
Use 100 PSI rated polyethylene plastic pipe
for installations up to 100' depth.
Use 160 PSI rated polyethylene plastic pipe
for installation up to 220' depth.
For depths beyond 220', use galvanized steel
pipe for the entire drop pipe.
INITIAL START-UP
NOTICE: NEVER operate pump with discharge
valve completely closed. Pump can destroy itself
if run with discharge shut off ("deadheaded") and
warranty will be void.
NOTICE: To avoid sand-locking pump, follow
procedure below when starting pump for the
first time. NEVER start a pump with discharge
completely open unless you have done this
procedure first.
1. Connect a pipe elbow, a short length of pipe
and a gate valve to pump discharge at well
head (see Figure 13).
2. Mount motor control box (3-wire pump),
fused disconnect switch (2-wire pump), or
magnetic starter (3-phase pump) in a
permanently weather proofed place. Make
sure that controls will not be subjected to
extreme heat or excess moisture.
3. Make sure controls are in OFF position.
4. Connect motor leads and power supply to
motor control box, fused disconnect switch, or
magnetic starter (see Wiring Diagrams, Pages 8
through 12). DO NOT START PUMP YET.
5. Set gate valve on discharge 1/3 open; start
pump (see Figure 13).
6. Keep gate valve at this setting while water
pumps out on ground. Let it run until water is
clear of sand or silt. (To check solids in water,
fill a glass from pump and let solids settle out).
