Operating Instructions and Parts Manual
Deep Well Submersible Pump
Installation
WIre SPlICInG
Splice wire to motor leads. Use only
copper wire for connections to pump/
motor assembly and control box.
Heat shrink splice instructions (wire sizes
No. 14, 12 and 10 AWG [2, 3 and 5mm
2 ]):
1. Remove 3/8" (9.5 mm) insulation
from ends of motor leads and power
supply wires.
2. Place heat shrink tubing over motor
leads. Position tubing between
power supply and motor.
3. Match colors of supply wires with
colors of motor leads.
4. Insert supply wire and lead ends
into butt connector and crimp (see
Figures 2 and 3). Match colors of
supply wires with colors of motor
leads. Check lead connections by
gently pulling on them.
5. Center tubing over butt connector
and apply heat evenly with torch
(match or lighter will not supply
enough heat).
Keep torch moving.
Too much
concentrated heat MAY damage tubing
(see Figure 4).
Instructions for mechanical splice kit
with plastic insulators (wire sizes 14, 12,
and 10 AWG [2, 3, and 5 mm
2 ]):
1. With wire cutting tool, cut off motor
leads. Stagger lead and wire length
so that second lead is 4" (101.6 mm)
longer than first lead and third lead
is 4" (101.6 mm) longer than second.
2. With wire cutting tool, cut off wire
ends. Match colors and lengths of
wires between power supply and
motor.
3. With wire stripping tool, trim
insulation back 1/2" (12.7 mm) from
power supply wire and motor lead
ends.
4. Unscrew plastic caps from insulators.
Place a cap and neoprene gasket
sleeve on each wire to be spliced
(see Figure 5).
5. Slide insulator body onto one wire
end (Figure 5).
6. Insert wire end into butt connector
and crimp. Match wire colors
between power supply and
motor (see Figure 6). Check lead
connections by gently pulling on
them.
7. Center insulator body over splice
and slide gasket sleeves into body as
far as they will go. Screw caps onto
insulator body (Figure 7) and tighten
by hand for a strong, waterproof
splice.
POWer SUPPly WIre InSTallaTIOn
1. to test pump, connect it to proper
power supply for a short amount
of time (no more than 30 seconds).
Power supply frequency and
voltage must be within 10% of
frequency and voltage shown on
product nameplate.
2. Fasten power supply wire leads to
pump discharge block. then fasten
leads to plastic pipe within 6"
(150 mm) of discharge block. Use
centering guides to prevent wire
and pipe from rubbing well casing.
3. Connect copper grounding wire
to motor bracket. Grounding wire
must have a diameter at least that
of wires supplying current to motor.
Consult national electrical Code, as
well as local code, for grounding
information and safety guidelines.
4. Use only submersible power
supply wires supplied by pump
manufacturer. When lowering
pump into well, secure supply wires
to discharge pipe at 10 ft. (3,1 m)
intervals with #33 electrical tape.
Take care not to damage pump
wires.
To avoid dropping
pump down well or
damaging wires or splices, NeveR allow
pump wires to support weight of pump.
PUMP InSTallaTIOn
1. If standard air-over-water pressure
tank is used, install two bleeder
orifices about 2 ft. (0.6 m) apart
as shown in Figure 10, on page 6.
orifices will automatically charge the
tank with air. See Figure 10 to help
determine orifice location.
nOTe: If precharged 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 safety rope strong
enough to support pump and drop
pipe (minimum 5/16" [8 mm] 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.
nOTe: Discharge outlet is 1-1/2" nPt
threaded.
3. Install piping based on these
guidelines:
For installations up to 100’ (30.5 m)
in depth, use 100 psi (689.5 kPa)
rated polyethylene plastic pipe.
For installations up to 220’ (67.1 m)
in depth, use 160 psi (1103.2 kPa)
rated polyethylene plastic.
For depths beyond 220’ (67.1 m),
use galvanized steel pipe for the
entire drop pipe.
InITIal STarTUP/neW WellS
NeveR operate
pump with
discharge valve completely closed. This
CAN cause significant pump damage
and WIll void the warranty.
