INSTALLATIONS
10
Discharge outlet is 1-1/4” FNPT threaded. Use 100 PSI
(689.5kPa) rated polyethylene plastic pipe for installations
up to 100’ (30.5M) depth.
Use 160 PSI (1103.2 kPa) rated polyethylene plastic for
installations up to 220’ (67.1M) depth.
For depths beyond 220’ (67.1M) use galvanized steel
pipe for the entire drop pipe.
INITIAL START-UP/NEW WELLS
NOTICE: NEVER operate pump with gate valve completely
closed. Pump can destroy itself if run with valve shut o
(“dead- headed”) and warranty will be void.
NOTICE:
To avoid sand-locking pump, follow procedure below
when starting pump for the rst time. NEVER start a pump
with gate valve completely open unless you have done this
procedure rst.
1. Connect a pipe elbow, a short length of pipe and a
gate valve to pump discharge at well head (see Fig. 3).
2. Mount submersible motor control (3-wire pump) or
fused disconnect switch (2-wire pump) in a perma
nently weatherproof 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
submersible motor control or magnetic starter
(see Installation Wiring Diagrams).
DO NOT START PUMP YET.
5. Set gate valve on discharge 1/3 open; start pump
(see Fig. 3).
6. Keep gate valve at this setting while water pumps
out on ground. Let run until water is clear of sand or
silt. (To check solids in water, ll a glass from pump
and let solids settle out).
7. When water is completely clear at 1/3 setting, open
gate valve to approximately 2/3 open and
repeat process.
8. When water is completely clear at 2/3 setting, open
gate valve completely and run pump until water is
completely clear.
9. Remove gate valve for permanent installation near
tank (Fig. 4).
10. Install sanitary well seal or pitless adapter unit, well
unit, electrical conduit and surface piping. Installa-
tion must meet all code requirements that apply.
.
Pipe joint compound can cause
cracking in plastics. Use only Teon
tape on joints in plastic pipe.
NOTICE:
Allowing pump or piping system to freeze may severely
damage pump and will void warranty. Protect pump and
entire piping system (including pressure tank) from freezing.
Pre-Charged Pressure Tank Hookup
See Fig. 4 for piping connections to pre-charged pressure tank.
NOTICE:
Check air pre-charge in tank before starting pump. Adjust
pre-charge to 2 PSI (13.8kPa) below pump cut-in setting,
(ie, a pre-charge tank used with a 30-50 switch should be
pre-charged with air to 28 PSI (193.1 kPa). Adjust pre-charge
by adding or bleeding air through schrader valve located
on top of tank. Check pre-charge annually and adjust as
needed.

Connecting To Tank/Water System
Hazardous pressure. Submersible
pumps can develop very high pressure
in some situations. To prevent tank blowup, install a pressure relief
valve able to pass full pump ow at 100 PSI (690 kPa).
TEMPORARY CONNECTIONS WHILE CLEANING
WELL FOR START-UP
Power Supply Wire Installation
1. To test submersible, momentarily (no more than 5
seconds) connect it to proper power supply. Power
supply frequency and voltage must match motor name
plate frequency and voltage to within ±10%.
2. Fasten power supply wire leads securely to pump
discharge section; leave 4-5” (100-125mm) of slack in
leads at this point. Securely fasten leads to plastic pipe
within 6” (150mm) of the pump discharge section. Use
centering guides to protect wire and pipe from rubbing
well casing.
3. Connect copper ground wire to motor bracket. Ground
wire must be as large as wires supplying current to
motor. Consult current Canadian Electrical Code and
local codes for grounding information.
4. Most 4” pumps have an eyelet on the pumps discharge
for attaching a rope to assist in lowering into and
pulling the pump from the well. Attach a nylon rope of
adequate length to eyelet
5. Do not use submersible power supply wires supplied
by pump manufacturer to lower or lift pump. When
lowering pump into well use only the rope and/or
discharge pipe, secure supply wires to discharge pipe
at 10 ft. (3M) intervals with Scotch™ #33 or equivalent
electrical tape. DO NOT damage pump wires.
NOTICE:
To avoid dropping pump down well or damaging wires
or splices, NEVER allow pump wires to support weight
of pump.
