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. (3M) intervals with Scotch #33
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.
PUMP INSTALLATION
1. If standard air over water pressure tank is used, install two
bleeder orifices about 2 ft. (.6M) apart as shown in Fig. 12.
Orifices will automatically charge the tank with air. See Fig. 12 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 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 1-1/4" NPT 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 installa-
tions 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 discharge valve completely
closed. Pump can destroy itself if run with discharge shut off ("dead-
headed") 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 dis-
charge 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 Fig. 10).
2. Mount motor control box (3-wire pump) or fused disconnect
switch (2-wire pump) in a permanently 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 motor control box 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. 10).
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, fill a glass from pump and let solids settle out).
7. When water is completely clear at 1/3 setting, open gate valve to
approximately two-thirds 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 (see
Figs. 11 and 12).
10. Install sanitary well seal or pitless adapter unit, well unit, electri-
cal conduit and surface piping. Installation must meet all code
requirements that apply.
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
flow at 75 PSI (517.1kPa) when using an air over water pressure
tank. Install a pressure relief valve capable of passing entire
pump flow at 100 PSI (690 kPa) when using a pre-charged pres-
sure tank. Install this relief valve between pump and tank.
Pipe joint compound can cause cracking in plastics.
Use only teflon tape on joints in plastic pipe.
NOTICE: Allowing pump or piping system to freeze may severely dam-
age pump and will void warranty. Protect pump and entire piping system
(including pressure tank) from freezing.
PRE-CHARGED PRESSURE TANK HOOKUP
See Fig. 11 for piping connections to pre-charged pressure tank.
NOTICE: Check air pre-charge in tank before starting pump. Adjust
pre-charge to 2 PSI (13.8 kPa) 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 tire valve located on top of tank. Check pre-charge annually
and adjust as needed.
STANDARD TANK HOOKUP
See Fig. 12 for piping connections to standard pressure tank and for
correct distance of bleeder orifices from pressure tank.

Important Electrical Grounding Information
Hazardous voltage. Can shock, burn,
or kill. To reduce the risk 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 weld (or both if necessary) this bonding conductor to the
grounding means provided with the pump, which will be the equip-
ment-grounding terminal, the grounding conductor on the pump
housing, or an equipment-grounding lead. The equipment-ground-
ing lead, when provided, will be the conductor having green insula-
tion; it may also have one or more yellow stripes.
C. Ground the pump, motor, and any metallic conduit that carries
power cable conductors. Ground these back to the service by con-
necting 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
