INSTALLATION
8
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 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 gate valve 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. 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, 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 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 teflon
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 flow at 100 PSI
(690 kPa).
