Connecting To Tank/Water System - Pentair PRO-SOURCE 8MM05231 Notice D'utilisation

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 Figures 14 and 15, Pages 10
and 11).
10. Install sanitary well seal or pitless adapter
unit, well unit, electrical conduit and surface
piping according to local code requirements.

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 kPa) 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
pressure tank. Install this relief valve between
pump and tank.
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.

Standard Tank Hookup:
See Figure 15, Page 11 for piping connections to
standard pressure tank and for correct distance
of bleeder orifices from pressure tank.
Pre-charged Pressure Tank Hookup:
See Figure 14, Page 10 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. (For example, a
pre-charge tank used with a 30-50 switch
should be pre-charged with air to 28 PSI (193
kPa) . Adjust pre-charge by either adding or
bleeding air through tire valve located on top of
tank. Check pre-charge annually and adjust as
needed.
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
equipment-grounding terminal, the grounding
conductor on the pump housing, or an
equipment-grounding lead. The equipment-
grounding lead, when provided, will be the
conductor having green insulation; it may also

C. Ground the pump, motor, and any metallic
conduit that carries power cable conductors.
Ground these back to the service by
connecting 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
