Preparing To Start The Pump - Pentair BERKELEY 5FN-L Manuel D'utilisation

Electrical / Preparing to Start the Pump
Connection Procedure:
Step 1. Connect the ground wire first as shown in Figure
7. The ground wire must be a solid copper wire
at least as large as the power supply wires.
Step 2. There must be a solid metal connection between
the pressure switch and the motor for motor
grounding protection. If the pressure switch is
not connected to the motor, connect the green
ground screw in the switch to the green ground
screw under the motor end cover. Use a solid
copper wire at least as large as the power supply
wires.
Step 3. Connect the ground wire to a grounded lead in
a service panel, to a metal underground water
pipe, to a metal well casing at least ten feet (3M)
long, or to a ground electrode provided by the
power company or the hydro authority.
Step 4. Connect the power supply wires to the pressure
switch as shown in Figure 7.

PREPARING TO START THE PUMP

Never run pump dry. Running pump
without water may cause pump to overheat, damaging
seal and possibly causing burns to persons handling
pump. Fill pump with water before starting.
Never run pump against closed discharge.
To do so can boil water inside pump, causing hazardous
pressure in unit, risk of explosion and possibly scalding
persons handling pump.
Figure 9: Prime the Pump
Step 1. Remove the priming plug from the priming tee
and fill the pump. Fill all piping between the
pump and the well and make sure that all piping
in the well is full. If you have also installed a
priming tee in the suction piping, remove the
plug from the tee and fill the suction piping.
Step 2. Replace all fill plugs.
Step 3. Power on! Start the pump. If you don't have
water after 2 or 3 minutes, stop the pump and
remove the fill plugs. Refill the pump and piping.
You may have to repeat this several times in
order to get all the trapped air out of the piping.
A pump lifting water 25' may take as long as 15
minutes to prime.
Step 4. After the pump has built up pressure in the
system and shut off, check the pressure switch
operation by opening a faucet or two and
running enough water out to bleed off pressure
until the pump starts. The pump should start
when pressure drops to 30 PSI and stop when
pressure reaches 50 PSI. Run the pump through
one or two complete cycles to verify correct
operation. This will also help clean the system of
dirt and scale dislodged during installation.
Congratulations on a successful installation.
If you were unsuccessful, please refer to the
Troubleshooting section (Page 9).
