Preparing To Start The Pump - Berkeley 5HN Serie Mode D'emploi

Preparing to Start the Pump

PRIMING
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.
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.

Step 1. Remove the priming plug from the pump 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 sys-
tem and shut off, check the pressure switch oper-
ation by opening a faucet or two and running
enough water out to bleed off pressure until the
pump starts. The pump should start when pres-
sure 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.
