Operation
PRIMING / OPERATION
Never run pump dry. Running pump with-
out water may cause it to overheat, damaging the seal
and possibly causing burns to persons handling the
pump. Fill the pump with water before starting.
Never run the pump with the discharge
closed. To do so can boil water inside the pump, causing
hazardous pressure in the unit, risk of explosion, and
possibly scalding persons handling the pump.

Cistern Installation
1. Remove the priming plug from the priming port. Fill
the pump from the tee and let it vent through the
port. Fill all piping between the pump and the water
source and make sure that all vertical suction piping
is full.
2. Replace all priming plugs (use teflon tape).
3. Power on! Start the pump. If you don't have water in
2 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 remove all the trapped
air from the piping. A pump lifting water 15' (4.5m)
may take as long as 15 minutes to prime.

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 1.6 Bars
(22 psi) and stop when pressure reaches 2.2 to 4.2
Bars (32 to 62 psi), depending on the setting (Step 4,
Page 5). 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.
