Operation

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 2 Bars
(30 psi) and stop when pressure reaches 3.4 Bars (32
to 50 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.

Operation As A Rooftop
Reservoir Booster Pump
1. Open both suction and discharge faucets.
2. Turn on power to pump. The pump should start.
3. Let the pump run until all air is out of the system and
the faucet is running only water.
4. When the faucet is running only water, close the
faucet. The pump should run until the water pressure
rises to the pressure switch's OFF setting. The pump
should then stop.
NOTE: Check the system by running it through one
complete pumping cycle to make sure it works. To do
this, open a faucet and bleed off pressure until the
pump starts. Close the faucet, and when the pressure
in the system has built up again, the pump should
stop.
