Step 3A: Plug in the pump. The pump should start, pres-
surize the system, and stop when the pressure
gauge reads 2.6 to 3.6 Bars (37 to 52 psi).
Step 3B: When the pump stops, open a faucet to bleed
pressure off the system. Watch the pressure
gauge and note the pressure when the pump
starts.
Step 3C: Unplug the pump and adjust the Minimum
Operating Nut.
Step 3D: Repeat steps 3A, 3B, and 3C until the pump
starts at 1.6 to 1.7 Bars (23 to 25 psi) on the
pressure gauge.

With the pump plugged in, open a faucet to
bleed off pressure in the system. When the
pump starts, close the faucet and wait for the
pump to stop. As the pump runs through one
complete pressure cycle, check its operation
and its starting and stopping pressures.
Replace the pressure switch cover and the
pump is ready for operation.
