9/16-inch open-ended wrench
Do this task when the pump is not running.
Make sure that the value on the prefilter water-pressure gauge is between 2.8 bar and 7.6 bar (280 kPa
and 760 kPa / 40 psi and 110 psi).
If the pressure is not in this range:
1. Loosen the jam nut on the regulator.
2. Turn the T-handled adjustment screw clockwise to increase the pressure or counterclockwise to
decrease pressure.
3. Tighten the jam nut.

Measure the air pressure in the water accumulator tank

Refer to Measure the air pressure in the water accumulator tank on page 92 for instructions.

Do not set the boost pump pressure higher than 7.6 bar (760 kPa / 110 psi).
The supply water components are rated for a maximum of 8.6 bar (860 kPa / 125 psi).
High pressure can cause damage to the components.
