Adjust the boost pump pressure
Do this task when the pump is operating in cooling mode.
1. Make sure that the value on the prefilter water-pressure gauge is between 6.9 bar and 7.6 bar
(100 psi and 110 psi).Remove the rear cover of the pump.
2. Pull out the boost pump pressure regulator knob on the water manifold. Turn it clockwise to
increase the pressure or counterclockwise to decrease pressure.
Measure the air pressure in the water accumulator tank
Refer to Low-pressure water on page 91 for instructions.
CAUTION
Do not set the boost pump pressure higher than 7.6 bar (110 psi).
The supply water components are rated for a maximum of 8.6 bar (125 psi). High pressure
can cause damage to the components.
If the supply water is from a reverse osmosis system, contact a Hypertherm Technical
Service Associate for information and support.
