Blue: Valve setting low pressure side

Opening the valves opens the passages from the high-
pressure or low-pressure side to the service connec-
tion.

The pressure is measured with the valves open and
closed.
Open the valve: Turn the knob anticlockwise
•
Close the valve: Turn the rotary knob clockwise.

Always operate the two valve settings by hand only,
never with pliers. Closing the knob too tightly can dam-
age the knob or the valve.

hose from contamination.
