Checking the filter regulator
The following tasks need to be carried out when setting and cleaning the filter
regulator.
Setting the filter regulator
To set the pressure desired at the filter regulator, pull the
setting knob up and turn it until the pressure is below the
new pressure to be set.
Now turn the setting knob in the opposite direction and
approach the desired pressure setting from the low
pressure.
Draining the filter regulator
Depending on the condensation level in the reservoir, drain
it by pressing the plastic knob against the reservoir => This
causes the valve to open.
The condensation level may never be allowed to rise above
the maximum marking (applied to reservoir).
Cleaning the filter elements of the filter regulator
When a substantial pressure drop is noticeable, clean the filter element and
the reservoir.
Clean the filter element using benzene, petroleum or similar agent, followed
by air-flushing it from the inside to the outside. When reinserting the element
make sure it is dry.
The reservoir and the other plastic components may only be washed using
warm water and dish washing liquid.
