The take-off hose ventilation can be unscrewed for
cleaning when necessary, in case these rubber parts in
the interior of this valve become dirty or stuck because of
residues.
The pressure monitor is
simply unscrewed.
The air should be able to
enter the hose from the hol-
der - not the other way
around!
