13.3. TANK VALVE – FUNCTION TEST
The easiest way of testing the tank valve is by the
"mouth method". For reasons of hygiene, attach a
suitable hose to the white part of the valve.
Test the tank valve by first sucking in the direction
towards the tank – the air should slowly pass. Blow
away from the tank and the valve should stop the
flow of air at low pressure.
The tank valve can also be tested with pressure
tester 531 03 06-23 or 501 56 27-01. The valve
must open at a maximum of 10 kPa under-
pressure. The opening pressure in the event of
over-pressure must be between 30 kPa.
13.4. FILTER - FUNCTION TEST
Detach the rubber hose with the sintered filter.
Blow by mouth through the hose and observe
whether air can slowly pass.
13.5. FILTER REPLACEMENT
Clogged filters should not be blown clean but
replaced. Use a pin punch to press the filter out
from the hose.
Press in a new filter on a flat surface.
