– Open the gas cylinder valve (1).
– Check the hose connection on the cylinder valve and on the gas fil-
ter / DuoControl inlet for leaks after every intervention (see “Check-
ing for leaks in the high-pressure section”).
Using only one gas cylinder
You can also use the DuoControl with only one gas cylinder. Non-
return valves integrated into the inlet connection prevent gas from
escaping through the unused connection.
The free inlet must be sealed off using the provided blind cover (brass)
if only one cylinder is being used.
– Turn the control knob (11) towards the operating cylinder.
Checking for leaks in the high-pressure section
The unions of the high-pressure hoses at the gas cylinder valve and
on the gas filter / DuoControl must be checked for leaks using suita-
ble means such as a leak-finder spray in accordance with EN 14291.
The operator is responsible for this.
Checking for leaks in the low-pressure section
(maximum test pressure 150 mbar)
The test must be conducted by a technician
