Using Only One Gas Cylinder; Checking For Leaks In The High-Pressure Section; Checking For Leaks In The Low-Pressure Section - Truma DuoControl Mode D'emploi

– Unscrew the high-pressure hose from the gas cylinder (or the
clip-on adapter) and from the gas filter / DuoControl inlet.
When changing the hose, ensure that the seal provided
with the hose (hose outlet – regulator inlet) is correctly
installed and not damaged.
We recommend that the seal (part no. 50020-76300) be
replaced every time the hose is changed.
– Screw the country-specific high-pressure hose to the gas
filter / DuoControl inlet and to the cylinder (or the clip-on
adapter).
– Open the gas cylinder valve.
– If necessary, firmly press the hose rupture protection (c –
green button) for about 5 seconds.
– Check the hose connection on the cylinder valve and on the
gas filter / DuoControl inlet for leaks after every intervention
(see "Checking 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 (a) towards the operating cylinder.
Checking for leaks in the high-pressure
section
The screw joints of the high-pressure hoses at the gas cylin-
der valve and at the DuoControl must be checked for leaks
using suitable means such as a leak-finder spray in accord-
ance with DIN 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!
– Turn off all consumers.
– Open stop valves and, if present, the gas remote switch.
– Remove the threaded cap from the test connection (e)
and connect the test pump with test hose to the test
connection.
– Remove the protection cap from the test valve (f) and turn
the valve 90° clockwise with an open-ended spanner (span-
ner width 6 mm).
