Truma DuoControl Mode D'emploi page 14

– Screw country-specific high-pressure hose to DuoControl
inlet and cylinder (or to adapter).
– Open gas cylinder valve.
– When using high-pressure hoses with hose rupture protec-
tion, press green button.
– Check hose connection to cylinder valve and DuoControl
inlet for leaks after every modification (see "Leak-testing in
the high pressure area").
Operating with only one gas cylinder
You can also use DuoControl with only one gas cylinder. Non
return valves integrated into the inlet connecting piece pre-
vent gas from escaping through the unused connecting piece.
The free inlet must be sealed off using the provided dummy
cover (brass) if only one cylinder is being used.
Turn rotary knob in direction of operating cylinder.
Leak-testing in the high pressure area
Leak-test the screw fittings for high-pressure hoses on the gas
cylinder valve and on the DuoControl changeover regulator
with appropriate equipment, such as a leak-detection spray
according to DIN EN 14291.
This is the responsibility of the operator.

Checking for leaks in the low
pressure area
(maximum test pressure 150 mbar)
Test must be conducted by a technician!
– Turn off all consumers.
– Open stop valves and, if present, 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 protective cap (f) from the test valve, and turn
the valve 90° clockwise with an open-ended spanner (span-
ner width 6 mm).
– Conduct leak test (in Germany according to G 607, for
example).
– If gas system exhibits a leak, close the gas cylinder valve
and have the gas system repaired immediately by an expert;
do not open the gas cylinder valve until repair is complete.
– After the check is complete, be sure to turn the test valve
back (90° counter-clockwise until it will turn no further) and
replace the protective cap.
– Screw the threaded cap back onto the test connection.
