connection to the cylinder valve
for leaks (see "Checking for
leaks in the high pressure area").
Exchanging hoses
Residual gas: No smok-
ing! No open flames!
We recommend using the Truma
screwing tool (part no. 50020-
61500) whenever installing or
removing hoses. It will help you
generate the necessary tighten-
ing torque and will prevent dam-
age to the screw fittings, which
may otherwise result from using
an improper tool.
– Close the gas cylinder's valve.
– Remove the high pressure
hose from the gas cylinder (or
from the clip-on adapter) and
from the inlet to DuoComfort.
– Screw country-specific high-
pressure hose to DuoComfort
inlet and cylinder (or to
adapter).
– Open the gas cylinder's valve.
– Press the hose-break safety de-
vice and the gas-flow monitor
if present (see " SecuMotion,
MonoControl CS – Operating
instructions").
When performing a hose
change, please ensure
that the gasket provided with the
hose (hose outlet – changeover
valve inlet) is correctly installed
and not damaged.
We recommend that the
gasket (part no. 50020-
76300) be replaced with every
hose change.
Anytime after making changes,
check the hose connections to
the cylinder valve and to the
DuoComfort inlet for leaks (see
"Checking for leaks in the high
pressure area").
Operating with only one
gas cylinder
You can also use DuoComfort
with only one gas cylinder. Non
return valves integrated into the
inlet connecting piece prevent
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.
