Truma DuoComfort Instrucciones De Uso Instrucciones De Montaje página 12

In extreme cold or when a
large amount of gas is
consumed from the cylinder over
a long period of time, the gas
pressure may fall below 0.5 bar
even though there is still some
gas left in the cylinder. This may
result in gas being taken from
both gas cylinders simultaneously.
If needed, you can change the
position of the control knob at
any time.
Always turn control knob (a) as far
to the left or right as it will go (an
intermediate position will cause
gas to be removed from both gas
cylinders simultaneously).
Removal status
In the normal position (operating
cylinder on the left, reserve cyl-
inder on the right), the following
display will be seen:
12
– status display (b) is green =
gas taken from the left cylin-
der (operating cylinder).
– status display (b) is red =
gas is taken from the right cyl-
inder (reserve cylinder); check
connection and fill level of left
cylinder.
Changing cylinders
Residual gas: No smok-
ing! No open flames!
DuoComfort enables replace-
ment of an empty cylinder with-
out interrupting the operation
of devices currently consuming
the gas. Non-return valves inte-
grated into the inlet connecting
piece prevent gas from escaping
when only one gas cylinder is
attached for a short time (see
"Operating with only one gas
cylinder").
– Turn the control knob (a) by
180 degrees or half of a full
turn until it stops and the
former reserve cylinder
becomes the operating
cylinder. After the cylinder
change the full gas cylinder is
available again as the reserve
cylinder.
The status display (b) changes
to green.
– Close the empty cylinder's
valve and screw off the high
pressure hose.
– Screw the high pressure hose
onto the full gas cylinder and
open the cylinder's valve;
press the hose-break safety
device if present.
The status display (b) remains
green.
Anytime after making
changes, check the hose
