Removal Status; Changing The Lpg Cylinder; Hose Change - Truma DuoControl Gebrauchsanweisung

Removal status

In the normal position (operating cylinder on the left, reserve
cylinder on the right), the following display will be seen:
– Status display (b) is green = gas taken from the left cylinder
(operating cylinder).
– Status display (b) is red = gas is taken from the right cylin-
der (reserve cylinder); check connection to the left cylinder
and the fill level.

Changing the LPG cylinder

Please use the included screw aid to attach and remove the
high-pressure hoses. It will help you generate the necessary
tightening torque and will prevent damage to the screw fittings,
which may otherwise result from using an improper tool.
Residual gas: No smoking, no naked flames!
DuoControl enables you to replace an empty gas cylinder
without interrupting the operation of consumers. Non-return
valves integrated into the inlet connections prevent gas from
escaping when only one gas cylinder is attached for a short
time (see "Using only one gas cylinder").
– Rotate the control knob (a) by 180° or half a turn to the stop
position, and the previous reserve cylinder becomes the
operating cylinder. After the cylinder change the full gas cyl-
inder is available again as the reserve cylinder.
The status display (b) changes to green.
– Close the valve of the empty gas cylinder.

– Remove the high-pressure hose from the gas cylinder and
remove the clip-on adapter, if present.
– Attach the high-pressure hose to the full gas cylinder and fit
the clip-on adapter, if present.
– Inspect the gas filter for the presence of residues.
– Open the full gas cylinder's valve.
– If necessary, firmly press the hose rupture protection (c –
green button) for about 5 seconds.
– The status display (b) remains green.
After making the connection, briefly turn back the control
knob (a) to the full gas cylinder to bleed the system (with the
consumer operating).
After any intervention, check the hose connection to the
cylinder valve for leaks (see "Checking for leaks in the
high-pressure section").
