Removal Status; Changing The Lpg Cylinder; Hose Change - Truma DuoControl CS Mode D'emploi Et Instructions De Montage

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 and fill level of left
cylinder.

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 fit‑
tings, which may otherwise result from using an improper tool.
Residual gas: No smoking, no naked flames!
– The DuoControl CS offers you the possibility of replacing
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 ("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 slip‑on adapter, if present.
– Attach the high pressure hose to the full gas cylinder and fit
the slip‑on adapter, if present.
– Open the full gas cylinder's valve.
– Firmly press the hose rupture protection (d – green button)
and, if necessary, the green reset button (c) for about 5 sec‑
onds in each case.
The status display (b) remains on 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").

Hose change

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 fit‑
tings, which may otherwise result from using an improper tool.
Residual gas: No smoking, no naked flames!
– Close the gas cylinder valve.
– Unscrew the high‑pressure hose from gas cylinder (or the
slip‑on adapter) and from the DuoControl CS inlet.
