Removal Status; Changing The Lpg Cylinder; Hose Change - Truma DuoControl CS Operating Instructions Manual

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
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 cylinder
(reserve cylinder); check connection and fill level of left
cylinder.

Changing the LPG cylinder

Please use the included screwing tool 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: Do not smoke, avoid open flames!
– DuoControl CS enables replacement of an empty cylinder
without interrupting the operation of devices currently con-
suming the gas. Non-return valves integrated into the inlet
connecting pieces prevent gas from escaping when only
one gas cylinder is attached for a short time ("Operating
with only one gas cylinder").
– Rotate 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
cylinder is available again as the reserve cylinder.
The status display (b) changes to green.
– Close the empty gas cylinder's valve.
– 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.
– Open the full cylinder's valve.
– Press the hose rupture protection (d – see "Startup").
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 gas
consumer operating).
Whenever changes have been made, check the hose
connection to the cylinder valve for leaks (see "Checking
for leaks in the high-pressure area").

Hose Change

Please use the included screwing tool 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: Do not smoke, avoid open flames!
– Close gas cylinder valve.
– Unscrew high-pressure hose from gas cylinder (or clip-on
adapter) and from DuoControl CS inlet.
