Changing The Lpg Cylinder; Hose Change - Truma DuoControl Gebrauchsanweisung, Einbauanweisung

– 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 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 fittings,
which may otherwise result from using an improper tool.
Residual gas: Do not smoke, avoid open flames!
DuoControl enables replacement of an empty cylinder without
interrupting the operation of devices currently consuming the
gas. Non-return valves integrated into the inlet connecting
piece prevent gas from escaping when only one gas cylinder
is attached for a short time ("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 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 (c) if present (see "Taking
into operation").
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).
Anytime after making changes, check the hose connec-
tion to the cylinder valve for leaks (see "Leak-testing 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 adapter)
and from DuoControl inlet.
When performing a hose change, please ensure that
the gasket provided with the hose (hose outlet – regula-
tor inlet) is correctly installed and not damaged.
We recommend that the gasket (part no. 50020-76300)
be replaced with every hose change.
