via the drain valve. Place a bucket beneath 
the outlet to check whether the water content 
has completely drained away (10 litres). There 
shall be no claims under guarantee for damage 
caused by frost!

maintenance

Only original Truma parts may be used for 
maintenance and repair work!
The water container used is made of stainless 
steel, which is foodstuff-compatible.
Use wine vinegar for descaling the water heater, 
this being introduced into the appliance via the 
water supply. Allow the product to react and 

then thoroughly flush out the appliance with 

plenty of fresh water. For sterilization purposes 
we recommend ‘Certisil-Argento’; other 
products (especially those containing chlorine) 
are unsuitable and may damage the unit.
To avoid microorganisms colonizing the water 
in the boiler, heat the water to 70° C at regular 
intervals (at least once per year).

Move the rotary switch on the control panel 

to position (c – summer operation) 60° C. The 
green (b) and yellow (g) LEDs light up.
Once the water in the boiler has reached a 
temperature of 60° C, the burner will switch 
off and the yellow LED (g) will go out. The unit 
must stay switched on for at least 30 minutes 

and no warm water may be removed. The 
residual heat in the heat exchanger will heat the 
water up to 70° C.

fuses

The unit’s fuse is located on the electronics 

under the connection cover. Replace the unit’s 

fuse only with an identical fuse.
Device fuse: 10 A – slow – (T 10 A)

disposal

The liquid gas heater must be disposed in 
accordance with the administrative stipulations 
of the respective country in which it is used. 

National regulations and laws (in Germany, 
for example, the Altfahrzeug-Verordnung (old 

vehicle directive) must be observed.
In other countries, the relevant regulations must 
be observed.

Heating with drained water system

Set the rotary switch to the operational setting 
‘d’. Turn the rotary switch (a) to the desired 
thermostat setting (1 – 5). The green LED (b) 
for operation is lit and simultaneously indicates 
the position of the selected room temperature. 
The yellow LED (g) will be lit only when the 
temperature of the unit is below 5° C!
The unit automatically selects the required 
power level according to the temperature 
difference between the setting on the control 
panel and the current room temperature. After 
reaching the room temperature set on the 
control panel, the burner will switch off.

SwItcHInG off

Use the rotary switch to switch off heater 
(position f). The green LED (b) goes off.
If the green LED (b) blinks after switching off, 
then the unit’s after-running is active in order to 
reduce the unit’s temperature. This will end after 
a few minutes and the green LED (b) will go off.

always drain water contents if there is a risk 
of frost!

If the appliance is not to be used for a prolonged 

period, close the quick-acting valve in the gas 
supply line and turn off the gas cylinder.

red Led ‘failure’ 

The red LED (h) will be lit if there is a failure.
Please consult the Trouble-Shooting list for 
possible causes.

Reset (failure reset) the unit by switching it off 

and back on.
If the window switch is opened, the heating 
unit will stop operating and the red LED (h) will 
blink. Once the window switch is closed, the 
heating unit will continue operation and the 
green LED (b) will be lit continuously.

filling the water heater

Check if the rotary switch for the drain valve 
(FrostControl) is set to ‘Operation’, meaning 
that it is parallel to the water connection  
and engaged.
When the temperature at FrostControl is below 
about 7° C, first switch on the heater to warm 
the installation compartment and FrostControl. 
After several minutes, when the temperature at 
FrostControl is above 7° C, the drain valve can 
be closed.
Close the drain valve by pushing the push 
button until it engages. Switch on power for 

water pump (main switch or pump switch).
Open hot water taps in kitchen and bathroom, 
(set preselecting mixing taps or single-lever 
fittings to ‘hot’). Leave the fittings open for  
as long as it takes for the boiler to displace  

the air and fill up, and the water to flow 

without interruption.
If just the cold water system is being operated, 
without using the water heater, the heater tank 
also fills up with water. To avoid frost damage, 
the boiler must be drained through the drain 
valve, even if it was not operated. As an 
alternative, two shutoff valves, resistant to hot 
water, can be fitted in front of the cold and hot 
water connection.
When connecting to a central water supply (rural 
or city mains), a pressure reduction valve must 
always be installed to prevent pressures above 
2.8 bar from developing in the water heater.

draining the water heater

Switch off power to water pump (main or  
pump switch).
Open hot water taps in kitchen and bathroom.
Turn the rotary switch on the drain valve  
(Frost Control) by 180° until it engages, 
whereby the push button moves out and the 
drain valve opens.
The boiler is now drained directly to the outside
