Operating Instructions
Always observe the operating instructions and “Important
operating notes” prior to starting!
The vehicle owner is responsible for the correct
operation of the appliance.
The installer or vehicle owner must apply the yellow
sticker with warning information, which is enclosed with
the appliance, to a place in the vehicle where it is clearly
visible to all users (e.g. on the wardrobe door)! Ask
Truma to send you stickers if necessary.
Before using for the rst time it is essential
to ush the entire water supply system
through with clean water. If the heater is not
being used, always drain the water contents
if there is a risk of frost. There shall be no
claims under guarantee for damage caused by frost.
Materials in the device which come into contact
with water are suitable for use with drinking water
(see manufacturer declaration : www.truma.com –
Manufacturer Declaration).
Room Thermostat
To measure the room temperature, an external room
temperature sensor (s) is located in the vehicle. The
location of the sensor is determined individually by the
vehicle manufacturer depending on the vehicle type;
consult the operation instructions for your vehicle for
further details.
s
S = Room temperature sensor
The thermostat setting on the control panel (1-5) must
be determined individually depending on the heating
requirement and the type of vehicle. For an average
room temperature of about 23 degrees we recommend a
thermostat setting of about 4.
Safety/drain valve (operational)
Filling the water heater
Check the safety/drain valve in the cold water intake is
closed. Lever should be in horizontal position, position
e.
E = Lever position “closed”
F = Lever position “drain”
Open hot tap in bathroom or kitchen with pre-selecting
mixing taps or single-lever ttings set to “hot”.
Switch on power for water pump (main switch or pump
switch)
Leave tap open to let air escape while the water heater
is lling. The heater is lled when water ows out of the
tap.
Residues of frozen water can prevent lling if there is a
frost. The water heater can be defrosted by switching
on the heater for a short period. Frozen pipes can be
defrosted by heating the room.
Draining the water heater
If the caravan is not used during the winter the
boiler must be drained
Disconnect power for water pump (main switch
or pump switch).
Open hot water taps in bathroom and kitchen.
Open safety/drain valve : Lever in vertical position,
position F.
The water heater is now drained directly to the outside
via the safety/drain valve. Check that the water contents
have been completely drained (10 litres).
Closing the drain valve
Check if the rotary switch is set to “Operation” (position
T), meaning that is it parallel to the water connection
