Operating instructions

Always observe the operating instructions and "Impor-
tant 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 the warning information, which is enclosed with the
appliance, to a place in the ve hicle where it is clearly visi ble to
all users (e.g. on the ward robe door)! Ask Truma to send you
stickers, if necessary.
Before using for the first time, it is essential to flush the
entire water supply through with clean warm water.
Always mount the cowl cap when the water heater is not be-
ing operated! Drain the water heater if there is a risk of frost!
There shall be no claims under guarantee for damaged
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).

Filling the water heater

Check that 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 fittings set to "hot".
Switch on power for water pump (main switch or pump switch).
Leave the tap open to let air escape while the water heater is
filling. The heater is filled when water flows out of the tap.
Residues of frozen water can prevent filling if there is a frost.
The water heater can be defrosted by switching on the heater
for a short period (max. 2 minutes). 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 or 14 litres).

Switching on Gas operation

c
d
a = Rotary switch "On (Gas operation)"
b = Rotary switch "Off"
c = Rotary knob for temperature selection
(lit via the green LED "Operating")
d = Red LED "Failure"
Never operate the water heater without water in it!
Remove cowl cap.
Open gas cylinder and open quick-acting valve in the gas
supply line.
Switch on the boiler using the rotary switch (a) on the ope-
rating part, the green LED lights up. Set the desired water
temperature at the rotary knob (c – steplessly adjustable from
about 30 °C to 70 °C).
When using the vehicle switches: refer to operating instruc-
tions of the vehicle manufacturer.
If there is air in the gas supply line, it may take up to a minute
before the gas is available for combustion. If the appliance
switches to "Failure" during this period, switch off the appli-
ance – wait 5 minutes – and switch on again!

Switching off

Switch the boiler off at the rotary switch (b). Mount cowl cap.
Drain the water heater if there is a risk of frost. Close quick-
acting valve in the gas supply line if the appliance is not to be
used for a longer period of time and close the gas cylinder.

Red LED "Failure"

In the event of a failure, the red LED (d) lights up. Causes can
be e.g. insufficient gas, air inside the gas piping system or re-
sponse of the overtemperature sensor has responded etc. To
unlock, switch off the appliance, wait 5 minutes, and switch
on again.
Opening a window to which a window switch is
attached and closing it again is the equivalent of switch-
ing the equipment off and on again at the control panel
(e.g. a fault reset)!
