Operating
instructions
Always observe the op-
erating instructions and
„Important operating
notes" prior to starting!
The vehicle owner is respon-
sible for the correct opera-
tion of the appliance.
The installer or vehicle owner
must apply the yellow sticker
with the warning informa-
tion, 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
first time, it is essential
to flush the entire water sup-
ply through with clean warm
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 guaran-
tee for damage caused by
frost! Also drain the water
prior to repair or mainte-
nance work on the vehicle
(in the workshop!) as the
electrical safety/drain valve
opens when the appliance is
switched dead.
Electrical
safety/drain valve
m = Control knob „closed"
n = Control knob „drain"
The safety/drain valve is
held closed by a elec-
trical coil. To save battery
power, we recommend to
open the valve if the vehicle
is not in use for a prolonged
period!
If the temperature at the
safety/drain valve is less than
4°C, the water contents may
discharge on its own ac-
cord if the appliance is not
in operation (also if there is a
failure)! To avoid water loss,
switch the device on (sum-
mer or winter operation) and
close the safety/drain valve at
the actuating button by rais-
ing it up (position m).
Without heater operation, the
safety/drain valve can only be
closed again at temperatures
above 8°C!
The draining socket of the
electrical safety/drain valve
must always be kept clear
(free from slush, ice, leaves
etc.)! There shall be no
claims under guarantee
for damage caused by
frost!
Filling the water
heater
1. Close electrical safety/drain
valve at the control knob by
lifting up (position m).
At temperatures of around
8°C and less, switch on the
heater or water heater first,
to make sure the valve does
not open again!
2. Switch on power for water
pump (main switch or pump
switch).
3. Open hot water taps in
kitchen and bathroom, (set
preselecting mixing taps or
single-lever fittings to „hot").
Leave taps open until the
water heater has forced out
air and filled up with water
and water is flowing out of
the taps.
If just the cold water
system is being oper-
ated, without using the water
heater, the heater tank also
fills up with water. In order
to avoid damage by frost,
the water contents must be
drained by operating the
safety/drain valve, also when
the water heater has not
been used. 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 pres-
sure reduction valve must
always be installed to pre-
vent pressures above 2.8 bar
from developing in the water
heater.
Draining the
water heater
1. Interrupt power for water
pump (main switch or pump
switch).
2. Open hot water taps in
kitchen and bathroom.
3. Open electrical safety/
drain valve at control knob by
pressing in (position n).
The water heater content is
now emptied to the outside
through the safety/drain
valve. Place a bucket be-
neath the outlet to check
whether the water content
has completely drained away
(12 litres). There shall be no
claims under guarantee
for damage caused by
frost!

Room thermostat
i
i = Room temperature
sensor
To measure the room tem-
perature, an external room
temperature sensor (i) is
located in the vehicle. The
location of the sensor is
determined individually by
the vehicle manufacturer,
depending on the vehicle
type; consult the operating
instructions for your vehicle
for further details.
The thermostat setting on
the control panel (1 – 9) must
be determined individually
depending on the heating re-
quirement and the type of
vehicle. For an average room
temperature of about 23°C,
we recommend a thermostat
setting of about 6 – 8.
Taking into
operation
1. Check that the cowl is not
obstructed. Always remove
any covers, open deck cowl
on boats.
In winter, if a roof cowl is fit-
ted, it is recommended that a
cowl extension be fitted (see
Accessories). This must be
removed when the vehicle
is on the move. To run the
cowl through the roof on a
caravan, a cowl extension
piece is likewise used, which
must be fixed to the roof
with clamp rings (see Acces-
sories).
2. Turn on gas cylinder and
open quick-acting valve in
the gas supply line.
Heating operation
is basically possible
without restriction with or
without water content.
Summer operation
(hot water only)
Set the rotary switch to
Summer operation (c), 40°C
or 60°C.
Once the water temperature
which has been set (40°C or
60°C) has been reached, the
burner will switch off and the
yellow monitor lamp (g) will
go out.
Winter operation
(Heating with
water temperature
monitoring)
1. Set the rotary switch to the
operational setting „e".
2. Set the rotary switch (a)
to the desired thermostat
setting (1 – 9). The green
indicator lamp (b) illuminates
and indicates the room
temperature setting.
The device automatically
selects the setting that is
required in accordance with
the difference between the
temperature setting and the
current room temperature.
