Always observe the operating instructions 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
vehicle where it is clearly
visible to all users (e.g. on the
wardrobe door)! Ask Truma to
send you stickers, if necessary.
Attention: Before using 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 being operated!
Drain the water heater if
there is a risk of frost! There
shall be no claims under
guarantee for damage caused by frost!
If connecting to a central
water supply (rural or city
connection) or when using
more powerful pumps, a
pressure reducer must be
used which prevents pressures of greater than 280 kPa
occurring in the Boiler.
Safety/drain valve
e = Lever position
"Closed"
f = Lever position
"Drain"
There shall be no claim
under guarantee if this
point is not observed.
Always remove the cowl
cover prior to operating the
water heater!
Red indicator lamp
“Failure“
The red indictor lamp (c)
lights up if there is a failure.
The reason for such an indication is, for example, no gas
available or air in the gas supply system, triggering of the
excess temperature monitor
etc. To unlock, switch off the
appliance, wait 5 minutes,
and switch on again.
In event of faults, always
contact the Truma Service
(please refer to page 9)

Electrical operating
instructions
Attention: Never operate
the water heater without
water in it!
Switch the switch (d) on the
control panel to „On“. The indicator lamp indicates that
the electrical water heating is
switched on.
Note: The water temperature
cannot be selected, automatic
temperature limitation at
approx. 70°C! For a faster
heating up period the appliance can be simultaneously
operated with gas and electrical power.
Filling the TrumaBoiler with water
1. Check that the safety/ drain
valve in the cold water intake
is closed: Lever should be in
horizontal position, position
(e).
2. Open hot tap in bathroom
or kitchen, with pre-selecting
mixing taps or single-lever fittings set to "hot".
3. 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.
Note: If just the cold water
system is being used, without water heater, the heater
tank is also filled up with
water. In order to avoid
damage through frost, the
water contents must be drained by actuating the safety/
drain valve, also when the
heater has not been used. As
an alternative, a shut-off valve
can be installed upstream of
the cold and hot water
connection.
Draining the water
heater
1. Disconnect power for
water pump (main switch or
pump switch).
2. Open hot water taps in
bathroom and kitchen.
3. Open safety/drain valve:
Lever in vertical position, position (f).
4. 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).

Gas operating
instructions
Attention: Never operate
the water heater without
water in it!
If the wall cowl is positioned
close to an opening window
(or hatch) - in particular directly under it - it must remain
closed when the water heater
is in use (see warning plate).
1. Remove cowl cover.
2. Open gas cylinder and
open quick-acting valve in the
gas supply line.
3. Select required water temperature at rotary knob (b) infinitely variable from approx.
30° to 70°C.
4. Switch on water heater at
the slide switch (a) on the
control panel, green indicator
lamp "Operation" lights up.
5. 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 appliance - wait
5 minutes - and switch on
again!
Switching off
(gas operation)
Switch off the water heater at
the slide switch (a).
Drain the water heater if
there is a risk of frost!
If the water heater is not to
be used for a longer period,
mount cowl cover (non-observance of this point can lead to
the function of the appliance
being impaired through water,
dirt or insects), close quick-acting valve in the gas supply
line and close the gas cylinder.

Servicing
Use wine vinegar for de-scaling 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. To sterilise the
water we recommend “Certisil-Argento”. Other products,
particularly those containing
chlorine are unsuitable.
Note: The water tank in the
Truma-Boiler is of high quality
food-proof stainless steel VA.
The plastic elbow water
connections and the
safety/drain valve fulfil the EC
guideline for food quality in
plastic parts (90/128/EEC).
However, In order to avoid
the colonization of microorganisms, we recommend heating up the tank to 70°C at
regular intervals and not using
the water as drinking water.
Fuses
The water heater fuse is on
the electronic control unit on
the water heater.
Important note: Only replace
the miniature Fuse on the
p.c.b. with a fuse of the same
type: 1,25 AT EN 60127-2-3
(slow action).
If there is a defect in the electronics, return the control
p.c.b. well padded. If you fail
to pack it correctly the guarantee shall no longer be valid.
Only use original Truma-Boiler
control p.c.b.'s as spare
parts!
General safety notes
Danger: Failure to operate
the relief valve easing gear at
least once every six months
may result in the water heater splitting. Continuous leakage of water from the valve
may indicate a problem with
the water heater!
- Water may drip drom the
discharge pipe of the pressure relief device and this
pipe must be left open to the
atmosphere.
- The pressure relief device is
to be operated regularly to remove lime deposits and to verify that it is not blocked.
- Any discharge pipe connected to the pressure relief device is to be installed in a
2
must be observed. For your
own safety it is absolutely
necessary to have the complete gas installation regularly checked by an expert (at
least every 2 years).
5. Do not operate the water
heater when refuelling the
vehicle and when in the
garage.
6. During the initial operation
of a brand new appliance (or
after it has not been used for
some time), a slight amount
of fumes and a slight smell
may be noticed for a short
while. Remedial action here
is to immediately run the
heater and to ensure adequate room ventilation.
7. If the burner makes an unusual noise or if the flame
lifts off, it is likely that the regulator is faulty and it is essential to have it checked.
For the gas system only gas
pressure regulators with protection against excess pressure, such as regulators with
safety valves according to
DIN 4811 and VP 306, may
be used. We recommend the
Truma DUB vehicle regulator
or in the case of a two cylinder gas installation that is
only accessible from the outside, the Truma Triomatic or
Duomatic automatic reserve
switch-over. The Truma regulators have been specially designed for heavy duty use in
caravans, boats and vehicles.
In addition to a safety valve
for countering excess pressure, they also have a pressure gauge with which you
can check that the installation is fully gas tight.
Always connect the pressure
regulators to the gas cylinders by hand, using great
care! For temperatures
around 0°C and below, the
regulators should be operated with a defroster system
(Eis-Ex). Inspect regulator
connec-tion hoses regularly
for signs of weakness.
For winter operation only use
special frost-resistant hoses.
Gas cylinders must always
stand upright!
continuously downward direction and in a frost free ambient.
- This unit is not to be used by
children or infirm persons
without proper supervision at
all times. Not to be used as a
toy.
- Before gaining access to any
and all terminals, please ensure all supply circuits are disconnected (i.e. 230 - 240 V
and 12 V) and gas supply is
securely turned off.
- Any work involving connection or interconnecting wiring
must be conducted by a licensed electrician.
In event of leaks in the gas
system or if there is a smell
of gas:
- extinguish all naked
flames!
- do not smoke!
- switch off all appliances!
- shut off the gas cylinder!
- open the windows and
doors!
- do not actuate any
electrical switches!
- have the entire system
checked by an expert!
Repairs may only be
carried out by an expert.
1. Any alteration to the appli-
ance (including cowl) or the
use of spare parts and accessories which are important for
the functioning of the heater
and which are not original
Truma parts, as well as the
non-observance of the installation and operating instructions, shall lead to the cancelling of the guarantee and
exclusion of liability claims. It
also becomes illegal to use
the appliance, and in some
countries this even makes it
illegal to use the vehicle.
2. The operating pressure for
the gas supply is 2.75 kPa
(propane) and must correspond to the operating pressure of the appliance (see
data plate).
3. In Germany only LPG
systems must comply with
the DVGW form G 607.
The gas system must be
tested every 2 years by a
liquid gas expert (DVFG, TÜV,
DEKRA). This inspection must
be confirmed on the test certificate in accordance with the
DVGW-form G 607. The
vehicle owner is always responsible for arranging the
inspection.
