Servicing
Use wine vinegar for de-sca-
ling the water heater, this
being introduced into the ap-
pliance 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 “Certi-
sil-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 microorga-
nisms, we recommend hea-
ting 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 elec-
tronics, return the control
p.c.b. well padded. If you fail
to pack it correctly the guar-
antee 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 hea-
ter splitting. Continuous lea-
kage of water from the valve
may indicate a problem with
the water heater!
- Water may drip drom the
discharge pipe of the pres-
sure relief device and this
pipe must be left open to the
atmosphere.
- The pressure relief device is
to be operated regularly to re-
move lime deposits and to ve-
rify that it is not blocked.
- Any discharge pipe connec-
ted to the pressure relief de-
vice is to be installed in a
2
must be observed. For your
own safety it is absolutely
necessary to have the com-
plete gas installation regular-
ly 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 adequa-
te room ventilation.
7. If the burner makes an un-
usual noise or if the flame
lifts off, it is likely that the re-
gulator is faulty and it is es-
sential to have it checked.
For the gas system only gas
pressure regulators with pro-
tection against excess pres-
sure, 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 cylin-
der gas installation that is
only accessible from the out-
side, the Truma Triomatic or
Duomatic automatic reserve
switch-over. The Truma regu-
lators have been specially de-
signed for heavy duty use in
caravans, boats and vehicles.
In addition to a safety valve
for countering excess pres-
sure, they also have a pres-
sure gauge with which you
can check that the installati-
on is fully gas tight.
Always connect the pressure
regulators to the gas cylin-
ders by hand, using great
care! For temperatures
around 0°C and below, the
regulators should be opera-
ted 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 direc-
tion and in a frost free am-
bient.
- 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 en-
sure all supply circuits are dis-
connected (i.e. 230 - 240 V
and 12 V) and gas supply is
securely turned off.
- Any work involving connec-
tion or interconnecting wiring
must be conducted by a licen-
sed 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 ex-
pert.
1. Any alteration to the appli-
ance (including cowl) or the
use of spare parts and acces-
sories which are important for
the functioning of the heater
and which are not original
Truma parts, as well as the
non-observance of the instal-
lation and operating instruc-
tions, shall lead to the cancel-
ling 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 corres-
pond to the operating pres-
sure 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 cer-
tificate in accordance with the
DVGW-form G 607. The
vehicle owner is always res-
ponsible for arranging the
inspection.
4. In other countries, the re-
spectively valid regulations
