Maintenance
Note: The water tank in the
Truma-Ultrastore is made of
high quality food-proof stain-
less steel VA.
Use wine vinegar for de-scal-
ing the water heater, this be-
ing introduced into the appli-
ance via the water supply. Al-
low the product to react and
then thoroughly flush out the
appliance with plenty of fresh
water. To sterilise the water
we recommend „Certisil-Ar-
gento”. Other products, par-
ticularly those containing
chlorine are unsuitable.
In order to avoid the prolifera-
tion of micro-organisms, heat
the Ultrastore to 70°C at reg-
ular intervals.
Do not use the water as
drinking water!
Fuses
The water heater fuse is on
the electronic control unit on
the water heater.
Important note: Only re-
place the miniature Fuse on
the p.c.b. with a fuse of the
same type: 1.6 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-Ultra-
store control p.c.b.'s as spare
parts!
while. Remedial action here
is to immediately run the
heater and to ensure ade-
quate room ventilation.
7. Items sensitive to heat
(e.g. spray cans) must not be
stored in the installation area,
since excess temperatures
may under certain circum-
stances be incurred there.
8. If the burner makes an un-
usual noise or if the flame
lifts off, it is likely that the
regulator is faulty and it is
essential to have it checked.
9. 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 cylin-
der gas installation that is
only accessible from the out-
side, the Truma Triomatic au-
tomatic reserve switch-over.
The Truma regulators have
been specially designed for
heavy duty use in caravans,
boats and vehicles. In addi-
tion 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 cylin-
ders by hand, using great
care! For temperatures
around 0°C and below, the
regulators should be operat-
ed with a defroster system
(Eis-Ex). Inspect regulator
connection hoses regularly
for signs of weakness.
For winter operation only use
special frost-resistant hoses.
Gas cylinders must always
stand upright!
General safety
notes
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 the appliances!
- close gas cylinder!
- open the windows!
- do not operate any
electrical switches!
- have the entire system
checked by an expert!
Repair jobs are only
to be carried out by
an expert.
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 can-
celling 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 30 mbar (or
28 mbar butane/37 mbar
propane) and must corre-
spond to the operating pres-
sure of the appliance (see da-
ta 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 al-
ways responsible for ar-
ranging the inspection.
4. In other countries, the
respectively valid regulations
must be observed. For your
own safety it is absolutely
necessary to have the com-
plete gas installation regularly
checked by an expert (at least
every 2 years).
5. Do not operate the water
heater when refuelling the ve-
hicle 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
