There shall be no claim un-
der 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 indi-
cation is, for example, no gas
available or air in the gas sup-
ply 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 con-
tact the Truma Service (please
refer to the last page)

Electrical operating
instructions
Attention:
Never operate the
water heater without water in
it!
Switch on at the control pan-
el (g). The indicator lamp indi-
cates that the electrical water
heating is switched on.
Attention:
The water tempera-
ture cannot be selected, auto-
matic temperature limitation at
approx. 70°C! For a faster heat-
ing up period the appliance can
be simultaneously operated
with gas
and
electrical power.
Note:
The electrical heating
element is fitted with an ex-
cess temperature cut-out. In
the event of a fault, switch off
at the control panel, wait
5 minutes, then switch on
again.
Filling the Truma-
Ultrastore 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 fit-
tings 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 con-
tents must be drained by ac-
tuating the safety/ drain valve,
also when the heater has not
been used. As an alternative,
two shut-off valves, resistant
to hot water, can be fitted in
front of the cold and hot wa-
ter 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, po-
sition (f).
4. The water heater is now
drained directly to the outside
via the safety/drain valve.
Check that the water con-
tents have been completely
drained (10 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 direct-
ly 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 tem-
perature at rotary knob (b) in-
finitely 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-ob-
servance of this point can
lead to the function of the ap-
pliance being impaired
through water, dirt or in-
sects), close quick-acting
valve in the gas supply line
and close the gas cylinder.

Operating
instructions
Always observe the oper-
ating 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 visi-
ble to all users (e.g. on the
wardrobe door)! Ask Truma to
send you stickers, if neces-
sary.
Attention:
Before using for
the first time, it is essential to
flush the entire water supply
through with clean warm wa-
ter. 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
damaged caused by frost!
When connecting to a central
water supply (rural or city
connection) or when using
more powerful pumps, a
pressure reducer must be
used which prevents pres-
sures of greater than 2.8 bar
occurring in the Ultratore.
