Switching off (gas operation):
Switch off the water heater at the rotary switch (b).
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 quickacting valve in the gas
supply line and close the gas cylinder.
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 indicator lamp (d) lights up if there is
a failure. The reason for such an indication is,
for example - cowl cover fitted, 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 Truma
Service on Tel: 01283 511092.
ELECTRICAL OPERATING INSTRUCTIONS
Attention: Do not operate the water heater
without water in it!
Press the switch on the fused spur to ON.
The indicator lamp indicates that the heater is
switched on.
Switch the electric supply on at the fuse spur
marked Water Heater, normally in the wardrobe.
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.
Note: The water tank in the Truma-Ultrastore
is made of high quality food-proof stainless
steel VA.
Use wine vinegar for de-scaling 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.
In order to avoid the proliferation of micro-
organisms, heat the Ultrastore to 70°C at
regular intervals.
Do not use the water as drinking water!
Important Operating Notes
1. If the cowl is positioned close to an opening
hatch (window), keep this closed during
operation. See warning plate. Always mount
the cowl cover if the heater is not being
used. Non-observation of this point can
lead to the function of the appliance being
impaired through water, dirt or insects.
2. The guarantee will be invalidated if this point
is not observed. Always remove the cowl
cover prior to operating the water heater!
3. If there is a defect in the electronics, return
the control Printed Circuit Board well
padded. If you fail to pack it correctly the
guarantee will be invalidated. Only use
original Truma Ultrastore control PCBs as
spare parts.
4. If just the cold water system is being used,
without water heating, the header tank
becomes more vulnerable to frost damage.
Accordingly the contents should be drained
by operating the safety/drain valve. This
also applies when the vehicle is in storage.
General safety notes
If the gas system is leaking or if there is a
smell of gas:
• Extinguish all naked flames.
• Do not smoke.
• Switch off the appliances.
