Installation example
1 Truma-Ultrastore
2 Control panels
3 Safety/drain valve
4 Cowl for combustion air
intake and exhaust gas
discharge
Important operating notes
If the cowl has been placed near or directly beneath an open-
ing window, the device must be equipped with an automatic
shut-off device in order to prevent operation with the window
open.
2. Always mount the cowl cap if the water heater is not being
used. Non-observance of this point can lead to the function of
the appliance being impaired through water, dirt or insects.
There shall be no claim under guarantee if this point is not
observed. Always remove the cowl cap prior to operating the
water heater!
3. 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, two shut-off
valves, resistant to hot water, can be fitted in front of the cold
and hot water connection.
Drain the water heater if there is a risk of frost!
There shall be no claim under guarantee if this point is
not observed.
4. If connecting to a central water supply (rural or city connec-
tion) or when using more powerful pumps, a pressure reducer
must be used which prevents pressures of greater than 2.8 bar
occurring in the Ultrastore.
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 be-
ing operated! Drain the water heater if there is a risk of frost!
There shall be no claims under guarantee for damage
caused by frost!
The installer or vehicle owner must apply the yellow sticker
with the warning information, which is enclosed with the appli-
ance, 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.
Maintenance
The water container used is made of VA stainless steel,
which is foodstuff-compatible.
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 recom-
mend Certisil Combina or Micropur Forte.
To avoid infestation by micro-organisms, the water content
must be heated to 70°C at regular intervals.
Do not use the water as drinking water!
Fuses
The water heater 12 V fuse is on the electronic control unit on
the water heater.
Only replace the minia-
ture Fuse on the p.c.b.
with a fuse of the same type:
1.6 A, 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-Ultrastore control p.c.b.'s as spare
parts!
