T R U M A ULTRASTORE
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, 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 the
Truma Service on Tel: 01283 586020.
Electrical Operating Instructions
1. Ensure that the heater tank is full of water
before operating the unit on electric power.
2. Turn on the electric heating element by
operating the water heater switch on the
power supply unit. See page 69.
3. At the Ultrastore control (Fig 4.), move the
rocker switch from the central off position
(h), to either 850W or 1300W (g). The 850W
setting will take longer to heat the water, but
less power than the 1300W setting.
4. Once a setting has been selected, the
electric element within the water heater will
turn ON and OFF automatically, to aim to
regulate the water temperature at 70°C.
As long as there is a suitable mains supply
present, and the water system is primed,
there is no requirement to switch the water
heater 230V element off.

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 oper-
ated with gas and electrical power.
The electrical heating rod is fitted with an
excess temperature cut-out. In the event of
a fault, switch off at the operating element.
Check water content, refill if required (close
drain valve). Wait 10 minutes, then switch
on again.
Maintenance
We recommend the Truma system care set
for cleaning, disinfecting and looking after the
boiler. Other products – in particular products
containing chlorine – are unsuitable.
To avoid infestation by micro-organisms, the
water content must be heated to 70 °C at
regular intervals. Clean the device and the
ventilation slits with a dry and fluff free cloth.
Fuses
The water heater 12 V fuse is on the electronic
control unit on the water heater.
Note: Only replace the miniature Fuse on
the p.c.b. with a fuse of the same type: 1.6
A, EN 60127-2-3 (slow action).
