When connecting to a central water supply
(rural or city mains), a pressure reduction valve
must always be installed to prevent pressures
above 2.8 bar from developing in the water
heater.
Draining the water heater
Switch off power to water pump (main or
pump switch).
Open hot water taps in kitchen and bathroom.
Turn the rotary switch on the drain valve
(Frost Control) by 180° until it engages,
whereby the push button moves out and the
drain valve opens.
The boiler is now drained directly to the
outside via the drain valve. Place a bucket
beneath the outlet to check whether the
water content has completely drained away
(10 litres). There shall be no claims under
guarantee for damage caused by frost!
Maintenance
Only original Truma parts may be used for
maintenance and repair work!
The water container used is made of stainless
steel, which is foodstuff-compatible.
Use wine vinegar for descaling 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

werecommend‘Certisil-Argento’;other
products (especially those containing chlorine)
are unsuitable and may damage the unit.

in the boiler, heat the water to 70° C at regular
intervals (at least once per year).
Move the rotary switch on the control panel
to position (c – summer operation) 60° C. The
green (b) and yellow (g) LEDs light up.
Once the water in the boiler has reached a
temperature of 60° C, the burner will switch
off and the yellow LED (g) will go out. The unit
must stay switched on for at least 30 minutes
and no warm water may be removed. The
residual heat in the heat exchanger will heat
the water up to 70° C.
Fuses
The unit’s fuse is located on the electronics
under the connection cover. Replace the unit’s
fuse only with an identical fuse.
Device fuse: 10 A – slow – (T 10 A)
Disposal
The liquid gas heater must be disposed in
accordance with the administrative stipulations
of the respective country in which it is used.
Nationalregulationsandlaws(inGermany,

vehicle directive) must be observed.
In other countries, the relevant regulations
must be observed.
