Maintenance
Only original Truma parts may be used for maintenance and
repair work.
– Even outside the season, the heater should be operated
once a month for about ten minutes.
– Clean installation area at least once per year, and have unit
checked for soiling and cleaned by an expert if necessary.
– The drain valve must be actuated regularly (at least twice
per year) in order to remove limescale deposits and to ensu-
re that it is not blocked.
Biofilm, deposits and limescale must be removed using
chemicals to protect the unit from infestation by microorgan-
isms. Only chloride-free products must be used in order to
prevent damage to the unit.
The effectiveness of the use of chemicals to combat microor-
ganisms in the unit can be increased by heating the water in
the hot water system to 70 °C at regular intervals.
– Set water temperature to 60 °C.
– Switch on unit.
Once the water in the water heater has reached a tem-
perature of 60 °C, the burner will switch off. The unit
must stay switched on for at least 30 minutes and no warm
water may be withdrawn. The residual heat in the heat ex-
changer will heat the water up to 70 °C.
Fuses
The fuses are located in the electronic control unit, beneath
the connector cover. When replacing a fuse, be sure to use
the same type.
Device fuse: 10 A – slow – 5 x 20 mm (T 10 A)
Burner fuse: 20 A – slow – 6.3 x 32 mm
