Maintenance

Only original Truma parts may be used for maintenance and
repair work.
The device must be descaled on a regular basis (at least twice
a year).
We recommend the Truma system care set for cleaning, dis-
infecting and maintenance of the boiler. Other products – in
particular products containing chlorine – are unsuitable.
The effectiveness of the use of chemicals to combat microor-
ganisms in the unit can be increased by heating the water in
the boiler to 70 °C at regular intervals.
– Set water temperature to 60 °C.
– Switch on device.
Once the water in the boiler has reached a temperature
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 removed. The residual heat in the heat exchanger will heat
the water up to 70 °C.

Fuses

The fuses are located in the electronic control unit, beneath
the connection cover. When replacing a fuse, be sure to use
the same type.
Device fuse: 10 A (slow-acting) (T 10 A)
Burner fuse: 20 A (slow-acting) 6.3 x 32 mm
