Maintenance
Materials in the device which come into contact with wa-
ter are suitable for use with drinking water (see manufac-
turer declaration: www.truma.com – Manufacturer Declaration).
– The Truma UltraRapid HWS must be descaled on a regular
basis (at least twice a year).
We recommend the use of suitable normal commercial
products for the cleaning, disinfection and care of the
Truma UltraRapid HWS. Products containing chlorine are
unsuitable.
– In order to avoid the colonization of micro-organisms, heat
up the Truma UltraRapid HWS to 70 °C at regular intervals.
– The drain valve (Fig. 2 - 3) and the P&T safety valve (Fig. 2
- 4) are to be operated regularly to remove lime deposits
and to ensure that they are not blocked. Frequency: every 6
month.
Fuses
The water heater 12 V fuse is on the PCB on the water heater.
Important note
Only replace the miniature fuse on the PCB with a fuse of the
same type: 1.6 A (slow action).
