Maintenance
Do not modify this appliance
Servicing should only be carried out by authorised personnel.
Only original Truma parts may be used for maintenance and repair work!
Please contact the Service Australia for service and repairs.
Decalcificaon
The Truma UltraRapid must be descaled on a regular basis (at least twice a year).
We recommend the use of suitable normal commercial products for the cleaning, disinfecon and care of the
Truma UltraRapid. Products containing chlorine are unsuitable.
• In order to avoid the colonization of micro-organisms, heat up the Truma UltraRapid 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 acon).
Circuit Breaker
There is a circuit breaker allocated to the water heater circuit switch on the main electrical panel. To reset this
breaker, push in.
Water Pumps
The pump when switched on is acvated by the release of pressure at the tap and will pump water connuously unl the
tap is turned off and pressure restored. Should the pumps acvate while the taps is turned off this could indicate a leak
and require invesgaon and recficaon.
