To ensure that the bare wire heating system is not dam-
aged following an interruption to the water supply, the
appliance must be restarted taking the following steps.
 Disconnect the appliance from the power supply by
removing the fuses/tripping the MCBs.
 Open the tap for one minute until the appliance and
its upstream cold water inlet line are free of air.
 Switch the mains power back ON again.
4.2 Temperature limit / Anti-scalding protection
The maximum outlet temperature for the appliance can be limited
to 43°C. For this, contact your local heating contractor.
5. Cleaning, care and maintenance
 Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
 Check the taps regularly. Limescale deposits at the tap out-
lets can be removed using commercially available descaling
agents.
