2.3 Important
information
Air in the cold water pipe will destroy the bare-wire heating system of the MTH. If the water supply to
the MTH has been interrupted, for example due to the risk of frost or work on the water pipe, the fol-
lowing steps must be carried out before the system is used again:
the MTH has been interrupted, for example due to the risk of frost or work on the water pipe, the fol-
lowing steps must be carried out before the system is used again:
1. Disconnect supply or disconnect the fuses.
2. Open a hot water tap downstream of the device for as long as it is necessary for the device and the cold
water pipe to be freed of air.
3. Reconnect the supply or connect the fuses again.
All information in these Instructions for Use and Installation must be followed carefully. They provide impor-
tant information with regard to safety, operation, installation, and maintenance of the device.
