4.4 To clean the heat exchanger
Danger
• Make sure that the Mains supply to the unit is disconnected before performing any maintenance or
electrical work!
Warning
• Risk of personal injury! The heat exchanger weighs about 14 kg. There is a risk that the heat exchanger
falls out of the unit.
• Make sure that small children are not beneath the unit when the heat exchanger is removed!
Warning
• Beware of sharp edges during mounting and maintenance. Use protective gloves.
Even if the required maintenance is carried out, dust will build up in the exchanger block. It is therefore of vital impor-
tance for the upkeep of a high efficiency that the exchanger block is removed from the unit and cleaned periodically as
described below. Clean the heat exchanger at least every 3 years or when required.
