Check and Clean a Heat Exchanger

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 im-
portance for the upkeep of a high efficiency that the ex-
changer block is removed from the unit and cleaned
periodically as described below. Clean the heat exchanger
at least every 3 years or when required.
1. Stop the unit by disconnecting the mains.
2. Open the front hatch. See chapter 3.2.
3. Pull out the exchanger using the strap at the front.
4. Gently vacuum the heat exchanger.
5. Remount the heat exchanger.
6. Close and lock the front hatch and connect the unit to
mains.

Check and Clean Fans

Warning
• All though the mains supply to the unit has been disconnected there is still risk of injury due to rotating
parts that have not come to a complete standstill.
Warning
• Beware of sharp edges during mounting and maintenance. Use protective gloves.
Fans are removed differently in left and right version of the unit.
