4.3.3 Checking the heat exchanger
After a long time of use dust may build up in the exchanger and block the airflow. It is important to clean the exchanger
regularly (once a year) to maintain high efficiency. The heat exchanger can be taken out of the unit for maintenance
(figure 5).
Danger
• Risk of personal injury! The heat exchanger is heavy. There is a risk that the heat exchanger falls out of
the unit.
• Make sure to use proper lifting device or sufficient number of persons to lift the exchanger out of the
unit.
• The heat exchanger is sensitive for impacts. Handle with care.
