7.2 CLEANING THE HEAT EXCHANGER
Every year, verify that the fin pack is not clogged from dust or anything else that does
not allow the normal airflow; if necessary, use a jet of compressed air to clean the heat
exchanger. To prevent damage to the fins, or the pipes on the heat exchanger, never use
steel tools or sharp objects to clean the spaces between the fins. The access to the fin pack
is possible only after having disconnected the unit from the power mains and after removing
the filter.
