7.2.3 CLEANING THE COIL
Every year, verify that the fin pack is not clogged from dust or anything else that does not allow
the normal air flow; 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.
