insulation material (6 mm thick expanded polystyrene
or expanded neoprene). Fireproofing classification: M1)
IF THE ABOVE INSTRUCTIONS ARE NOT
FOLLOWED, CONDENSATE LEAKS MAY OCCUR.
Distributing air to an adjacent room requires one or two of
the corresponding ducts' air distribution flaps to be closed.
