5.2. Fresh air mode
Cold air is drawn in from the outside, heated and blown into the boat's
interior. This renews the cabin air and reduces humidity. Ensure there are
enough ventilation openings in the cabins! A room temperature sensor
must be installed for temperature control, preferably in the saloon. In
summer, ventilation is also possible (when comfort control element is
used).
 Draw in cold air directly from lockers or rudder boxes if they are dry,
clean and free of odours and exhaust gases.
For proper ventilation, ensure the intake diameter = 1.5 x hose diame-
ter of the heater.
 Otherwise, use an intake hose for intake from the outside.
 Prevent water from entering through the intake opening.
