released to the outside from the room during operation

in cooling mode and that the heat introduced into the

room during operation in heat pump mode is taken from

the outside.

The dimensions and weights of the outdoor unit are

shown on Figures 5.4, 5.5 and Table 5.2, depending on

the model (please consult the model nameplate).
