Installation Instruction
Install Air Ducting
Ensure there are no obstacles for 2000mm above the outdoor unit. When there are obstacles in the outer plane, there
must be a pilot channel to avoid the short circuit of the wind flow and to maintain the external static pressure less than
110Pa. The airway design dimensions are as follows:
Channel size (pattern 1)

Note:
The outdoor air tube static press should be set up to the 'have static pressure' mode. The above is just an example;
the length of the wind tunnel should be calculated as per the shape of the wind channel.
