Install air ducting
There are no obstacles in the 2000mm above the outdoor unit; When there are obstacles in the outer plane,
there must be a pilot channel, and the wind will be free, the wind will not beshort-circuited, and the external static
pressure will be less than 110Pa. Airway design dimensions are as follows:
Channel size (pattern 1)
AV08~14IMVURA
A The inner diameter 980 The inner diameter 1410
B The inner diameter750
C ≤10000
D E+750
E ≥300
F ≥320
Channel size (pattern 2)
AV08~14IMVURA
A The inner diameter 750 The inner diameter 750
B The inner diameter 980 The inner diameter 1410
C ≤10000
D E+980
E ≥300
F ≥320
Note:
Before installing the wind channel, the unit should be removed from the wind protection network. At the same time,
the outdoor air tube static press is set up to "have static pressure" mode. The above is just an example, the length
of the wind tunnel should be calculated according to the shape of the wind channel.
