This Air Guide prevents reverse rotation of outdoor unit fan when it enters low speed rotation mode with fan controller being operated. It is
also used for protection of fan when strong winds, such as in typhoon, wind blowing through tall buildings, etc., strike directly the air outlet.
In addition, installation of this product is necessary when cooling operation is to be performed in outside-air temperature of -5° C or lower
(down to -15°C).
Pay attention to the following points when installing this product:
1) To eliminate the effects of external winds, be sure to install this unit with back surface facing wall side.
2) Do not install this unit in such orientation where wind blows directly at the back of the unit.
3) Installation of this product will reduce the capacity of the unit (approx. 2 or 3%) and increase the noise of outdoor unit (approx 1 or 2dB)
4) Do not use this product where there is any obstacle at either side or above the outdoor unit (discharged air will be blocked). This may
cause a short cycle.
