When the outdoor unit fan enters low speed rotation mode with the fan controller turned on, this Snow Guard prevents reverse rotation. It is also used to protect the fan when strong winds, such as a typhoon or wind blowing through tall buildings, strike the air outlet directly. Furthermore, installation of this product is required when cooling operations are to be carried out in outside-air temperatures of -5°C or lower (down to -15°C).
When installing this product, pay special attention to the following:
- Install this unit with the back surface facing the wall side to eliminate the effects of external winds.
- This unit should not be installed in such a way that the wind blows directly at the back of the unit.
- The installation of this product will reduce the unit’s capacity by approximately 2% – 3% and increase the outdoor unit’s noise level by approximately 1dB – 2dB.
- Use this product only if there is no obstruction on either side or above the outdoor unit (discharge air will be blocked). This could result in a short cycle.
