(to change air blowing direction)
* 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 a typhoon, wind blowing through tall
buildings, etc., directly strike the air outlet. In addition, installation of this product is necessary when cooling opetation
is to be performed in outdoor tempreture of -5℃ or lower (down to -15℃).
Note the followings when installing this guide:
1) Be sure not to use "upward discharge" in a place where snowing is possible. Snow may accumulate in the
guard, which could damage the fan, etc.
2) Attaching this unit will decrease the performance (by 2-3%) and increase noise from outdoor unit (by approx. 1-2 dB).
3) Do not use "upward discharge" when there are any obstacles at the back and on both sides of outdoor unit
(air is taken in from top of unit): This could cause a short cycle.
4) To eliminate the influence of external wind, be sure to install the unit with its back facing to wall.
5) Do not install this unit in a place where wind directly blows to the back of the unit.
CAUTION
When the outdoor unit is installed in front of a store or in a passage, this air outlet guide is used to change the discharge direction of
hot air (during cooling) or cold air (during heating) from the outdoor unit.
Upward, downward and sideways directions are possible. This guide is also effective to protect the
winds may blow against the discharge outlet.
