4. The impact of seasonal winds should be considered when choosing a location for the outdoor unit. Do not allow the
prevailing wind to blow directly into the inlet or outlet of the unit.
5. Must be arranged to follow the following principles in the exhaust duct.
• Install exhaust duct before the unit is taken out of the wind protection network, otherwise it will affect the output of
the unit. This can lead to a decline in performance, and even cause failure.
• Air outlet louvers may be used, Do not exceed a 15° angle or 3.25 in gap above the air inlet.
• Ducting the outlet fan is allowed but do not use more than one 90° elbow. This can result in a high static drop.
• Installation of a flex connector to eliminate noise and vibration between an outlet duct and the outdoor unit is highly
recommended.
• Exhaust air ducts must be independently installed in multi unit installations. Do not combine the outlet of multiple units
together.
