Seaside installation. Make sure the outdoor unit is NOT directly exposed to sea
winds. This is to prevent corrosion caused by high levels of salt in the air, which
might shorten the life of the unit.
Install the outdoor unit away from direct sea winds.
Example: Behind the building.
If the outdoor unit is exposed to direct sea winds, install a windbreaker.
▪ Height of windbreaker≥1.5×height of outdoor unit
▪ Mind the service space requirements when installing the windbreaker.

Strong winds (≥18km/h) blowing against the outdoor unit’s air outlet causes short
circuit (suction of discharge air). This may result in:
▪ deterioration of the operational capacity;
▪ frequent frost acceleration in heating operation;
▪ disruption of operation due to decrease of low pressure or increase of high
pressure;
▪ a broken fan (if a strong wind blows continuously on the fan, it may start rotating
very fast, until it breaks).
It is recommended to install a baffle plate when the air outlet is exposed to wind.
It is recommended to install the outdoor unit with the air inlet facing the wall and
NOT directly exposed to the wind.
