Units should be installed by licensed contractor
according to local code requirements.
Note:
• The dimensions indicated in the arrows (
show the required space to guarantee performance of
the air conditioner. Install the outdoor unit where the
maximum possible space can be provided, considering
later relocation, services, or repairs.
• The cooling/heating performance and the efficiency of
power usage may fall about 10% at the place where short
cycle is likely occur due to poor ventilation. Installing the
air outlet guide (optional) can improve performances.
• If air from the outlet blows against the wall, it may cause
stains on the wall.
Drain piping for outdoor unit
Install the unit horizontally.
Do not use drain socket in cold regions. Drain may freeze and make the fan stop.
The outdoor unit produces condensate during the heating operation. Select the installation place to ensure to prevent
the outdoor unit and/or the grounds from being wet by drain water or damaged by frozen drain water.
