NOTE:
*1. If the field-supplied snow protection hood or the air flow deflector duct is adopted, the space of minimum 50mm is required.
*2. Partly open a wall if the unit is surrounded by walls at four sides.
3. Keep the top of the outdoor unit without any obstacle to prevent short circuit due to inlet air and outlet air of each outdoor unit.
4. The above chart provides sufficient operation and maintenance space for outdoor unit under standard operation conditions.
(operating mode: cooling, ambient temperature: 35 degrees) If the outdoor unit ambient temperature is higher, and there is a outlet
air short circuit, adjust the installation size depending on the actual installation conditions, and the calculation of outdoor unit return
airflow.
5. When multiple outdoor units are installed in the same direction, you can install a maximum of six outdoor units. The minimum
distance between two adjacent outdoor units should be at least 1m.
