Collective / Continuous Installation for roof top use
Space required for collective installation and continuous installation: When installing several units, leave space
between each block as shown below considering passage for air and people.

L ≤ H
Seasonal wind and cautions in winter
• Sufficient measures are required in a snow area or severe cold area in winter so that product can be operated well.
• Get ready for seasonal wind or snow in winter even in other areas.
• Install a suction and discharge duct not to let in snow or rain.
• Install the outdoor unit not to come in contact with snow directly. If snow piles up and freezes on the air suction hole,
the system may malfunction. If it is installed at snowy area, attach the hood to the system.
• Install the outdoor unit at the higher installation console by 50cm than the average snowfall (annual average snowfall) if
it is installed at the area with much snowfall.
1. The height of H frame must be more than 2 times the snowfall and its width shall not exceed the width of the
product. (If width of the frame is wider than that of the product, snow may accumulate)
2. Don't install the suction hole and discharge hole of the Outdoor Unit facing the seasonal wind.
