Concrete foundation
• Foundation could be on flat and it is recommended to be 100-300 mm higher than ground level.
• Install a drainage around foundation for smooth drain.
• When installing the outdoor unit, fix it by M10 anchor bolts.
• When installing the unit on a roof or a veranda, drain water sometimes turns into ice on a cold morning. Therefore, avoid
draining in an area that people often use because it may become slippery.
