Installation Guidelines
Where a wall or other obstacle is in the path of outdoor unit’s intake or exhaust airflow, follow the installation guidelines below.
For any of the below installation patterns, the wall height on the exhaust side should be 1200mm or less.
Precautions on Installation
Check the strength and level of the installation ground so that the unit will not cause any operating vibration or noise after installed.
In accordance with the foundation drawing, fix the unit securely by means of the foundation bolts. (Prepare four sets of M8 or M10
foundation bolts, nuts and washers each which are available on the market.)
It is best to screw in the foundation bolts until their length are 20mm from the foundation surface.
