OUTDOOR INSALLATION PRECAUTION
1
Install the outdoor unit on a rigid base to prevent increased noise levels and vibration.
Ensure the air outlet is not blocked by any objects such as plants or walls, etc.
If the installation location is exposed to strong winds, ensure the unit is placed lengthwise along
the wall or provide a switchable baffle to block strong wind gusts from entering the unit.
If suspending the unit with a bracket, follow the bracket manufacturer’s installation instructions.
Use a raised concrete pad or concrete blocks to provide a solid base and level surface - securely
anchor the unit down with bolts
In a snowy area, install the outdoor unit on a raised platform higher than drifting snow.
Se ttlemen t o f outdoor unit
Anchor the outdoor unit with a bolt and nut ( 10mm) or tightly and horizontally
on a concrete or rigid mount.
