Indoor Unit Installation
It is recommended to install the refnet joint before installing the indoor unit.
◆ Ensure that the ceiling is strong enough to support
the weight of the indoor unit.
Before hanging the unit, test the strength of each
attached suspension bolt.
◆ If the length of suspension bolt is more than 1.5m,
it is required to prevent vibration.
IMPORTANT
You must install the suspension bolts more than four
when installing the indoor unit.
