Installation of indoor unit
1. Install temporarily the indoor unit.
• Attach the hanging bracket to the hanging bolt.
Be sure to fix the hanging bracket from both up
and down sides of the hanging bracket by using
the nuts (M10 procured locally) and the washer.
2. Using nut, adjust height of the main unit.
3. Check the main unit is horizontally installed.
• Attach canvas ducts (procured locally) to the air
inlet and the air outlet so that vibration of the
main unit does not travel to the duct or ceiling.
Attach also acoustic-absorption material to the
inner liner of the duct and the vibration-proof
rubber to the hanging bolt.
