NOTE
It is not necessary to designate indoor unit address
when using group control. The address is automatically
set when the power is activated.
Precautions
1.
A single switch can be used to supply power to units on the
same system. However, branch switches and branch circuit
breakers must be selected carefully.
2.
For a group control remote controller, choose the remote
controller that suits the indoor unit which has the most functions.
3.
Do not ground the equipment on gas pipes, water pipes,
lightning rods or crossground with telephones. Improper
grounding could result in electric shock.

NSTALLATION OF THE DECORATION PANEL
Refer to the installation manual delivered with the decoration panel.
After installing the decoration panel, ensure that there is no space
