Precautions for group control system or two remote 
controller control system

This system provides two other control systems beside individual
control (one remote controller controls one indoor unit) system.
Confirm the following if your unit is of the following control system
type.

■

Group control system
One remote controller controls up to 16 indoor units.

PTIMUM

OPERATION

Observe the following precautions to ensure the system operates
properly.

■

Adjust the air outlet properly and avoid direct air flow to room
inhabitants.

■

Adjust the room temperature properly for a comfortable
environment. Avoid excessive heating or cooling.

■

Prevent direct sunlight from entering a room during cooling
operation by using curtains or blinds.

■

Keep doors and windows closed. If the doors and windows
remain open, room air will flow out and decrease the effect of
cooling and heating.

■

Never place objects near the air inlet and the air outlet of the
unit. It may retard effectiveness or cause operation to stop.

■

Turn  off the main power supply switch when not using for long
periods of time. Electricity is consumed as long as the switch is
on. Turn off the main power supply switch in order to save
energy. Turn on the main power supply switch 6 hours before
restarting operation in order to ensure smooth operation. (Refer
to 

"Maintenance" on page 4

.)

When the display shows "
