Step 3: Duct and accessories installation
NOTE:
1.Do not put the connecting duct weight
on the indoor unit.
2. When connecting the duct, use an
nonflammable canvas tie-in to prevent
vibrating.
3. Insulation foam must be wrapped outside the
duct to avoid condensate. An internal duct
underlayer can be added to reduce noise,
if the end-user requires.
Step 4: Control (only for inverter units)
The capacity of the system and the network
address of the air-conditioner can be set by
the switches on the indoor Main Control
Board.
Before setting, turn off the power. After
setting, restart the unit.
Setting is not allowed when the unit is
power on.

2. Install the canvas tie-in between the body and duct.
3. The air inlet and air outlet duct should be far
