9.1 Select The Best Location
9.1.1 Indoor Unit
• There should not be any heat source or steam near the unit.
• There should not be any obstacles blocking the air circulation.
• A place where air circulation in the room is good.
• A place where drainage can be easily done.
• A place where noise prevention is taken into consideration.
• Do not install the unit near the door way.
• Ensure the spaces indicated by arrows from the wall, ceiling, fence
or other obstacles.
• Recommended installation height for indoor unit shall be at least
2.5m.
9.1.2 Outdoor Unit
• If an awning is built over the unit to prevent direct sunlight or rain,
be careful that heat radiation from the condenser is not obstructed.
• There should not be any animal or plant which could be affected by
hot air discharged.
• Keep the spaces indicated by arrows from wall, ceiling, fence or
other obstacles.
• Do not place any obstacles which may cause a short circuit of the
discharged air.
• If piping length is over the rated length, additional refrigerant should
be added as shown in the table below:
Example: For YW12MKD
If the unit is installed at a 10m distance, the quantity of additional refrigerant
should be 50 g.…… (10-7) m x 20g/m = 60 g

For left side piping, piping connection for gas should be about 154 mm from this line.
1 Mount the installation plate on the wall with 5 screws or more. (If mounting the unit on the wall, consider
using anchor bolts.) Always mount the installation plate horizontally by aligning the marking-off line with
the thread and using a level gauge.
