11.1 Check Points
11.2 The Shapes of the 3-Way Valve Caps of the Outdoor Unit Have Changed.
• Accompanying the changes in the shapes of the 3-way valve caps, the tightening method has also been
changed.
• Firmly tighten the 3-way valve caps by hand and then tighten them up by another 30 degrees or so (one-twelfth
of a full turn) using a spanner or adjustable spanner.

Instruction
12.1 Select the Best Location
12.1.1 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 2.3m.
12.1.2 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 obstrucles.
• Do not place any obstrucles 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:

The centre of installation plate should be at
more than 450 mm at right and left of the wall.
The distance from installation plate edge to
ceiling should more than 67mm.
From installation plate left edge to unit’s left side
is 74mm.
From installation plate right edge to unit’s right
side is 94mm.
