11.1. Select The Best Location
INDOOR UNIT
• There should not be any heat source or steam near the unit.
• There should not be any obstacles blocking the air
• 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,
• 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 2.5 m.
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.
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 10 m, additional refrigerant should be
added as shown in the table.
Example : For E24HK
If the unit is installed at a 20 m distance, the quantity of
additional refrigerant should be 300 g ...... (20 - 10) m x 30 g/m
= 300 g.
If the unit is installed at a 20 m distance, the quantity of
additional refrigerant should be 300 g ...... (20 - 10) m x 30 g/m
= 300 g.

HOW TO FIX INSTALLATION PLATE
The mounting wall is strong and solid enough to prevent it from

The centre of installation plate should be at more than 550 mm
at right and left of the wall.
The distance from installation plate edge to ceiling should more
than 67 mm.
From installation plate left edge to unit’s left side is 47 mm.
From installation plate right edge to unit’s right is 73 mm.

From installation plate left edge to unit’s left side is 47 mm.
From installation plate right edge to unit’s right is 73 mm.
1. Mount the installation plate on the wall with 5 screws or
more.
(If mounting the unit on the concrete wall consider using
anchor bolts.)

2. Drill the piping plate hole with ø70 mm hole-core drill.
• Line according to the arrows marked on the lower left
and right side of the installation plate. The meeting point
of the extended line is the centre of the hole. Another
method is by putting measuring tape at position as
shown in the diagram above. The hole centre is obtained
by measuring the distance namely 150 mm and 125 mm
for left and right hole respectively.
