11. Installation Instruction (E9RK and E12RK)
11.1 Select the Best Location
11.1.1 Indoor Unit
Do not install the unit in excessive oil fume area
such as kitchen, workshop and etc.
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 8 ft (2.4 m).
11.1.2 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 [piping length for
additional gas], additional refrigerant should be
added as shown in the table.
Recommended installation height for outdoor unit
should be above the seasonal snow level.
Example: For E9RKUAW
If the unit is installed at 32.8 ft (10 m) distance, the
quantity of additional refrigerant should be 1.64 oz
(50 g) .... (32.8 - 24.6) ft x 0.2 oz/ft = 1.64 oz.
((10 -7.5) m x 20 g/m = 50 g).

11.2 Indoor Unit
11.2.1 How to Fix Installation Plate
The mounting wall shall be strong and solid enough to prevent it from the vibration.
The center of installation plate should be at more than cat right and left of the wall.
The distance from installation plate edge to ceiling should more than d.
From installation plate left edge to unit’s left side is e.
From installation plate right edge to unit’s right side is f.
ƻ
B : For left side piping, piping connection for liquid should be about gfrom this line.
: For left side piping, piping connection for gas should be about hfrom this line.
1 Mount the installation plate on the wall with 5 screws or more (at least 5 screws).
(If mounting the unit on the concrete wall, consider using anchor bolts.)
oAlways mount the installation plate horizontally by aligning the marking-off line with the thread and using
a level gauge.
2 Drill the piping plate hole with ø2 3/4" (ø70 mm) hole-core drill.
oLine according to the left and right side of the installation plate. The meeting point of the extended line is
the center of the hole. Another method is by putting measuring tape at position as shown in the diagram
above. The hole center is obtained by measuring the distance namely 5 1/16" (128 mm) for left and right
hole respectively.
oDrill the piping hole at either the right or the left and the hole should be slightly slanting to the outdoor
side.
11.2.2 To Drill a Hole in the Wall and
Install a Sleeve of Piping
1 Insert the piping sleeve to the hole.
2 Fix the bushing to the sleeve.
3 Cut the sleeve until it extrudes about 19/32"
(15 mm) from the wall.
4 Finish by sealing the sleeve with putty or
caulking compound at the final stage.
