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 blocki
ng 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
c
onsiderat
ion.
Do not install the unit near the door way.
Ensure the spaces indicated by arrows from the
wall, ceili
ng, fence or other obstacles.
Recommended installation height for ind
oor 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
sunli
ght or rain, be careful that heat radiat
ion from
the con
denser is not obstructed.
There should not be any animal or plant which
coul
d be affected by hot air discharg
ed.
Keep the spaces indicated by arrows from
wall,
ceiling, fence or other obstacles.
Do not place any obstacles
which may cause a
sho
rt circuit of the discharged air.
If piping length is over the [piping length
for
addition
al gas], additional refrigerant sh
ould be
adde
d as shown in the tabl
e.
Recommended installation height for outdoor un
it
sho
uld be above the seasonal snow
level.
Example: For E9RKUA
W
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 c at 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 g from this line.
: For left side piping, piping connection for gas should be about h from 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.)
o Always mount the installation plate horizontally by aligning the marking-off line with the thread and us
ing
a level gaug
e.
2 Drill the piping plate hole with ø2 3/4" (ø70 mm) hole-core drill.
o Line according to the left and right side of the installation plate. The meeting point of the extended lin
e is
the cente
r of the hole. Another method is by putting measuring tape at position as sh
own in the diagram
above. The h
ole center is obtained by measuring the distance namely 5 1/16" (128 mm) fo
r left and right
hole re
specti
vely.
o
Drill the piping hole at either the right or the left and the hole should be slightly slanting to the outdoo
r
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.
