12.1. Safe ty P re cautions
•
Read the following “S A F E TY P RE C A U TIO N S ” carefully before installation.
•
E lectrical work must be installed by a licensed electrician. Be sure to use the correct rating of the power plug and main circuit
for the model to be installed.
•
The caution items stated here must be followed because these important contents are related to safety. The meaning of each
indication used is as below. Incorrect installation due to ig noring of the instruction will cause harm or damag e, and the
seriousness is classified by the following indications.
WA RN IN G
This indication shows the possibility of causing death or serious injury.
CA U T IO N
This indication shows the possibility of causing injury or damag e to properties only.
The items to be followed are classified by the symbols:
S ymbol with backg round white denotes item that is P RO H IBITE D from doing .
•
C arry out test running to confirm that no abnormality occurs after the installation. Then, ex plain to user the operation, care and
maintenance as stated in instructions. P lease remind the customer to keep the operating instructions for future reference.
WA RN IN G
1 . E ng ag e dealer or specialist for installation. If installation done by the user is defectiv e, it will cause water leakag e, electrical shock or fire.
2. Install according to this installation instruction strictly. If installation is defectiv e, it will cause water leakag e, electrical shock or fire.
3 . U se the attached accessories parts and specified parts for installation. O therwise, it will cause the set to fall, water leakag e, fire or
electrical shock.
4 . Install at a strong and firm location which is able to withstand the set’s weig ht. If the streng th is not enoug h or installation is not properly
done, the set will drop and cause injury.
5 . F or electrical work, follow the local national wiring standard, reg ulation and this installation instruction. A n independent circuit and sing le
outlet must be used. If electrical circuit capacity is not enoug h or defect found in electrical work, it will cause electrical shock or fire.
6 . U se the specified cable (1 .5 mm2) and connect tig htly for indoor/outdoor connection. C onnect tig htly and clamp the cable so that no
ex ternal force will be acted on the terminal. If connection or fix ing is not perfect, it will cause heat-up or fire at the connection.
7 . Wire routing must be properly arrang ed so that control board cov er is fix ed properly. If control board cov er is not fix ed perfectly, it will
cause heat-up at connection point of terminal, fire or electrical shock.
8 . When carrying out piping connection, take care not to let air substances other than the specified refrig erant g o into
refrig eration cycle. O therwise, it will cause lower capacity, abnormal hig h pressure in the refrig eration cycle, ex plosion
and injury.
9 . When connecting the piping , do not allow air or any substances other than the specified refrig erant (R4 1 0 A ) to enter the
refrig eration cycle. O therwise, this may lower the capacity, cause abnormally hig h pressure in the refrig eration cycle, and
possibly result in ex plosion and injury.
1 0 .
•
When connecting the piping , do not use any ex isting (R22) pipes and flare nuts. U sing such same may cause
abnormally hig h pressure in the refrig eration cycle (piping ), and possibly result in ex plosion and injury. U se only
R4 1 0 A materials.
•
Thickness of copper pipes used with R4 1 0 A must be more than 0 .8 mm. N ev er use copper pipes thinner than 0 .8
mm.
•
It is desirable that the amount of residual oil is less than 4 0 mg /1 0 m.
1 1 . D o not modify the leng th of the power supply cord or use of the ex tension cord, and do not share the sing le outlet with
other electrical appliances. O therwise, it will cause fire or electrical shock.

Power supply point shall be the place where there is ease for access for the power disconnection in case of emergency.
In some countries, permanent connection of this room air conditioner to the power supply is prohibited.
1. Power supply connection to the receptacle using a power plug.
Use an approved 16A (E18DK, E21DK) power plug with earth pin for connection to the socket.
2. Power supply connection to a circuit breaker for the permanent connection. Use an approved 16A circuit breaker for the permanent
connection. It must be a double pole switch with a minimum 3.5 mm contact gap.
3. Do not release refrigerant.
Do not release refrigerant during piping work for installation, reinstallation and during repairing a refrigeration parts. Take care of the
liquid refrigerant, it may cause frostbite.
4. Installation work.
It may need two people to carry out the installation work.

12.2.1. SELECT THE BEST LOCATION
(Refer to “Select the best location”
section)
12.2.2. HOW TO F IX INSTALLATION
PLATE
The mounting wall is strong and solid enough to prevent it from
the vibration.
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.
:
:
:
For left side piping, piping connection for liquid should be
about 126 mm from this line.
For left side piping, piping connection for gas should be
about 174 mm from this line.
For left side piping, piping connecting cable should be
about 984 mm from this line.
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.)
•
Always mount the installation plate horiz ontally by
aligning the marking-off line with the thread and using a
level gauge.
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.
•
Drill the piping hole at either the right or the left and the
hole should be slightly slanted to the outdoor side.
12.2.3 . TO DRILL A HOLE IN THE WALL
AND INSTALL A SLEEV E 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 15 mm from the wall.
Caution
When the wall is hollow, please be sure to use the
sleeve for tube ass’y to prevent dangers caused by
mice biting the connecting cable.
4. Finish by sealing the sleeve with putty or caulking
compound at the final stage.

shall be approved polychloroprene sheathed 4 × 1.5 mm
2
flexible cord, type designation 245 IEC 57 or heavier cord.
•
Ensure the color of wires of outdoor unit and the
terminal Nos. are the same to the indoor’s respectively.
•
Earth lead wire shall be longer than the other lead wires
as shown in the figure for the electrical safety in case of
the slipping out of the cord from the anchorage.
•
Secure the cable onto the control board with the holder

4. Pull the lower section of the front grille towards you to remove the front grille.
The below operations will be performed by pressing the “AUTO” switch.
1. AUTO OPERATION MODE
The Auto operation will be activated immediately once the Auto Switch is pressed.
2. TEST RUN OPERATION (FOR PUMP DOWN/SERVICING PURPOSE)
The Test Run operation will be activated if the Auto Switch is pressed continuously for more than 5 sec. A “beep” sound will
occur at the fifth sec., in order to identify the starting of Test Run operation
3. REMOTE CONTROLLER RECEIVING SOUND ON/OFF
The ON/OFF of remote controller receiving sound can be change over by pressing the following step:
a. Release the Auto Switch after Test Run operation is activated.
b. Then, within 20 sec., after a., press Auto Switch for more than 5 sec.
A “beep” “beep” sound will occur at the fifth sec., then release the Auto Switch.
c. Within 20 sec. after b., press Auto Switch again. Everytime Auto Switch is pressed (within 20 sec. interval), remote
controller receiving sound status will be reversed between ON and OFF.
