1. SAFETY PRECAUTIONS
The “SAFETY PRECAUTIONS” indicated in the manual contain important •
information pertaining to your safety. Be sure to observe them.
For details of the operation methods, refer to the operating manual.•
Request the user to keep the manual on hand for future use, such as for •
relocating or repairing the unit.
WARNING
This mark indicates procedures which, if improperly
performed, might lead to the death or serious injury
of the user.
CAUTION
This mark indicates procedures which, if improperly
performed, might possibly result in personal harm to
the user, or damage to property.
WARNING
For the air conditioner to operate satisfactorily, install it as outlined in this
installation manual.
Do not turn on the power until all installation work is complete.
Perform electrical work by an authorized service personnel in accordance
with the installation manual and the electrical wiring regulations or implementation regulations of the country. Improper electric work will cause
electric shock or a re.
Perform installation work in accordance with the installation manual.
Request an authorized service personnel to perform installation work.
Do not install this unit by yourself. Improper installation will cause injury,
electric shock, re, etc.
In the event of a malfunction (burning smell, etc.), immediately stop
operation, turn off the electrical breaker, and consult authorized service
personnel.
WARNING
Do not install the unit in the following areas:
Do not install the unit near a source of heat, steam, or ammable gas.•
Area lled with mineral oil or containing a large amount of splashed oil •
or steam, such as a kitchen. It will deteriorate plastic parts, causing the
parts to fall or the unit to leak water.
Area that generates substances that adversely affect the equipment, •
such as sulfuric gas, chlorine gas, acid, or alkali. It will cause the copper pipes and brazed joints to corrode, which can cause refrigerant
leakage.
Area containing equipment that generates electromagnetic interference. •
It will cause the control system to malfunction, preventing the unit from
operating normally.
Area that can cause combustible gas to leak, contains suspended •
carbon bers or ammable dust, or volatile inammables such as paint
thinner or gasoline. If gas leaks and settles around the unit, it can cause
a re.
Install the unit in a well-ventilated place avoiding rains and direct •
sunlight.
Do not operate this unit when your hands are wet.
Touching the unit with wet hands will cause an electric shock.
If children may approach the unit, take preventive measures so that they
cannot reach the unit.
CAUTION
When detecting the room temperature using the remote controller, please
set up the remote controller according to the following conditions. If the
remote controller is not well set, the correct room temperature will not
be detected, and thus the abnormal conditions like “not cooled” or “not
heated” will occur even if the air-conditioner is running normally.
Locate where is not be affected by inow of •
outside air such as caused by opening and closing a door.
Locate where an average temperature for the •
room being air-conditioned will be sensed.
Do not locate directly exposed to the outlet air •
from the air conditioner.
Locate out of direct sunlight.•
Locate away from the inuence of other heat •
sources.
Temperature sensor
Do not touch the remote controller PC board and PC board parts directly
with your hands.
Do not wire the remote controller cable and the bus wire together with or
parallel to the connection cables, transmission cables, and power supply
cables of the indoor and outdoor units. It may cause erroneous operation.
When installing the bus wire near a source of electromagnetic waves, use
shielded wire.
Do not set the DIP switches, either on the air conditioner or the remote
controller, in any way other than indicated in this manual or the manual
that is supplied with the air conditioner. Doing so may result in an improper operation.
Do not touch the switches with sharp objects. Doing so will cause injury,
trouble, or electric shock.
Do not expose this unit directly to water. Doing so will cause trouble,
electric shock, or heating.
Do not set vessels containing a liquid on this unit. Doing so will cause
heating, re, or electric shock.
Dispose of the packing materials safely. Tear and dispose of the plastic
packing bags so that children cannot play with them. There is the danger
of suffocation if children play with the original plastic bags.

5. INSTALLING THE REMOTE CONTROLLER
5.1. Wiring
WARNING
Before starting installation work, turn off the power of the connection
destination. Do not turn on the power again until installation is completed.
Otherwise, it will cause electric shock or re.
Use the accessories or specied connection cables.
Do not modify connection cables other than those specied, do not use
extension cords, and do not use independent branch wiring. The allow-
able current will be exceeded and cause electric shock or re.
Install the connection cables securely to the terminal block. Conrm that
external force is not applied to the wire. Use connection cables made
of the specied wire. If intermediate connection or insertion xing are
imperfect, it will cause electric shock, re, etc.
Do not connect functional earthing to a telephone functional earthing,
water pipe, or conductor rod.
Always fasten the outside covering of the connection cable with the cable
clamp. (If the insulator is chafed, electric leakage may occur.)
When performing cable wiring work, be sure that it does not touch the
user. Doing so will cause injury or electric shock.
If any cable is damaged, do not repair or modify it yourself. Improper work
will cause electric shock or re.
CAUTION
Do not parallel to the remote controller cables, indoor and outdoor
connection cable, and power supply cables. It may cause erroneous
operation.
When performing wiring work, be careful not to damage the cable or
injure yourself. Also, connect the connectors securely. Loose connectors
will cause trouble, heating, re, or electric shock.
Install the remote control cable 3ft. (1 m) away from television and radio
to avoid distorted images and noise.
Perform wiring so that water does not enter this unit along the external
wiring. Always install a trap to the wiring or take other countermeasures.
Otherwise it will cause trouble or electric shock or re.
Conrm the name of each unit and name of each terminal block of the
unit and connect the wiring in accordance with the directions given in the
manual so that there is no incorrect wiring. Incorrect wiring will damage
the electric parts and cause smoke and re.
When installing the connection cable near a source of electromagnetic
waves, use shielded cable. Otherwise, a breakdown or malfunction could
result.
5.2. Connection of remote controller cable
CAUTION
When connecting the remote controller cable to the wall mounted type
and the oor type indoor unit, do not connect it to the outdoor unit or the
indoor unit power terminal block. It may cause a failure.
There are 2 methods to connect the remote controller cable to the indoor
unit. One is the connection using contained connecting cable and the other
is the connection the remote controller cable is connected to the exclusive
terminal block of the indoor unit.
Exclusive terminal block for remote controller connection method is different
depending on each model. Modify the remote controller cable as per below
description and connect it.
(For the details, refer to the installation manual of the indoor unit to be used.)
5.2.1 When connecting to the wall mounted type
and the oor type connector
