1. SAFETY PRECAUTIONS
▪ The “SAFETY PRECAUTIONS” indicated in this manual contain impor-
tant information pertaining to your safety. Be sure to observe them.
▪ Request the user to keep this manual on hand for future use, such as
for relocating or repairing the unit.
This mark indicates procedures which, if improp-
WARNING
Perform electrical work by an authorized service personnel in accordance
with this manual and the electrical wiring regulations or implementation
regulations of the country. Also do not install this product by yourself.
Improper electric work will cause electric shock or a fi re.
Perform installation work in accordance with this manual. Request an
authorized service personnel to perform installation work. Do not install
this product by yourself. Improper installation will cause injury, electric
shock, fi re, etc.
In the event of a malfunction (burning smell, etc.), immediately stop
operation, turn off the electrical breaker, and consult authorized service
personnel.
Do not install the unit in the following areas:
▪ Do not install the unit near a source of heat, steam or fl ammable gas.
▪ Area fi 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 fail 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 interfer-
ence. 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 fi bers or fl ammable dust, or volatile infl ammables such as paint
thinner or gasoline. If gas leaks and settles around the unit, it can
cause a fi re.
▪ Install the unit in a well-ventilated place avoiding rains and direct sun-
light.
Do not operate this product 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.
erly performed, might lead to the death or serious
injury of the user.

CAUTION
Pay abundant care when transporting this product because it is a precision device. Improper transportation will cause trouble.
Do not touch the switches with sharp objects. Doing so will cause injury,
trouble, or electric shock.
Do not expose this product directly to water. Doing so will cause trouble,
electric shock, or heating.
Do not set vessels containing a liquid on this product. Doing so will cause
heating, fi 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.
NOTES:
This product is manufactured to metric units and tolerances.
United States customary units are provided for reference only. In cases
where exact dimensions and tolerances are required, always refer to
metric units.

5. WIRING
WARNING
Before starting installation work, turn off the power of this product and
the connection destination. Do not turn on the power again until installation is completed. Otherwise, it will cause electric shock or fi re.
Use the accessories or specifi ed connection cable. Do not modify power
supply cable and connection cables other than those specifi ed, do not
use extension cables, and do not use independent branch wiring. It may
cause electric shock or fi re.
Install the connection cables securely to the terminal block. Confi rm that
external force of the cable is not applied to the terminal block. Use the
specifi ed cables. If intermediate connection or insertion fi xing are imper-
fect, it will cause electric shock, fi re, etc.
When connecting the connection cable, route the cables so that the
cover of this product is securely fi xed. If the cover is imperfectly fi xed, it
may cause fi re or overheating of the terminals.
Perform earth (ground) work positively. Do not connect the earth (ground)
cable to a telephone cable, water pipe, or conductor rod.
Perform all wiring works so that the user does not touch the wiring.
Otherwise it 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 fi re.
CAUTION
Do not bind the remote controller cable and the external input cable
together with or parallel to the power supply cable of the indoor and
outdoor units. 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, fi re, or electric shock.
Install the indoor unit, outdoor unit, power supply cable, transmission
cable and remote control cable at least 40 in (1 m) away from a television
or radio.
The purpose of this is to prevent TV reception interference or radio noise.
(Even if they are installed more than 40 in (1 m) apart, you could still
receive noise under some signal conditions.)
Perform wiring so that water does not enter this product along the external wiring. Always install a trap to the wiring or take other countermeasures. Otherwise it will cause trouble or electric shock or fi re.
Confi rm 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 fi re.
When installing the connection cables near a source of electromagnetic
waves, use shielded cable.
Otherwise, a breakdown or malfunction could result.
The terminal screws and earth (ground) screws have different shapes.
Be sure to install the screws in the correct locations. If the screws are
installed in the wrong locations, the circuit board could be damaged.
