Thoroughly read this installation manual before
use to ensure safety. The users should keep this
manual for future reference and refer to it as
necessary.
BACnet™ is a registered trade mark of ASHRAE
(American Society of Heating, Refrigerating, and
Air-Conditioning Engineers, Inc.).
Safety Precautions
• Thoroughly read the following safety precautions prior to installation.
• Observe these precautions carefully to ensure safety.
WARNING
CAUTION
• After reading this manual, pass the manual on to the end user to retain for future reference.
• The users should keep this manual for future reference and refer to it as necessary. This manual should be made available to those
who repair or relocate the units. Make sure that the manual is passed on to any future air condition system users.
Electric work must be performed by an authorized technician.
Indicates a risk of death or serious injury.
Indicates a risk of injury or structural damage.
WARNING
Installation
To reduce the risk of fire and electric shock, do not install
the units where they can get wet.
To reduce the risk of electric shock, fire, and malfunction,
do not install the unit in a steamy or condensing
environments.
Properly dispose of the packing materials.
Plastic bags can pose suffocation and choking hazards. Keep
out of the reach of children. Tear the plastics bags before
disposing of them.
Wire installation
Properly install the unit on a stable, load-bearing surface.
Unit installed on an unstable surface may fall and cause injury.
Units must be properly installed by your dealer or
authorized technician according to the instructions in the
Installation Manual.
Improper installation may result in electric shock or fire.
Properly secure the cables with clamps so that the weight
of the cables will not strain the connectors.
Improperly connected cables may break, produce heat, and
cause smoke or fire.
Electric work must be performed by an authorized
technician according to the local regulations and the
instructions detailed in this manual. Always use a
dedicated circuit.
Capacity shortage to the power supply circuit or improper
installation may result in electric shock, smoke, or fire.
Install all required covers.
Infiltration of dust or water may cause electric shock, smoke,
or fire.
Take appropriate measures against electrical noise
interference when installing the air conditioners in
hospitals or radio communication facilities.
• Inverter, power generators, or radio communication
equipment may interfere with the normal operation of the
unit.
• Subsequently, the device may also affect medical treatment,
image broadcasting by creating frequency noise.
Make sure that there is a main power switch and residual
current circuit breaker (RCCB) for each unit.
A ready accessible breaker for power source line helps reduce
the risk of electric shock. Installation of a breaker is mandatory
in some area.
To reduce the risk of electric leak, overheating, and fire,
only use standard cables with the proper current carrying
capacity.
Use properly rated breakers (residual current circuit
breaker (RCCB), main switch + fuse, circuit breaker).
The use of improperly rated breakers may result in
malfunctions or fire.
To reduce the risk of electric shock and malfunctions,
keep wire pieces and sheath shavings out of the terminal
block.
This appliance must be earthed.
Do not connect the protective earth cable to a gas pipe, water
pipe, lightning rod, or telephone earthing cable.
If the unit is not properly earthed, the unit may malfunction due
to electrical noise interference. It also poses a risk of electric
shock, smoke, or fire.

General caution
Do not install the unit in environments where large
amounts of oil (including machine) or acidic/alkaline
chemical sprays are present. These types of substances
may cause device performance to be reduced and cause
electrical shock, malfunction, smoke, or fire.
To reduce the risk of electric shock, fire, or malfunction,
do not wash the unit with water or other types of liquids.
Relocating/Repairing units
Consult your dealer or an authorized technician when the
unit needs to be relocated or repaired.
Do not disassemble the unit or make any modifications/
alterations to the unit.
Improper repair, modification, or alteration may cause injury,
electric shock, or fire.
Transporting units/Unit installation
Do not install the unit where there is a risk of leaking
flammable gas.
If flammable gas accumulates around the unit, it may ignite
and cause a fire or explosion.
Wear protective gloves.
A high voltage is applied to the terminals. To reduce the risk of
electric shock, wear protective gloves before touching the
electrical parts on the unit.
CAUTION
Take appropriate safety measures against earthquakes to
prevent the unit from toppling over.
Unit installed on an unstable surface may fall and cause injury.
Electric work
Do not touch switches or other electrical parts with wet
hands.
Doing so poses a risk of fire or electric shock.
General caution
To reduce the risk of electric shock, turn off the power
before performing electric work.
When replacing fuses, only use fuses with adequate
breaking capacity.
The use of improperly rated fuses or a substitution of fuses
with steel or copper wire may result in fire.
To avoid deformation and malfunction, do not install the
remote controller in direct sunlight or where the ambient
temperature exceeds 55°C (131°F) or drops below -10°C
(14°F).
Always use adequate tools for repair.
The use of unsuitable tools may result in failure to complete
the job properly and cause unit damage or injury.
To reduce the risk of injury, do not touch the edges of
parts.
To reduce the risk of injury from accidentally dropped
tools, check the surroundings before performing
installation, inspection, and repairs, and keep children
away from the site.
Important
To avoid malfunctions, do not bundle the power cable and
signal transmission lines together, or put them in the
same conduit.
To avoid fire, malfunction, and damage, do not connect
the power cable to terminal block for signal cables.
When connecting to the Internet, manage the security of
the Internet.
To prevent unauthorized access, always use a security device
such as a VPN router when connecting to the Internet.
