Before touching electric terminal parts, turn off power switch.
When service panels are removed, live parts can be easily touched by accident.
Never leave the unit unattended during installation or servicing when the service panel is removed.
Do not touch water pipes during and immediately after operation as the pipes may be hot and could burn your
hands. To avoid injury, give the piping time to return to normal temperature or be sure to wear protective gloves.
Do not touch any switch with wet fingers. Touching a switch with wet fingers can cause electrical shock.
Before touching electrical parts, turn off all applicable power to the unit.
DANGER
Tear apart and throw away plastic packaging bags so that children will not play with them.Children playing with
plastic bags face danger of death by suffocation.
Safely dispose of packing materials such as nails and other metal or wood parts that could cause injuries.
Ask your dealer or qualified personnel to perform installation work in accordance with this manual. Do not install the
unit yourself. Improper installation could result in water leakage, electric shocks or fire
Be sure to use only specified accessories and parts for installation work. Failure to use specified parts may result in
water leakage, electric shocks, fire, or the unit falling from its mount.
Install the unit on a foundation that can withstand its weight. Insufficient physical strength may cause the equipment
to fall and possible injury.
Perform specified installation work with full consideration of strong wind, hurricanes, or earthquakes. Improper
installation work may result in accidents due to equipment falling.
Make certain that all electrical work is carried out by qualified ersonnel according to the local laws and regulations
and this manual using a separate circuit. Insufficient capacity of the power supply circuit or improper electrical
construction may lead to electric shocks or fire.
Be sure to install a ground fault circuit interrupter according to local laws and regulations. Failure to install a ground
fault circuit interrupter may cause electric shocks and fire.
Make sure all wiring is secure. Use the specified wires and ensure that terminal connections or wires are protected
from water and other adverse external forces. Incomplete connection or affixing may cause a fire.
When wiring the power supply, form the wires so that the front panel can be securely fastened. If the front panel is
not in place there could be overheating of the terminals, electric shocks or fire.
After completing the installation work, check to make sure that there is no refrigerant leakage.
Never directly touch any leaking refrigerant as it could cause severe frostbite.Do not touch the refrigerant pipes
during and immediately after operation as the refrigerant pipes may be hot or cold, depending on the condition of
the refrigerant flowing through the refrigerant piping, compressor and other refrigerant cycle parts. Burns or frostbite
are possible if you touch the refrigerant pipes. To avoid injury, give the pipes time to return to normal temperature
or, if you must touchthembe sure to wear protective gloves.
Do not touch the internal parts (pump, backup heater, etc.) during and immediately after operation. Touching the
internal parts can cause burns. To avoid injury, give the internal parts time to return to normal temperature or, if you
must touch them, be sure to wear protective gloves.
WARNING
Ground the unit.
Grounding resistance should be according to local laws and regulations.
Do not connect the ground wire to gas or water pipes, lightning conductors or telephone ground wires.
Incomplete grounding may cause electric shocks.
- Gas pipes
：
Fire or an explosion might occur if the gas leaks.
- Water pipes
：
Hard vinyl tubes are not effective grounds.
- Lightning conductors or telephone ground wires
：
Electrical threshold may rise abnormally if struck by a lightning
bolt.
Install the power wire at least 3 feet (1 meter) away from televisions or radios to prevent interference or noise.
(Depending on the radio waves, a distance of 3 feet (1 meter) may not be sufficient to eliminate the noise.)
Do not wash the unit. This may cause electric shocks or fire. The appliance must be installed in accordance with
national wiring regulations. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent
or similarly qualified persons in order to avoid a hazard.

NOTE
About Fluorinated Gasses
- This air-conditioning unit contains fluorinated gasses. For specific information on the type of gas and the amount,
please refer to the relevant label on the unit itself. Compliance with national gas regulations shall be observed.
- Installation, service, maintenance and repair of this unit must be performed by a certified technician.
- Product uninstallation and recycling must be performed by a certified technician.
- If the system has a leak-detection system installed, it must be checked for leaks at least every 12 months. When
the unit is checked for leaks, proper record-keeping of all checks is strongly recommended.
Do not install the unit in the following places:
- Where there is mist of mineral oil, oil spray or vapors. Plastic parts may deteriorate, and cause them to come loose
or water to leak.
- Where corrosive gases (such as sulphurous acid gas) are produced. Where corrosion of copper pipes or soldered
parts may cause refrigerant to leak.
- Where there is machinery which emits electromagnetic waves. Electromagnetic waves can disturb the control
system and cause equipment malfunction.
- Where flammable gases may leak, where carbon fiber or ignitable dust is suspended in the air or where volatile
flammables such as paint thinner or gasoline are handled. These types of gases might cause a fire.
- Where the air contains high levels of salt such as near the ocean.
- Where voltage fluctuates a lot, such as in factories.
- In vehicles or vessels.
- Where acidic or alkaline vapors are present.
This appliance can be used by children 8 years old and above and persons with reduced physical, sensory or mental
capabilities or lack of experience and knowledge if they are supervised or given instruction on using the unit in a
safe manner and understand the hazards involved. Children should not play with the unit. Cleaning and user mainte-
nance should not be done by children without supervision.
Children should be supervised to ensure that they do not play with the appliance.
If the supply cord is damaged, it must be replaced by the manufaturer or its service agent or a similarly qualified
person.
DISPOSAL: Do not dispose this product as unsorted municipal waste. Collection of such waste seperatelly for
special treatment is necessary. Do not dispose of electrical appliances as municipal waste, use seperate collection
facilities. Contact your local goverment for information regarding the collection systems available. If electrical
appliances are disposed of in landfills or dumps, hazardous substance can leak into the groudwater and get into the
food chain, damaging your health and well-being.
The wiring must be performed by professional technicians in accordance with national wiring regulation and this
circuit diagram. An all-pole disconnection device which has at least 3mm seperation distance in all pole and a
residualcurrent device(RCD) with the rating not exceeding 30mA shall be incorporated in the fixed wiring according
to the national rule.
Confirm the safety of the installation area ( walls, floors, etc. ) without hidden dangers such as water, electricity, and
gas.Before wiring/pipes.
Before installation , check whether the user's power supply meets the electrical installation requirements of unit (
including reliable grounding , leakage , and wire diameter electrical load, etc. ). If the electrical installation require-
ments of the product are not met, the installation of the product is prohibited until the product is rectified.
When installing multiple air conditioners in a centralized manner, please confirm the load balance of the three-phase
power supply, and multiple units are prevented from being assembled into the same phase of the three-phase power
supply.
Product installation should be fixed firmly, Take reinforcement measures, when necessary.
In order to ensure the safety of the product, please restart the unit at least once every 3 months, so that the unit can
carry out self-inspection operation.
