1 Safety Precautions
• Read the following “SAFETY PRECAUTIONS” carefully before perform any servicing.
• Electrical work must be installed or serviced by a licensed electrician. Be sure to use the correct rating of the power plug and
main circuit for the model 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 or servicing due to ignoring of the instruction will cause harm or damage, and
the seriousness is classified by the following indications.
• The items to be followed are classified by the symbols:
• Carry out test running to confirm that no abnormality occurs after the servicing. Then, explain to user the operation, care and
maintenance as stated in instructions. Please remind the customer to keep the operating instructions for future reference.
This indication shows the possibility of causing death or serious injury.
This indication shows the possibility of causing injury or damage to properties.
This symbol denotes item that is PROHIBITED from doing.
1. Engage dealer or specialist for installation and servicing. If installation or servicing done by the user is defective, it will cause water
leakage, electrical shock or fire.
2. Install according to this installation instruction strictly. If installation is defective, it will cause water leakage, electrical shock or fire. 
3. Use the attached accessories parts and specified parts for installation and servicing. Otherwise, it will cause the set to fall, water leak-
age, fire or electrical shock.
4. Install at a strong and firm location which is able to withstand the set’s weight. If the strength is not enough or installation is not prop-
erly done, the set will drop and cause injury.
5. For electrical work, follow the local national wiring standard, regulation and the installation instruction. An independent circuit and sin-
gle outlet must be used. If electrical circuit capacity is not enough or defect found in electrical work, it will cause electrical shock or
fire.
6. Use the specified cable and connect tightly for indoor/outdoor connection. Connect tightly and clamp the cable so that no external
force will be acted on the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the connection.
7. Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will
cause heat-up or fire at the connection point of terminal, fire or electrical shock.
8. When connecting the piping, do not allow air or any substances other than the specified refrigerant to enter the refrigeration cycle.
Otherwise, this may lower the capacity, cause abnormally high pressure in the refrigeration cycle, and possibly result in explosion and
injury.
9. Thickness of copper pipes used must be more than 0.8 mm. Never use copper pipes thinner than 0.8 mm.
10. It is desirable that the amount of residual oil is less than 40 mg/10m.
11. Do not modify the length of the power supply cord or use of the extension cord, and do not share the single outlet with other electrical
appliances. Otherwise, it will cause fire or electrical shock.
1. The equipment must be earthed. It may cause electrical shock if grounding is not perfect.
2. Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding of the
unit, it may cause fire.
3. Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage
the furniture.
4. Pb free solder has a higher melting point than standard solder; typically the melting point is 50 - 70
qF (30 - 40qC) higher. Please use
a high temperature solder iron. In case of the soldering iron with temperature control, please set it to 700 ± 20
qF (370 ± 10qC).
Pb free solder will tend to splash when heated too high (about 1100
qF / 600qC).

ATTENTION
1. Selection of the installation location. Select an installation location which is rigid and strong enough to support or hold the unit, and select a
location for easy maintenance.
2. Power supply connection to the conditioner. Connect the power supply cord of the air conditioner to the mains using one of the following
methods.
Power supply point shall be the place where there is ease for 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 power plug with earth pin for the connection to the
socket.
2. Power supply connection to a circuit breaker for the permanent connection. Use an approved circuit breaker for the permanent connec-
tion. It must be a double pole switch with a minimum 3.5 mm contact gap.
3. Do not release refrigerant during piping work for installation, servicing, 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.
5. Do not install this appliance in a laundry room or other location where water may drip from the ceiling, etc.
