418. For R410A models, when connecting the piping, do not use any existing (R22) pipes and flare nuts. Using such same maycause abnormally high pressure in the refrigeration cycle (piping), and possibly result in explosion and injury. Use only R410Amaterials.Thickness of copper pipes used with R410A must be more than 0.8mm. Never use copper pipes thinner than 0.8mm.It is desirable that the amount of residual oil is less than 40 mg/10m.19. During installation, install the refrigerant piping properly before run the compressor. (Operation of compressor without fixing refrigerationpiping and valves at opened condition will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injuryetc.).20. During pump down operation, stop the compressor before remove the refrigeration piping. (Removal of refrigeration piping whilecompressor is operating and valves are opened condition will cause suck-in of air, abnormal high pressure in refrigeration cycle and resultin explosion, injury etc.).21. After completion of installation or service, confirm there is no leakage of refrigerant gas. It may generate toxic gas when the refrigerantcontacts with fire.22. Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when the refrigerant contacts with fire.23. Do not insert your fingers or other objects into the unit, high speed rotating fan may cause injury.24. Must not use other parts except original parts describe in catalog and manual.1. Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding ofthe unit, it may cause fire.2. Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage thefurniture.3. Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, after a long period, the flare maybreak and cause refrigerant gas leakage.4. Do not touch outdoor unit air inlet and aluminium fin. It may cause injury.5. Select an installation location which is easy for maintenance.6. Pb free solder has a higher melting point than standard solder; typically the melting point is 50°F - 70°F (30°C - 40°C) higher. Please use ahigh temperature solder iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F (370 ± 10°C). Pb free solderwill tend to splash when heated too high (about 1100°F / 600°C).7. Power supply connection to the air conditioner. Connect the power supply cord of the air conditioner to the mains using one of the followingmethods.Power supply point shall be the place where there is 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.i. Power supply connection to the receptacle using a power plug. Use an approved 15/16A (3/4~1.75HP), 16A (2.0HP), 20A (2.5HP) or25A (3.0HP) power plug with earth pin for the connection to the socket.ii. Power supply connection to a circuit breaker for the permanent connection. Use an approved 16A (3/4~2.0HP), 20A (2.5HP) or 25A(3.0HP) circuit breaker for the permanent connection. It must be a double pole switch with a minimum 3.0 mm contact gap.8. Do not release refrigerant during piping work for installation, servicing, reinstallation and during repairing a refrigerant parts.Take care of the liquid refrigerant, it may cause frostbite.9. Installation or servicing work: It may need two people to carry out the installation or servicing work.10. Do not install this appliance in a laundry room or other location where water may drip from the ceiling, etc.11. Do not sit or step on the unit, you may fall down accidentally.12. Do not touch the sharp aluminium fins or edges of metal parts.If you are required to handle sharp parts during installation or servicing, please wear hand glove.Sharp parts may cause injury.
