4WARNING19. 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 or 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 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 described in catalog and manual.25. Using of refrigerant other than the specified type may cause product damage, burst and injury etc.CAUTION1. Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding of theunit, 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 damagethe furniture.3. Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, after a long period, the flaremay break 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 usea high 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 room air conditioner.Power supply cord shall be UL listed or CSA approved 3 conductor with minimum AWG12 wires.Power supply point should be in an easily accessible place for power disconnection in case of emergency.In some countries, permanent connection of this air conditioner to the power supply is prohibited.Fix power supply connection to a circuit breaker for permanent connection.Use NRTL approved fuse or circuit breaker (rating refers to name plate) for permanent connection.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 aluminum 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.
