Safety Cautions
Warning !
Do not touch the fins on the heat exchanger with bare hands:they are sharp and dangerous.
In the event of a refrigerant gas leak, provide adequate ventilation to the room.
If leaked refrigerant gas is exposed to a heat source, noxious gases may form.
With
Direct expesure to outdoor air may present a health hazard, and it may also cause food items to deteriorate.
When installing the unit in a small room, safeguard against hypoxia that results from leaked refrigerant reaching the threshold level.
Consult the dealer for necessary measures to take.
When relocating the air conditioner, consult the dealer or a specialist.
Improper installation may result in water leak, electric shock, or fire.
After completing the service work, check for a refrigerant gas leak.
If leaked gas refrigerant is exposed to a heat source such as fan heater,stove,and electric grill, noxious gases may form.
Do not try to defeat the safety features of the devices, and do not change the settings.
Defeating the safety features on the unit such as the pressure switch and temperature switch or using parts other than the dealer or specialist may result in fire or explosion.
Only use specified parts.
Have the unit professionally installed. Improper installation may cause water leak, electric shock,smoke, or fire.
Precautions for handling Units for Use with R410A
Caution!
Do not use the existing refrigerant piping
The old refrigerant and refrigerator oil in the existing piping contain a large amount of chlorine, which will cause the refrigerator oil in the new unit to deteriorate.
R410A is a
Keep the inner and outer surfaces of the pipes clean and free of contaminants such as sulfur, oxides, dust/dirt shaving particles, oils,and moisture.
Contaminants inside the refrigerant piping will cause the refrigerant oil to deteriorate.
Use a vacuum pump with a
If other types of valves are used, the vacuum pump oil will flow back into the refrigerant cycle and cause the refrigerator oil to deteriorate.
Do not use the following tools that have been used with the conventional refrigerants. prepare tools that are for exclusive use with R410A.
(Gauge manifold, charging hose, gas leak
If refrigerant and/or refrigerant oil left on these tools are mixed in with R410, or if water is mixed with R410A, it will cause the refrigerant to deteriorate.
Since R410A does not contain chlorine,
