If air is mixed with the refrigerant, then it can be the cause of abnormal high pressure in
the refrigerant line, and may result in an explosion and other hazards.
The use of any refrigerant other than that specified for the system will cause mechanical
failure or system malfunction or unit breakdown. In the worst case, this could lead to a
serious impediment to securing product safety.
Prohibited
Do not install objects under the unit that cause trouble when they get wet.
(Drain blockage due to dust, high humidity (80 % or higher) or prolonged operation during air
conditioning may cause water to drip and get household belongings wet or dirty.)
In winter, do not operate the unit in bypass mode when heating.
(This may cause dew condensation water to drip and dirty the ceiling surface.)
Do not touch the refrigerant pipes with your bare hands during operation.
