Adoption of New Refrigerant
This Air Conditioner is a new type which adopts a new refrigerant HFC (R410A) instead of the conventional
refrigerant R22 in order to prevent destruction of the ozone layer.
WARNING
Cleaning of the air filter and other parts of the air filter involves dangerous work in high places, so be sure to
have a service person do it. Do not attempt it yourself.
The cleaning diagram for the air filter is there for the service person, and not for the customer.
