NOTE
Other assemblies should be prepared on spot except air
conditioner main body.
Cover the pipe before connecting to keep rubbish, dust or other
impurities out.
As there is no dust filter on the indoor unit, other places which
are easy to maintaining such as inhalant duct should be
installed with dust filter. (Without dust filter, dust adherent on
the air heat exchanger may cause failure and water-leak.
