that the mounting bracket does not affect the public access, it can be installed
horizontally) and the ground must exceed 2.5m. Also we shall remember that:
a. the air flow must run freely. b. we should protect famous ancient buildings
during installation. c. the installation does not affect the traffic.
The distance between air outlet of outdoor unit and the opposite object
should be more than 1 meter, otherwise the machine would stop running
because of overload by heat yield failure.
If the outdoor unit was opposite the resident's door or window, you should
install the machine as far as possible away from the adjacent doors windows
and plants, and the distance shall not be less than the following values: for the
rated cooling capacity not more than 4.5KW, the distance should be 3m.; for the
rated cooling capacity more than 4.5KW, the distance should be 4m.
It should remember to avoid installing at places where the natural
environment is harsh, such as heavy fumes and wind, direct sunlight or
high-temperature and heat, together with the place where children easily reach.
4. The Unit:
When installing the air conditioner, the outdoor unit should be below the
indoor unit so as to facilitate circle of refrigerant and refrigeration oil .(1)The
height difference between wall mounted indoor unit and the outdoor unit is
generally not more than 7 meters. (2)The connection pipe can't exceed 5
meters, and the longest is 15 meters. When the length exceeds 5 meters, 20g
