1. Indoor Unit:
For indoor unit installation, the distance between its top and the ceiling shall
not be less than 10 cm -20 cm, and the distance from the ground should be between
2m to 2.6m. Also the wallboard must be smooth and straight, with its supporting force
of not less than 60 kg.
The location for installing the indoor unit shall be far away from heat source,
the space between it and the door or window should exceed 0.6m
2. Outdoor Unit:
The air conditioner outdoor unit should not occupy public sidewalks, the
distance between the mounting bracket installed along the road (on condition 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.
3. 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 .
The height difference between wall mounted indoor unit and the outdoor unit
is generally not more than 5 meters.
The connection pipe can't exceed 5 meters, and the longest is 10 meters. ⑵ when
the length exceeds 5 meters, 15g fluoride is required to be added for each exceeding
1m.
