5. Installation details
5.1 Installation place
5.1.1 Indoor Unit
a.Ensure the spaces indicated by arrows from the wall, ceiling, fence or other obstacles.
b.There should not be any heat source or steam near the unit.
c.There should not be any obstacles blocking the air circulation.
d.A place where air circulation in the room is good.
e.A place where drainage can be easily done.
f.Do not install the unit near the door way.
g.There should not be any direct sunlight. Otherwise, the sun will fade the plastic
cabinet and affect its appearance. If unavoidable, sunlight prevention should be taken into
consideration.
5.1.1.1 Please stand the unit in hard and flat ground;
Please reserve space for installation and maintenance.
5.1.1.2 Please check the elevation difference between the indoor unit and the outdoor
unit, the length of the refrigerant pipe, and the curved places (bend) of the pipe are no
more than the following numbers:
Elevation difference: no more than 15 M (if the elevation difference between indoor
and outdoor unit is more than 15 meters, it is recommended
that the indoor unit be located higher than the outdoor unit.)
Pipe length: no more than 30M
Bends: no more than 3 places.
5.1.2 Outdoor Unit
The outdoor unit should be put in a position that guarantees the minimum space for
sufficient air circulation and to allow maintenance work and the connections of electrical
and refrigerant circuit lines. It may be installed on a floor or flat roof or wall-mounted,
provided its weight isproperly supported and there is no transmission of vibration to the
adjacent rooms.
5.1.2.1 Before installing the outdoor unit, you should:
a).If an awning is built over the unit to prevent direct sunlight or rain, be careful that heat
radiation from the condenser is not obstructed.

7
b).Select a place that is easy to connect indoor unit's pipe and electric wires.
c).Avoid a place where combustible gas may leak or stay.
d).Keep it in mind that water may drain out of the outdoor unit while in "Heat" mode.
e).Ensure the space around the back and sides and the front of the unit.
f).Take the air conditioner weight into account and select a place where noise and
vibration are minimum.
5.1.2.2 If the outdoor unit is to be installed on a roof or where no constructions are around,
you should avoid hard wind blows directly to the air outlet, because it may
cause trouble for air-flow shortage.
5.1.2.3 Reserve enough space for installation, maintenance and unit-functioning.
Remove as many obstacles as possible nearby.
Caution:
Installation in the following places may cause trouble. If it is unavoidable to use in such
places,please consult with the dealer.
(1) A place full of machine oil.
(2) A saline place such as coast.
(3) Hot-spring resort.
(4) A place full of sulfide gas.
(5) A place where there are high frequency machines such as wireless installation,
welding machine, medical facility.
(6) A place of special environmental conditions.
