There is enough room for installation and maintenance.
The air outlet and the air inlet are not impeded, and can not be 
reached by strong wind.
It must be a dry and well ventilating place.
The support is flat and horizontal and can stand the weight of 
the outdoor unit. And will no additional noise or vibration.
Your neighborhood will not feel uncomfortable with the noise or 
expelled air.
It is easy to install the connecting pipes or cables.
Determine the air outlet direction where the discharged air is not 
blocked.
There is no danger of fire due to leakage of inflammable gas.
The piping length between the outdoor unit and the indoor unit 
may not exceed the allowable piping length.
In the case that the installation place is exposed to strong wind 
such  as  a  seaside,  make  sure  the  fan  operating  properly  by 
putting  the  unit  lengthwise  along  the  wall  or  using  a  dust 
shield.(Refer to Fig 4.1)
If possible, do not install the unit where it is exposed to direct 
sunlight. 
If necessary, install a blind that does  not interfere with the air 
flow.
Select  the  position  where  it  will not be  subject  to snow  drifts, 
accumulation of leaves or other seasonal debris. If unavoidable, 
please cover it with a shelter.
Locate the outdoor unit as close to the indoor unit as possible.
If possible, please remove the obstacles nearby to prevent the 
performance from being impeded by too little of air circulation.
The minimum distance between the outdoor unit and obstacles 
described in the installation chart does not mean that the same 
is applicable to the  situation of an airtight room. Leave open two 
of the three directions (M,N,P)
