Procedure for Selecting the Location
Choose a place solid enough to bear the weight and vibration of the unit,where the operation noise will not be amplified.
Choose a location where the hot air discharged from the unit or the operation noise,will not cause a nuisance to the neighbors
of the user.
Avoid places near a bedroom and the like,so that the operation noise will cause no trouble.
There must be sufficient space for carrying the unit into and out of the site.
There must be sufficient space for air passage and no obstructions aroud the air inlet and air outlet.
The site must be free from the possibility of flammable gas leakage in a nearby place.
Locate the unit so that the noise and discharged hot air will not annoy the neighbors.
Install units,power cords and inter-unit cables at least 10ft away from televison and radio sets,This is prevent interference to
images and sounds.(Noise may be heard even if they are more than 10ft away depending on radio wave conditions.)
In coastal areas or other places with salty atmosphere of sulfate gas,corrosion may shorten the life of the air condition.
Since drain flows out of the outdoor unit,do not place under the unit anything which must be kept away from moisture.
