Indoor Unit Placement

AVOID

Do not install the unit in the following locations:
•  Areas exposed to salt or other corrosive materials or 

caustic gases

•  Areas exposed to extreme voltage variations (such as 

factories)

•  Tightly enclosed areas that may impede service of the 

unit.

•  Areas exposed to strong electromagnetic forces
•  Areas exposed to acids or alkaline detergents (laundry
•  rooms)

DO

•  Locate the unit so that it is not exposed to direct 

sunlight.

•  Locate the indoor unit so that the room can be uniformly 

cooled. Install unit as high as possible on the wall (8 

feet above floor, if possible) for best performance.

•  Select a wall location that can support the weight of 

the unit.

•  Select a location where condensate line will have the 

shortest run to a suitable drain per local codes.

•  Allow sufficient space around unit for proper operation 

and maintenance (filter must able to be removed from 

the top-front of the unit).

•  Install the indoor unit a minimum of 3 feet away from 

any  antenna,  power  cord  (line),  radio,  telephone, 

security system, or intercom. Electrical interference 

and radio frequencies from any of these sources may 

affect operation.

 

WARNING

Do  not  install  the  unit  in  an  area  where  flammable 

materials are present due to risk of explosion resulting 

in serious injury or death.
Check suitability of structure to which the unit support 

mechanism will be fixed to. If structure is not capable 

of carrying the weight of the unit, unit may fall causing 

personal injury or equipment damage.
Use  the  provided  and  specified  components  when 

installing equipment. Failure to do so may result in 

unit  falling, water leaking or electrical shocks, causing 

personal injury or equipment or property damage. 
Consider the possibility of earthquakes in your area 

when installing the equipment. If the unit is not correctly 

secured, it may fall, causing personal injury or equipment 

damage.
Safely dispose of packing materials, which include 

nails, wood and other sharp objects, as well as plastic 

wrapping. Children playing with plastic wrap or bags risk 

the danger of suffocation.

 

Do not place items which may be damaged by water 

under or around the unit.
The unit should be installed at least 8 feet above the 

floor (if possible) to ensure maximum performance and 

comfort.
