Unit Placement

In addition to clearances, the following items should be 

considered:

WARNING

!

Use  the  provided  and  specified  components  when 

installing equipment. Failure to do so may result in 

unit falling, water leaking or electrical shocks, caus­

ing personal injury or equipment or property dam age.

Check  stability  of  wall,  floor,  or  ceiling  and  unit 

support. If sup port is not capable of carrying weight 

of the unit, unit may fall causing personal injury or 

equipment 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.

AVOID

Do not install the unit in the following locations:
•  Areas exposed to petrochemicals or petrochemical 

products

•  Areas exposed to salt or other corrosive materials or 

caustic gasses

•  Areas exposed to extreme voltage variations (such as 

factories

•  Tightly enclosed areas that may impede service of the 

unit

•  Areas exposed to fossil fuels (such as oil or gas in 

kitchens)

•  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.  

• 

Ensure  the  structural  wall  or  floor  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.

Installation

1.  Locate a suitable position within the space where 

maintenance access and supply air will not be restricted 

or affected by obstacles. The minimum clearances are 

given on Page 5.

CAUTION

!

Do not place items which may be damaged by water 

under or around the indoor unit.

The unit should be installed at least 8 feet above the 

floor  (if  possible)  to  ensure  maximum  performance 

and comfort, when installed in the horizontal position   

only.

• 

Allow sufficient space around unit for proper operation 

and maintenance (filter must able to be removed from 

the front/bottom of the unit).

•  Install 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

•  Be sure to instruct customers how to properly 

operate  the  unit  (especially  maintenance  of  air  filter, 

and operation procedure) by having them carry out 

operations themselves while looking at the manual 

provided with the controller.

1.  Remove the unit casing (VSC units only) by 

removing the six screws shown in Figure 1. 

After installation is complete, re-install the unit casing 

by replacing the cover plate and side plate screws. It is 

not necessary to replace the base screws.

2.  The unit can be secured to a wall or mounted 

on optional support feet V8VSA001-3P (19X68).
