(B)OUTDOOR UNIT

As condensing temperature rises,evaporating temperature rises and cooling capactlydrops.In order 

to achieve maximum cooling capacity,the location selected for outdoor unit should fulfill the following 

requirements:

•Install the condensing (outdoor)unit in away such that hot air distributed by the outdoor condensing 

unit cannot be drawn in again (as in the case of short circuit of hot discharge air).Allow sufficient 

space for maintenance around the unit.

•Ensure that there is no obstruction of air flow into or out of the unit.Remove obstacles which block

 air intake or discharge.

•The location must be well ventilated,so that the unit can draw in and distribute plenty of air thus 

lowering the condensing temperature.

•A place capable of bearing the weight of the outdoor unit and isolating noise and vibration.

•A place protected from direct sunlight 

high rise buildings and ambients above 48`C

.Otherwise 

use an awning for protection,if necessary

INSTALLATION CLEARANCE

•Outdoor units must be installed such that there is no short circuit of the hot discharge air or 

obstruction to smooth air flow. 

We recommend the units be installed 0ne meter above ground level 

were practicable.

 

 

 

 

 
 

 

 

 

CAUTION

If the condensing unit is operated in an atmosphere containing 

chemicals near industrial 

                    areas, high 

salt(coastal area)

 or near bore water

,

 

such substances

 shorten the life time 

                    o

f the unit

 due to corrosion
