around 50-60 degree C; it may be having 

an effect on environments especially tree, 

plant, or shrub etc. 

4.  Make sure that outlet air is moved out

the fan is rotating at high speed, cleaning 

during operation may cause injury) 

9.  Do not place a vessel containing water or 

any object on the condensing unit and do 

not stand or sit on the condensing unit. 

10.  The condensing unit should not be 

installed where normal operation sounds 

may be objectionable. On either rooftop 

or ground level installations. Rubber 

padding can be applied between the 

base rails and their supports to lesson 

any transmission of vibration. 

11.  The fan of condensing unit is the 

propeller type. It is not suitable for use 

with duct work. 

12.  Make sure that the surrounding 

atmosphere does not contain noxious or 

dangerous substances such as oil vapors
