CAUTION
Be careful that matters, such as wastes of sand
s,water,
, etc. shall not enter the pipe.
The standard pipe length is C m. If it is over D m, the function of the unit will be affected. If the pipe
has
to be lengthened, the refrigerant should be charged,
according to E g/m. But the charge of refrigerant
