1. R EFRIGERANTS R32
1.1. I NTRODUCTION
The refrigerants used for air conditioners are encironmentally friendly hydrocarbons R32. The two kinds of refrigerants are
combustible and odorless. Moreo er, the can burn and explode under certain condition. Howe er, there will be no risk of
burning and explosion if you comply with hte following table to install your air conditioner in a room with an appropriate area
and use it correctly.
Compared with ordinary refigerants, Refrigerants R32 are en ironmentally friendly and do not destroy the ozone sphere and
that their alyes of greenhouse oeffect are also ery low.

damaged, contact the ser ice department to replace
it. Otherwise, there is a risk of electric shock or fire.
• Do not touch de ices with wet or damp hands.
• Do not obstruct the air inlet and outlet of the air
conditioner and outdoor unit. Blocking them will
reduce the efficiency of the de ices as well as failures
and damage.
