Windbreaker

The  outdoor  unit  is  designed  for  outdoor  installation  only,  and  for  the  following
ambient temperatures:

Cooling mode

10~43°C

Heating mode

–28~35°C

Special requirements for R32

The  outdoor  unit  contains  an  internal  refrigerant  circuit  (R32),  but  you  do  NOT
have to do any refrigerant field piping, or refrigerant charging.

Mind the following requirements and precautions:

WARNING

Do NOT pierce or burn.

Do  NOT  use  means  to  accelerate  the  defrosting  process  or  to  clean  the
equipment, other than those recommended by the manufacturer.

Be aware that R32 refrigerant does NOT contain an odour.

WARNING

The  appliance  shall  be  stored  so  as  to  prevent  mechanical  damage  and  in  a  well-
ventilated  room  without  continuously  operating  ignition  sources  (example:  open
flames, an operating gas appliance or an operating electric heater).

WARNING

Make  sure  installation,  servicing,  maintenance  and  repair  comply  with  instructions
from  Daikin  and  with  applicable  legislation  and  are  executed  ONLY  by  authorised
