Step 2.8 Installing and connecting the
assembly pipes to the refrigerant pipes
(assembly pipe)
Connect indoor and outdoor units with field-supplied
copper pipes by means of flare connections. Use
insulated seamless refrigeration grade pipe only,
(Cu DHP type according to ISO1337), degreased and
deoxidized, suitable for operating pressures of at least
4200 kPa and for burst pressure of at least 20700 kPa.
Under no circumstances must sanitary type copper pipe
be used.
There are 2 refrigerant pipes of different diameters:
• The smaller one is for the liquid refrigerant
• The larger one is for the gas refrigerant
A short liquid refrigerant pipe and a short gas refrigerant
pipe are already fitted to the air conditioner. The
connection procedure for the refrigerant pipes varies
according to the exit position of each pipe when facing
the wall:
