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:
