Please note
Contamination (e.g. metal swarf) or moisture in
the copper pipes of the refrigerant lines will
cause the appliance to malfunction.
Hold the pipe openings downwards or tempora-
rily plug them.
Note
The refrigerant lines of the internal unit are filled with
nitrogen; positive pressure 1 to 2 bar (0.1 to 0.2 MPa).
1.
Undo the nuts from refrigerant connections
C
and
D
.
Type AWB/AWB-AC 201.B04:
Replace nuts with union nuts supplied:
■
⁷
⁄
₁₆
UNF for liquid line
■
¾
UNF for hot gas line
Connect supplied reducer with copper sealing ring.
Type AWB/AWB-AC 201.B05 to B13, 201.C10 to
C16:
Push the nuts onto the relevant refrigerant lines
from the external unit.
2.
Flare the pipe ends of the refrigerant lines.
Note
If solder fittings are used, solder the fittings using a
shielding gas.
3.
Fit refrigerant lines and insulate them to provide
protection from heat and vapour diffusion.
Tighten the nuts with the following torque:
