Caution
Avoid narrow radii during bending. Use a suitable round object as a
bending aid. If the radius is too narrow, the refrigerant line will be kinked
and the air conditioner would not be ready for operation.
Caution
Before fastening the connection couplings, make sure that the sealing
and thread faces are absolutely clean. Any contamination will result in a
malfunction of the air conditioner.

Caution
The tube couplings are single couplings! The couplings must not be
removed once they are connected.
