Heater Tap: the tap in the pics is a flow reducer, its not actually a tap, the system uses this to help the a/c with hot start up with the a/c on, to deliver maximum cold as fast as possible. Many people have deleted this feature and not had issues.

* It is the responsibility of the fitter to clean and check all parts before fitting.
