Nope, you're wrong. The heat pump connects directly to the Supermanifold. And the LCC, liquid cooled condenser, and chiller, also both attach to the Supermanifold. (The temperature/pressure sensors that they replaced last year are also attached to the Supermanifold.)
You can see the heat pump refrigerant lines connected to the Supermanifold in the Munro tear down video here:
There is also the part that calls out the line from the Supermanifold to the compressor:

I think the LCC and chiller are both part of the Supermanifold assembly, so since they get contaminated they have to replace the whole assembly.
