They describe separate spaces: theoretical condensate volume of the relevant models is 150 / 250 mL, while theoretical coolant volume is 1000 / 2000 mL.
Why
Condensate collection and surrounding coolant spaces are not interchangeable. More coolant volume does not mean equal condensate capacity.[1]
These are theoretical volumes, not unrestricted operating fill quantities. Match each value to its model.
What to confirm
Confirm model and connections, then both spaces separately. Follow instructions for filling and operation; do not turn theoretical volume into an on-site capacity guarantee.
