(****) The water content of the system must be between the minimum and
maximum values for the units with hydronic kit and greater than the minimum
value for units without hydronic kit. The minimum value is necessary to provide
optimal comfort.
For units without hydronic kit, add a suitable expansion vessel to the water
content of the system.
