(****) 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.
