According to installation requirement (selection in chart)
(1) LDH - LDC - ILDH only
(2) Capacity of the installation as a function of the expansion vessel mounted on the unit.
The auxiliary tank is already taken into account.
In the case where the installation capacity is higher,an expansion vessel must be added on the installation cor-
responding to the surplus capacity.
(3) The water temperatures mentioned are the temperatures which can be reached when the unit is stopped.
