Designated use

The DHW tank can be operated in a solar thermal system with a boiler as
a back-up, or for high output only with a boiler. (Operation of the two
heat exchangers in series or parallel.) The tank is designed for heating
and storing drinking water. Please observe national, regional, and local
codes, regulations, guidelines and standards for drinking water. When
operated as part of a solar system, the solar thermal system must be
filled with solar antifreeze to prevent frost damage.
The tank can be used only in closed loop systems and is not suitable for
drain-back solar thermal systems. Any other purpose is considered
improper use. Any resulting damage is excluded from the
manufacturer's warranty.
