2) Lower edge of storage cylinder to lower edge of collector (Figure 28 page31).
3) In order to achieve higher frost protection, the glycol content needs to be increased to over 33 %. However, this results in increased
pressure drop and hence a reduced maximum installation height and length of solar circuit. Please also observe the technical
information of the solar liquid. If required feel free to contact our technical support.
