Intended use The appliance is only intended to be installed and operated in sealed unven- ted systems that comply with EN 12828 / DIN 1988, or solar thermal systems that comply with EN 12977, with due atten- tion paid to the associated installation, service and operating instructions.
Observe prior to installation For each number of collectors, there is a Of the 4 rafters, the following are used: specific allocated number of rafter Rafters 1 and 4 anchors or mounting brackets (for use on sheet steel roofs). The spacing between rafters and the potential snow loads dictates how many rafters need to be used for fitting the raf- ter hooks.
