Risk of burns!
The valves, fittings and the pump may heat up to more than 212 °F (100 °C) during
operation.

Personal injury and material damage!

neutral pH.

The zone module may not be used in sanitary water applications.

Flush the heating circuit before installation to remove scale residues.
Material damage due to mineral oils!
Mineral oil products permanently damage the EDPM sealing elements, resulting in a loss
of their sealing characteristics. We cannot be held liable for damage caused by seals
thus damaged, nor will we offer a replacement under warranty.
¾
It is imperative to prevent the EPDM sealing elements from making contact with
substances containing mineral oils.
¾
Use silicone- or polyalkylene-based lubricants free of mineral oil, such as Unisilikon
L250L and Syntheso Glep 1 from the company Klüber or a silicone spray.
