• For medium temperatures above 50 °C (122 °F) some parts of the housing can
heat up to over 65 °C (149 °F)� Moreover, during installation or in case of a fault
(e�g� housing damage) media under high pressure or hot media can leak from
the system� To avoid personal injury, take the following measures:
► Install the unit according to the applicable rules and regulations�
