separator must be fitted during installation. The contact opening
must be at least 3 mm.

if the connecting cable is fed into the heater via one of the bottom
holes 14a!

Installation note

by the respective utility operator or by a qualified specialist company,
who can also assist you when you are requesting the approval of
the utility company for installation of the appliance.
