2 Safety notes
2.1 Correct use
Safety in operation is only guaranteed if the fitting is
used correctly.
The ZB isolating fitting “Multiflex F” is used in one or
two pipe central heating and cooling systems with
closed circuits for the connection of radiators with
integrated distributors with a distance of 50 mm between
the pipe centres.
Any use of the isolating fitting outside the above
application will be considered as non-compliant and
misuse. Claims of any kind against the manufacturer
and/or his authorised representatives, regarding
damages caused by incorrect use, cannot be accepted.
The observance of the installation and operating
instructions is part of the compliance terms.
2.2 Possible dangers at the installation location
and during transport
The case of an external fire was not taken into
consideration when constructing the isolating fitting.
