2 Safety precautions and regulations
14
Frost danger
The system is frost-protected as long as the VEN
appliance is connected to the power supply. For this
reason, it is important not to unplug the appliance from
the mains or disconnect it at the main circuit breakers
when there is a danger of frost.
Note!
As the frost-protection feature does not
cover the supply pipes or valve assemblies
connected to the appliance, you are
recommended to drain the system whenever
there is a danger of frost. Before doing so,
ensure that the appliance is unplugged from
the mains power supply in order to prevent
the system overheating and blowing the
safety fuse.
Modifications
Note that the user must not carry out modifications of
any type to the appliance itself or its power or water
supply.
Inspection
Furring can occur with water of certain types and with
certain water temperatures and levels of consumption.
If the water flow-rate drops noticeably, have the power-
supply and water-inlet components examined by an
authorised service installer.
2.2 Use for intended purpose
These appliances are designed exclusively for the
heating of standard-quality water from the drinking-
water supply, and for indoor home use only. Any
operation that does not conform to these conditions in
all resects counts as incorrect use. Neither the
manufacturer nor the supplier can accept any liability
whatsoever in these circumstances. Such operation is
entirely at the user's own risk.
The definition of intended use includes observance of
the installation and operating instructions and
maintenance of the servicing and inspection schedules.
