Benchmark

Vaillant is a licensed member of the Benchmark Scheme.
Benchmark places responsibilities on both manufacturers
and installers. The purpose is to ensure that customers are
provided with the correct equipment for their needs, that it is
installed, commissioned and serviced in accordance with the
manufacturer's instructions by a competent person approved
at the time by the Health and Safety Executive and that it
meets the requirements of the appropriate Building Regu-
lations. The Benchmark Checklist can be used to demon-
strate compliance with Building Regulations and should be
provided to the customer for future reference.
Installers are required to carry out installation, commission-
ing and servicing work in accordance with the Benchmark
Code of Practice which is available from the Heating and
Hotwater Industry Council who manage and promote the
Scheme.
Benchmark is managed and promoted by the Heating and
Hotwater Industry Council.

Selecting the installation site

▶
Select a dry room that is frost-proof throughout and in
which the maximum installation height is not exceeded
and the ambient temperature is neither above nor below
the permitted range.
– Permissible ambient temperature: 7 ... 25 ℃
–
Permissible relative air humidity: 40 ... 75 %
▶
Ensure that the installation room has the required min-
imum volume.

▶
Ensure that the required minimum clearances can be
maintained.
▶
When selecting the installation site, you must take into
consideration that when the heat pump is in operation, it
will transfer vibrations to the floor and the nearby walls.
▶
Ensure that the floor is level and has sufficient load-bear-
ing capacity to bear the weight of the heat pump and a
domestic hot water cylinder.
▶
Ensure that cables can be easily routed (for brine, hot
water and heating).
