4.3 Layout, assembly of heat pump
NOTICE!
The unit is intended for installation in rooms
other than damp rooms.
n
Depending on local conditions, the noise emis-
sion level of the heat pump should be taken
into account, and where necessary acoustic
insulation measures should be adopted.
n
Do not set the unit down under or next to bed-
rooms.
n
Feed through walls and ceilings with structural
sound insulation.
The room in which the unit is to be installed must
meet the following requirements:
n
it must be free of frost
n
The room must not be at risk of explosion from
dust, gases or vapours.
n
If the unit is installed in a boiler room together
with other heaters, make sure that the opera-
tion of the other heaters is not impaired.
n
The minimum volume of the installation room
must be 15 m
3
.
n
The ground must have a sufficient load-bearing
capacity.
When installing the heat pump, observe the fol-
lowing points:
n
Ensure that the wall bracket is installed level.
The heat pump can be aligned precisely by
means of the adjustment screws on the back of
the housing.
n
The heat pump is to be mounted in such a way
that sufficient space is available on all sides for
purposes of installation and maintenance. It is
equally important that there is sufficient space
above the device for installing the safety
assembly, dirt traps etc.
NOTICE!
Frost or temperatures higher than 35 °C must
not occur in the installation room at any time of
the year.
Decoupling from building
In order to minimize vibrations and noise in the
building, heat pumps must be decoupled from the
building to the greatest extent possible. In general,
the installation of heat pumps on light weight ceil-
ings/floors is to be avoided. Good sound insulation
is achieved by means of a concrete foundation
slab with an underlying rubber mat. If a screed
floor is laid, the screed and impact sound insula-
tion should be removed from around the heat
pump (see illustration below).
Conventional “boiler platforms” are not suitable
as soundproofing measures for heat pumps due
to the resonance effect.
