5.4 Noise information
5.4.1 Installation of the heat pump
To prevent disturbing noise from the heat pump the following recommendations should be observed:
▪
In the event the heat pump is positioned on a vibration sensitive base, vibration dampers should be used. The vibration dampers
must be correctly dimensioned with regard to the heat pump's weight so that static spring depression of at least 2 mm is obtained
in all mounting components.
▪
Connection of the heat transfer fluid to the heat pump must be made using a flexible hose to prevent transmission of vibration to
building construction and the pipe system, see Flexible hoses.
▪
Ensure that pipes at lead-ins are not lying against the walls.
▪
Ensure that the electrical supply cable does not provide a path for vibration because it is overstretched.
5.4.2
Flexible hoses
All pipes should be routed in such a way that vibrations cannot be transmitted from the heat pump through the piping and out into the
building. This also applies to the expansion pipe. We recommend that flexible hoses are used for all pipe connections to avoid the trans-
mission of vibrations. Flexible hoses are available to purchase as accessories. The figures below show how appropriate and inappropriate
installations look using this type of hose.
