Noise and vibrations
6.4.1
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. Vibration dampers are available to pur-
chase as accessories.
•
Connection of the heat transfer fluid to the heat pump must be made using a flexible hose to prevent trans-
mission of vibration to building construction and the pipe system, see Flexible hoses, Page 30.
•
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.
6.4.2
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
