6.4 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-

•
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 19.
•
Ensure that pipes at lead-ins are not lying against the walls.
6.4.2 Flexible hoses
