Touching pipes – vibrations
Action:
Establish which pipe(s) causes vibrations and try to remove the tension that is causing the vibrations by, for example, ensuring that no
pipes or flexible hoses are too rigid, if that does not help one can install vibration damping rubber compensators on the vibrating
pipe(s)
Incorrectly installed flexible hoses - vibrations
Action:
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. To prevent transmitting vibration it is recommended
that flexible hoses are used for all pipe connections.
To avoid noise caused by pipe mountings, a rubber-coated pipe clamp should be used to prevent the
transmission of vibrations. However, installation should not be too rigid and the pipe clamp must not be too tight
Do not twist the flexible hoses as they are installed. At threaded connections, use a counter hold spanner.
Cut the hose to the correct length to avoid excess bowing-out or stretching at bends
Cut the hose to the correct length to avoid excess bowing-out or stretching and offset the ends so that the hose is installed
completely straight.
Use fixed pipe bends to avoid excess stress on bends next to connections
