•
Ensure that all pipes are elastically suspended, with mountings as illustrated or similar. This is so that the rubber
(or similar material) compresses 1 to 2 mm under vibration. It is not recommended to suspend the pipes from
too many points, as the force at each mounting is then not sufficient.
Figure 5.
Elastic pipe suspension.
•
If the heat pump is located indoors and the ceiling in the area is unsuitable to suspend the aforementioned pipe
mountings, set up (or construct) special stands on the floor from which the pipes can be suspended.
•
Ensure that pipe lines do not lie against walls that they run along and that foam insulation is wrapped around
the entire pipe, not just on top of it.
•
Pipes inside the heat pump must not be against each other (if they are, clamp and secure suitable rubber, pulling
the pipes apart by hand only helps temporarily).
•
If the heat pump is on an unstable surface, position rubber feet designed for its weight underneath.
•
If necessary, use rubber straps to secure flexible hoses in position, so that they do not lie against each other or
create vibration bridges.
•
Ensure that electrical wiring is not put under strain, if it is it creates vibration bridges.
•
If possible, install the heat pump in a location that is sound insulated from areas that are frequented by residents.
Soundproofing measures to carry out afterwards:
•
Go through the aforementioned points and improve if possible.
•
Hood for compressor (most effective for high frequencies).
•
Improve the acoustic environment of the heat pump by installing acoustic panels on the walls and ceiling.
•
In some instances, it is recommended that the heat pump is moved to another area.

Electrical connection
Caution! Electrical installation may only be carried out by an authorized electrician and must follow
applicable local and national regulations.
Caution! The electrical installation must be carried out using permanently routed cables. It must be possible
to isolate the power supply using an all-pole circuit breaker with a minimum contact gap of 3 mm.
For information regarding maximum load for externally connected devices, see electrical installation instructions.
