If more than one unit is installed, the minimum distance between the finned coils should be at least 2 m.
(**)
Minimum distance for the removal of the pump unit and the relative tank. If the accessory is not present, the distance can be reduced.
(***)
Minimum distance for the electrical panel opening.
N.B.
When installing the unit, bear the following in mind:
• non-soundproofed reflecting walls near the unit may increase the total sound pressure level reading near the appliance by as much as 3 dB(A) for every
surface;
• install suitable anti-vibration mountings under the unit to avoid transmitting vibrations to the building structure;
• on top of buildings, solid floor frames can be provided which support the unit and transmit its weight to the support elements of the building;
• make all water connections using elastic joints; pipes must be firmly supported by solid structures. If the pipes are routed through walls or panels, insulate
with elastic sleeves.
If, after installation and start-up of the unit, structural vibrations are observed in the building which provoke such strong resonance that noise is generated in
other parts of the building, refer to a qualified acoustic technician for a complete analysis of the problem.
