2-2-6.1 Noise transmitted by solid materials
To avoid transmitting noise throughout your interior, make sure that hoses and pipes passing through walls are not
in direct contact with any masonry and use vibration-absorbing pipe suppor ts.
2-2-6.2 Location
The predominant problem with outdoor units is disturbance caused to the neighbourhood because of noise.
This can be minimised by following two rules:
- Use natural barriers wherever possible (e.g. mound of earth, opaque wall) to separate the equipment as far as possible from
your neighbours.
- Wherever possible, avoid placing equipment adjacent to walls. Walls can increase noise levels considerably and reflect
noise in various directions. For your own comfort, avoid locating the equipment too close to sensitive areas (such as bed-
room windows).
