SSESSMENT
i) Window type air-conditioning units
The Client shall provide relevant drawings and specifications
demonstrating that the air-conditioning units installed comply with the
installation requirements given in Tables 8.4 and 8.5 in Section 8.4.
ii) Split-type air-conditioning units

unit.
Compliance with the requirements shall be demonstrated for each type
of domestic unit in a block, or each type of space or room in other types
of premises, unless the Client can demonstrate either that circumstances
mitigate against compliance in not more than 10% of installations, or that
non-compliance will not affect the performance of air-conditioning units in
respect of room cooling, or heat rejection.
The Client shall confirm that the installation conforms with any four of the
following items that are relevant to the type of air-conditioning units used:
to reduce penetration of noise units shall be located on walls which
do not face major noise sources (road traffic, major pedestrian
walkways, playgrounds, etc);
to reduce intake of polluted air units shall be located in walls such
that air is not drawn in from pollution sources such as roads,
commercial activities, etc;
for improved acoustics properties and better circulation, the internal
discharge shall be close to the centre of the wall in which it is
located;
for the purpose of reducing noise from rain, and to reduce the
potential for water dripping on to lower units, slabs shall be provided
as support and as cover;
to encourage proper maintenance, the installation of units shall be
such as to allow for safe and convenient removal;
