A clear space of at least 600mm shall be made in front of the heat pump. Plants or foliage in front of the
heat pump may provide a good source of visible protection and absorb some of the high frequencies
generated by the inverter but at this distance, should not be allowed to grow above half the height of
the unit. The air expressed from the front of the heat pump shall often be at sub zero temperatures
which may damage such flora .
Ideally 500mm should be made available either side of the heat pump to facilitate efficient air flow and
allow maintenance access. In exceptional conditions, this space may be reduced to the absolute
minimums expressed in the service manual, although performance may be affected and maintenance
access may be compromised.
The heat pump should be sited away from sources of falling leaves, build up of snow and strong winds.
Details of space limitations for more complex spaces are shown on page 13 of the Service manual.
Mounting
Ideally the heat pump shall be mounted on a concrete base of dimensions greater than 440mm x
1250mm. The base shall be separated from any dwelling and shall provide drainage for any condensate
run off. A typical base is shown below.
Drainage must be made available from the slab for rainwater runoff and heat pump condensate.
Condensate is fresh water without contaminants but may be very cold and subject to freezing during
cold weather. Such run off must be directed away from walk ways and shall ideally be to gravel
surrounding the concrete base to aid natural drainage.
