2.2 Installation of the outdoor unit
2.2.1 Installation precautions
" The outdoor unit must only be installed
outside. If a shelter is required, it must have
broad openings on all 4 sides and installation
clearances must be observed (gure 15).
• Choose the location of the appliance after discussion
with the client.
• We recommend choosing a site that is sunny but
sheltered from strong cold prevailing winds.
• The unit must be easily accessible for future installation
and maintenance work (gure 15).
• Ensure that connections to the hydraulic unit can be
made easily.
• The outdoor unit is able to withstand bad weather but
avoid installing it in a position where it is likely to be
exposed to signicant dirt or owing water (under a
defective gutter for example).
• Water may ow out of the outdoor unit when it is
operating. Do not install the unit on a paved terrace;
choose a well-drained location (e.g. gravel or sand).
If installation is carried out in an area where the
temperature stays below 0°C for long periods, check
that the presence of ice does not present any danger.
A drainage pipe can also be connected to the outdoor
unit (see gure 16).
• Nothing should obstruct the air circulation through the
evaporator and out from the fan (gure 15).
• Keep the outdoor unit away from heat sources and
ammable products.
• Make sure that the unit does not disturb the
surrounding area or inhabitants (noise level, draught,
low temperature of the ejected air freezing the plants
in its path).
