Minimum space requirements

It is fundamental to respect minimum distances on all units in order to ensure optimum ventilation to the condenser coils.
When deciding where to position the unit and to ensure a proper air flow, the following factors must be taken into
consideration:

avoid any warm air recirculation;

avoid insufficient air supply to the air-cooled condenser.
Both these conditions can cause an increase of condensing pressure, which leads to a reduction in energy efficiency and
refrigerating capacity.
Any side of the unit must be accessible for post-installation maintenance operations and vertical air discharge must not be
obstructed. Figure below shows the minimum space required.
Vertical air discharge must not be obstructed.
In case of two chillers installed in free field, minimum recommended distance between them is 3600 mm; in case of two
chillers in a row, minimum distance is 1500 mm. The pictures below show examples of recommended installations.
Should the unit be installed without observing the recommended minimum distances from walls and/or vertical obstacles,
there could be a combination of warm air recirculation and/or insufficient supply to the air-cooled condenser which could
cause a reduction of capacity and efficiency.
In any case, the microprocessor will allow the unit to adapt itself to new operating conditions and deliver the maximum
available capacity under any given circumstances, even if the lateral distance is lower than recommended, unless the
operating conditions should affect personnel safety or unit reliability.
