Minimum space requirements

It is fundamental to respect minimum distances on all units in order to ensure optimum ventilation to the condenser.
Limited installation space could reduce the normal air flow, thus significantly reducing the machine's performance and
considerably increasing consumption of electrical energy.
When deciding where to position the machine and to ensure a proper air flow, the following factors must be taken into
consideration: avoid any warm air recirculation and 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. Thanks to the geometry of their air-cooled condensers, the units are less affected by poor air
circulation conditions.
Also, the software has particularly the ability to compute the machine's operating conditions to optimise the load under
abnormal operating circumstances.
Every side of the machine must be accessible for post-installation maintenance operations. Figure 4 shows the minimum
space required.
Vertical air discharge must not be obstructed as this would significantly reduce capacity and efficiency.
If the machine is surrounded by walls or obstacles of the same height as the machine, it must be installed at a distance
of at least 2500 mm. If these obstacles are higher, the machine must be installed at a distance of at least 3000 mm.
Should the machine 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 machine to adapt itself to new operating conditions and deliver the
maximum capacity available under any given circumstances, even if the lateral distance is lower than recommended.
When two or more machines are positioned side by side, a distance of at least 3600 mm between the respective
condenser banks is recommended.
