Tomensure the best possible performance on the installation site, the following precautions and instructions must be
followed:
Avoid air flow recirculation
Make sure that there are no obstacles to hamper air flow.
Air must circulate freely to ensure proper intake and expulsion.
Ensure strong and solid flooring to reduce noise and vibrations as much as possible.
Avoid installation in particularly dusty environments, in order to reduce soiling of condenser batteries.
The water in the system must be particularly clean and all traces of oil and rust must be removed. Installation of a
mechanical water filter is required for the machin
e’s input piping.
Minimum space requirements
It is fundamental to respect minimum distances on all units, in order to ensure optimum ventilation for the condenser
batteries. Limited installation space could reduce the normal air flow, thus significantly r
educing 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 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 bad air
circulation situations.
Also, the
software has a particular ability for calculationg the machine’s operating conditions and for optimising the load
under abnormal operating conditions.
Every side of the machine must be accessible for post-installation maintenance operations. Figure 3 shows the minimum
space required.
Vertical air expulsion must not be obstructed as this would significantly reduce capacity and efficiency.
If the machine is positioned in such a way as to be surrounded by walls or with 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 adjust to new conditions by producing the maximum avai lable
capacity, 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 condenser batteries is
recommended.
