Before unit commissioning, the flatness must be verified by using a
laser levelling device or other similar devices. The flatness shall not be
over 5 mm for units within 7 m length.
To ensure best 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;
■
Make sure to provide a strong and solid foundation to reduce
noise and vibrations;
■
Avoid installation in particularly dusty environments, in order to
reduce soiling of condensers coils;
4.4. Minimum space requirements
It is fundamental to respect minimum distances on all units 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 aircooled 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 postinstallation
maintenance operations and vertical air discharge must not be
obstructed. Figure below shows the minimum space required.

If the unit is installed in a free field, the distances indicated are:
A/B/C/D ≥ 500 mm
In the presence of obstacles or walls, the following minimum
distances are recommended:
h2 > 0 → A ≥ A + h2
2
h1 > 0 → C ≥ C + h1

If two units are installed in a free field side by side along their longer
sides, A and C, the minimum recommended distance between them
is 1000 mm; if two units are installed side by side along their shorter
sides, sides B and D, the minimum distance between them should be
500 mm. 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 aircooled 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.
