D-EIMAC00801-17EN-AR - 10/44
10-12 fans version
(The drawing shows only the 8 fans version. For the 10-12 fans version the lifting mode is the same)
For installation on the ground, a strong concrete base, at least
250 mm thickness and wider than the unit must be provided.
This base must be able to support the weight of the unit. The
unit must be installed above antivibrating mounts (AVM),
rubber or spring types. The unit frame must be perfectly
levelled above the AVM.
Installation such as in the figure above must always be
avoided. In case the AVM’s are not adjustable (spring type are
normally not adjustable) the flatness of the unit frame must be
guaranteed by using metal plate spacers.
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 and
10 mm for units over 7 m.
If the unit is installed in places that are easily accessible to
people and animals, it is advisable to install protection grids for
the condenser and compressor sections.
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.
The water in the system must be particularly clean and all
traces of oil and rust must be removed. A mechanical
water filter must be installed on the unit
’s inlet piping.
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. Figure 4 shows the minimum space
required.
Vertical air discharge must not be obstructed.
If the unit is surrounded by walls or obstacles of the same
height as the unit, this must be installed at a distance no lower
than (see Figure 4C or 4D). If these obstacles are higher, the
unit must be installed at a distance no lower (see Figure 4E or
4F).
Should the unit be installed without observing the
recommended minimum distances from walls and/or vertical
