Figure 4
– Unit Levelling
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.
