With the optional condensates
pan in the outdoor circuit, the
units have 2 special grips
(in the outdoor unit), which
project 98 mm on the crossbar,
whereas they preserve the
original grips in the indoor unit.
Cloth slings with rings
6 - TRANSPORT AND HANDLING
These machines must be unloaded and positioned by a specialist
handling company using the appropriate, standardised tools.
Before handling, check that the path leading to the installation
location is accessible and free from obstacles.
The unit must be handled with care to avoid transport damage.
Thus we recommend:
- Do not dispose of the pallet or the packaging materials until
the unit is in its fi nal location.
- For transport in a container, one must be selected that has
an easy load and unload to the installation location.
Optionally, the unit may have skids that allow the units to
be slid over the fl oor so that the container would be easily
removable (except with assemblies MC1, MWC1 and MRC1).
These skids make transport pallets unnecessary.
Skid
The unit can be discharged using a crane with a rocker arm
and cloth slings by using a forklift truck if it is done on the side
of the transport box. If the unit has transport skids at the same
height of the transport box, the unit can be discharged simply
by pulling on the skids at the points set out for them.
When using any of the three above methods, it is always
mandatory to grasp the unit by the points intended for that
purpose, as described in this chapter.
Any handling of the unit by other means or by gripping points
diff erent from those described here may be dangerous for both
the unit and the personnel who are carrying out the discharging
or transport work.
Always check the weight of the unit and verify that the
discharging method used is approved for handling
that weight.
● Discharge via forklift truck:
The unit is designed to be transported safely by using a forklift
truck. The forks of the forklift truck must come in on the side of
the unit, ensuring that the centre of gravity of the unit remains
within the forks, because a misbalance in the transport may
cause the unit to turn over and fall from the forklift truck.
Note: please see the weight and the gravity centre coordinates
of each model stated in the following page.
The recommended length for the forks will be bigger than the
unit width, so that the entire weight-bearing structure of the
unit can be supported on the forklift truck. This also prevents
the possible introduction of the truck’s fork into functional parts
of the unit that may cause damage to the unit.
The standards and recommendations of the forklift truck
must also be respected with regards to the maximum load,
inclination of the fork carriage, elevation of the load for
transport, and, in particular, the maximum speed.
● Discharging to the same plane using skids (optional):
This method will be used only when it is possible to place the
transport box (trailer, maritime container, etc.) at the same
height as the discharging platform (for example, a dock).
To do so, each skid will be gripped by the points indicated in
the previus image, so that it can be pulled from the unit to be
extracted from the box.
Once the unit is discharged, it must be freed from the grips
and the skids so that the inserts available for the silent-blocks
can be accessed. Both are fi xed to the crossbar using M10
screws (hex. key 17).
Gripping point
Unit with condensates pan in the outdoor circuit:
After the placing of the unit, it is recommended to remove the
grips as they can be a hindrance for maintenance. Put the
grips back in case of unit transport. The grips are fi xed to the
crossbar using M10 screws (hex. key 17).
● Discharge via crane:
A rocker arm, as well as approved cloth slings, both suitable for
the dimensions and weight of the unit, must be used in order
to carry out the work safely and without causing damage to the
units or to workers.
These slings will be hooked to the two grips located on each
crossbar. Make sure that the unit is protected from contact
with the hooks to prevent damage to the housing.
Do not raise any of the units by points outside of
those specifi ed here. In particular, do not raise them
by the traction points of the skids.
The unit must be lifted and fixed with care and without
inclination (maximum inclination 15º), since it could harm its
operation.
The centre of gravity is not necessarily in the middle of the unit
and the forces applied to the slings are not always identical.
Please consult the weight and the centre of gravity of each
model stated in the following page.
