After the placing of the unit, it is recommended to remove the grips
as well as the skids, if applicable, as they can be a hindrance for
maintenance. Put the grips back in case of unit transport. Each grip
is
fi
xed to the crossbar using two M10 screws (hex. key 17).
Unit with condensates pan from the outdoor circuit:
With the outdoor circuit
condensates pan option, the
units include grips as the lifting
system. Check that the grips
are perfectly screwed in before
attaching the slings.
Do not raise any of the units by points outside of those
speci
fi
ed here. In particular, do not raise them by the
traction points of the skids.
The unit must be lifted and
fi
xed with care and without inclination
(maximum inclination 15º), since it could harm its operation.
Note: please see the weight and the gravity centre coordinates of
each model stated in the following page.

RANSPORT AND HANDLING
Transport
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. These skids make transport
pallets unnecessary.
Discharging of the unit
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 different
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 set 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.
Make sure that the unit is
protected from contact with the
hooks to prevent damage to
the housing.
- 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 mounting holes located
on each crossbar.
- 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).
Once the unit is discharged, it must be freed from the skids so that
the inserts available for the silent-blocks can be accessed. Each
skid is
fi
xed to the crossbar using four M10 screws (hex. key 17).
To do so, each skid
will be gripped by the
points indicated in the
image so that it can be
pulled from the unit to be
extracted from the box.
