If you are using a crane, sling the unit with slings using suitable lifting tubes (not supplied with the unit) inserted in the slots
on the base of the unit.
Fig. 5 Detail of hooking the sling to the lifting tube
It is mandatory to use a lifting beam adjusted to the width of the unit in order to ensure lifting stability. Also, suitable pro-
tective devices must be placed on the upper edges to prevent the slings from coming into contact with the unit. If the unit is
shipped in rigid packaging, this precaution is not necessary.
Fig. 6 Lifting with crane
If anti-vibration mounts are installed under the base of the unit, this must be done with the unit raised by no more than 200
mm from the ground and without putting any parts of the body under it.
Before sliding out the pallet, remove the four screws fixing the top board of the pallet to the unit.
If the screws fixing the pallet to the unit are visible through the slotted holes of the base, use a 10 mm spanner to unscrew
them.
If the screws are not visible through the slotted holes, they are about 60 centimetres from the corners of the pallet.
Use a 13 mm spanner to unscrew them.
