Transportation, unpacking and handling internal components
During transportation the dispenser must be handled with care. Please follow the
instructions on the packaging at all times.
When lifting with forklift trucks lift on the areas indicated with the arrows in this
diagram (areas are about 50 cm one from the other).
Always use the proper methods to lift and transport the dispenser. Non-compliance
with the instructions for moving the dispenser could cause serious damages to
things and people.
Once you have received the dispenser, carefully inspect the equipment to ensure
that it has not been damaged during transportation. Any damaged equipment must
be sent back to the shipper.
While unpacking, make sure not to damage the painted surfaces.
Do not remove the film that protects the dispenser’s lining before it is completely
installed. However, it must be removed immediately after installation to ensure an
easy removal that will not damage painted surfaces. Use proper products (avoid
harmful solvents) to eliminate any glue residues.
