Caution

1.1 Inspection
Upon arrival of the unit, and before unpacking it, verify that the delivered equipment matches the bill of lading.
Examine the packaging for any signs of mishandling or damage. Inspect all items for damage, visible or concealed.
Report any damage immediately to the carrier and file a damage claim. Send a copy to Emerson Corporation or to
your sales representative.
1.2 Handling
Always keep the unit vertically upright and do not leave it out in the open.
If possible, transport the Liebert.CRV using a forklift or pallet jack. Otherwise use a crane with belts or cables
and spreader bars to protect the unit’s sides from damage.
If using a forklift or pallet jack, make sure the forks (if adjustable) are spread to the widest distance that fit under
the skid. Also, ensure the fork length is suitable for the unit length.
When moving the packaged unit, do not lift it any higher than 152 mm off the ground. Exercise great care if the
unit must be lifted higher than 152 mm; any personnel not directly involved in lifting the unit must be at least 5m
from the unit.
Take care of the Center of Gravity indicated on the package.
