3 Pre-installation Preparation
WARNING! Risk of top-heavy unit falling over. Improper handling can cause equipment damage, injury or
death. Read all of the following instructions and verify that all lifting and moving equipment is rated for the
weight of the unit before attempting to move, lift, remove packaging from or prepare the unit for installation.
CAUTION: Risk of contact with sharp edges, splinters, and exposed fasteners. Can cause injury. Only
properly trained and qualified personnel wearing appropriate, OSHA-approved PPE should attempt to move,
lift, remove packaging from or prepare the unit for installation.
NOTICE
Risk of passageway interference. Can cause unit and/or structure damage. The unit may be too large to fit
through a passageway while on or off the skid. Measure the unit and passageway dimensions, and refer to the
installation plans prior to moving the unit to verify clearances.
NOTICE
Risk of damage from forklift. Can cause unit damage. Keep tines of the forklift level and at a height suitable to
fit below the skid and/or unit to prevent exterior and/or underside damage.
NOTICE
Risk of improper storage. Keep the unit upright, indoors and protected from dampness, freezing temperatures
and contact damage.
NOTICE
Risk of a leaking coil due to freezing during improper storage. Can cause equipment and serious building
damage.

Figure 3.2 Vertiv™ Liebert® CRV CRC30 and CRC60 Clearance Requirements Unit mm (in.)
3.4 Inspecting the Unit
Upon arrival of the unit and before unpacking:
•Verify that the labeled equipment matches the bill of lading.
•Inspect that there are no visible or concealed damages on the package.
•Check that the tilt monitor indicator on the package is not red. If it becomes red, tipping has occurred.
Report damage immediately to the carrier and file a damage claim with a copy sent to Vertiv™ or to your sales
representative.
3.5 Moving the Packaged Unit
Transport the unit with a forklift. When using the forklift:
•Make sure the fork length is suitable for the width of the pallet.
•Do not tilt the unit more than 20 degrees in any direction to prevent the unit from falling over.
•Refer to the following figure for the location of the center of gravity.

3.6 Unpacking the Unit
To unpack the unit:
1. Pull straight the latches on the wooden box using a claw hammer.
2. Remove the side wooden panels. And then remove the top wooden panel and the cushioning from the top of the
unit.
3. Remove the starch wrap that attach the ramp to the unit. Remove the ramp and set it aside until needed for
moving the unit. Remove the bag around the unit.
