5.3 Equipment Inspection—Upon Receipt
When the unit arrives, do not uncrate equipment until it is close to its final location. All required
assemblies are banded and shipped in corrugated containers. If you discover any damage when you
uncrate the unit, report it to the shipper immediately. If you later find any concealed damaged, report
it to the shipper and to your Liebert supplier.
5.4 Packaging Material
All material used to package this unit is recyclable. Save it for future use or dispose of the material
appropriately.
5.5 Installing the Ceiling Units
The evaporator unit and condensing unit are usually mounted above the ceiling and must be securely
mounted to the roof structure. The ceiling and ceiling supports of existing buildings may require
reinforcements. Be sure to follow all applicable national and local codes. Use field-supplied threaded
suspension rods and 3/8-16 factory hardware kit.
Recommended clearance between ceiling grids and building structural members is unit height plus
3 in (76mm).
Install the four field-supplied rods by suspending them from suitable building structural members.
Locate the rods so that they will align with the four mounting holes in the flanges that are part of the
unit base.

WARNING
Risk of ceiling collapse and heavy unit falling. Can cause building and equipment damage,
serious injury or death.
Verify that the supporting roof structure is capable of supporting the weight of the unit(s) and
the accessories. (see 5.2 - Ceiling Unit Weights.)
Be sure to securely anchor the top ends of the suspension rods. Make sure all nuts are tight.
