7.3 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 damage, report it to
the shipper and to your Liebert supplier.
7.4 Installing the Ceiling Units
WARNING! Risk of ceiling collapse and heavy unit falling. Can cause building damage, serious
injury or death. Verify that the supporting roof structure is capable of supporting the weight of
the unit(s) and the accessories during installation and service. (See Ceiling Unit Weights
above.) Securely anchor the top ends of the suspension rods and verify that all nuts are tight.
The evaporator unit and indoor 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 building 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 three
inches (76.2mm).
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.
Using a suitable lifting device that is rated for the weight of the unit (see Ceiling Unit Weights above),
raise the unit up and pass the threaded rods through the four mounting holes in the flanges that are part
of the unit base.
