3 PRE-INSTALLATION PREPARATIONANDGUIDELINES
NOTE: Before installing unit, determine whether any building alterations are required to run piping,
wiring and ductwork. Follow all unit dimensional drawings and refer to the submittal engineering
dimensional drawings of individual units for proper clearances.
Refer to Table 2.2 on page11, and submittal drawings to determine the type of system being installed
and anticipate building alterations, piping and ductwork needed.
The unit dimensions, pipe-connection locations, and piping schematics are described in the submittal
documents included in the Submittal Drawings on page93.
• Verify that the floor is level, solid and sufficient to support the unit. See 3.6 on page22 for unit
weights.
• Confirm that the room is properly insulated and has a sealed vapor barrier.
• For proper humidity control, keep outside or fresh air to an absolute minimum (less than 5% of
total air circulated in the room).
• Do not install a Liebert® DSE in an alcove or at the end of a long, narrow room.
• Install the units as close as possible to the largest heat load.
• Allow at least the minimum recommended clearances for maintenance and service. See the
appropriate submittal drawings for dimensions.
We recommend installing an under-floor water detection system. Contact your Vertiv representative for
information.
