4 PRE-INSTALLATION PREPARATION AND GUIDELINES
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 page 9, 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 page 37.
• Verify that the floor is level, solid and sufficient to support the unit. See Table 3.3 on page 12
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® CW 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.
4.1 Site Preparation
Prepare the site for installation prior to arrival and unloading of the unit.
• If installing the unit on a concrete slab or housekeeping pad, sweep the concrete clean and
mark the final position of the unit(s) on the slab.
• Verify that all required clearances as specified by Vertiv are met.
• Mark the direction of the final unit placement to avoid accidental reversal of the unit.
• Protect stub-outs for electric conduit and any other projections against damage and clearly
mark their locations.
• Locate and mark the high point on the slab. This step is critical for the placement of multiple,
joined units.
• If installing on a structural-steel support structure, verify suitability of the supports beneath
the unit(s).
4.1.1 Preparing a Concrete Slab
1. Sweep the slab broom clean.
2. Lay out the final location of the unit on the slab, using either chalk line or tape, see Figure 4.1
on the next page.
3. Using a laser level or optical level, locate the high point on the slab and mark it, see Figure 4.1
on the next page.
