• Verify that the floor is level, solid, and sufficient to support the unit. See Table 3.3 on page24 , 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).
• 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 leak detection system. Contact your Vertiv representative for
information.
3.1 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).
