3 PRE-INSTALLATION PREPARATION AND GUIDELINES
NOTE: Before installing unit, determine whether any building alterations are required to run 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 and ductwork needed.
The unit and anchor dimensions are described in the submittal documents included in the Submittal
Drawings on page 53.
• Verify that mounting surface/roof top is level, solid and sufficient to support the unit. See Table
3.3 on page 15, for unit weights.
• Verify that the support structure for the unit (concrete or other type) has a flat, regular
surface and is adequate to support the unit operating weight.
• Verify that adequate water-control/drain system is in place. If connecting the drip-pan clean-
out line, refer to the appropriate submittal document in Table 3.1 below, for the clean-out line
location and port size.
• Verify that the high-voltage electric-supply lines are adequately sized based on the electrical
specification on the unit's name plate and meet local code.
• Verify that the utility electric-supply lines (lights and outlet) are adequately sized and meet
local code.
• Verify that all control and communication wiring are properly routed to the unit control panel
and meet local code.
• Confirm that the conditioned space has a proper envelope and vapor barrier.
• Handle outside air and humidity control externally to the Liebert® DSE500 unit. The DSE500
does not control humidity and is not intended to handle outside air.
• Allow at least the minimum recommended clearances for maintenance and service. See the
appropriate submittal documents for dimensions in Submittal Drawings on page 53
• Ensure that there is no obstruction when installing ductwork connections and transitions to
minimize friction losses and turbulence.
