Installation Sheet
Uniflair™ SP Free-Cooling Damper Kit
Application Note
Installation of the free-cooling damper kit in a UCF unit will provide access to fresh,
outside air to assist cooling the room when the outdoor air is below the cooling
setpoint. This applies to both the UCF0341I unit and the UCF0481I unit.
This kit is only part of the fresh-air cooling system and must be accompanied by a
customer-supplied overpressure-relief damper/system that has been sized
properly for the inlet requirements of the computer room or telecom equipment
space. Schneider Electric recommends that the exhaust/relief damper should be
sized for all fresh air requirements of the space.
The maximum allowable inlet duct delta-P for the UCF units is 62.2 Pa (0.25 in.
Wg) with a recommended value of 37.3 Pa (0.15 in. Wg) for the inlet systems. The
system includes any and all items on the inlet duct system of the UCF units: rainhoods, fresh-air filtration, exterior louvers, etc., and pressure drops should be
based on the rated airflow rate of the applicable units.
NOTE: The airflow rates are 1699 m3/h (1000 CFM) for UCF0341I units and
3058 m3/h (1800 CFM) for the UCF0481I.
When grouping units in a single space, it is not necessary to install a free-cooling
damper kit in all units unless the space requires it based on the application, which
will determine how many units are required to have free-cooling capabilities. The
group control understands which units have the free-cooling capability based on
the unit controller configuration settings.
The free-cooling damper only provides the ability to use outdoor air to meet the
specified setpoint temperature. It is not, and should not be interpreted as a smoke
control or isolation device. These devices and any economizer sealing
requirements must be customer supplied.
