ACCESSORIES DISCHARGE AIR NOZZLE KIT ASSEMBLY The optional discharge nozzle kits are used to direct the conditioned air to a specific target area. By concentrating the airflow, the nozzles increase the air velocity towards production lines to cool personnel and/or equipment. In server rooms, the nozzles can be used to direct the airflow through the rack to remove the hot air from the area of the equipment. - Page 11 ACCESSORIES EVAPORATOR RETURN AIR PLENUM Evaporator return air plenums are available for installations where it is required to duct air to the inlet of the evaporator. The evaporator return air plenums allow the user to connect round duct (flexible or rigid) to the return air intake to reduce air noise and increase the number of options for solving difficult cooling problems.
- Page 12 ACCESSORIES DISCHARGE DUCT ADAPTER Discharge duct adapters are available for applications where ducted evaporator discharge is required. The adapters can be easily installed on the unit without fasteners, and be installed for either vertical or horizontal ducting. The standard discharge grille is removed and the adapter is attached in the grille opening. DDA-6 for OWC12, converts the evaporator discharge to a 6-inch diameter round duct.
