1 CWA2 C SERIES TM Air Handler / Chilled Water / Electric Multiposition Design With Chilled Water Coil (0-20 KW) (Upflow/Horizontal Left or Horizontal Right *) G A C F BOTTOM AIR INLET Physical Dimensions B D E Description: The CWA2-XX chilled water air handler with electric heatseries is designed for multiposition applications in closet, attic or basement installations. The 24CWA2-XX unit handles up to 800 CFM of air movement, 1.5 to 2.0 tons of cooling and up to 10 KW of electric heat. The 36CWA2-XXunit handles up to 1200 CFM of air movement, up to 3.0 tons of cooling and up to 15KW of electric heat. The 48 CWA2-XX unit handles up to 1750 CFM of air movement, 3.0 to 4.0 ton s of cooling and up to 20 KW of electric heat.the 60 CWA2-XX unit will move up to 2100 CFM of air, 3 to 5 tons of cooling and up to 20KW of electric heat. For cooling requirements, these units are designed with 2-pipe chilled water a-coils. These units are UL & ULc listed (Approved for Canada).

Standard Features: Upflow, horizontal right to left and (*) easily field converted to horizontal left to right airflow without additional parts. Drain pans are plastic, thus non-rusting. Drain pans have primary and secondary drains for either Left or Right hand connections. Pre-painted (Designer Grey) front & top is the same high quality finish Cabinet durability is ensured by using a heavy Ga. galvanized steel. All units are equipped with Time Delay Relay, factory installed (standard). All units include a 1-inch throwaway filter (standard). All units are 208/240V / 1 Phase / 60 HZ. All units are shipped with a 208/240V / 40VA transformer. All units are suitable for 0 inch clearance to combustible materials. Units are not suitable for Counterflow / Downflow applications. Blower assembly slides out for easy maintenance. Chilled water coil connections are swaged and then factory sealed with copper caps to maintain a nitrogen holding charge. Optional Extra: Factory installed Circuit Breaker on 10 KW and below models. Page Terminal Road Fort Worth, TX (817) Fax (817) Spec. CWA
