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. All Technical Specifications Subject to Change Without Notice.
