Notes:

1.Cooling Performance is rated at 95 F ambient, 80 F entering dry bulb, 67 F entering wet bulb. Gross capacity does not include the effect of fan motor heat. Rated and tested in accordance with the Unitary Large Equipment certification program, which is based on ARI Standard 340/360-93.

2.Heating Performance limit settings and rating data were established and approved under laboratory test conditions using American National Standards Institute standards. Ratings shown are for elevations up to 4,500 feet.

3.Steady State Efficiency is rated in accordance with DOE test procedures.

4.Refrigerant charge is an approximate value. For a more precise value, see unit nameplate and service instructions.

5.Maximum KW @ 208V = 41, @ 240V = 54.

6.Filter dimensions listed are nominal. For actual filter and rack sizes see the Unit Installation, Operation, Maintenance Guide.
