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. Tested in
accordance with ARI Standard 360.
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. |
