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. For Electric
heat KW range per specific voltage, see table PD-10.
6. Filter dimensions listed are nominal. For actual filter
and rack sizes see the Unit Installation, Operation,
Maintenance Guide.
