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. ARI capacity is net
and includes the effect of fan motor heat. Units are suitable for operation to ±20% of nominal cfm. 17½ - 20 ton models are certified in accordance with the Unitary Large
Equipment certification program, which is based on ARI Standard 340/360-93. 25 ton model ratings shown are tested in accordance with ARI Standard 340/360-93.
2. EER is rated at ARI conditions and in accordance with ARI Standard 210/240 or 360.
3. Integrated Part Load Value is based in accordance with ARI Standard 210/240 or 360. Units are rated at 80°F ambient, 80°F entering dry bulb, and 67°F entering wet bulb at ARI
rated cfm.
4. Sound Rating shown is tested in accordance with ARI Standard 270 or 370.
5. Refrigerant charge is an approximate value. For a more precise value, see unit nameplate and service instructions.
6. Refrigerant charge for horizontal models is 21.5/14.5 per circuit.
7. Optional two inch pleated filters are also available.
8. For 380V/60Hz units, the oversized motor is used as the standard motor. Refer to oversized motor data.
*Indicates both downflow and horizontal units.
