Notes:
1. Cooling Performance is rated at 95°F (35°C) ambient, 80°F (26.7°C) entering dry bulb, 67°F (19.4°C) entering wet
bulb and nominal cfm listed. ARI rating cfm is 350 cfm/ton for this product. 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. Rated accordance with ARI Standard 340/360-00.
2. Condensing Unit Only Gross Cooling Capacity rated at 45°F (7.6°C) saturated suction temperature and at 95°F
(35°C) ambient.
3. ARI Net Cooling Capacity is calculated with matched blower coil and 25 ft (7.6 m) of 1.375, 0.500 OD interconnect-
ing tubing. EER and/or SEER are rated at ARI conditions and in accordance with DOE test procedures. Integrated
Part Load Value is based on ARI Standard 340/360-00. Units are rated at 80°F (26.7°C) ambient, 80°F (26.7°C) entering dry
bulb, and 67°F (19.4°C) entering wet bulb at ARI rated cfm.
4. ARI Sound Rating is rated in accordance with ARI Standard 270 or 370.
5. System Data based on maximum linear length 80 ft (26.7 m)Maximum lift: suction 60 ft (18.3 m) liquid 60 ft (18.3
m) For greater lengths, refer to refrigerant piping applications manual.
6. Outdoor Fan cfm is rated with standard air-dry coil outdoor.
7. Refrigerant (operating) charge is for condensing unit (all circuits) with matching blower coils and 25 ft (7.6 m) of
interconnecting refrigerant lines.
