(i)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. Certified in accordance with the Unitary Large Equipment certification program, which is based on ARI Standard 340/360-00.

(ii)Condensing unit only gross cooling capacity rated at 45°F saturated suction temperature and at 95°F ambient.

(iii)ARI net cooling capacity is calculated with matched blower coil and 25 feet of 1 3/8" or 1/2" OD interconnecting tubing.

(iv)EER is rated at ARI conditions and in accordance with DOE test procedures.

(v)Integrated part load value is based on ARI Standard 340/360-00. Units are rated at 80°F ambient, 80°F entering dry bulb (DB), and 67°F entering wet bulb (WB) at ARI rated cfm.

(vi)Sound rating shown is tested in accordance with ARI Standard 270 or 370.

(vii)Refer to refrigerant piping applications manual for line sizing and line length.

(viii)Refrigerant (operating) charge is for condensing unit (all circuits) with matching blower coils and 25 feet of interconnecting refrigerant lines. All units are supplied with a small nitrogen holding charge only.
