�Rated in accordance with ARI Standard 340/360 and certified to ARI. Integrated Part Load Value tested at 80�F (27�C) outdoor air temperature.
Cooling Ratings� 95�F (35�C) outdoor air temperature and 80�F (27�C) db/67�F (19�C) wb entering indoor coil air.
High Temperature Heating Ratings� 47�F (8�C) db/43�F (6�C) wb outdoor air temperature and 70�F (21�C) entering indoor coil air.
Low Temperature Heating Ratings� 17�F (-8�C) db/15�F (-9�C) wb outdoor air temperature and 70�F (21�C) entering indoor coil air.
NOTE � ARI capacity is net and includes indoor blower motor heat deduction. Gross capacity does not include indoor blower motor heat deduction.
�Using total air volume and system static pressure requirements determine from blower performance tables rpm and motor output required. Maximum usable output of motors
furnished by Lennox are shown. In Canada, nominal motor output is also maximum usable motor output. If motors of comparable output are used, be sure to keep within the service
factor limitations outlined on the motor nameplate.
