�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<br />
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.<br />
�Rated in accordance with ARI Standard 340/360 and certified to ARI; 95�F (35�C) outdoor air temperature and 80�F (27�C) db/67�F (19�C) wb entering evaporator air; minimum external duct static<br />
pressure. Integrated Part Load Value tested at 80�F (27�C) outdoor air temperature. �Tested at conditions included in ARI Standard 340/360.<br />
NOTE � ARI capacity is net and includes evaporator blower motor heat deduction. Gross capacity does not include evaporator blower motor heat deduction.
