�Using total air volume and system static pressure requirements determine from blower performance tables rpm and motor output required. Maximum usable output of motors<br />
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<br />
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<br />
external duct static pressure. Integrated Part Load Value tested at 80�F (27�C) outdoor air temperature.<br />
NOTE � ARI capacity is net and includes evaporator blower motor heat deduction. Gross capacity does not include evaporator blower motor heat deduction.<br />
