¡Rated in accordance with ARI Standard 210/240 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; mini-
mum external duct static pressure.
©Sound Rating Number rated in accordance with test conditions included in ARI Standard 270.
¢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.
NOTE — Net capacity includes evaporator blower motor heat deduction. Gross capacity does not include evaporator blower motor heat deduction.
