Certied in accordance with the ULE certication program, which is based on AHRI Standard 340/360; 95°F outdoor air temperature and 80°F db/67°F wb entering
evaporator air; minimum external duct static pressure.
2
Integrated Energy Efciency Ratio certied and tested according to AHRI Standard 340/360..
3
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 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.
