AHRI Certified to AHRI Standard 340/360:
1
Cooling Ratings - 95°F outdoor air temperature and 80°F db/67°F wb entering indoor coil air.
High Temperature Heating Ratings - 47°F db/43°F wb outdoor air temperature and 70°F entering indoor coil air.
Low Temperature Heating Ratings - 17°F db/15°F wb outdoor air temperature and 70°F entering indoor coil air.
Using total air volume and system static pressure requirements determine from blower performance tables rpm and motor output required. Maximum usable output of
2
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.
NOTE – Motor service factor limit - 1.0.
