1
Certified in accordance with the ULE certification program, which is based on ARI Standard 340/360; 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 pressure.
2
Tested at conditions included in with ARI Standard 340/360; 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 pressure.
3
Integrated Part Load Value tested at 80_F (27_C) outdoor air temperature.
4
Using total air volume and system static pressure requirements determine from blower performance tables rpm and motor output required. Maximum usable output of motors fur-
nished 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 limita-
tions outlined on the motor nameplate.
5
Stocked models are available with standard static drives. High static drives are factory installed (configure to order). Low static drive can be factory installed (configure to order) or
standard static drives can be converted to low static with field installed kit.
