Tested at conditions included in the USE certification program, which is based on AHRI Standard 340/360; 35 C (95 F) outdoor air temperature and 27 C (80 F) db/9 C (67 F) wb entering evaporator air; minimum external duct static pressure while operating at rated voltage and air volumes. 2 Integrated Energy Efficiency Ratio tested at conditions included in AHRI Standard 340/360 while operating at rated voltage and air volumes. 3 Using total air volume and system static pressure requirements determine from blower performance tables rev/min and motor output required. Maximum usable output of motors furnished are shown. See Belt Drive Specification Table for 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. Landmark Packaged Gas / Electric 52.8 to 88 kw 50hz / Page
