• For CL115, 140, 155, 170, a minimum supply duct free area of 220, 220, 240, 260 sq. in. respectively, must be
maintained at all times during heating the cycle.
• For CL115, 140, 155, 170, a minimum return duct free area of 250, 250, 280, 300, sq. in. respectively, must be
maintained at all times during heating the cycle.
• A/C coils installed above heat exchanger should be located over oil section.
• A/C coils installed above heat exchanger should be located as high as possible and no less than 12 inches
above the top of the heat exchanger.
