Page 6

LOW-AMBIENT COOLING GUIDELINE

The minimum operating temperature for these units in cooling mode is 55_F/12.7_C outdoor ambient without additional accessories. This equipment may be operated in cooling mode at ambient temperatures below 55_F/12.7_C when the accessories listed in Table 1 or 2 are installed. Wind baffles are required when operating in cooling mode at ambients below 55_F/12.7_C. Refer to Fig. 1 for wind baffle construction details for Legacy RNC

through Legacy Line models and Fig. 2 for Deluxe models. First production of Preferred Series units are capable of low ambient cooling only with pressure switch or Evolution UI control. Motor Master was not available. See most current Product Data for updates. Evolution Series 2-Stage units are capable of low ambient cooling only with Evolution UI control.
