EQUIPMENT SIZING GUIDELINES <br />If primary load is cooling, size the same as any other air conditioning system. If primary load is heating, use the chart below for maximum <br />size for heating. <br />MAXIMUM RECOMMENDED EQUIPMENT SIZE - HEATING <br />COOLING LOAD (tons) <br />MAXIMUM RECOMMENDED EQUIPMENT SIZE FOR HEATING* <br />1 <br />24 <br />1.5 <br />24 <br />2 <br />36 <br />2.5 <br />36 <br />3 <br />48 <br />3.5 <br />60 <br />4 <br />60 <br />5 <br />60 <br />* Make sure duct work is capable of delivering required airflow. Make sure combination rating exists for desired indoor and outdoor combination. <br />MIN/MAX AIRFLOW TABLES <br />The indoor airflow delivered by this system varies significantly <br />based on outdoor temperature, indoor unit combination, and <br />system demand. The airflows on these tables are for duct design <br />considerations. <br />Duct systems capable of these ranges will ensure the system will <br />deliver full capacity at all outdoor temperatures. <br />Minimum and maximum compressor stage can be adjusted from <br />these numbers in the Evolution® Connex- Heat Pump Setup <br />screen. <br />Cooling - Comfort Mode <br />Minimum Cooling <br />(Dehum or Zoning) <br />Size <br />Max Stage 5 Airflow <br />Max Stage 1 Airflow <br />1-Ton <br />420 <br />300 <br />300 <br />2-Ton <br />739 <br />300 <br />300 <br />3-Ton <br />990 <br />300 <br />300 <br />4-Ton <br />1389 <br />542 <br />457 <br />5-Ton <br />1600 <br />700 <br />600 <br />Cooling - Efficiency Mode <br />Size <br />Max Stage 5 Airflow <br />Max Stage 1 Airflow <br />1-Ton <br />420 <br />300 <br />2-Ton <br />825 <br />585 <br />3-Ton <br />1050 <br />600 <br />4-Ton <br />1400 <br />875 <br />5-Ton <br />1800 <br />975 <br />Heating - Comfort Mode <br />Size <br />Max Stage 5 Airflow <br />Max Stage 1 Airflow <br />1-Ton <br />409 <br />300 <br />2-Ton <br />819 <br />300 <br />3-Ton <br />1014 <br />300 <br />4-Ton <br />1550 <br />429 <br />5-Ton <br />1600 <br />500 <br />Heating - Efficiency Mode <br />Size <br />Max Stage 5 Airflow <br />Max Stage 1 Airflow <br />1-Ton <br />600 <br />300 <br />2-Ton <br />825 <br />585 <br />3-Ton <br />1200 <br />700 <br />4-Ton <br />1600 <br />1000 <br />5-Ton <br />1600 <br />900 <br />Cooling Max Mode <br />Size <br />Max Stage 5 Airflow <br />Max Stage 1 Airflow <br />1-Ton (550 cfm/ delivered ton) <br />780 <br />434 <br />2-Ton 24 <br />850 <br />585 <br />2-Ton (25) (550 cfm/ delivered ton)* <br />1350 <br />510 <br />3-Ton <br />1200 <br />600 <br />4-Ton <br />1600 <br />875 <br />4-Ton-49 <br />1450 <br />875 <br />5-Ton <br />2000 <br />975 <br />Heating Max Mode <br />Size <br />Max Stage 5 Airflow <br />Max Stage 1 Airflow <br />1-Ton (550 cfm/ delivered ton) <br />600 <br />300 <br />2-Ton (24) <br />850 <br />585 <br />2-Ton (25) (550 cfm/ delivered ton)* <br />850 <br />585 <br />3-Ton <br />1200 <br />700 <br />4-Ton <br />1600 <br />1000 <br />5-Ton <br />2000 <br />900 <br />* Serial number beginning with 0115E and newer <br />LEGEND:: <br />Max Capacity Airflow - Stage 5 airflow varies depending on conditions. This Is the highest airflow the system will attempt to deliver in this particular mode. Ductwork for <br />non -zoned systems should be sized for this airflow to ensure the system can deliver full capacity when needed. Improper duct design may result in excessive airflow noise <br />and/or cutback occurrences at max airflow conditions. <br />Highest Min. Capacity Airflow - Stage 1 airflow also varies depending on conditions. In zoned systems, each zone must be capable of delivering this airflow, for the <br />system to deliver full capacity into the zone. Otherwise, airflow may be diverted to other zones or cutback may occur. <br />Min Cooling (Dehum or Zoning) - Lowest airflow the system will deliver. May operate down to this airflow In dehumidification mode or in zoning applications where <br />ductwork restrictions have caused the blower to cut -back. <br />
