1. Capacities on this chart are based on refrigerant 22.
Low ambient or lower leaving water temperatures can require the use of a
glycol solution or other fluid blends. These solutions affect unit
capacities. Please consult the factory on these or other special fluids.
2. kW imput is for compressor(s) only.
3. EER = Energy Efficiency Ratio (BTU/watt-hour). Power
imputs include compressor(s), condenser fan motor(s) and control power
