(1) Entering air 24°C /45°C RH ambient 35°C
(2) Machine weight excludes a refrigerant charge
(3) For refrigerant charges, refer to Unit Refrigerant Charge (kg/Circuit).
(4) Based on air temperature of 15.5°C
leaving the evaporator coil
(5) Based upon low pressure hot water 82°C inlet/71°C outlet. Air on 20°C
(6) Fan gain based on 25Pa ESP @ Nominal air volume. Fan gain figure will change as airflow and ESP change
