(2) Entering air 24°C/45% RH water 7/12°C
(3) Machine weight includes a refrigerant charge / operating weight includes calculated water volume
(4) For refrigerant charges, refer to Unit Refrigerant Charge (kg/Circuit)
(5) Based on air temperature of 15.5°C
leaving the evaporator coil
(6) Based upon low pressure hot water 82°C inlet/71°C outlet. Air on 20°C
(7) Fan gain based on 25Pa ESP @ nominal air volume. Fan gain figure will change as airflow and ESP change.
