(1) Entering air 24°C/45% RH condensing water in / out: 35/40°C
(2) Machine weight Includes a refrigerant charge / Operating weight includes calculated water volume
(3) Based on air temperature of 15.5 °C leaving the evaporator coil
(4) Based upon low pressure hot water 82 °C inlet / 71°C outlet. Air on 20°C.
(5) Fan gain based on 25 Pa ESP @ nominal air volume. Fan gain figure will change as airflow and ESP change.
