(1) Entering air 24°C/45% RH ambient 35°C.
(2)
Fan Gain / Fan power input based upon fan operating with design airow at 25Pa ESP, these values may change with different ESP.
(3) With Standard forward curved fan motors; Machine weight includes a refrigerant charge.
(4) Backward curved EC fan options quote electrical power. All other options quote shaft power.
(5) For refrigerant charges, refer to Unit Refrigerant Charge (kg/Circuit).
(6) Based on air temperature of 15.5°C leaving the evaporator coil.
(7) Based upon low pressure hot water 82°C inlet / 71°C outlet. Air on 20°C. Refer to Low Pressure Hot Water.
