(1) Based on 12/7°C water temperature and 30°C ambient with a 20% Ethylene Glycol Water Concentration as quoted in Capacity Data – DX
Mechanical Cooling , on page 20.
(2) EER is the DX (Mechanical) Output Duty

Nominal Input.
(3) Based on flow rate at 12/7°C water temperature and 30°C air on coil, 12°C return water temperature @ 5°C ambient with a 20% Ethylene Glycol
Water Concentration.
(4) Based on standard unit, for units fitted with options, please contact Airedale. Machine weight includes refrigerant charge; operating weight includes
refrigerant charge and water volume.
