OPERATING LIMITS

If the appliance is supplied with chilled water, the condensation forming on the heat exchanger will be drained via the condensation drain connection. At very low chilled water temperature and very high humidity, condensation may form on components other than the heat exchanger. This is not collected in the condensation drain, but might drip from under the appliance. To avoid this, a minimum permitted water temperature must be taken into account in function of the relative humidity and temperature of the ambient air.
