A. BEFORE YOU BEGIN
1. PRODUCT DESCRIPTION
The dehumidifier is used to remove excessive moisture from the air. The resulting
reduction in relative humidity protects buildings and their contents from the adverse
effects of excess humidity.
The environmentally friendly R290 is used as the refrigerant. R290 has no damaging
influence on the ozone layer (ODP), a negligible greenhouse effect (GWP) and is
available worldwide. Because of its efficient energy properties, R290 is highly suitable as
a coolant for this application. Special precautions must be taken into consideration due
to the coolant's high flammability.
