UNPACKING
-WARNING
HEAVY ITEM
Carefully remove the DD3000 dehumidifier unit from its transit box and
visually check for signs of transit damage. If there is evidence of damage DO
NOT attempt to operate the unit, call your supplier for advice. Do not discard
the packing, it will be useful when transporting the dehumidifier unit in the
future.
INTRODUCTION
Dehumidifiers remove moisture from the air that is circulating through the unit.
The resulting reduction of relative humidity helps prevent rust, rot, mould,
mildew and condensation within the room, or other enclosed spaces where
the dehumidifier is used.
The DD3000 is of the desiccant wheel type designed to dry air by passing a
large volume of air, the “process” air through a slowly rotating Silica gel rotor.
Silica gel is a hygroscopic material that absorbs moisture direct from the air.
As the air passes through the rotor the humidity of the air is reduced, whilst
the moisture content of the rotor is increased. A smaller volume of air, the
reactivation air, is heated by an internal heater and passes through a portion
of the rotor in the opposite direction. As this heated air passes through the
rotor it will “reactivate” it by removing the moisture content from the silica gel
material. The reactivation air will leave the humidifier as warm, moist air and
must be vented to outside of the building.
Continuous circulation of the air through the dehumidifier unit gradually
reduces the relative humidity in the space.
The DD3000 dehumidifier is a robust unit designed to control the humidity in
the enclosed space in which it is placed. The casing is fabricated from Steel
then painted and has been designed for the exacting conditions which can
prevail in offices, shops, houses, restaurants, public houses etc. It combines
compactness with high reliability and strength.
The unit is thermally protected and will automatically switch off in excessive or
abnormal conditions.
The dehumidifier has two separate filters. One in the “process” air inlet and
one in the “reactivation” air inlet, used to clean the air entering the
dehumidifier.
