Congratulations on your purchase of this dehumidifier. Please read this instruction manual
carefully before you use this dehumidifier.
Drier air offers greater comfort at higher room temperatures. Lower humidity reduces
growth of mold, fungus and bacteria, while creating a more conductive environment for
storage of most applications.
Besides human comfort, Dry Air storage is used for numerous applications such as Strong,
Libraries, Electronic equipment rooms, Hospitals, Pharmaceutical Storage Area, Archives,
Laboratories and for other hygroscopic material applications.
Bacteria and mould requires a high humidity to survive and multiply. If the humidity is kept
below 50% relative humidity.
Corrosion - iron and steel will not rust if the air in contact with the surface has humidity
below 50% relative humidity.
The air is laden with moisture, however the volume of moisture able to carry at any given
temperature is limited (termed saturation vapor (content). Beyond this, vapor returns to
liquid (water) state of its gaseous state.
Based on this principle, air conditioner and a refrigerant dehumidifier cools the air, lower-
ing the saturation level and thereby promoting condensation. However, an air conditioner is
controlled by its thermostat which is less effective and less efficient while a dehumidifier is
controlled by a humidistat or hygrostat which provides the desired humidity level.
Relative Humidity is a measure of how much moisture is in the air. It is the ration that
indicates the ability of the air to absorb more moisture, expressed in percent (%RH). For
more information, see also specific / absolute humidity.
The lower the percentage of RH, the lower the moisture content in the air and the greater
the air’s ability to absorb more moisture. When the air reaches 100% RH, it reaches its
saturation point and the water vapor turns to liquid, forming droplets of condensation.
