2. Continuous draining
• Water can be automatically emptied into a floor drain
by attaching the unit with a water hose (Id
not included) with a female threaded end (ID: M = 1”,
not included).
• Remove the plastic cover from the back drain outlet
of the unit and set aside, then insert the drain hose
through the drain outlet of the unit and lead the
drain hose to the floor drain or a suitable drainage
facility. (See Fig. 9 and Fig. 10)
• When you remove the plastic cover, if there is some
water in the back drain outlet of the unit you must
dry it. Make sure the hose is secure so there are
no leaks and the end of the hose is level or sloping
downwards to let the water flow.
• Direct the hose toward the drain, making sure that
there are no kinks that will stop the water flowing.
• Select the desired humidity setting and fan speed on
the unit for continuous draining to start.

Positioning the Unit
A dehumidifier operating in a basement will have little or no effect in drying an
adjacent enclosed storage area, such as a closet, unless there is adequate circulation
of air in and out of the area. (See Fig. 13)
• Do not use outdoors.
• This dehumidifer is intended for indoor
residential applications only. This
dehumidifier should not be used for
commercial or industrial applications.
• Place the dehumidifier on a smooth,
level floor strong enough to support
the unit with a full bucket of water.
• Allow at least 8” of air space on all
sides of the unit for air circulation (at
least 16” for air outlet).
• Place the unit in an area where the
temperature will not fall below 41°F
(5°C). The coils can become covered
with frost at at lower temperatures,
which may reduce performance.
• Place the unit away from any clothes
dryer, heater or radiator.
• Close all doors, windows and other
outside openings to the room.
