DeWalt DDR2509EE Dehumidifier User Manual


 
1) LED Readout (ROOM HUMIDITY): The LED
window displays the following information
independently:
A) Internal (Room/Environment) Relative Humidity
Conditions
B) Set Operating Relative Humidity Value.
NOTE: The LED readout is programmed to default to
display the ambient relative humidity conditions.
To view the Set Operating Relative Humidity Value,
press the “up” or “down” button (once) and the set RH
operating value will flash for approximately 5 seconds in
the LED window, then revert back to display the internal
RH value.
2) ON/OFF Button: Each time this button is pressed the
unit turns ON (adjacent indicator light illuminates) or Off
(adjacent indicator light is not illuminated)
3) CONTINUOUS: Used for Continuous Dehumidifier
Operation (unit will run non-stop).
NOTE: Humidity values (settings) cannot be
programmed in this mode. The adjacent (green) indicator
light illuminates to signify the “continous” mode is
currently in operation.
4) HUMIDITY UP: This button allows you to increase
the relative humidity setting. Each time this button is
pressed, the RH value setting is increased incrementally
by 5% (ranging from 35% - 80%)
5) HUMIDITY DOWN: This button allows you to
decrease the relative humidity setting. Each time this
button is pressed the RH value setting is decreased
incrementally by 5% (ranging from 80% - 35%).
6) HIGH FAN: The adjacent (green) indicator light
illuminates when HIGH FAN is selected.
7) LOW FAN: The adjacent (green) indicator light
illuminates when LOW FAN is selected.
8) WATER FULL INDICATOR: This (red) light
illuminates under the following conditions:
A) When the internal water tank is not properly installed
inside the cabinet.
B) When the internal water tank is full. The water tank
must be emptied and replaced back in the cabinet before
normal operating conditions can resume.

LIGHT FUNCTION
Power Light (Green):
When the unit is first connected to an electrical outlet,
the (green) power light will not light until the “on/off”
button is pressed. When the “on/off” button is activated,
the power light turns to a state “on” condition. The
dehumidifier will automatically default to the memory
setting (see Memory Setting below for details).
IMPORTANT NOTE: Depending on the humidity
conditions of the surrounding environment, the
dehumidifier may not start automatically when the
“on/off” button is pressed (see dehumidifier operating
instructions for details). In the event of a power failure,
the unit will default to the last program setting that was
used when power is restored.
Water Full Indicator Light (Red):
When the water tank is full and/or incorrectly positioned
inside the cabinet, the (water full) red light turns on and
remains on until such time the tank is emptied and/or
correctly re-positioned. This condition will result in the
immediate shut down of the dehumidifying system (both
compressor and fan motor operation are terminated).
This is a safety feature. When the water tank is emptied
and/or correctly re-positioned, the dehumidifier will
resume operation automatically. NOTE: It may take
several minutes before operating conditions resume.
Factory Default Setting: Each time the unit is
disconnected /re-connected and/or in the event of a
power failure, the electronic circuit board automatically
defaults to the following factory setting:
Humidity Setting: 60%
Fan Speed: High
NOTE: In the event of a power failure, all previous
settings are automatically erased/cancelled. If your
program setting was different than above (default setting)
it will be necessary to re-program your settings. When
the unit is switched “off” manually (using the on/off
keypad) the unit will always default to the last program
setting that was used.
