DEHUMIDIFIER
Control Panel Operation Instructions
Product Introduction Function Description
DEHUMIDIFIER
Our dehumidifiers are designed to reduce the humidity in the installed space,
making it suitable for human living and storing items. Equipped with branded
compressors and microcomputer humidity control, our company's dehumidifiers
feature intuitive humidity display, sleek design, superior performance, and easy
operation. They are widely used in scientific research, industrial settings, medical
facilities, instrumentation, goods storage, underground construction, computer
rooms, data rooms, archives, warehouses, and bathhouses, among other places.
They prevent damage caused by dampness, corrosion, and mold to instruments,
computers, telecommunications materials, goods, and data.
1. Humidity Control:
When the set humidity is reached, the fan and compressor shut off together; when
the humidity exceeds the set level, the fan and compressor operate together.
Notes:
● When the humidity set value is at its lowest, it defaults to continuous dehumidifi-
cation mode.
● If the humidity sensor malfunctions, it defaults to continuous dehumidification
mode.
● If the coil sensor malfunctions, it switches to fixed timed defrost mode (refer to
defrosting method).
● Upon startup, there is a 3-second delay before the compressor starts, and upon
shutdown, there is a 3-second delay before the fan stops.
● If the humidity drops to the compressor shutdown condition, there is a 10-second
delay before the fan stops.
● Power-off memory: In the event of a sudden power outage while the system is
running and the power plug is not securely inserted, the system automatically stores
the current operating state. Upon the next power-up, the system will automatically
resume the previous operating state before the power outage.
2. Specific Function Description:
Upon initial power-up, press the power button power to enter the startup mode. The
default humidity is set to 50% RH, displaying the current humidity and temperature.
The entire unit operates with both the compressor and fan starting up.
Press the setting button "mode" to enter the timer setting function. Press the "+" or
"-" buttons to set the timer for shutdown. At this time, the timer indicator on the
screen flashes. Press the "+" or "-" buttons to adjust the time. Each press increases or
decreases the display incrementally. The setting range is from 0 to 24 hours, with a
default of 0 hours. If there is no operation on the interface for 5 seconds, the system
will automatically execute the current timer setting.
Press the setting button “mode” again to enter the humidity adjustment setting
function. Press the "+" or "-" buttons to adjust the humidity setting. The humidity
control range cycles between "10% - 95% - CO". The "CO" mode is the forced dehu-
midification mode, which is not restricted by temperature and humidity. In this
mode, both the fan and compressor run continuously.

2. If the above issues still cannot be resolved, please contact sean@edendi-
rect-brand.com or authorized dealer directly. Do not dismantle the machine without
authorization.
3. When the machine is running, you may hear the sound of refrigerant circulation,
which is a normal phenomenon.
4. The machine will emit hot air from the outlet, causing the room temperature to rise
by 34-37℉. This is normal, so please feel free to use it.
5. When moving, do not tilt the machine body more than 45 degrees to prevent
damage to the compressor.
6. The operating temperature of this machine is 41-95℉.
7. When the room temperature is below 50℉ and the ambient absolute humidity is
very low, the dehumidifier may not need to be used.
8. The air inlet and outlet must be at least 1 meter away from the wall or obstacles to
avoid affecting the dehumidification effect.
9. Accumulated dust on the air filter will affect the dehumidification effect and may
even cause malfunctions. It must be cleaned regularly, at least once a month. If there
is a lot of dust in the environment, it must be cleaned once a week or even daily.
When cleaning, gently tap the filter or use a vacuum cleaner to remove the dust on
the filter, or soak the filter in warm water (≤104℉) with a small amount of detergent,
then rinse it with clean water and air dry it.
10. If a fault code appears during the operation of the machine, turn off the machine
immediately and report it to the after-sales staff for repair.
Continuous operation of the machine for 24 hours will affect its service life. It is
recommended to stop the machine for 2 hours after every 10 hours of operation. If
there are special requirements for continuous operation for 24 hours, the machine
must be supervised by dedicated personnel. Otherwise, in case of accidents, the
company will not be liable.

Special Reminder
DEHUMIDIFIER
Specification Overview
DEHUMIDIFIER
1.Special Reminder to Users:
1. The humidity sensor is a precision component. Its use in environments with strong
corrosive gases and high dust levels may cause the sensor to malfunction.
2. This machine does not have explosion-proof capabilities. It is strictly prohibited to
use it in environments with flammable or explosive gases, dust, chemicals, biological
products, or other special requirements.
3. If the machine is damaged due to use in the above environments, it is not covered
by the warranty.
4. When installing this machine, grounding protection measures must be taken to
ensure safety during use.
5. Water discharge will occur after the machine has been running for a period of time.
Please pay attention to proper drainage.
6. To reduce malfunctions and extend the lifespan, avoid using excessive force when
operating the buttons.
7. The humidity sensor may have slight deviations from actual humidity due to its
position, environment, and temperature. This is a normal phenomenon.
8. During operation, cooled air will be discharged after passing through the condens-
er, resulting in higher outlet temperatures compared to ambient temperatures. The
emission of hot air is a normal phenomenon.
9. Dehumidification capacity is dependent on environmental temperature and
humidity. Higher temperatures and humidity levels result in greater dehumidifica-
tion capacity, while lower temperatures or low humidity conditions will lead to
reduced dehumidification capacity. This is a normal phenomenon.
