MACHINE SETUP AND OPERATION
BUTTON FUNCTION
1. Press this button while screen light is on and unit
will automatically enter a continuous mode. The
screen will display the environmental humidity and
the compressor will turn on after the fan has run for
3 seconds. Press this button again, and the compressor
will stop with the display screen showing "- -". The unit
will then enter a standby mode; the fan will run for another
minute and stop.
2. Hold down this button until the light powers
on, then press "MINUS" and "ADD" to set the
start time. When the countdown is over, the fan
and compressor will power on. To power off the
unit, hold down this button until the button light powers
on. Press "MINUS" and "ADD" to set the stop time.
When the countdown is over, the fan and compressor will
power off. Hold down this button for 3 seconds to view
the current temperature. After 10 seconds, the display will
return to the current humidity. Hold this button to show the
current temperature.
3. The humidity can be increased by increments of
5% RH during normal mode. Hold this button for
1 second to increase the humidity.
4. The humidity can be decreased by increments of
5% RH during normal mode. Hold this button for
1 second to decrease the humidity.
Note:
A. The
default
humidity
increase
and
decrease
20%-25%-30%-35%-40%-45%-50%-55%-60%-
65%-70%-75%-80%-85%-90%
B. Environmental and machine set humidity will decide the
status of the compressor and fan. If the environmental
humidity is ≥ the machine set humidity + 3%, the
compressor and fan will begin operation. If the
environmental humidity is < the machine set humidity +
3%, the compressor and fan will cease operation. Press
the continue button for continuous mode or switch
to normal dehumidification mode to set the humidity
manually.
5. During continuous mode, the humidity setting
will be unavailable. The continuous mode light
will turn on and the screen will display the current
humidity. Press this button to switch to normal
mode where the humidity setting is available.

OPERATION
1. When the water tank is full, a red light will illuminate
followed by an alarm. The alarm will sound 15 times
before the compressor and fan power down. After the
water tank is empty, the machine will automatically
switch to its previous mode while the compressor will
remain in a 3 minute self-protection status. The alarm
will stop 3 seconds after the water tank is emptied and
replaced. The fan and compressor will start again after
3 minutes.
2. The compressor will not require the 3 minute self-
protection status if it is the first time being used. Press
"POWER" to power off or power on. Press "POWER", to
restart compressor.
3. The system features an auto memory. If all mode
settings have been completed, if there is sudden power
interruption, or if the power jack is removed, the system
will store the current status and restart at the previous
settings once power has been restored.
DEFROST FUNCTION
1. The compressor and fan will shut off when the
environmental temperature goes below 41°F or above
100.4°F.
2. Defrost Operation: Compressor will run for 30 minutes.
Once the temperature sensor reaches ≤ 30.2°F (lasts for
10 seconds), the compressor will stop, and defrosting
will begin. The fan will continue operation with the
defrost light on. Once the pipe temperature reaches
41°F or the defrost operates for 15 minutes, defrosting
will end. Note: During defrost, light will remain on
until defrost is complete.
ERRORS
1. "E1": If the temperature sensor fails, an "E1" code will
display. The system works in cycles of dehumidification
for 30 minutes and defrosting for 15 minutes. A failed
temperature sensor should be replaced.
2. "E2": If the humidity sensor fails, an "E2" code will appear
and the humidity adjustment button will not function.
The system works in cycles of dehumidification for 30
minutes and defrosting for 15 minutes. A failed humidity
sensor should be replaced.
3. "CL": When the room temperature is < 5°C (41°F), a "CL"
code will display and the machine will stop running.
4. "CH": When the room temperature is > 38°C (100.4°F) a
"CH" code will appear and the machine will stop running.
5. "LO": When the room humidity is < 20% RH, an "LO"
code will display and machine will stop running.
6. "HI": When the room humidity is ≥ 95% RH, an "HI" code
will appear and the machine will operate normally.
