DRAINAGE INSTALLATION
Install the included drain pipe to the draining nozzle on the machine and direct the pipe to the
desired area before operate the machine. If in need to replace or extend the drainage pipe, use 5/8"
ID (Ø16 mm) piping.
WARNING: Do not block the drainage hose. The end of the drainage pipe should not be higher than
the outlet hole. If the drainage pipe end is higher than the outlet hole, water will not drain properly
and could damage components of the unit.

SETUP AND OPERATION
KEY FUNCTIONS
POWER– Turns the unit on and o.
CONTINUOUS OPERATION – When pressed, the unit will operate continuously.
TIMER/MODE – The unit has 5 modes: Humidity, Current Time, Timed Operation On, Timed
Operation O, and Exit. Every time you pressthe Timer/Mode key it cycles to the next mode.
“+”BUTTON – When in the “SET”mode, every time you press the“+”button, it will raise the humidity
by 1%. If you hold the button down, it will add humidity more quickly. When in any of the time
modes, the “+”button adds hours. These buttons are used to set “CURRENT”time, “TIMING ON”, and
“TIMING OFF.”
“–“ BUTTON – When in the“SET”mode, every time you press the“–”button, it will lower the
humidity by 1%. If you hold the button down, it will lower humidity more quickly. When in any of the
time modes, the “–”button adds minutes. These buttons are used to set“CURRENT” time,“TIMING
ON”, and“TIMING OFF.”
HUMIDITY AND TIMER SETUP
When the machine is powered on for the firsttime there will be an audible buzz sound. Press
the POWER button to start the machine. The screen will display “Run” and“Current,”the present
humidity.
1. To set the desired humidity, pressthe TIMER/MODE button. The screen shows“Set”and the
machine enters into the set mode. When in the set mode, you can increase or decrease the
humidity from the default setting to your desired level by using the “+”or “–”buttons.
ATTENTION:
2. To set the current time, press TIMER/MODE again to see the present time. You can change the
time by using the “+”button to change hours and “–”button to change minutes.
ATTENTION: The time format is in 24 hours and the default time is set at 12:00. You can choose to
skip the current time setting by pressing the TIMER/MODE button to cycle to exit. However, if the

3. To set for timed operation, press TIMER/MODE a third time and “Timing on” will display. Use the
“+”button to change hour and the “–”button to change minutes. The timer is in 24-hour format.
4. After you press TIMER/MODE a fourth time,“Timing o ”will display. Use the“+”button to
change hour and the“–”button to change minutes.
TIP: You can choose to skip the Timing on and T by pressing theTIMER/MODE but-
ton to exit. If so, you must manually power the machine on or me by pressing thePOWER
button.
5. Press TIMER/MODE a fifth time to exit the setting mode.
OPERATIONS
Non-timed dehumidifying operation to the desired humidity level
When the timer is not set, the unit dehumidifies up to the humidity set point and automatically goes
to the standby mode when the set point is achieved. After the ambient humidity increases more
than 3%, the dehumidifying function operates again. The machine will continue working in this
pattern until it is manually powered o .
Due to the 3-minute on/o delay design to protect the working components (see On/O Delay, page
9), the humidity reading may go up more than 3% while the machine remains in the standby mode
since it is within the 3-minute delay protection period. This usually happens under conditions where
the ambient humidity is high. It is not a machine malfunction.
Timed dehumidifying operation to the desired humidity level
When the timer is set, the machine will operate according to the humidity set point (see page 7,
step 1), only after the Timing On time and before the Timing O time. Before the Timing On time
and after the Timing O time, the machine is in standby mode. Unless the power supply cord is
unplugged, the machine remembers all set points in the standby mode and will automatically
operate according to the timer setup every day.
You can manually override the timer function to start or stop the dehumidifying function by
pressing the POWER button. The machine resumes to the timer mode in the next 24-hour cycle.
AutomaticDefrost
The unit will automatically go into defrost mode when frost forms on the evaporator coil. The screen
shows“Defrost.”After 15 minutes of defrost time the unit will resume operation. When in the defrost
mode, the unit does not dehumidify.
Continuous dehumidifying operation
NOTE: Use this setting when operating this dehumidifier with a timed humidity controller.

When the machine is in continuous operation, the desired humidity set point is still remembered
but is deactivated. The machine will continuously dehumidify, no matter what the humidity set
point is, until it is manually powered off or timed off.
1. Press the CONTINUOUS OPERATION button to enter the continuous operation mode. The
screen will show“Continuous.”
2. Press the CONTINUOUS OPERATION button again to deactivate continuous operation. The
machine goes back to the mode of operating according to the humidity set point.
When there is a frost buildup, the machine will be forced to stop dehumidifying and start defrosting
automatically. The screen shows the machine in“Defrost”process under“Continuous” mode. After
the defrost function ends,“Defrost”disappears from the screen while“Continuous”still shows.
Automatic Restart
In the event of a power failure, the machine will remember what the humidity set point was and
whether the unit was in operating mode before the power failure.
When power is restored, if the unit was operating before the power failure, it automatically restarts
to operate according to the humidity set point in the non-timed mode.
Note that the unit was powered off when a power failure occurs, the unit will remain powered off
until it is turned back on.
The Automatic Restart feature allows the unit to be used with controllers and timers.
On/Off Delay
If the system is turned off after running and you wish to turn it on again, there is a 3-minute delay
before restart as protection to the working components of the unit.

1. Clean the machine with a soft wet cloth.
2. Pull out the louver on the front panel to gain access to the filter.
3. Remove the filter mesh from the unit.
4. Use a clean rag to absorb the surface dust on the filter mesh. If the filter is extremely dirty, use
tap water to flush the filter. Fully dry the filter before putting it back into the air inlet fence. A
clean filter will increase the machine’s capacity.
MAINTENANCE
10
If you will not be using the unit for an extended period of time, please store it perthe
following steps.
• Clean the lter mesh.
ATTENTION: The evaporator inside the machine has to be dried out before the unit is packed to
avoid component damage and molds. Unplug the unit and place it in a dry open area for a few days
to dry it out.
TIP: Another way to dry the unit is to set the humidity point higher than the ambient humidity to
force the fan to dry the evaporator for 30 minutes. The dehumidifying functionwill not work and the
fan can accelerate the drying process.
