OPERATION INSTRUACTIONS

Position Your Dehumidifier
Install the dehumidifier horizontally to minimize vibration and or noise.
You can adjust the feet to level the dehumidifier.
To adjust the feet,
a) Turn the nutin a clockwise direction to get the nut loosen;
b) Turn the foot in a clockwise direction to get the foot down or turn the foot in a counterclockwise direction to get the foot up;
c) Turn the nut in a counterclockwise direction to fix the foot. For best results, operate your dehumidifiers in an enclosed area.
Close all doors and windows that open to the outside to maximize water removal efficiency. Place your dehumidifier away from obstructions, and keep it away from anything that could block airflow into and out of the unit.
Plug in
IMPORTANT
Please let the dehumidifier sit outside the box for 24 hours before initial plugging in.
Uncoil the power cord and plug it firmly into a properly grounded 110-120 volt AC outlet After plugged in, the control panel will light up for 1-2 seconds and then goes off, which is the normal self-diagnose process and does not require any user intervention.
Turn the Dehumidifier On
Press the POWER button to turn the dehumidifier on. Typically, the dehumidifier will run in the default setting with set humidity 30% at low fan speed.
Understand the Control Panel
The control panel on the dehumidifier has an LCD screen and 4 buttons. Press the POWER Button to turn the dehumidifier on. The LCD screen will light up and display the readouts as below. (1) What is on the LCD Screen?
Big Font Digital Number (43 RH% on the above illustration) is humidity percentage reading of the inlet air that the dehumidifier detects which is similar to the room humidity level. When you are pressing the 1 or | button to set a desired humidity percentage value, the big font digital number will turn to display the setting value and flash.
Small Font Digital Number (77°F on the above illustration) is temperature reading of the inlet air which is similar to the room temperature. However, if the timer function is being set or has been activated, the small font digital number will turn to display the timer setting value or time remaining.
Running Icon: Running icon flickers typically because the compressor has not kicked in. It usually happens 1) when the dehumidifier is under the 3-minute compressor delay status; 2) when the dehumidifier is programmed to delay-start (AUTO ON TIMER).
wet Controller Icon: Wet Controller Icon flickers when the room humidity level (inlet humidity reading) is 3% lower than the set humidity.

When you see the “wet controller” icon illuminating while setting up, it typically means the set humidity level is not 3% lower than the inlet humidity reading. Please make sure the set humidity value is at least 3% (10% recommended) lower than the inlet humidity reading.
In Humidistat Mode, if you see “wet controller” icon illuminating after running the dehumidifier for a while, it means the dehumidifier has got the room humidity down to the set point and the dehumidifier enters into standby mode.
Defrosting Icon: The dehumidifier begins to defrost when the frost has accumulated on the interior of the dehumidifier. When the dehumidifier is defrosting, the fan is running, but the compressor is not, the defrost icon is flashing. The dehumidifying function will cease until the frost has melted. When defrosting is complete, the defrosting Icon will disappear and the dehumidifier begins to dehumidify again automatically.
Note: The frequent defrost process indicates that the room temperature is too cold. Therefore, if the room temperature is lower than 60°F, please consider adding heat to promote proper drying.
Fan Icon: The fan icon illuminates when the fan is running.
water Droplets Icon: The water droplets icon illuminates when the compressor kicks in, which means the dehumidifier is dehumidifying. When the compressor delays to start due to the 3-minutes delay system, this icon flickers.
Timer Icon: Timer icon illuminates when the timer function is enabled.
(2) Understand the Control Buttons
Power Button: Press to turn the dehumidifier ON or OFF.
Up Button: Press to increase the set-point of humidity level or timer.
Down Button: Press to decrease the set-point of humidity level or timer.
Timing/Function Button: Press once to check the settings. Press and hold for 3 seconds to enter Timer setting system.

General Operation Quick Guide
(1) Turn the dehumidifier on
Press the Power Switch to turn the dehumidifier on.
(2) Set a desired humidity percentage value
Press tor button to set your desired humidity percentage value between 10%-98% in increment of 1%. 40%-60% is a general humidity setting guide. After selected the target value, press Timing/Function Button to confirm your setting, or let the setting be registered automatically after 5 seconds of no operations on the control panel.
Note:
– The dehumidifier with a humidistat will stop and start automatically to maintain room humidity level within a range of 3% of the set point.
For example, if the set humidity is 50%,
-when the inlet humidity level the dehumidifier detects is 47%, 3% lower than the set humidity, the dehumidifier will automatically stop and enter into “wet controller” mode.
-when the inlet humidity level the dehumidifier detects raises to 53%, 3% higher than the set humidity, it will automatically restart.
– However, if the set humidity level is equal to or lower than 30, the dehumidifier will enter CONTINUOUS MODE where the dehumidifier will run continuously.
(1) Turn the dehumidifier off
Press the Power Switch to turn the dehumidifier off.
Note: To protect the compressor, the fan will continue to operate for 5 seconds after the dehumidifier has shut off. So please do not disconnect the power cord to force the dehumidifier to stop. Always use the power button.
Timer Setting
The TIMER function enables you to either delay AUTO-ON or delay AUTO-OFF the dehumidifier in the choice from 1 hour to 24 hours.
– Setting an AUTO-ON timer: When the dehumidifier is off, selecting Timer will turn the dehumidifier on in the hours that will be set.
– Setting an AUTO-OFF timer: When the dehumidifier is on, selecting Timer will turn the dehumidifier off in the hours that will be set.
Follow the below steps to set the TIMER:

Press and hold the Timing/Function Button for about 3 seconds, until you see the TIMER icon lights up and the small font digital number changes into 00, and flashes;
Adjust the timer setting by pressing 1 or | button repeatedly to change the delay timer at 1-hour increments, up to 24 hours.
After selected the target timer value, press Timing/Function Button to confirm your setting, or let the setting be registered automatically after 5 seconds of no operations on the control panel.
The small font readout will count down the time remaining (8,7,6, etc.) until the dehumidifier either starts or stops.
To disable the timer function, manually turn ON/OFF the dehumidifier, or set the timer to 00 H..
Note:
• Before entering the AUTO ON TIMER setting, make sure power is being supplied to the dehumidifier.
• For the AUTO ON setting, please turn on the dehumidifier to select a desired humidity level Otherwise, the humidity maintained will be the same as the previous setting
• You can only set AUTO ON timer when the dehumidifier is off or set AUTO OFF timer when the dehumidifier is on, but not be able to set both AUTO ON and AUTO OFF timer at the same time.
• The TIMER will ONLY function one time instead of cycling the dehumidifier on or off indefinitely.
• The TIMER function will be disabled when the dehumidifier has been powered on/off manually.
• Set the timer as 00, the timer function will not be activated.

Drain Collected Water
(1) Drain by Internal Pump
The dehumidifier has an internal pump that helps to drain the condensation water freely.
When using the pump feature,
• The Gravity Drain Outlet needs to be sealed by the included stopper;
• Connect the drain hose to the Pump Drain Outlet;
• Place the unattached end of the hose in a sink, bucket, pump sump, or out of a window – anywhere that water can drain out safely. ( Ensure there are no kinks or other obstructions that will stop the water to flow.)
NOTE:
• If you use a bucket or other container for water collection, check it regularly to prevent overflows
• The drain hose for the water pump can drain vertically up to 16ft. More than 16ft may cause water back up to the pump resulting in leakage
• If the drain hose is too long, water may not drain completely, which can lead to stagnant water and mildew build up inside the hose.
• Before moving the dehumidifier, please remove the stopper from the Gravity Drain Outlet to completely drain the condensation in the internal water tray to avoid water leakage.
(2) Drain by Gravity
The collected condensation water can be drained by gravity. When using gravity to drain,
• The Pump Drain Outlet needs to be sealed by the included stopper;
• Connect the drain hose to the Gravity Drain Outlet;
• Place the unattached end of the hose to a suitable drainage facility. The drainage facility should be lower than the drain outlet of the dehumidifier. ( Ensure there are no kinks or other obstructions that will stop the water to flow.)
Smart Functions
(1) 3 Minutes Compressor Delay Mechanism
To avoid any damage to the dehumidifier, the dehumidifier will not start operation following a complete cycle until after 3 minutes. Operation will automatically start after 3 minutes. In other word, if you turn the dehumidifier off and then restart it immediately, the compressor will not kick in until 3 minutes later. During this period, you can see the RUNNING icon flashing on the LCD screen until the compressor kicks in.
(2) Auto Defrost
When the frost builds up on the evaporator coils, the compressor will cycle off and the fan will continue to run until the frost disappears. When the dehumidifier is defrosting, you can see the DEFROSTING icon light up on the LCD screen.
(3) Auto-Restart
If the dehumidifier shuts off unexpectedly due to power outage, the dehumidifier will restart with the previous function settings automatically when the power resumes.
(4) Temperature Protection Function
When the room temperature is higher than 113°F, the dehumidifier will automatically enter into HIGH-TEMPERATURE PROTECTION SYSTEM where the LCD screen displays an “HH” message and the compressor stops.
When the room temperature is lower than 40°F, the dehumidifier will automatically enter into LOW-TEMPERATURE PROTECTION SYSTEM where the LCD screen displays an “LL” message and the dehumidifier stops working.
Note: When you see HH or LL message under normal circumstances, please contact the customer service at service@colzer.com to get technical support

MAINTENANCE

To avoid possible electric shock, ensure to turn the dehumidifier off and disconnect the plug from the power source before performing any cleaning or maintenance.

Cleaning the Dehumidifier
Clean the dehumidifier housing with a soft damp cloth. Do not submerge or place water on the dehumidifier or control panel. Water may damage the electronic components of the dehumidifier. Do not use chemical solvents such as benzene, alcohol, gasoline or other heavy-duty cleaners. The surface may become damaged or deformed.
Cleaning the Air Filter
The working performance of the dehumidifier will be greatly reduced if the filter becomes blocked. The air filter should be cleaned approximately every 2 weeks and may require more frequent cleaning if there is significant dander or fur in the air. The air filter is located behind the inlet grill
Follow the steps below to clean the filter:
• Use a vacuum cleaner with a soft brush attachment to remove any large debris or dust build-up from the filter.
• Wash the filter in lukewarm, soapy water, below 40°C (104°F), or use a neutral cleaning agent.
• Rinse the filter with clean water and dry thoroughly.
• Re-install the filter.
NOTE: DO NOT operate the dehumidifier without a filter because dirt and lint will clog it, hence reducing performance.
Pump Maintenance
If the dehumidifier stops working and displays an E7 error, which means a pump malfunction, please follow the below steps to resume the operation
① Turn off the dehumidifier and unplug it;
② Remove the stopper from the Gravity Drain Outlet and plug it into the Pump Drain Outlet;
③ Connect the hose to the Gravity Drain Outlet to drain the condensation in the internal water tray out;
(Make sure to run the hose down to a suitable drainage facility that is lower than the Gravity Drain Outle of the dehumidifier.)
④ There 3 optional drainage methods to resume the operation as below:
(A) Use the Gravity Drainage: After draining out the condensation in the internal water tray, re-plug the dehumidifier and restart the dehumidifier, the dehumidifier will run and drain automatically by gravity. (Make sure to run the hose down to a suitable drainage facility that is lower than the Gravity Drain Outlet of the dehumidifier, so the condensation can be drained out by gravity.)
(B) Connect the dehumidifier to an External Pump to Drain:
• After draining out the condensation in the internal water tray, remove the cap of the External Pump terminal and plug the external pump into the dehumidifier;
• Place the other end of the hose that collected to the Gravity Drain Outlet to the external pump inlet and let the external pump drain the condensation water to your desired drainage facility.
(C) Replace the Internal Pump to Regain the Internal Pump Function:
• After draining out the condensation in the internal water tray, remove the pump cover on the side of the dehumidifier; use a screwdriver to unscrew the fixing frame that fixes the water pump;
• Disconnect the water pipe that connects to the pump;
• Place the new pump in, fixit in the fixing frame, connect the water pipe back;
• Test whether the pump works and no water leakage;
• Replace the pump cover in the dehumidifier, and then start the dehumidifier to test to make sure the pump replacement works well.
