5.3.     HUMIDITY CONTROL
5.3.1.  When the rooms humidity value is 3% lower than the set humidity on the machine, the compressor will shut down, the fan will delay for 3 minutes and shut down; and when it’s 3% higher than the humidity value set on the machine, both the fan and compressor will operate.
5.3.2.  When the humidity is set at the minimum value, the machines default is to enter the continuous dehumidifying mode.
5.3.3.  Upon fault of the humidity sensor, it turns to the continuous dehumidifying mode.
5.3.4.  Upon fault of the coil sensor, it turns to the timing defrosting mode (See the defrosting mode).
5.3.5.  When it’s shut down, the fan will run for 10 seconds.
5.4.    PROTECTION FUNCTION
5.4.1.  Once shut down, the compressor will take 3 minutes to start. Quick start is available for the first power-on.
5.4.2.  Power off memory: For abrupt power outage or accidental unplugging, the system will automatically return to the operating state right before the `incident’, and continue at that state for the next power-on.
5.4.3.  Full water protection: When the water tank is full, the dehumidifier automatically shuts down and enters the standby state, the indicator light “Full Water” on and buzzer alarms.
5.5.  DEFROSTING MODE

run over 20 minutes, coil temperature below 0°C constantly over 30 minutes, it starts the defrosting mode.
2. Coil temperature over 5°C for a 90 second period, or defrosting time over 8 minutes, it has stopped defrosting mode.

(E1 displayed)

| 1. When the ambient temperature is over 25°C, it will not start a defrosting cycle;
2. When ambient temperature below than 25°C but higher than 15°C, the compressor runs constantly for 30 minutes, it defrosts for 10 minutes of that 30 minute period;
3. When ambient temperature below than 15°C and higher than 4°C, compressor runs constantly 20 minutes, it defrosts 12 minutes;
Temp-damp sensor faults| 1. The compressor runs constantly over 20 minutes, coil temperature below 0°C constantly run over 20 minutes, it starts defrosting mode.
Coil sensor and temp-damp sensor faults| 1. The compressor run constantly over 40 minutes, it defrosts 10 minutes;
2. Coil temperature over 5°C constantly over 90 seconds; or defrosting time over 25 minutes, it stops defrosting mode.

5.6.    TIMING AND ON/OFF FUNCTION
5.6.1.  When the machine is powered on, set timer for powering off; and when the machine is powered off, set timer for it to power on. Setting timer for both powering on and off then initiates the cycle timer mode.
5.6.2.  Set timer for powering on: When it’s powered off, press the “Timing” Button. As the “Timing On” icon flickers and the time set flickers in relevant area, press “+” or “-” to adjust the timing. The dehumidifier will make a sound once the button is pressed. When the time set increases or decreases by “1”, holding the button for 2 seconds will continually increase or decrease the time. For non-action for 10s when it’s adjusted to the required value, the dehumidifier accepts the new setting and the “Timing On” icon flickers (Ranging from 0 to 24H, and 0H as default);
5.6.3.  Set timer for powering off: When it’s powered on, press the “Timing” Button. As the “Timing Off” icon flickers and the time set flickers in relevant area, press “+” or “-” to adjust the timing. The dehumidifier makes a sound once the button is pressed. When the time set increases or decreases by “1”, holding the button constantly for 2s can continually increase or decrease the time. For non-action for 10s when it’s adjusted to the required value, the dehumidifier accepts the new setting and the “Timing Off” icon flickers (Ranging from 0H to 24H, and 0H as default);

6. TROUBLESHOOTING

6.1.   Upon fault of the dehumidifier, please cut off the power supply immediately, unplug the plug and check the following items:

power supply.
Check the plug plugged in properly.| Plug the power supply in the socket.
Check the fuse is not blown.| Replace the fuse.
Power Transformer is broken.| Replace the transformer.
Shown as power on| Environmental humidity lower than the set value.| Set again according to the demand.
If the water tank is installed correctly.| Place the water tank in right position.
If the entire machine is defrosting.| Wait for the completion of defrosting cycle.
Unfavourable dehumidifying effect| If the air inlet/outlet is obstructed.| Remove the obstacle.
If the door and window are open.| Close the door and window.
If the indoor temperature is too low.| Don’t run the dehumidifier.
Heavy noise| If the ground is firm and flat.| Resettle the dehumidifier.
Dehumidifier is stood precariously.| Resettle the dehumidifier.
Water leakage| Dehumidifier stood on an incline.| Move dehumidifier to a level surface.
Drain pipe/outlet obstructed.| Dismantle the front plate to eliminate blockage
E1| Coil sensor fault| Turn to timing for defrosting, to cancel system fault function.
E2/E3| Fault of humidity & temperature sensor.| Replace the humidity & temperature sensor.
EE| Refrigerant leakage.| Start the machine after. Ask for help from professionals if the “EE” signal remains.

6.2.     If the said methods still fail to eliminate the above problems, please directly contact the manufacturer or agents. DO NOT disassemble the dehumidifier, contact Sealey for repairs.
6.3.     It’s normal to hear the sound of the circulation of refrigerant when the dehumidifier runs.
6.4.   It’s normal for the air vent to blow warm air.
6.5.    INFORMATION FOR THE USER:
6.5.1. As a precision part, the humidity sensor may be damaged when used in environment filled with strong corrosive gas and heavy dust.
6.5.2.  As the dehumidifier is non-resistant against explosion, it’s forbidden to be used in environment of special requirements such as that filled with combustible/explosive gas, dust, chemicals or biological products.
6.5.3.  Damage caused to the dehumidifier by use in said environment will void the warranty.
6.5.4.  As water may be discharged from the machine after a certain amount of use, attention shall be paid to managing this water.
6.5.5. To minimize faults and maximize the lifetime, press the buttons gently.
6.5.6.  The deviation between the humidity shown on the sensor and the actual humidity is normal, due to impact by the location, environment and temperature.
6.5.7.  Since the cooled air is dried by the condenser before being discharged during operation of the dehumidifier, it’s normal for the air discharged to be hotter than the environment.
6.5.8. Since the dehumidifying effect is associated with the temperature and humidity of the environment, the higher the temperature and humidity of the environment, normally the greater the dehumidifying effect; while the lower the temperature and humidity of the environment, typically the lower the dehumidifying effect.
