Before First Use

Please leave the dehumidifier sitting outside the box for 24 HOURS before plugging it in. This is because the dehumidifier may have been tilted or placed upside down during shipping. Allowing it to sit for 24 hours lets the oil in the compressor settle, which is crucial for performance and lifespan.

Instructions For Repairing Appliances Containing R32

General Instructions

• Before working on systems with flammable refrigerants, perform safety checks to minimize ignition risk.
• Ensure the work area is open or adequately ventilated before breaking into the system or conducting hot work. Ventilation should continue during work to disperse any released refrigerant.

Detection of Flammable Refrigerants

• Never use potential sources of ignition when searching for or detecting refrigerant leaks. Halide torches or detectors using naked flames are prohibited.
• Acceptable leak detection methods include:
• Electronic leak detectors: Sensitivity may need adjustment or re-calibration for flammable refrigerants. Ensure the detector is not an ignition source and is suitable for the refrigerant. Calibrate to a percentage of the LFL (Lower Flammable Limit) of the refrigerant.
• Leak detection fluids: Suitable for most refrigerants, but avoid those containing chlorine, as it can react with the refrigerant and corrode copper pipework. Examples include bubble method and fluorescent method agents.
• If a leak is suspected, extinguish all naked flames. If brazing is required for a leak, recover all refrigerant or isolate the system remotely.

Machine Structure Diagram

Diagram Description:

The dehumidifier has the following components:

• Top View: Control panel, Air inlet, Air outlet, Wind out, Casters. A magnified view shows the Electrical control box.
• Side View: Power cord box, Gravity Drainage outlet, Pump Drain Outlet.

Note: There may be slight differences in the model; the actual machine shall prevail.

Operation Instruction

Operation Panel

The operation panel includes:

• Indicator lights: Timer light, Full light, Defrosting light, Power light.
• Control buttons: TIMER, UP, DOWN, POWER.
• Display window.

Key Description:

1. Power switch key: Press once to turn on/off the machine.
2. Up key: Increases the humidity setting value.
3. Down key: Decreases the humidity setting value.
4. Timer key: Used to set the timing time.

Humidity Setting:

In power-on state, press "Up" or "Down" to enter humidity setting mode (display flashes humidity value). Adjust humidity between 10-98% RH. The setting state exits automatically after a few seconds of inactivity.

Timer Setting:

In power-off state, set for timed power-on. In power-on state, set for timed power-off. Press the "Timer key" to set timer time (1-24h, increments of 1h). Press and hold to adjust continuously. If timer time is 00, it is invalid. The timer indicator lights up when the timer is valid. Pressing the "Timer key" again displays the remaining timer time.

Action Description:

• Startup: Fan turns on, compressor starts with a delay.
• Shutdown: Compressor stops immediately, fan stops after a delay.
• The compressor can be turned on again 3 minutes after stopping without turning off the power supply.

Defrosting Function:

At low ambient temperatures, the system automatically detects frost and defrosts. During defrosting, the fan continues, but the compressor stops. The defrosting indicator is on during defrosting and off when it ends.

Fault Code:

Note: Fault code existence depends on the actual model's function.

Notice:

1. If EC fails, the operation panel buttons are unresponsive. Check connection wires between the display board and main control board for looseness or poor contact. Re-tighten if loose, or contact a professional for loose terminals/broken wires.
2. When the "FULL" indicator is on, the machine stops working. Contact a professional. If immediate use is needed, open the electric control box, pull the plug at the "WF" position of the main control board, and open the natural drainage port to connect a water pipe.

* Dealing with the above problems requires power off.

Temperature Protection Function

1. If ambient temperature is higher than the high temperature setting (default 113°F / 45°C), the system enters high temperature protection, prompts "HH", and the compressor stops.
2. If ambient temperature is lower than the low temperature setting (default 39°F / 4°C), the system enters low temperature protection, prompts "LL", and the dehumidifier stops.

State Description:

1. Power On: Fan starts, compressor starts after a delay.
2. Power Off: Compressor stops immediately, fan stops after a delay.
3. To prevent frequent starting/stopping, there is a 3-minute delay in the start-up interval.

Turn The Dehumidifier Off:

Press the Power Switch to turn the dehumidifier off. To protect the compressor, the fan will continue to operate for 5 seconds after shutoff. Do not disconnect the power cord to force a stop; always use the power button.

Maintenance

Unplug the power cord before maintaining and cleaning. Use a soft damp cloth to clean the body. Do not use detergents, scrubbing wires, chemically treated cloths, gasoline, thinner, or other solvents.

Clean the filter:

The dehumidifier has a washable filter for airborne dirt. Check and clean it at least once a month.

1. Use a vacuum cleaner to gently remove dirt from the filter.
2. If the filter is very dirty, rinse it with warm water and mild detergent, then dry thoroughly. Do not expose to direct sunlight or use exothermic products for drying, as this can deform the filter and frame.
3. Put the dried filter back into the dehumidifier. If the dehumidifier fails, follow the "Troubleshooting" section before contacting ANDTE support. Do not attempt to repair or disassemble the unit yourself.

Improper maintenance may endanger user safety.

Note: Do not operate the dehumidifier without a filter, as dirt and lint can clog it.
