At low room temperatures, frost may build up on the evaporator during operation. The unit will automatically start defrosting, and the POWER LED will blink. The defrost control sequence is as follows:

• A. When the unit operates in cooling and drying modes, and the ambient temperature sensor senses the evaporator coil temperature is below 30°F, the compressor will stop operating for 10 minutes or until the coil temperature reaches 44°F, after which the unit restarts in cool operating mode.
• B. When the unit operates in drying mode, if the coil temperature sensor senses the evaporator temperature is below 104°F and the differential temperature between coil temperature and room temperature is below 66°F after the compressor has operated for 20 minutes, the unit starts defrosting for 5 minutes, and the power indicator blinks.

5.3.5 Overload Protection

In the event of a power loss, there is a 3-minute delay to protect the compressor before it restarts.

5.4 DRAINAGE

Manual drainage:

1. When the machine stops because the water is full, unplug the power plug. Move the machine carefully to avoid spilling water from the pan at the bottom.
2. Place a water container below the side water outlet behind the body.
3. Unplug the water plug; water will automatically flow into the container.

Notes:

• Keep the water plug properly.
• During drainage, the body can be tilted slightly backward.
• If the water container cannot hold all the water, plug the water outlet as soon as possible before the container is full to prevent water from flowing onto the floor or carpet.
• When water is discharged, replace the water plug.

Notes: Replace the water plug and drainage cover before restarting the machine, otherwise condensate water will flow to the floor or carpet.

A diagram shows the rear of the unit with a drain hose connected to a bucket.

Continuous drainage

The self-evaporating system uses collected water to cool condenser coils for better efficiency. The drainage tank does not need emptying during cooling operation, except in drying operation and high humidity conditions. Condensate water evaporates at the condenser and is evacuated through the exhaust hose.

For continuous or unattended operation in drying mode, connect the attached drain hose to the unit. Condensate water can automatically flow into a bucket or drain by gravity.

• Switch off the unit before operating.
• Remove the plug of the water outlet opening and keep it in a safe area.
• Securely connect the drain hose, ensuring it is not kinked and is clear of obstruction.
• Place the outlet of the hose over a drain or bucket, ensuring water can flow freely out of the unit.
• Do not submerge the end of the hose into water, as this can cause an "Air Lock".

To avoid water spillage:

• As the negative pressure of the condensate drain pan is large, tilt the drain hose downward toward the floor. The inclination should exceed 20 degrees.
• Straighten the hose to avoid a trap.

6. CLEANING AND CARE

6.1. CLEANING THE AIR FILTER (every two weeks)

Dust collects on the filter and restricts airflow, reducing system efficiency. A blocked filter can cause damage to the unit.

The air filter requires regular cleaning and is removable for easy cleaning. Do not operate the unit without an air filter, as the evaporator may become contaminated.

1. Press POWER button to switch off the unit and unplug the power cord.
2. Remove the filter mesh from the unit.
3. Use a vacuum cleaner to remove dust from the filter.
4. Turn the filter over and rinse it under running water, allowing water to flow through the filter in the opposite direction of airflow. Set aside and allow the filter to air dry completely before reinstalling.

Switch off the unit and remove the air filters. Rinse the air filter under running water.

⚠ Warning!!! Do not touch the evaporator surface with bare hands, as it could cause injury to your fingers.

6.2. CLEANING UP OF REFRIGERANT

General Measures:

1. Gas/vapor is heavier than air and may accumulate in confined spaces, particularly at or below ground level.
2. Eliminate every possible source of ignition.
3. Use appropriate personal protection equipment (PPE).
4. Evacuate unnecessary personnel, isolate, and ventilate the area.
5. Do not get in eyes, on skin, or clothing. Do not breathe vapors or gas.
6. Prevent entry to sewers and public waters.
7. Stop the source of the release if safe to do so. Consider using water spray to disperse vapors.
8. Isolate the area until the gas has dispersed. Ventilate and gas test the area before entering. Contact competent authorities after a spill.

7. TROUBLESHOOTING

8. DECOMMISSIONING

8.1. STORAGE

For long-term storage (more than a few weeks), it is best to clean and dry the unit completely. Store the unit per the following steps:

1. Unplug the unit and remove the exhaust hose and window kit.
2. Drain any remaining water from the unit.
3. Clean the filter and let it dry completely in a shaded area.
4. Re-install the filter in its position.
5. The unit must be kept in an upright position when in storage.
6. Store the machine in a ventilating, dry, non-corrosive gas, and safe indoor place.

ATTENTION: The evaporator inside the machine must be dried out before packing to avoid component damage and mold. Unplug the unit and place it in a dry open area for days to dry. Alternatively, turn on the machine, adjust it to low-wind ventilation mode, and maintain this state until the drainage pipe becomes dry, to keep the inside dry and prevent mildew.
