Portable Air Conditioner Owner's Manual

1. BEFORE YOU BEGIN

1.1 PRODUCT DESCRIPTION

Powerful portable air conditioners are great cooling solutions for single rooms, creating a comfortable atmosphere. They also have ventilation and dehumidifying functions for circulating air and removal of moisture. These self-contained systems do not require permanent installation, allowing them to be moved to the space where they are most needed. They are commonly used in kitchens, temporary residences, computer rooms, garages, and many other places where installation of an Air-conditioner Outdoor Unit is limited.

The environmentally friendly R32 is used as the refrigerant. R32 has no damaging influence on the ozone layer (ODP), a negligible greenhouse effect (GWP), and is available worldwide. Because of its efficient energy properties, R32 is highly suitable as a coolant for this application. Special precautions must be taken into consideration due to the coolant's high flammability.

5.3.4 Automatic Defrost

At low room temperatures, frost may build up at 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 the cooling operation or drying operation, if 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, then the unit restarts to cool operating mode.
• B. When the unit operates in the drying operation, once the coil temperature sensor senses the temperature of the evaporator is below 104°F and the differential temperature between coil temperature and room temperature is below 66°F after the compressor operation 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, to protect the compressor, there is a 3-minute delay until the compressor restarts.

5.4 DRAINAGE

Manual drainage:

1. When the machine stops because the water is full, unplug the power plug. Please move the machine carefully to avoid spilling the water in the water pan at the bottom of the body.
2. Place a water container below the side water outlet behind the body.
3. Unplug the water plug; the water will automatically flow into the water 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 to the floor or carpet.
4. When the water is discharged, plug the water plug. Notes: Restart the machine after the water plug and drainage cover are installed; otherwise, condensate water will flow to the floor or carpet.

Continuous drainage:

The self-evaporating system uses the collected water to cool the condenser coils for better efficient performance. It is not necessary to empty the drainage tank in cooling operation, except in drying operation and high humidity conditions. The condensate water evaporates at the condenser and is evacuated through the exhaust hose.

For continuous operation or unattended operation in drying operation, connect the attached drain hose to the unit. Condensate water can flow automatically 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 and properly 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 that water can freely flow out of the unit.
• Do not submerge the end of the hose into water; otherwise, it can cause an "Air Lock" in the hose.

To avoid water spillage:

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

6. CLEANING AND CARE

6.1. CLEANING THE AIR FILTER (every two weeks)

Dust collects on the filter and restricts airflow. Restricted airflow reduces the efficiency of the system, and if it becomes blocked, it can cause damage to the unit.

The air filter requires regular cleaning. The air filter is removable for easy cleaning. Do not operate the unit without an air filter, or the evaporator may be 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 suck dust from the filter.
4. Turn the filter over and rinse the air filter under running water. Let the water run 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, which 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 let it into the eyes, on the skin, or clothing. Do not inhale vapors or gas.
6. Prevent it from entering sewers and public water areas.
7. Block the source of the release, if safe to do so. Consider the use of 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

Long-Term Storage: If you will not be using the unit for an extended period (more than a few weeks), it is best to clean the unit and dry it out completely. Please store the unit per the following steps:

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

ATTENTION: The evaporator inside the machine must 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 days to dry it out. Another way to dry the unit is to turn on the machine, adjust it to low-wind ventilation mode, and maintain this state until the drainage pipe becomes dry, so as to keep the inside of the body dry and prevent mildewing.

8.2. DISPOSAL

⚠ WARNING!!! Releasing refrigerant into the atmosphere is strictly forbidden!

Do not dispose of electrical appliances as unsorted municipal waste. Use separate collection facilities. Contact your local government for information regarding the collection systems available. If electrical appliances are disposed of in landfills or dumps, hazardous substances can leak into the groundwater and get into the food chain, damaging your health and well-being.
