Portable Air Conditioner Owner's Manual

1. Before You Begin

1.1 Product Description

Portable air conditioners offer effective cooling for single rooms, creating a comfortable indoor environment. These units also provide ventilation and dehumidification by circulating air and removing moisture. As self-contained systems, they do not require permanent installation, allowing for flexible placement where cooling is most needed. They are commonly used in kitchens, temporary residences, computer rooms, garages, and other locations where the installation of an outdoor air conditioner unit is impractical or limited.

2. For Your Safety

2.2 Safety Precautions on Servicing

2.2.1 Checks to the area

Before working on systems containing flammable refrigerants, safety checks are essential to minimize ignition risks. For refrigeration system repairs, the following precautions must be observed:

2.2.2 Work procedure

Work must be undertaken under controlled procedures to minimize the presence of flammable gas or vapor during performance.

2.2.3 General work area

All maintenance staff and others in the local area must be informed about the nature of the work. Confined spaces should be avoided. The work area must be sectioned off, and conditions within the area made safe by controlling flammable materials.

2.2.4 Checking for presence of refrigerant

The area must be checked with an appropriate refrigerant detector before and during work to ensure technicians are aware of potentially flammable atmospheres. Leak detection equipment used must be suitable for flammable refrigerants (e.g., non-sparking, adequately sealed, or intrinsically safe).

2.2.5 Presence of fire extinguisher

If any hot work is to be conducted on refrigeration equipment or associated parts, appropriate fire extinguishing equipment must be readily available. A dry powder or CO2 fire extinguisher should be adjacent to the charging area.

2.2.6 No ignition sources

No person performing work on a refrigeration system that involves exposing pipework containing or having contained flammable refrigerant shall use any ignition sources that could lead to fire or explosion. All possible ignition sources, including cigarette smoking, must be kept sufficiently far from the installation, repair, removal, and disposal site, where flammable refrigerant could be released. Before work begins, the area around the equipment must be surveyed for flammable hazards or ignition risks. "No Smoking" signs must be displayed.

2.2.7 Ventilated area

Ensure the area is open or adequately ventilated before breaking into the system or conducting any hot work. Ventilation must continue throughout the work period to safely disperse any released refrigerant, preferably expelling it externally into the atmosphere.

2.2.8 Checks to the refrigeration equipment

When electrical components are replaced, they must be fit for purpose and meet correct specifications. Manufacturer's maintenance and service guidelines must always be followed. If in doubt, consult the manufacturer's technical department. The following checks apply to installations using flammable refrigerants:

• The charge size must comply with the room size where refrigerant-containing parts are installed.
• Ventilation machinery and outlets must operate adequately and not be obstructed.
• If an indirect refrigerating circuit is used, the secondary circuit must be checked for refrigerant presence.
• Equipment markings must remain visible and legible; illegible markings and signs must be corrected.
• Refrigeration pipes or components must be installed where they are unlikely to be exposed to substances that may corrode refrigerant-containing components, unless constructed of inherently resistant materials or suitably protected.

2.2.9 Checks to electrical devices

Repair and maintenance of electrical components must include initial safety checks and component inspection procedures. If a fault compromises safety, no electrical supply should be connected until the circuit is satisfactorily dealt with. If immediate correction is not possible but operation must continue, an adequate temporary solution must be used and reported to the equipment owner. Initial safety checks include:

• Discharging capacitors safely to avoid sparking.
• Ensuring no live electrical components or wiring are exposed during charging, recovering, or purging the system.
• Verifying continuity of earth bonding.

4.3 Attach the Exhaust Hose

The air conditioner requires external venting to allow waste heat and moisture to escape the room. Do not replace or extend the exhaust hose, as this will decrease efficiency and may cause the unit to shut down due to low backpressure.

1. Step 1: Connect the hose connector to one end of the exhaust hose. (Depiction: A corrugated hose with a circular connector attached to one end.)
2. Step 2: Connect the window kit adapter to the other end of the exhaust hose. (Depiction: A corrugated hose with a rectangular window kit adapter attached to the other end.)
3. Step 3: Fix the window seal set on the windows. Part A is the sealing material, and Part B is velcro. Refer to the window seal manual for detailed steps. (Depiction: A fabric window seal with velcro strips, labeled A and B, designed to fit around a window opening.)
4. Step 4: Close your window to secure the kit in place. The window kit needs to be held firmly; secure it with duct tape if necessary. It is recommended that the gap between the adapter and the sides of the window be sealed off for maximum efficiency. (Depiction: A window with the exhaust hose and window kit installed, showing the hose extending outdoors.)
5. Step 5: Attach the hose connector to the exhaust air outlet of the unit. (Depiction: A portable air conditioner unit with the exhaust hose connected to its rear outlet.)
6. Step 7: Adjust the length of the flexible exhaust hose, avoiding bends. Place the AC unit near an electrical outlet.
7. Step 8: Adjust the louver at the air outlet, then switch on the unit. (Depiction: A portable air conditioner unit with the exhaust hose connected and extending out a window, ready for operation.)

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:

1. When the unit operates in cooling or drying mode, if the ambient temperature sensor detects the evaporator coil temperature is below -1°C, the compressor will stop for 10 minutes or until the coil temperature reaches 7°C, then the unit restarts in cool operating mode.
2. When the unit operates in heating or drying mode, if the coil temperature sensor detects the evaporator temperature is below 40°C and the differential temperature between coil temperature and room temperature is below 19°C after 20 minutes of compressor operation, 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 before the compressor restarts to protect it.

5.4 Drainage

Manual drainage:

1. When the machine stops because the water tank is full, unplug the power plug.

Notes: Move the machine carefully to avoid spilling water from 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; water will automatically flow into the container.

Notes:

1. Keep the water plug properly.
2. During drainage, the body can be tilted slightly backwards.
3. If the water container cannot hold all the water, stuff the water outlet with the water plug as soon as possible before the container is full to prevent water from flowing onto the floor or carpet.

4. When the water is discharged, re-insert the water plug.

Notes: Restart the machine after the water plug and drainage cover are installed; otherwise, condensate water will flow onto the floor or carpet. (Depiction: A portable air conditioner unit with a drainage hose connected to its lower rear outlet, leading into a bucket on the floor.)

Continuous drainage

The self-evaporating system uses collected water to cool the condenser coils for better efficiency. It is not necessary to empty the drainage tank 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 and properly connect the drain hose, ensuring it is not kinked and clear of obstruction.
• Place the outlet of the hose over a drain or bucket, ensuring water can flow freely from the unit.
• Do not submerge the end of the hose into water; doing so can cause "Air Lock" in the hose.

To avoid water spillage:

• Due to the negative pressure of the condensate drain pan, tilt the drain hose downward toward the floor. An inclination exceeding 20 degrees is appropriate.
• Straighten the hose to avoid any traps.

6. Cleaning and Care

6.1. Cleaning the Air Filter (every two weeks)

Dust accumulation on the filter restricts airflow, reducing system efficiency and potentially damaging the unit if blocked. The air filter requires regular cleaning and is removable for easy maintenance. Do not operate the unit without an air filter, as the evaporator may become contaminated.

1. Press the 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. Allow water to run through the filter in the opposite direction of airflow. Set aside and allow the filter to air dry completely before reinstalling.

A diagram shows a hand holding an air filter under a running faucet, illustrating the rinsing process.

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

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. Avoid contact with eyes, 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 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 the unit will not be used for an extended period (more than a few weeks), it is best to clean and dry it completely. Store the unit following these steps:

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

8.2. Disposal

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