2. Insert two new alkaline AAA batteries into the battery compartment, ensuring proper polarity.
3. Reattach the battery cover, making sure the locking tab clicks into place.

Note: Be sure to note proper polarity of batteries.

Battery Notes:

• Use alkaline batteries only. Do not use rechargeable batteries.
• When replacing batteries, always replace both batteries with new ones; do not mix old and new batteries.
• If the air conditioner will not be used for an extended period, remove the batteries from the remote control.

Remote Control Storage:

1. Insert the remote controller into the bracket in the back of the unit.
2. To avoid losing the remote control, please keep it stored when not in use.

Important Notes on Operation:

• The compressor will start approximately 3 minutes after the unit is turned on to prolong its life. After switching the unit off, wait at least 3 minutes before turning it back on.
• The compressor will switch off when the room temperature is lower than the set temperature. The fan will continue to work. When the ambient temperature rises above the set temperature, the cooling will resume.

Safety Protection Features:

1. Anti-frozen protection function: Under COOL mode, if the tube temperature is ≤36°F/2°C for 20 seconds after the compressor runs for over 10 minutes, the anti-frozen protection will activate. The LCD display will show 'E4', and the compressor and water wheel motor will stop working, while the upper fan continues running. If the tube temperature rises to ≥46°F/8°C, the unit will stop anti-frozen protection and recover to original working condition. The compressor will restart with a 3-minute delay for protection.
2. Auto Defrosting Operation: If the coil temperature is too low and humidity is too high, frost may form on the coils. The air conditioner will stop operation for 8-10 minutes for auto defrosting. Once the coils reach a temperature that prevents frost formation, the operation will recover automatically. Turn on your machine and wait for three minutes.
3. Water-Full Water Level Protection: This is performed by a water-level switch. The switch is always closed and opens only when an abnormal situation occurs in the water reservoir. When the reservoir is full, the switch moves, and the unit stops working. Please drain the water.

Installation Instructions

ATTENTION:

• a) Before you start, place the unit on a firm, level surface near a grounded 115V/60Hz power outlet. Only operate in an upright position.
• b) We recommend keeping the exhaust hose as short as possible to minimize heat loss back into the room.
• c) Ensure adequate space for air to flow around the unit, at least 50cm/19.7" from walls, curtains, draperies, or heat sources. Any blockage can lead to overheating of the air conditioner.
• d) The flexible exhaust hose can be extended from 10.63" to 59" for mounting. Keep the hose as short as possible to minimize heat loss back into the room.
• e) This hose length is designed according to the air conditioner's specifications. Do not use an extension or a different hose, as this may lead to malfunctioning.
• f) Handle with care to prevent any kinks or bends in the exhaust hose.

The unit is a portable air conditioner that can be moved from room to room.

Note: The window kit is designed for sliding windows or doors only and is not suitable for casement style windows.

Assemble the Outdoor Adaptor:

Align the two halves of the outer adaptor and gently snap them together. Note: To prevent damage, do not use excessive pressure.

Install the Outward Adaptor and Window Slide Bar:

1. Measure and verify if your window kit fits the dimensions of your sliding window. If the kit is larger than your window dimensions, it can be cut with a saw or power tool. If the kit is too short, you may order an additional window kit from the online store.
2. Screw the slide bar connector into the exhaust hose.
3. Spin the exhaust hose into the air outlet located at the rear of the unit (counter-clockwise).
4. Insert the slide bar connector into the adjustable slide bar.
5. Extend its length to match the width of the window (vertically or horizontally), and then tighten the screw to hold the length of the slide bar.
6. Ensure the adjustable slide bar fits your window securely and stays in place.
7. Close and lock your window on the slide Bar.

Or Install Directly Through a Wall/Window:

Cut a 150mm diameter hole in the wall or window, and feed the exhaust hose through the opening.

Drainage

1. Manual Drain:

This unit features a high-efficiency self-evaporative system where condensate is recycled. However, under extreme humidity, manual draining may be necessary. The portable air conditioner has an inner water reservoir with a safety micro switch. When the reservoir is full, the safety switch activates, and an alert icon turns on, indicating manual draining is required through the water hole on the back of the unit.

To manually drain the unit: Turn off the unit, place a pan or tray under the water hole, remove the plug and cap, and let the water drain. Once fully drained, replace the plug and turn the unit back on.

2. Continuous Drainage:

Unscrew the drain cover and unplug the water stopper. Connect a 12mm drain hose to the drain hole, ensuring it reaches as deep as possible to avoid leakage. Route the drain hose to a bathroom or outdoor drain.

Please note: The drain outlet must be at or below the level of the drain hose connection. NOTE: You need to purchase a 13mm PVC drain hose separately.

Maintenance

ATTENTION:

1. Before cleaning, turn the unit OFF and disconnect it from the electrical outlet.
2. Do not use gasoline or other chemicals to clean the unit.
3. Do not submerge the unit in water for cleaning.
4. Dry thoroughly before reassembling or storing.
5. Never operate the unit without the air filter installed.

Cleaning the Housing:

To clean the unit's surface, use a gentle detergent and a damp cloth, then wipe dry with a soft clean cloth. Avoid strong chemicals, oil-based products, detergents, or chemically treated cloths, as these can damage the housing.

Cleaning the Filter:

The air filter should be cleaned at least every 2 weeks to prevent clogging with dust and dirt. Open the air inlet grille on the back of the unit, remove the air filters, and clean them with a gentle detergent in lukewarm water. Allow the filters to dry completely, preferably in direct sunlight, before reinserting them into the unit.

Additional Maintenance and Tasks Prior to Storage:

• a. For seasonal storage, run the unit in Fan Mode for a couple of hours to ensure the interior is completely dry.
• b. Allow the unit to air dry for 24 hours with the drain plug and cap removed.
• c. Clean or change the air filter.
• d. Store the power cord and protect the unit from dust by placing it back in its original box.
