Hold the top of the air outlet window in the front panel with one hand and the handle at the top of the back panel with the other hand. Move the unit in an upright position.

Note:

• Do not hold the horizontal louvers by hand.
• Keep the unit in an upright position when handling or moving it.

Drain the water in the unit completely to prevent water leakage and wet the floor or carpet before handling or moving the unit.

Take away the remote control before handling or moving the unit.

Diagrams illustrate the correct handling positions.

Installation & Adjustment

1. Installation

Warning:

• Keep this mobile air-conditioner in an upright position for at least 2 hours before first installation.
• This air-conditioner can be moved indoors conveniently; keep the unit in an upright position while moving it. The air-conditioner shall be placed on a flat surface.
• Do not install or operate this air-conditioner in a bathroom or other wet environments.

1.1 Installation of exhaust hose assembly and its adapter

1. Take out the exhaust hose assembly and its adapter from the plastic bag.
2. Extend the exhaust hose at one end and screw the round end of the adapter into the exhaust hose counterclockwise.
3. Note: Screw the adapter into the correct position, at least 3 turns, to ensure a good connection.

1.2 Installation of the exhaust hose assembly into unit

1. Determine the window seal-plate position: vertical or horizontal.
2. If the window seal-plate is horizontal, the slant panel A of the adapter should be upwards.
3. If the window seal-plate is vertical and on the left side of the window, the slant panel A of the adapter should be to the right.
4. If the window seal-plate is vertical and on the right side of the window, the slant panel A of the adapter should be to the left.

Diagrams show how to connect the exhaust hose assembly to the unit.

1.3 Installation of window seal-plate

1. Open the window in half and place the seal-plate into the window, determining its vertical or horizontal position according to the window opening direction.
2. Extend the seal plate parts, adjust them to the window length, and fix them with screws.

Remarks:

• Ensure the two ends of the window seal-plate meet the window edges properly for a good seal.
• Fix the screws in the correct position.

1.4 Installation of the unit

1. Move the unit with its exhaust hose assembly in front of the window, keeping the unit at least 50cm away from walls or other objects.
2. Install the rectangular end of the exhaust hose adapter into the corresponding rectangular hole in the window seal-plate assembly, fix it with a screw, and close the window.
3. Align the 4 openings on the window seal-plate with the 4 openings on the exhaust hose adapter. Set them together, then slide the adapter downwards to lock the two parts securely.
4. Secure with a self-tapping screw (ø4mm) into the adapter hole.

Remarks:

• Slide the adapter downwards and ensure it is installed correctly.
• Tighten the screw to prevent it from falling off.
• The exhaust hose should not be bent or flexed more than 45° to ensure proper ventilation.

Important notes:

The exhaust hose is 280mm-1500mm long. Do not use a prolonged or different hose, as this may affect the air conditioner's functions. An obstructed exhaust hose can lead to overheating and tripping of the air conditioner.

Drainage Instruction

1. Manual drain:

When the water tank reaches its alarm level, warning sounds will activate, and the unit will stop working. The water-full indicator and "FL" will flash on the LED display.

1. Place a tray below the water outlet at the back of the unit.
2. Unscrew the drain cover and unplug the water stopper to allow water to flow into the tray.
3. Plug in the stopper and screw the water cover tightly onto the water outlet after drainage.

Notes:

• Protect the drain cover and water stopper.
• Move the unit carefully to avoid leakage if necessary.
• Tilt the unit slightly backwards when draining.
• Block the drain hole as soon as possible if the tray is full to prevent water leakage onto the floor or carpet.
• Ensure the water stopper and drain cover are tightly installed to prevent condensate from wetting the floor or carpet when the unit restarts.

Diagrams show the drain cover, water stopper, and drain hole.

2. Continuous drain:

1. Unscrew the drain cover and unplug the water stopper.
2. Connect a ø13mm PVC drain hose to the drain hole, ensuring a snug fit to prevent leakage.
3. Route the drain hose to a bathroom or outdoor drain.

Notes:

• The drain hose must be installed before the unit starts working.
• It is suggested to use manual drainage during cooling mode to ensure sufficient water for recycling, which aids condenser cooling and improves performance.
• Place the drain hose in an inaccessible location, ensuring it is not higher than the drain hole and remains straight without any kinks.
• Keep the drain cover and its stopper properly installed when continuous drainage is used.

Diagrams show the water stopper, drain hole, and drain cap.

Maintenance and Service

Remark: Turn off the unit and unplug it before performing any maintenance or sending it for service.

1. Surface cleaning

Clean the unit surface with a soft, damp cloth. Do not use chemical solvents like alcohol or gasoline, as they can damage the unit.

2. Filter cleaning

Clean the filter every two weeks. A clogged filter can reduce the unit's performance.

2.1 How to clean filter:

1. Grip the filter handle and gently pull it out in the direction shown by the arrow.
2. Notes: Use even force to remove the filter to avoid twisting or damage. Remove filters from the back panel first, then the side panel.
3. Clean the filters gently in warm water (around 40°C) mixed with detergent, and dry them in the shade.
4. Notes: Do not squash the mesh. Do not use sharp objects or brushes on the mesh.

2.2 Installation of the filter:

Special note: Install the filters to the side panel first, then the filter into the back panel.

1. Align the filter end with the slot and gently push the filter into the slot.
2. Notes: Install the filter in the opposite direction of removal. Install the filter gently to avoid damage.

3. Cleaning of handle position and remote control storage area:

1. Take out the remote control.
2. Clean the handle position and remote control storage area with a wet and soft cloth.

Note: Do not drip water into the unit.

End of Season Storage

1. Unscrew the drain cover and pull out the stopper to drain water completely. (Note: The tilt angle of the unit must be ≤ 30°).
2. Run the unit in fan mode for half a day to dry the interior completely and prevent mold.
3. Turn off the unit, unplug it, wrap the power cord around the wire-winding pillar, insert the plug into the universal fixing hole at the back panel, and install the water plug and drain cap.
4. Remove the heat exhaust hose assembly, clean it, and keep it properly.

Notes:

• Hold the exhaust hose assembly with both hands when removing it.
• Push the fasteners aside on the exhaust air outlet with your thumbs, then pull out the exhaust hose assembly.
• Pack the air-conditioner properly with a soft plastic bag and store it in a dry place with appropriate dust-proof measures. Keep the unit away from children.
• Remove the batteries from the remote control and keep them properly.

Note: Ensure the unit is stored in a dry place. All accessories should be protected together.

Troubleshooting

Check the unit and suggestions below before seeking professional service. Never dismantle or repair the unit yourself, as it may cause harm to you and your property.
