4. Setup
Proper setup is crucial for efficient operation. Follow these steps to prepare your air conditioner for use:
4.1 Positioning the Unit
- Place the unit on a flat, stable surface.
- Ensure there is at least 50 cm of clear space around the unit for proper airflow.
- Position the unit near a window or opening for the exhaust hose.
4.2 Installing the Air Exhaust Hose
The exhaust hose expels hot air outside. There are two main installation options:

Image 4.1: Exhaust hose installation options.
- Option 1: Through a Window (Temporary)
- Attach the flexible hose adapter to one end of the air exhaust hose.
- Insert the other end of the hose into the air outlet on the back of the air conditioner.
- Open the window slightly and place the window outlet into the opening.
- Connect the flexible hose adapter to the window outlet.
- Close the window as much as possible to minimize air exchange with the outside. Consider using a window sealing kit (not included) for better efficiency.
- Option 2: Through a Window Bracket (Semi-Permanent)
- Assemble the window bracket according to the instructions provided with the bracket.
- Install the window bracket in a vertical or horizontal sliding window.
- Attach the flexible hose adapter to the air exhaust hose and then connect it to the opening in the window bracket.
- Ensure the connection is secure to prevent hot air from re-entering the room.
Important: The exhaust hose must be as short as possible and without sharp bends to ensure efficient operation. A minimum window opening width of 445 mm is required for the window bracket.

- Fan Mode (FAN): This mode circulates air without cooling or dehumidifying. You can select from 3 fan speeds.
5.3 Setting Temperature and Fan Speed
- Use the UP and DOWN arrows on the control panel or remote to adjust the desired temperature in Cooling mode.
- In Fan mode, press the FAN SPEED button to cycle through low, medium, and high settings.
5.4 EcoRealFeel Technology
The EcoRealFeel technology automatically optimizes temperature and humidity levels to achieve maximum comfort with reduced energy consumption. Activate this mode for intelligent and efficient climate control.

5.5 24-Hour Timer
The integrated 24-hour timer allows you to program the unit to turn on or off automatically. Refer to the detailed instructions in the full manual for setting the timer.
5.6 Silent Operation
For quieter operation, select the Silent mode. This reduces the fan speed and overall noise level, making it suitable for use during sleep or in quiet environments.
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your air conditioner.
6.1 Cleaning the Air Filter
- The air filter should be cleaned regularly (e.g., every two weeks) or more frequently depending on usage and air quality.
- Unplug the appliance from the power outlet.
- Locate and remove the air filter from the back or side of the unit.
- Wash the filter with lukewarm water and a mild detergent. Rinse thoroughly.
- Allow the filter to dry completely before reinserting it into the unit. Do not expose to direct sunlight.
6.2 Draining Condensate Water
During dehumidification or in very humid conditions, water will collect inside the unit. The PAC EX105 typically evaporates most condensate automatically. However, if the water tank becomes full, the unit will stop operating and display an error. You may need to manually drain the water:
- Unplug the appliance.
- Place a shallow pan or container under the drainage outlet (usually located at the bottom rear of the unit).
- Remove the drain plug and allow the water to flow out.
- Once drained, replace the drain plug securely.
6.3 Cleaning the Unit Exterior
- Wipe the exterior of the unit with a soft, damp cloth.
- Do not use abrasive cleaners, waxes, or solvents.
