| Install the base fixing plate if required, and tighten the two screws at the bottom/sides of the outer case.Install the front board.Install the air-return grids.Test running by connecting to power source, evaluating function and temperature controls and water drainage and confirm there are no abnormal sounds in operation. |  |
Cleaning & Care
- Before performing maintenance, ensure the air conditioner is turned off and the power plug has been removed from the socket.
- The air filter must be cleaned regularly to avoid dust buildup, which results in increased operational noise, lower overall efficiency and increased power consumption.
Before operational seasons
- Check to see if there are any objects blocking the air inlet and outlet of the indoor and outdoor units.
- Check to see if the installation base is corroded or rusty.
- Check the condition and function of the power point.
- Confirm the air filter screen.
- Connect to the power source.
- Load batteries into the remote control.

After operational seasons
- Set the temperature to 30°C and let the machine run for half a day in cooling mode to dry,
- Power off and unplug.
- Clean the air filter and reinstall.
- Clean both indoor and outdoor units.
- Remove batteries from remote controller.
During operational seasons
- Remove air filter screen by lifting gently, see image:
- Clean air filter screen in lukewarm water: do not use boiling water, dry with heat or pull with excessive force to avoid damaging it.
- Reinstall: DO NOT use air conditioner without air filter installed or performance degradation or failure may result
- Clean the air conditioner: use a soft, dry cloth or use a vacuum cleaner. A cloth soaked in gentle household detergent may be used if quite dirty.
Treatment of condensed water
| Method 1
Block the drainage hole on one side of the unit base with a rubber stopper to allow the condensed water to flow out of the rear drainage hole as per the image: • With this method, the water cannot be drained completely. The remaining water may improve the heat dispersion of the unit, but with some increased noise. • To install the drainage tube, install the sealing ring to the drainage tube and align the tube with the rear drainage hole of then unit. Then, turn the water outlet connecting tube 90° and clamp firmly. |
  |
| Method 2
The condensed water flows out the drainage hole on the base. • With this method, drainage is complete, which helps to prevent rust and avoids noise from water splashing. However, this requires installation at a sufficient height to allow the water containing plate to be placed between the base of the unit and supporting platform. • To install the plate, use a rubber stopper as per the image: |
