11. Make sure that nothing is blocking the air inlet and outlet of the device

12. Use the device only on a level surface to prevent the condensation from spilling out

13. To provide additional protection, it is advisable to install a residual current device (RCD) in the electric circuit with a rated residual current not exceeding 30mA. Ask an electrician for this.

14. Clean the air filter regularly. The frequency of cleaning depends on the cleanliness of the air.

15. After turning off the machine, wait at least 5 minutes before turning it back on.

16. Do not use the device in sunny places. When the device overheats, the overheat protection will switch on the device.

17. To ensure effective cooling, a distance of at least 60 cm should be kept between the sidewalls of the device and the wall or furniture, or curtains.

18. Due to the limited performance of the device, if the difference between the target temperature and the ambient temperature is too great, the target temperature may not be reached.

19. To reduce the risk of fire, electric shock, or injury when using the air conditioner, observe the following basic precautions:
    a) Connect to a grounded outlet with 3 pins.
    b) Do not remove the grounding prong.
    c) Do not use the adapter.
    d) Do not use an extension cord.
    e) Disconnect the air conditioner before servicing.
    f) Use two or more people to move and install the air conditioner.

BEFORE FIRST USE – (picture E)
Connect the connectors to the air exhaust duct as follows:

1. Extend the air exhaust duct (9) by drawing out the two ends of the duct.
2. Screw the air exhaust duct (9) into the connector of the air exhaust duct (10).
3. Connect the connector of the air exhaust duct (11) to the device.

REMARKS:

1. Keep the unit at least 1 meter away from TV or radios to avoid electromagnetic interference.
2. Do not expose the unit under direct sunlight to avoid surface color fading.
3. Do not tilt the unit for more than 35°or upside-down while transporting. If the device has been turned over during transport, put it down correctly and wait 2-4 hours before starting it.
4. Place the unit on a flat surface with less than 5° inclination.
5. The unit operates more efficiently in certain room locations, select the best location:

– Beside a window, a door, or a French window.
– Keep the required distance from the return air outlet to the wall or other obstacles at least 60 cm.
– Extend the air exhaust duct (9) to ensure that another end of the air hose has a clearance between the window door, or French window, or wall hole.
– Air outlet or intake cannot be blocked by a protective grid or any obstacle.
To extend the life of the unit, drain the condensed water from the cooler drain port (8) before putting the unit into storage at the end of the season.
