    Outdoor Unit

    NOTE
    Dirty or clogged coils will reduce the operating efficiency of the system and cause higher operating costs.

    Operation Tips!
    Do not overcool the room.
    This is not good for the health and
    wastes electricity.

    Make sure that the
    doors and windows
    are shut tight.
    Avoid opening doors and
    windows as much as
    possible to keep the cool
    air in the room.

    Keep blinds or curtains
    closed.
    Do not let direct sunshine enter
    the room when the air conditioner
    is in operation.

    Clean the air filter
    regularly.
    Blockages in the air filter
    reduce the airflow and lower
    cooling and dehumidifying
    effects. Clean at least once
    every two weeks.

    Keep the room temperature
    uniform.
    Adjust the vertical and horizontal
    airflow direction to ensure a
    uniform temperature in the room.

    Ventilate the room
    occasionally.

    Use high fan speed
    for effective and fast
    cooling.

    Since windows are kept
    closed, it is a good idea to
    open them and ventilate
    the room now and ten.

    The unit gives its rated
    cooling capacity when the
    fan speed is high.

    Avoid spilling water or milk at the top of the
    indoor unit.

    Be cautious when your children are opening the
    inlet Grille Because it is locked by magnetic type.

    It may cause product failure.
