Symptoms: Green light is flashing, fan is running but there is no cooling, and compressor does not start.
Explanation: Thermostat setting is higher than room temperature or function is set to “ventilate” instead of “snowflake”. Below 18°C, the compressor will not start because the room is too cold and there is a risk that ice would form inside and damage your air conditioner.
Cure: Press FUNC to make the snowflake symbol appear (bottom left corner) and lower the thermostat temperature.
Symptoms: Air conditioner does not start, green light flashes 6 times, then pauses and repeats.
Explanation: Software needs a reset.
Cure: Disconnect the power – either switch off the power point, or disconnect the power lead for 5 minutes.
Avoiding the problem: When you have finished using your Close Comfort AC, switch it off with the remote control before closing the warm air cover. Even better, leave the warm air cover open unless you don’t plan to use Close Comfort for several days.
Symptoms: the room seems to get noticeably warmer with Close Comfort running.
Explanation: in a well-insulated small room with doors and windows closed, the room temperature can increase slightly, just as it would with two or three people in the room. Close Comfort does emit about the same heat as three people. However, as you become used to the cool microclimate that Close Comfort provides for you, the other parts of the room will seem to be warmer even if there is no measurable temperature change.
Cures: keep a door or window open – this is a healthy option in any case. Unlike normal room air conditioners, Close Comfort works just as well with open doors and windows and fresh air circulating.
If you cannot keep a door open and you like the curtains fully closed to keep out the light, consider the following solution from one of our customers. He placed his air conditioner about 15 cm from the wall beneath an open window and draped the curtain over the middle so the warmer air went straight out of the window. In the first photograph, the curtain is drawn. The other photograph taken with the curtain drawn aside shows the air conditioner position relative to the window.
If you only have short curtains, elevate your air conditioner on a small table.
Symptoms 1: The noise from the AC seems loud and some users find it annoying.
Explanation: On high fan speed, the AC noise is about 54 dB at a distance of 1 metre, about the same as an electric fan at high speed. It is much quieter at the medium and low fan speeds.
Cure: For sleeping, place the AC unit about 15 cm from the end of the bed as shown in the instruction guide. The bedding will absorb much of the noise.
Run the AC on medium speed. If you need faster air flow, use the Cool Focus accessory which increases the air flow speed up to three times. With the windows open, the AC needs to provide just enough noise to mask noises coming from outside to promote sound sleep.
Symptoms 2: A rushing water sound comes from the back of the AC.
Explanation: In humid weather conditions, water is condensed on the air cooling coils at the front of the machine and passes to the back side where the water is sprayed onto the warm condenser coils. The noise is caused by the water spray. The water enables the AC to increase the cooling power by up to 50% or more, with no increase in electricity consumption. This is what make Close Comfort particularly effective in humid weather conditions. The noise level does increase slightly.
Cure: If you really don’t want to hear the water rushing sound, you can remove the rubber bung just above the power cord storage drawer at the back of the AC. This will reduce the cooling power in humid weather: it will not perform at the specified level. Also, after 2 – 5 hours, the AC will switch off automatically when the drawer is full of water. Then you need to empty out the water before using it again. Take care not to spill the water as you remove the drawer!
Symptoms: Water leaks from air conditioner
Explanation: The air conditioner should not leak at all. However, if it is not upright, even if tilted at a slight angle, water can leak from the cold evaporator onto the floor. This can happen if the AC is placed on a chair, for example. The seat on most chairs is not flat.
Cure: Make sure the air conditioner is placed on a hard, flat, level surface.
Symptoms: Air conditioner loses its cooling effect intermittently
Explanation: Drafts and nearby fans can disrupt the cool air flow from your Close Comfort AC, reducing the cooling effect for users.
Cure: Use Close Comfort in a draft free location.
Symptoms: Air conditioner loses its cooling effect gradually over time
Explanation: Household dust accumulating on the three air filters can gradually reduce the air flow, reducing the apparent cooling.
Cure: We recommend you inspect at least the cool air inlet filter at the front of the AC unit every two weeks. Once there is a noticeable amount of dust, clean all three filters by rinsing them under a tap.
We also recommend that you ask an air conditioning technician to clean the inside of your AC annually, especially in very dusty locations.
