• A bubbling sound may be heard when the refrigerant is circulating
through the compressor. Let the air conditioner operate in a selected
mode.
• When you press the Power button on the remote control, noise may be
heard from the drain pump inside the air conditioner.
• Check if the air conditioner has been cooling for an extended period of
time with the air flow blades pointed downwards. Condensation may
generate due to the difference in temperature.
• Check if your batteries are depleted.
• Make sure batteries are correctly installed.
• Make sure nothing is blocking your remote control sensor.
• Check that there are strong lighting apparatus near the air conditioner.
Strong light which comes from fluorescent bulbs or neon signs may
interrupt the electric waves.
• Check if you set the wired remote control for group control.
• Check if TEST indicator is displayed on the wired remote control. If so,
turn off the unit and switch off the circuit breaker. Call your nearest
contact center.
• Press the Power button on the remote control to turn the unit off and
switch the circuit breaker off. Then, switch it on again.
