Maintaining your Unit

1. Clean indoor unit’s air filter 1x month
Save energy by preventing indoor coils from being plugged with dirt and lint. To remove the filter, gently push forward on the handle tabs, then lift the filter out of place. Rinse or vacuum - do not scrub filter with a brush or place in the dishwasher. Damage will occur.
2. Auto clean function, indoor unit
Under unit OFF status, hold “MODE” and “FAN” buttons simultaneously for 5s to turn Auto Cleaning on or off. When Auto Clean is on the indoor unit displays “CL” and the unit will heat up and cool quickly. You may hear the sound of flowing liquid or thermal expansion or contraction. Make sure the room is well ventilated at this time as the unit may blow cool or warm air, this is normal.
3. ** To keep your unit in top operating condition, have it serviced by an HVAC professional every 6 months.


If you are experience a problem with your system, please check the items below. If the issue cannot be resolved, please contact a local qualified HVAC technician for service.

To maintain consistent temperatures and minimize energy-loss from constant starts & stops, the fan keeps air flowing past the sensor.
The remote always displays your desired indoor temperature. (You may view current indoor and outdoor temperatures, as well as desired temperature, on the indoor unit’s Front Panel Display.)
Lift the front panel section on the indoor unit and locate the AUX button on the right-hand side. Press the button to turn the unit ON or OFF. (Not all functions will be available.) Press again to cancel AUX Mode and transfer control back to the remote.
Turn the unit OFF, then press "▼" and "MODE" buttons on the remote simultaneously to switch between °C and °F.
This means you have a “mode” conflict in your multi-zone system. Make sure all your indoor units are in the same mode (cooling or heating).
  • Remove interference from static electricity by disconnecting the power at the breaker for 3 minutes.
  • Move the remote within the signal receiving range of 26 feet.
  • Remove any obstacles so the remote has a clear path to the indoor unit receiver.
  • Point the remote at the receiving window on the indoor unit.
  • Check and replace the batteries if the sensitivity of the controller is low; fuzzy display or no display.
  • Check that the remote controller is not damaged. If yes, replace it.
  • Prevent electronic interference by moving the remote controller closer to the indoor unit and turning off other electronics.
  • Eliminate obstacles that could be blocking the air inlet or air outlet of indoor unit.
  • If during HEAT mode, the fan is designed to turn itself off when the indoor temperature is reached. This is normal.
  • If during the initial start of HEAT mode, in order to prevent cold air from blowing out it may take several minutes before the fan starts. This is normal.
  • Experiencing a power failure? Wait until power recovery.
  • Discovered loose wiring? Contact a contractor or an electrician.
  • Has a circuit breaker tripped or a fuse burnt out? Hire a professional to replace the circuit breaker or fuse.
  • Is wiring overheating or needs repair? Hire a professional to replace it.
  • Unit has restarted immediately after stopping operation? Turn the unit off, wait 3 minutes then turn it back on.
  • Does the remote controller show the correct setting? Reset the function.
Is the indoor temperature and humidity high? Mist will occur when the indoor air is cooled rapidly. After a while, indoor temperature and humidity will be decrease and mist will disappear.
Check for the source of the odor and eliminate the odor; rugs, furniture, cigarettes, etc. Clean the filter.
Does your required temperature exceed the set temperature range? Set temperature range: 16°C-30°C (61°F-86°F)
  • Check if the voltage is too low. If too low, call an HVAC technician.
  • Check if the filter is dirty. If dirty, clean the filter.
  • Check that the temperature is set to the proper range.
  • Close doors or windows that shouldn't be open.
Disconnect the power, put back power, and then turn on the unit again if there are interferences; lighting, wireless devices, etc.
This is normal if the unit has just been turned on or off. The noise is the sound of refrigerant flowing inside the unit, which is normal.
This is normal if the unit has just been turned on or off. This is the sound of friction caused by expansion and/or contraction of panel or other parts due to temperature changes.
Disconnect the power for 3 seconds and then connect the power; if the problem still exists, call an HVAC technician to resolve.
