• Refrigerant Leakage Detect 
  Indoor unit shows error code "EC" and stops automatically when refrigerant leakage is detected. This protects the compressor from high temperature damage due to refrigerant leakage.
• Anti-cold Air Function 
  Indoor fan speed is regulated automatically from the lowest grade to the setting grade according to evaporator temperature when the unit just starts heating operation. This function can prevent cold air blowing out to avoid discomfort to the users.
• Emergency start
• Low Ambient Cooling 
  With built-in low ambient kit or special designed PCB, outdoor fan speeds can be changed automatically according to condensation temperature. The air conditioner can run heating operation even when the outdoor ambient temperature is down to -13°F.
• 1W Standby 
  Intelligent on-off technology enables Pioneer products automatically  enter energy-saving mode when standby, cut energy consumption from normal 5W to 1W or 0.5W per hour which counts 80%~90% of saving.
• 2-way Draining 
  Both left and right sides of the indoor unit are possible for outstretch of connective piping and drainage hose for easy installation.
• Follow Me (Remote Thermostat) 
  Temperature sensor built in the remote controller will sense it’s surrounding temperature. The unit will adjust the room temperature more accurately to give you comfort.
• 46°F Heating
  In heating operation, the preset temperature of the air conditioner can be as low as 46°F, which keeps the room temperature steady at 46°F and prevents the house from freezing when it is unoccupied for a long time in severe cold weather.
• Chassis Heating Belt
  Heating belt is fitted on the base plate of the outdoor unit to prevent defrosting water accumulation, which improves heat transfer efficiency.

Optional

• High Density Filter. Compared with ordinary dust filter, the anti-dust effect of this high density filter can increase more than 50%, it can clean dust, pollen up to 80%.

• Clean the Air Filters Regularly: To maintain optimal airflow and efficiency, clean the air filters every 1-2 months. Remove them from the unit and rinse with mild water or a vacuum to remove dust and debris. Allow them to dry thoroughly before reinstalling.

• Check for Ice or Frost: Inspect the evaporator coil for signs of ice buildup, especially during the summer months when the system is working harder. Ice buildup can hinder performance and may be a sign of airflow issues or low refrigerant. If you notice ice, turn off the unit and contact a professional for further inspection.

• Inspect and Clean the Coils: Over time, dust and dirt can accumulate on the evaporator and condenser coils, which may affect cooling and heating performance. Every 6 months, use a soft brush or compressed air to clean the coils. A dirty coil can lead to inefficiency and early wear on the system.

• Ensure Proper Drainage: Check the condensate drain regularly to prevent clogs that can cause water damage or poor cooling performance. Use a wet/dry vacuum to remove any debris or buildup from the drain line.

• Check Refrigerant Levels: If you experience reduced cooling or heating efficiency, it may be due to low refrigerant levels. Have a professional technician check refrigerant levels during annual maintenance to ensure the system is working at peak performance. Low refrigerant may indicate a leak that needs repair.

• Inspect Outdoor Unit: Clear any debris, leaves, or obstacles around the outdoor condenser unit to ensure it has enough space for proper airflow. Regularly inspect the unit for any visible signs of damage, wear, or dirt accumulation.

• Maintain the Refrigerant Lines: Check the insulation on refrigerant lines to ensure they are intact and free from damage. If the insulation is worn out or damaged, replace it to prevent energy loss and improve system efficiency.

• Monitor for Unusual Noises or Behavior: Pay attention to any unusual sounds, such as buzzing, rattling, or grinding, as these could be signs of a mechanical issue. Also, if the unit is not cooling or heating as expected, it might indicate a problem that requires professional attention.

• Schedule Professional Maintenance Annually: While regular DIY maintenance helps, professional servicing is essential for optimal performance and longevity. Have a certified technician inspect and clean the system yearly, checking refrigerant levels, inspecting components, and ensuring everything is functioning properly.
