6. Advanced Features
The HPG-ET18K2CH19S model incorporates several features designed for enhanced performance, efficiency, and user comfort.
- Smart Pan Heater: Prevents ice formation in the base pan of the outdoor unit, ensuring efficient operation in cold climates.
- Compressor Blanket and Preheating Technology: Keeps the oil inside the compressor warm, preventing it from mixing with the refrigerant and improving system longevity and efficiency.
- Anti-Corrosion Fin Coating: Both condenser and evaporator fins are covered with a hydrophilic coating, providing enhanced corrosion resistance, particularly beneficial in coastal environments.
- Refrigerant Leakage Detection: The indoor unit displays 'EC' if the outdoor unit detects refrigerant leakage, prompting immediate attention.
- Smart Defrosting: Optimizes defrost cycles to provide greater comfort and energy savings by eliminating unnecessary defrost operations.
- Smart Preheating: In heating mode, the system delays fan activation at startup to prevent cold air from being blown into the room.
- Auto Restart: In the event of a power failure, the system stores user selections and parameters in non-volatile memory and automatically resumes the last operating mode when power is restored.
- Auto-Clean: This function helps keep the indoor unit dry, reducing the potential for mold and mildew growth.
- Self-Diagnosis: A microcomputer continuously monitors the system. If abnormal operation is detected, the unit will shut down, and an error code will be displayed on the indoor unit to assist with maintenance.
- Turbo Mode: Activates super high-speed operation for rapid cooling or heating of the room.
- Up & Down Swing: Allows selection of oscillating angles for the vertical louvers to direct airflow.
- Timer: Enables programming the unit to start and stop automatically over a 24-hour period.
- Sleep Mode: Gradually adjusts the room temperature during sleep to maintain comfort and save energy.
- Silence Function: Operates the unit at a low frequency and the fan at its lowest speed to minimize noise levels.
7. Maintenance
Regular maintenance ensures optimal performance and longevity of your heat pump system. Always disconnect power before cleaning or servicing.
7.1 Indoor Unit
- Air Filters: The indoor unit features washable filters. Clean these filters every two weeks or more frequently depending on usage and air quality. Remove filters, wash with lukewarm water and mild detergent, rinse thoroughly, and allow to dry completely before reinserting.
