Usage Features:
- Remote Controller: The manual assumes a BRC1C62 remote controller (though BRC1E51A is also mentioned). It features an on/off button, operation lamp, display for changeover control, air flow flap, ventilation/air cleaning, set temperature, operation mode, programmed time, inspection/test operation, centralized control indicator, fan speed, air filter cleaning reminder, defrost/hot start indicator, timer mode start/stop, timer on/off, programming time, temperature setting, filter sign reset, fan speed control, operation mode selector, and air flow direction adjust buttons.
- Operation Modes: Cooling, heating, automatic, fan only, and program dry.
- Temperature Adjustment: Set desired temperature using the temperature setting button, adjustable in 1°C increments.
- Fan Speed Control: Select preferred fan speed using the fan speed control button.
- Air Flow Direction: Adjustable via the air flow direction adjust button, offering automatic swing or fixed positions.
- Timer Operation: Program start and stop times up to 72 hours in advance.
- Hot Start/Defrost Operation: Automatic functions to prevent cold air blowing during heating startup and to defrost the outdoor unit when ice builds up, indicated by specific symbols on the remote controller.
- Safety Features: Automatic restart after power failure, compressor protection (5-minute delay before restarting), and automatic fan stop during defrost.
- Group Control System: One remote controller can manage up to 16 indoor units simultaneously.
- Two Remote Controller Control System: Two remote controllers can control one indoor unit (or one group of indoor units) individually.
Maintenance Features:
- Regular Cleaning:
- Outdoor Unit: Consult local dealer.
- Indoor Unit: Stop operation with remote controller and cut off power breaker before cleaning. Refer to the indoor unit manual for details.
- Showcase and Unit Cooler: Refer to their respective operation manuals.
- Drain Pan (Optional Accessory): Clean to prevent clogging and dust.
- Air Filter Cleaning: The remote controller displays a reminder when the air filter needs cleaning. A qualified service person should perform this.
- Power Off for Long Periods: Turn off the main power supply switch if the unit is not used for a long time to prevent dust accumulation, heat generation, or ignition.
- Pre-operation Power On: Turn on the main power switch 6 hours before resuming operation after a long period of being off to ensure smooth running and machine protection.
- Periodic Inspections: Refrigerant leak inspections may be required by legislation. Contact the local dealer for more information.
- Professional Maintenance: Disassembly and internal cleaning require specialized techniques. An authorized contractor from the dealer is recommended for maintenance inspections.
- Troubleshooting Guide: Provides solutions for common issues such as the unit not operating, stopping sometimes, inability to change COOL/HEAT, fan operation without cooling/heating, incorrect fan strength, white mist, noise, and dust emission. It also includes checks to perform before requesting servicing, such as power supply, circuit breaker status, and obstruction of air inlets/outlets.
- After-Sale Service: Instructions for requesting repairs, repairs after warranty expiration, maintenance inspection, relocation, and disposal. It emphasizes contacting the dealer for all these services, especially for handling refrigerant and ensuring proper installation/modification.
