Other models (GWCN09B6NK1CA, GWHN09B6NK1CA, GWCN12B6NK1CA, GWHN12B6NK1CA, GWCN09B6NK3CA, GWHN09B6NK3CA, GWCN12B6NK3CA, GWHN12B6NK3CA, GWCN12B7NK1CA, GWHN12B7NK1CA, GWCN12B7NK3CA, GWHN12B7NK3CA) have similar specifications but with varying capacities, power inputs, and sound levels, often using R22 or R410A refrigerants and operating on 1PH 220-240V~ 50Hz. Compressor types vary between Rolling Piston and Scroll.
Usage Features
- Remote Control Operation: The units are primarily controlled via a wireless remote.
- Temperature Setting: Users can set the desired room temperature (Tpreset) within a range of 16~30°C.
- Cooling Mode: The unit cools when the ambient temperature (Tamb) is 1°C above Tpreset. It stops cooling when Tamb is 1°C below Tpreset.
- Dry Mode: Operates under DRY cooling when Tamb is 2°C above Tpreset. The indoor fan runs at low speed, and the compressor cycles on/off to dehumidify.
- Heat Mode (for heating units): Heats when Tamb is 2°C below Tset. The reversal valve, compressor, and outdoor fan run. It stops heating when Tamb is 4°C above Tset.
- Fan Mode: Only the indoor fan runs at a set speed.
- Auto Mode: The system automatically selects the appropriate mode (cool, dehumidify, heat, or fan) based on ambient temperature.
- Sleep Function: Automatically adjusts the preset temperature over time in cooling/dehumidifying (rises by 2°C) or heating (decreases by 2°C) modes to optimize comfort and energy efficiency.
- Swing Motor Control: The guide louver adjusts its position for air outlet. It can swing between D1 and D3 in cool mode, and L and D3 in heat mode.
- Super Function: Activates a super high fan speed for rapid cooling or heating.
- Timer Function: Allows setting automatic on/off times.
- Memory Function: Retains settings (mode, fan speed, temperature, timing, swing, super) from before power off.
- Display: Features RUN, COOL, HEAT, and DRY indicators, and a double 8 module display for setting temperature.
- Buzzer: Provides audible feedback for operations.
- Manual Switch: Allows basic operation (Auto, Test, Run, Stop) directly from the unit.
Maintenance Features
- Protection Mechanisms:
- Antifreeze Protection: Stops the compressor and outdoor fan if antifreeze conditions are detected, resuming operation after a set delay once conditions normalize.
- High Temp. Protection: Stops the outdoor fan if the evaporator tube temperature is too high, restarting when it returns to normal.
- Noise Silencing Protection: Manages reversal valve operation during mode switching or shutdown to reduce noise.
- PG Motor Block Protection: If the indoor fan's PG motor is blocked, all loads stop, and a "H6" malfunction code is displayed. Power cycling is required to reset.
- Disassembly Procedures (Indoor Unit): Detailed steps are provided for disassembling various components:
- Front panel
- Filter
- Guide louver
- Body case
- Electric box
- Water-tray sub-assembly
- Evaporator
- Motor
- Cross flow fan
- Disassembly Procedures (Outdoor Unit): Detailed steps are provided for disassembling various components:
- Top cover
- Net cover
- Rear grill
- Electric box
- Right side plate
- Axial flow fan
- Motor and motor support
- Capillary sub-assembly
- Valves (big and small)
- Compressor
- 4-way valve (for cooling/heating units)
- Troubleshooting Guide: Provides a systematic approach to identify and resolve common issues such as:
- Unit not starting (breaker trips, no power, remote control issues)
- Poor cooling/heating operation (refrigerant issues, airflow blockage, fan malfunction, improper installation)
- Compressor overheating
- Swing fan not running
- Water leakage
- Abnormal sounds and shakes
The manual emphasizes that technical data is subject to change and advises referring to the unit's nameplate for the most accurate information.
