This manual provides an overview of the Haier FL4W90 display cabinet, including its design, component layout, and the refrigeration principle that uses R22 refrigerant. It describes the cabinet’s dimensions, temperature control range, and lighting system.
The document also details proper usage, daily cleaning, maintenance procedures, and technical specifications such as effective volume, cooling load, and recommended operating environment. Safety guidelines and voltage tolerance are included to ensure reliable operation. This manual is written in Chinese.
| Effective Volume | 0.874 m³ (model GK0.67L4F) / 1.311 m³ (model GK0.75L4F) |
|---|---|
| Display Area | 3.48 m² – 6.975 m² depending on model |
| Working Temperature Range | -2 °C to +2 °C |
| Cooling Load | 1350 W – 2700 W |
| Fan Size | 38 mm × 3 mm (standard) / 38 mm × 5 mm (larger model) |
| Voltage Tolerance | ±10 % of nominal voltage |
| Defrost Frequency | 6 times per 24 h, each about 20 minutes |
The cabinet should be used in an environment where the room temperature is below 25 °C and relative humidity is below 60 %.
The supply voltage should stay within ±10 % of the nominal voltage; use a suitable stabilizer if the voltage is unstable.
Defrost cycles are set to occur six times per 24 hours, with each cycle lasting about 20 minutes.
