This document introduces the specifications and safety precautions of a water heater named FCD-H40H(E). The water heater uses AC 220V/50Hz power supply and requires a dedicated outlet with reliable grounding. Before use, it is necessary to check whether the electric meter and wire diameter meet the requirements. After installation, it is necessary to fill the tank with water before connecting the power supply. In cold regions, the water should be drained when the water heater is not in use for a long time to prevent freezing damage. The installation location should be on a solid and firm wall and avoid places where drainage is not possible.
This manual provides safety warnings, installation guidelines, and operating instructions for Haier’s FCD‑H series household water heaters (40 L, 50 L, 60 L, 80 L). It explains the required 220 V / 50 Hz power source, dedicated grounding, and proper mounting on a solid wall.
The document also covers routine cleaning, maintenance of the magnesium rod, troubleshooting common issues, and lists the technical specifications such as rated power, capacity, pressure, and IPX4 waterproof rating. This manual is written in Chinese.

It must be connected to a dedicated 220 V / 50 Hz AC outlet with reliable grounding.
Mount the unit on a solid wall using the supplied brackets, drill four 12 mm holes, attach the expansion bolts, and connect the water pipes with G1/2 fittings, ensuring a dedicated socket is used.
Turn off the power, wipe the exterior with a damp cloth and mild detergent, avoid gasoline or abrasive cleaners, and follow the internal cleaning steps for the heating tube and inner tank every three years.
The magnesium rod should be inspected regularly and replaced roughly every two years to maintain corrosion protection.
