**Product Specifications:**
**Brand:** PURPAVWINNER
**Compatibility:** Suitable for Haier water heaters, electric water heater magnesium rods, and protecting the inner tank for water quality purification.
**Durability:** Protects the machine, ensuring long-lasting protection for the machine and inner tank, purifying water quality with high-purity magnesium for prolonged machine use and purer water quality.
**Function of Magnesium Rod:** When scale adheres to the magnesium rod, it consumes its own magnesium, generating tiny magnesium ions and water, which are then flushed out of the water heater through water flow to reduce scale, purify water quality, and protect the inner tank and heating rod.
**Features:** Multi-layer filtration for water purification, effectively reducing corrosion caused by scale on the inner tank, preventing leakage and electrical issues.
**Selection Guide for Magnesium Rod:** Refer to the label for selecting the appropriate specifications, including China Energy Label, producer name (Haier Kitchen and Bathroom Appliances), model number (F50-21W81(E)), low energy consumption, inherent energy consumption coefficient, hot water output rate, and capacity.
**Installation:** Choose the magnesium rod based on the model number and capacity, with options for different sizes and colors of nuts.
**Replacement Method:** Follow the steps for safe and efficient replacement of the magnesium rod, including disconnecting power, closing the water inlet valve, draining water, removing the old rod, installing the new rod, and ensuring proper sealing.
