3. Specifications

The filter housing has passed 150,000 cycle water hammer tests (1 MPa) and a highest hydrostatic test of 1160 psi (8 MPa).

4. Setup and Installation

This pre-filter is designed for cold water pipe installation and central purification. It should be installed at the source of the water pipe in your home.

Installation Steps:

1. Select Installation Position: Choose a location where the bottom of the product has sufficient distance from the ground for easy installation and maintenance. Ensure it is close to convenient drainage for flushing operations.
2. Close Water Supply: Close the main intake valve to your home and discharge any remaining water from the pipes.
3. Orient Filter Correctly: Pay attention to the flow direction arrow (IN/OUT) on the product's top cover. This must align with the direction of your tap water flow.
4. Connect Adapters: Wrap the provided 1/2 inch internal thread adapters with raw material tape (Teflon tape) and connect them to the inner screw tooth interface at both ends of the product.
5. Connect to Water Pipes: Connect the hexagonal nut at the inlet end of the product to the water meter outlet pipe. Connect the hexagonal nut at the outlet end to your indoor water pipe.
6. Check for Leaks: After securing all connections, slowly open the main intake valve. Carefully observe all connections for any leakage or seepage.
7. Initial Flush: Operate the cleaning mechanism (see Operation section) 2-3 times to clean the scraper and sewage valve, ensuring normal operation. Address any leaks immediately.

Installation Precautions:

• Confirm all accessories are present and the product is undamaged before installation.
• Avoid installing near ultraviolet light, heat sources, fuel, or various chemicals.
• Ensure the connecting thread is evenly wound with raw material tape to achieve a proper seal and prevent leaks.
• When tightening hexagonal nuts with a wrench, ensure other components do not rotate to maintain reliable assembly.

5. Operation

Once the pre-filter is installed and the main water valve is open, the filter will begin to work. Over time, the transparent housing will show accumulated impurities. The AL-PRE1 features a simple and convenient self-cleaning operation.

6. Maintenance

Regular cleaning is essential to maintain optimal water output and pressure. The AL-PRE1 is designed for easy, tool-free cleaning without disassembling the filter.

Cleaning and Flushing Instructions:

1. Activate Scraper: Rotate the lower cover of the transparent housing clockwise or counter-clockwise. This action drives the double-sided scraper to clean the inner and outer surfaces of the filter screen. Rotate several turns left and right to effectively dislodge impurities.
2. Flush Impurities: While scraping, open the flushing drain valve at the bottom of the unit to discharge the loosened impurities. Alternatively, you can scrape first, then open the drain valve to flush out the accumulated debris.
3. Repeat Process: Repeat steps 1 and 2 for 2-3 cycles to ensure a thorough cleaning. This will restore the filter to normal operation.

The entire cleaning process can be completed without disassembling the filter, making it simple and convenient for any adult in the household.

Recommended Maintenance Schedule:

• Clean the filter element every 15-30 days, depending on water quality.
• Replace the filter element every 1-3 years, depending on water quality and usage.

8. User Tips

• Filter Function: This pre-filter is designed to remove suspended solids like sand, rust, and sediment. It does not reduce Total Dissolved Solids (TDS), eliminate salt, or filter chlorine. For these, additional filtration systems (like RO purifiers or carbon filters) would be needed.
• Pipe Adapters: The product includes 1/2 inch internal thread adapters. If your plumbing uses 3/4 inch or 1 inch pipes, you will need to purchase the appropriate external thread adapters separately.
• Water Pressure: The filter is designed to maintain water pressure. If you experience a drop in pressure, it's likely due to a clogged filter element requiring cleaning.
• Hot Water Use: While primarily for cold water lines, the filter's robust construction (food-grade PC cover, lead-free brass) suggests it can withstand typical household hot water temperatures (up to 40°C).
• Self-Cleaning: The filter features a convenient self-cleaning mechanism. Regularly rotating the bottom part and opening the drain valve will flush out accumulated debris without needing to dismantle the unit.
• Outdoor Installation: The product is suitable for outdoor use, but consider extreme temperatures. The housing is tested to withstand freezing down to -30°C and high pressures.
