Make sure all parts are present and clean.

The installation steps are as follows:
- First, connect the "inlet three-way connector" to the water source pipeline. This is the starting point for assembling the household RO water purification system, as it connects all the subsequent components.
- Install the "high-voltage switch" on one interface of the "inlet three-way connector". The high-voltage switch is used to control the start and stop of the RO water purification system, saving water resources and energy.
- Connect the "inlet water solenoid valve" to the other interface of the "high-voltage switch". The inlet water solenoid valve controls the water flow and ensures a sufficient water supply for the RO system to operate.
- Install the "first-stage filter cartridge" on the outlet of the "inlet water solenoid valve". The first-stage filter cartridge is typically a coarse filter used for pre-treating water, removing large particles and suspended substances.
- Connect the "10-inch filter cartridge" to the outlet of the "first-stage filter cartridge". The 10-inch filter cartridge usually contains granular activated carbon, further removing odors and residual chlorine from the water, improving water quality.
- Install the "Second-stage filter cartridge" on the outlet of the "10-inch filter cartridge". The second-stage filter cartridge is typically a finer activated carbon filter, further purifying the water.
- Connect the "third-stage filter cartridge" to the outlet of the "Second-stage filter cartridge". The third-stage filter cartridge usually contains higher-level filtration media to remove tiny particles and bacteria, making the water cleaner.
- Install the "Lefoo Ro booster Pump" after the "third-stage filter cartridge". The booster pump is used to increase the water inlet pressure, enhancing the efficiency of the RO system.
- Connect the "Wire inside the union" to ensure tight connections within the system to prevent leakage.
- Connect the "Dow RO membrane casing" to the third interface of the "inlet three-way connector". The RO membrane casing houses the RO membrane component, which is the core of the RO system.
- Install the "RO membrane" after the "Lefoo Ro water pressure Pump". The RO membrane utilizes reverse osmosis technology to effectively remove bacteria, heavy metals, and other pollutants, providing high-purity water.
- Connect the "flushing solenoid valve" to the outlet of the "RO membrane casing". The flushing solenoid valve is used to periodically flush the RO membrane, removing impurities and deposits that could clog the membrane, ensuring its efficient operation.
- Connect the "quick connect check valve" to the outlet of the "flushing solenoid valve". The check valve prevents backflow contamination of the RO membrane, ensuring the normal operation of the RO system.
- Connect the "pressure gauge" to the water inlet of the "RO membrane casing". The pressure gauge is used to monitor the operating pressure of the RO system, ensuring its proper functioning.
- Install the "pressure tank ball valve" on the second interface of the "inlet three-way connector". The pressure tank ball valve controls the water flow into the pressure tank, allowing for water pressure adjustment.
- Install the "Alloy pressure tank" on the "pressure tank ball valve". The pressure tank stores filtered water, ensuring a readily available supply of purified water for household use.
- Finally, install the "Filtered water faucet" on the "T33 filter cartridge". The filtered water faucet is a dedicated tap for accessing purified water, connected to the outlet of the T33 filter cartridge.
When using and maintaining the water purification system, here are some suggestions and precautions:
Regularly clean and replace the filter cartridges:
The filter cartridges are crucial for the water purification system, so regular cleaning or replacement is essential to maintain water quality. Follow the manufacturer's recommendations for filter maintenance and replacement based on usage.
Observe pressure and water quality:
Pay attention to the working pressure and water quality of the water purification system. High pressure or declining water quality may indicate filter cartridge aging or malfunction, which should be addressed promptly to maintain water purification effectiveness.
Periodically flush the RO membrane:
The RO membrane is a key component of the system, and regular flushing helps remove impurities and extend the membrane's lifespan.
Avoid exposure to sunlight and high temperatures:
Install the water purification system in a location protected from direct sunlight and high temperatures to ensure proper operation and longevity.
Regular maintenance:
Periodically check pipe connections and valves to ensure there are no leaks. If any issues are found, perform repairs or replace components promptly.
Maintain hygiene:
Keep the area around the water purification system clean, and regularly clean the external casing to ensure the filtered water faucet remains sanitary.
Be mindful of water usage habits:
Minimize water wastage and use the water purification system efficiently to protect the environment and save on water costs.
I hope these suggestions are helpful in ensuring your household RO water purification system consistently provides high-quality purified drinking water.
