Usage Methods

• Installation: Install the spiral deaerator in the water system pipeline, ensuring the inlet and outlet directions are consistent with the water flow direction. The device should be installed in a well-ventilated, dry, and stable location, with enough space around it for maintenance. Ensure all pipeline connections are tight to avoid water leakage.

• Pre-Operation Check: Before starting, confirm that the water quality, temperature, and pressure meet the device’s technical requirements (pH > 6.5, water temperature < 90°C, working pressure < 1.0 MPa or customized pressure). Check the device for physical damage and ensure the internal components are intact.

• Start-Up Operation: Turn on the water supply valve and start the system. The spiral deaerator will automatically perform degassing and filtration functions. During operation, monitor the water flow and pressure to ensure stable performance.

• Daily Monitoring: Regularly check the operating status of the device, including pressure drop, water flow, and degassing effect. Observe the discharge of air bubbles and impurities to ensure the device is working normally.

• Maintenance: Minimal maintenance is required. Clean the filter component every 3–6 months (or according to impurity content) to remove accumulated debris and ensure filtration efficiency. Check the device’s sealing parts for leakage and replace them if necessary. For customized high-pressure models, inspect the pressure-bearing components regularly to ensure safety.

Safety Precautions

• Pressure Safety: Ensure the device operates within the rated working pressure (standard < 1.0 MPa; customized < 2.5 MPa). Do not exceed the rated pressure, as this may damage the device and cause water leakage. Before maintenance, close the inlet and outlet valves and release the internal pressure to avoid injury.

• Temperature Safety: Do not allow the water temperature flowing through the device to exceed 90°C, as this may affect the degassing and filtration effect and damage the device’s internal components.

• Water Quality Safety: Ensure the inlet water quality meets the requirements (pH > 6.5, total hardness < 700 mg/L, total hardness + total alkalinity < 800 mg/L). If the water quality exceeds the standard, pre-treat the water first to avoid device blockage or performance degradation.

• Mechanical Safety: Do not disassemble the device during operation. Use appropriate tools for installation and maintenance to avoid damaging the pipeline or device components. Wear protective gloves when cleaning the filter component to avoid scratches.

• Operating Environment: Install the device in an environment that meets the ambient conditions (temperature -40°C to 55°C, relative humidity < 90% at 20°C or below). Avoid installing it in areas with high humidity, corrosive gases, or direct sunlight to prevent device damage.

• Unauthorized Disassembly: Do not disassemble the device’s internal components without authorization. If there is a fault (e.g., abnormal pressure drop, poor degassing effect), stop the device and contact professional after-sales personnel for maintenance.
