Frequently Asked Questions (FAQ)
Q: What does the 1-year warranty cover?
A: The warranty covers all manufacturing defects in materials and workmanship for parts and labor. It does not cover damage caused by misuse, unauthorized modifications, or normal wear items such as gaskets and diaphragms (which are consumable). Extended warranty options are available upon request.Q: What kind of on-site training is provided?
A: Our technicians will visit your site to conduct a comprehensive training session covering system installation, startup, calibration, daily operation, troubleshooting, and routine maintenance. Training duration is typically 1 to 3 days depending on the system complexity and your team's experience.Q: Can the dosing system handle liquid sodium hypochlorite (bleach)?
A: Yes, the system is designed for liquid chlorine solutions, including sodium hypochlorite (up to 12% concentration) and other common disinfectants. For higher concentrations or aggressive chemicals, we recommend PVDF wetted parts. Please specify your chemical type when ordering.Q: How does the automatic control work?
A: The system uses a PLC controller that can accept signals from a residual chlorine analyzer, flow meter, or a 4-20mA external sensor. It adjusts the pump stroke or speed proportionally to maintain the set dosing rate. Manual override is also available for local control.Q: What are the power requirements?
A: Standard models are available for 220V/50Hz single-phase, 380V/50Hz three-phase, and 110V/60Hz. We can customize the voltage and frequency to match your local grid. Please specify your power supply when placing an order.Q: How often does the system need maintenance?
A: Routine maintenance includes checking and cleaning the filter weekly, inspecting pump oil level monthly (for piston pumps), and replacing diaphragms or seals every 3-6 months depending on usage. The PLC system has self-diagnostic features to alert you of any issues. Detailed maintenance schedule is provided in the manual.Q: Can I integrate this system with my existing SCADA or remote monitoring?
A: Yes, the standard PLC has RS485, Modbus RTU communication ports. Optional Ethernet/IP, Profibus, or 4G remote monitoring modules can be added. Our engineers will work with you to ensure seamless integration.Q: What is the lead time and shipping process?
A: Lead time is typically 15-30 working days after order confirmation, depending on configuration. We ship via sea or air from Tianjin Port, with full export documentation. On-site training is scheduled after the system arrives and is installed. Contact us for a precise delivery timeline.
