Precautions for backwashing filters

Installation Guidelines

1. Specification Matching:

• Select filters compatible with pipeline dimensions. If flow capacity is insufficient, install multiple filters in parallel or use bypass filtration.

2. Optimal Placement:

• Install near the pressure source to avoid low inlet pressure. Prioritize proximity to protected system components.

3. Piping Configuration:

• Install in series with main pipelines. Include a bypass line with shutoff ball valves (inlet/outlet/bypass) for uninterrupted supply during maintenance. Add a check valve at the outlet if backflow risks exist.

4. Temperature Limits:

• Ensure fluid temperature does not exceed the filter’s rated tolerance.

5. Power & Drainage:

• Provide 380V three-phase AC power (three-phase, four-wire). Limit drain pipe length to ≤5 meters to prevent backpressure.

6. System-Specific Considerations:

• DC systems: Prioritize precision, pretreatment, and pressure control.

• Intermittent systems: Avoid timer-controlled models.

7. Environmental Protection:

• Ensure installation sites are dry, waterproof, and moisture-resistant.

Long-Term Shutdown Protocol

• Before seasonal/offline periods, inject corrosion inhibitors into the system and maintain wet layup protection to minimize corrosion.

Operational Steps

1. Pre-Start Checks:

• Confirm filter is in ready state.

• Inspect all connections for tightness.

• Ensure electrical control box is dry.

2. Power-Up:

• Connect power; a green indicator confirms operational readiness.

  
  

Critical Notes:

• Maintain dry hands when handling electrical components.

• Prevent water ingress into the control box during operation.

The system is factory-calibrated. Adjust parameters (manual/auto modes) only if operational needs deviate from default settings.
