5. Operation & Maintenance Guidelines

1. Pressure Monitoring – Check the pressure gauge during operation. Replace filter elements when pressure reaches the

 recommended change-out threshold.

2. Pre-Use Inspection – Inspect hoses, seals, and connections before each use. Replace worn components immediately.

3. Element Replacement – Replace both primary and secondary elements simultaneously for balanced performance. 

Use only recommended replacement elements.

4. Tank Cleaning – If equipped with a self-contained tank, clean periodically to prevent sediment accumulation.

5. Caster Maintenance – Keep wheels clean and bearings lubricated. Replace damaged casters promptly.

6. Explosion-Proof Precautions – For EX versions, ensure proper grounding and follow hazardous area safety protocols.

6. FAQ (Frequently Asked Questions)

Q1: What is the difference between LYC-C and other LYC series filter carts?

A: The LYC-C series features a fully enclosed metal housing that protects internal components from external environmental 

pollution. It also offers optional self-contained tank configuration and explosion-proof options not available on all 

standard LYC models.

Q2: What filtration precision can the LYC-C achieve?

A: The LYC-C employs dual-stage filtration. Secondary fine filtration precision options include 3μm, 5μm, 10μm, and 20μm. 

Choose the precision based on your system's cleanliness requirements and component sensitivity.

Q3: What types of hydraulic fluids are compatible?

A: Standard configuration handles general hydraulic oil. Special configurations are available for: water-glycol fluids (BH option) 

and phosphate ester hydraulic fluids (V option). Please specify your fluid type when ordering.

Q4: Does the LYC-C include a self-contained oil tank?

A: The self-contained tank is optional. When equipped, oil in the self-provided tank can be filtered to standard through 

self-circulation, then directly injected into hydraulic systems—ideal for servo valve and proportional valve applications.

Q5: Can the LYC-C be used for flammable liquids?

A: Yes. The LYC-C offers an explosion-proof (EX) configuration suitable for petroleum, chemical, and aerospace 

applications—filtering gasoline, diesel, kerosene, and other flammable media. Please specify EX requirement when ordering.

Q6: How do I know when to replace the filter elements?

A: Monitor the panel-mounted pressure gauge. Replace elements when the pressure reaches the recommended change-out 

value (typically 2–3× initial clean pressure drop). The gauge provides real-time indication of contamination status.

Q7: Is the LYC-C suitable for continuous operation?

A: Yes. The magnetic starter with thermal overload relay protection ensures safe continuous operation. The internal gear pump 

is designed for reliable long-term performance with minimal maintenance.

Q8: What is the maximum oil viscosity the pump can handle?

A: The LYC-C is rated for medium viscosity up to 160 cSt. For higher viscosity oils, please consult our technical team for pump

 sizing adjustments.

Q9: Can I use this filter cart for both suction and pressure applications?

A: The LYC-C is primarily designed for suction-side filtration and transfer applications with a rated pressure of 0.6 MPa. For

 high-pressure systems, please consult our engineering team for suitable models.

Q10: How does the quick-opening end cover work?

A: The top-mounted end cover features a quick-release mechanism that can be opened and closed without tools—enabling

 fast, easy filter element access and reducing maintenance downtime.

Q11: What documentation is provided with each unit?

A: Each LYC-C unit is supplied with a certificate of conformance, factory test report, dimensional inspection record, operation

 manual, and parts list. Additional certifications are available upon request.

Q12: Are custom flow rates available?

A: Yes. While standard models cover 32–100 L/min, custom flow configurations are available upon request. Please provide your

 system requirements for a tailored solution.

Q13: Does the LYC-C include a bypass valve?

A: Yes, an integrated overflow bypass valve protects the system if filter elements become clogged and replacement is 

temporarily delayed. However, continuous bypass operation should be avoided.

Q14: What is the recommended maintenance schedule?

A: Key maintenance tasks include: checking pressure gauge during each use; inspecting hoses and seals weekly; replacing 

filter elements per differential pressure indication; and cleaning the self-contained tank monthly (if equipped). Annual 

comprehensive inspection is recommended.
