Installation Guidelines

1. Preparation: Verify that the hose length matches the required run, accounting for bends and fittings. Trim any excess material using a sharp utility knife.
2. Connection: Use compatible compression or flared fittings rated for the same temperature range. Ensure all connections are tightened to manufacturer torque specifications.
3. Bending: Maintain the minimum bend radius of 30 mm during installation to prevent internal damage.
4. Securing: Employ hose clamps or brackets at intervals no greater than 1.5 m to secure the hose against vibration and movement.
5. Testing: After assembly, perform a pressure test at 80% of the rated maximum before operating the system.

Maintenance Practices

• Inspect for visible wear, cracks, or bulges every six months.
• Check fittings and clamps for tightness; re‑torque if necessary.
• Avoid exposure to ultraviolet light for prolonged periods; use protective covers when stored outdoors.
• Replace the hose after a maximum service life of five years or upon detection of any degradation.
