Installation Guidelines
Critical Requirements
1. System cleanliness is essential - Flush lines and replace all filters
2. Use new hydraulic oil - Do not reuse contaminated oil
3. Replace suction line seals - Air leaks cause pump failure
4. Prime the pump before startup - Never run dry
5. Check alignment - Misalignment causes premature shaft seal failure
Post-Installation Checklist
- Check for unusual noise during initial operation
- Verify pressure readings match specifications
- Inspect for external leaks after first hour of operation
- Change return filter after 50 hours of operation
Due to the complexity of hydraulic systems, installation by qualified technicians is strongly recommended.
