Product Installation Method

Phase 1: Structural Reinforcement

• Fabricate 50×50mm steel support frame (minimum tensile strength: 400 MPa)
• Anchor to substrate using Hilti HUS-HR 10.8 M12 anchors (embedment depth: 75mm)

Phase 2: System Assembly

• Mount unit on anti-resonance pads (Shore D 55 hardness), torque M10 bolts to 35 N·m ±5%
• Align ductwork using photogrammetric laser alignment (≤0.3° angular deviation)

Phase 3: Operational Validation

• Perform thermal imaging scan to confirm <5°C motor winding temperature rise
• Conduct spectral analysis to verify vibration velocity <1.8 mm/s (ISO 10816-8:2025)

Sector-Specific Applications
