General assembly Drawing
Product Installation Method
Phase 1: Structural Preparation
- Construct 40×40mm aluminum alloy frame (EN AW-6063 T6 grade, yield strength ≥215 MPa)
- Secure to concrete ceiling using M10 wedge anchors (minimum embedment depth: 65mm)

Phase 2: Unit Mounting
- Attach enclosure using vibration-isolating brackets (natural frequency ≤12 Hz)
- Torque M8 stainless steel bolts to 25 N·m ±10% (ASME B18.2.1-2024 specification)

Phase 3: Duct Integration
- Align helical duct connector using laser level (≤0.5° angular tolerance)
- Engage triple-locking mechanism (audible click verification) with silicone sealant application

Performance Validation
- Airflow Test: Hot-wire anemometer calibration (accuracy: ±1.2% FS)
- Leakage Check: 50 Pa pressure differential test per AMCA 500-L:2023
- Noise Certification: Reverberation room testing per ISO 3741:2025
