General assembly Drawing

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
