**2、 Core component installation specifications**
**1. Host installation**
-* * Basic Requirements * *:
-Concrete foundation thickness ≥ 300mm, strength C25 or above
-Pre embedded bolt specifications: M16~M24 (selected according to the weight of the fan)
-Horizontal deviation ≤ 0.2mm/m
-* * Shock absorption measures * *:
-Rubber shock absorber pad: static compression capacity of 5-10mm
-Spring shock absorber: suitable for models with a power greater than 55kW
**2. Pipeline connection**
|* * Components * * | Installation Points | Diagram Annotations|
|----------------|-------------------------------------|----------------------|
|Inlet duct | Length ≤ 3 times the pipe diameter, avoid sharp bends (bend R ≥ 1.5D) |! [Air intake duct]（ https://example.com/inlet ) |
|Exhaust pipe | Upward pipe inclination angle ≥ 15 °, anti condensation water backflow |! [Exhaust pipe]（ https://example.com/outlet ) |
|Soft connection | Length=10D (D is the pipe diameter), non twisted installation |! [Soft Connection]（ https://example.com/flex ) |
**3. Silencer installation**
-* * Intake muffler * *:
-When the distance from the fan inlet is ≤ 1.5D, a drainage valve should be installed vertically
-* * Exhaust muffler * *:
-Directly connect the fan outlet flange and prohibit reverse installation

**3、 Electrical and Control Installation**
1. * * Cable wiring * *:
-Power ≤ 30kW: VV-3 × 16mm2 cable
-Power>30kW: VV-3 × 25mm2 cable+independent grounding wire
2. * * Control Cabinet * *:
-Protection level IP55, distance from fan ≤ 10m
-The frequency converter needs to reserve a heat dissipation space (≥ 500mm)

-Red Arrow: Airflow Direction
-* * Green Box * *: Must Install Shock Absorber Components
-Yellow Label: Maintenance Operating Space (≥ 800mm)
---
**Precautions * *:
1. It is strictly prohibited to install regulating valves on the intake pipe (which may cause negative pressure to damage the seal)
2. Before the first operation, it is necessary to manually turn the rotor 2-3 times (check for rotor jamming)
3. Complete installation information can be obtained from the manufacturer:
-Basic Load Diagram (PDF/CAD format)
-Explosion diagram (including part numbers)
If you need a specific installation diagram for the model (such as -150), please provide the fan parameters for accurate matching.
