Installation

Unpack and inspect all components. Ensure installation site can support unit weight (45 kg).

Select mounting location: Ensure adequate clearance (min. 50 cm on all sides).
Secure mounting brackets: Use provided hardware to attach to wall/ceiling/floor.
Connect ducting: Attach appropriate ductwork to intake and exhaust ports.
Electrical connection: Have qualified electrician connect to 3-phase power supply.
Ground the unit: Connect grounding wire to proper earth ground.

WARNING! Unit is heavy; use proper lifting equipment. Ensure power is disconnected during installation.

First-Time Setup

After installation, perform initial setup before first use.

Power connection: Verify correct voltage (400V AC) and phase sequence.
System check: Ensure all fasteners are tight and ducting is secure.
Test rotation: Momentarily power on to confirm correct fan rotation direction.
Speed calibration: Set minimum and maximum speed limits on VFD controller.
Safety test: Verify thermal overload protection activates correctly.

CAUTION! Never operate without proper ducting attached. Keep hands clear of moving parts.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Unit will not start	Power supply/thermal cut-out	Check 3-phase power; reset thermal protector; verify START button.
Reduced airflow	Blocked ducts/damaged blades	Clear obstructions; inspect and clean blades; check duct connections.
Unusual noise	Loose components/bearing wear	Tighten all fasteners; inspect and replace bearings if necessary.
Overheating	High ambient temp/blocked vents	Ensure adequate ventilation; clean air intake; reduce operating speed.
Vibration	Imbalance/loose mounting	Check blade balance; tighten mounting hardware; ensure stable surface.

Reset: Press RESET button after addressing fault condition.
