Maintenance & Cleaning Instructions

Check the hood surface and remove dust.

Wipe the front surface and surroundings with disinfectant before use.

Turn the fan voltage knob to "zero" and check fuses for integrity.

Turn on the main power switch, gradually adjust the knob to raise voltage until vertical airflow speed reaches ≥0.35m/s.

After use, return voltage to "zero" before turning off the power switch.

Remove the faceplate weekly, clean with WFI (Water for Injection), then wipe with 75% alcohol.

Replace HEPA filter when airflow speed cannot exceed 0.2m/s due to reduced air volume or pressure.

When replacing the filter, open the faceplate, loosen fixing bolts, replace the filter, tighten securely, and reinstall the faceplate.
