Maintenance Information

Lamp Tube Cleaning: Regularly wipe fingerprints and dust from the lamp tube and filter surface using anhydrous alcohol to maintain light transmittance.

Water System Maintenance: The spray system must use deionized or distilled water, and filters should be replaced regularly to prevent nozzle clogging.

Heat Sink Cleaning: Periodically inspect the intake air filter of the air-cooling system and remove accumulated dust to ensure effective cooling.

Lamp Life Management: Closely monitor cumulative lamp usage time. Replace lamps promptly when irradiance fails to meet set values.
