Installation tips

Unplug the CT-500-UV from the electrical outlet before opening the UV chamber.
Allow the unit to cool if it has been running, as UV bulbs can become warm.
Open the UV chamber according to the system’s instructions.
Carefully remove the old UV bulb—avoid touching the glass of the new bulb with bare hands; use gloves or a clean cloth.
Insert the new UV bulb securely into the socket, ensuring proper alignment.
Close the UV chamber and plug the unit back into a grounded outlet.
Turn on the water to activate the UV system and confirm the UV indicator light is functioning.
Replace UV bulbs every 12 months for optimal germicidal performance, even if the bulb still appears to light.
