Maintenance: What kind of maintenance is required for the whole house UV system?Updated 3 months ago

Every whole house UV system contains a UV sleeve to protect the UV light bulb. Overtime, minerals in the water may slowly form a coating on the sleeve during normal operation. This coating must be removed from the sleeve because it reduces the amount of UV light reaching the water, thereby reducing purification performance. Therefore, it is recommended to use scale removers such as Lime Away™ or CLR™, with soft, lint-free, and chemical-free cloth to remove any coatings adhering to the sleeve. Depending on the quality of the process water, we suggest you clean the sleeve regularly, about 3-4 times a year.

Cleaning the lamp is not necessary because the lamp itself is protected by the sleeve. The need to clean the sleeve will be indicated by the UV alarm on the UV-WHS-14-PLUS, UV-WHS-28, UV-WHS-47 models. If the process water entering the UV system is sufficiently filtered, then the cleaning requirement would be less frequent. If you have the whole house sediment filter upgrade option, the filter should be replaced every 6-8 months depending on your water quality.
