Eliminating overly caustic environments in indoor aquatic facilities


All process equipment needs to be maintained and UV is no exception. Typically, each UV chamber will require a regularly scheduled maintenance program consisting of approximately four hours every six months. There are a limited number of expendable components, which will require manual cleaning and/or replacement.

Often, UV is installed in a bypass to allow the system to be serviced while the pool remains open. Unless mandated by health code, a UV system that is out of service for one or two days should not be a concern. Although chloramine levels rise steadily, however, not rapid enough to necessitate closing the pool.

It is highly advised to have a factory-trained technician perform the first few service calls to allow onsite technical service staff to train alongside. The UV lamp and quartz sleeve are relatively fragile and expensive; if a factory technician should break or damage any components during service, the customer will not have to pay for additional parts.

Another benefit to having factory-certified service is to assure proper performance, thus establishing a baseline the customer can expect year after year. Unlike chemical feed systems, which oxidize, UV is nothing more than powerful lamp(s) in a 316-L stainless steel body, and if maintained properly, it will last many years. Some manufacturers also offer extended warranties if service contracts with factory-trained technicians are in place.
