MAINTENANCE
The water purifier is designed to operate with a minimal amount of maintenance, providing the water quality does not
exceed maximum concentration levels, see “Water Quality” in the “Product Application” section. Ordinary mainte-
nance consists of;
• Lamp replacement is recommended every 10,000 hours of operation, approximately 12 months of continuous service.
• Cleaning of the quartz sleeve, when conditions warrant.
• Always disconnect the water supply and completely drain the water purifier if it will be subjected to
temperatures below freezing, for extended periods of time.
I
NSPECTION
1. Regularly inspect the water purifier to ensure that the germicidal lamp is still in operation.
• On purifiers not equipped with the Ultraviolet Monitor, lamp operation can be verified by a visible glow
through the translucent sight port. This provides an indication of lamp operation and does not indicate the level
of ultraviolet intensity or transmission through the water.
• On purifiers so equipped, the Guardian
™ Ultraviolet Monitor provides visual indication of the ultraviolet
intensity through the quartz sleeve and water in the purifier chamber.
2. To ensure proper operation of the water purifier, regular biological testing should be performed on a schedule
recommended by local public health authorities, or at minimum; at installation, quarterly for the first year of
service and annually, at lamp replacement, for the life of the water purifier.
