4A. UV Reactor System Electromechanical Overview
CAUTION Disconnect power before performing service. Refer to the IMPORTANT SAFETY INSTRUCTIONS displayed in
the front of this manual. Refer to Figures 4, 5, and 6.
NOTE: To replace a UV lamp, follow only SECTIONS 4B-1 AND 4B-4.
There are two lamps in each UV reactor of the UV-C Pro powered by an energy ecient electronic ballast. Water enters the
UV reactor and is exposed to UV-C. The water exits through the top of the UV reactor and returns to the process plumbing.
UV Reactor
Figure 4: UV-C Pro Electro-Mechanical Overview
4B. UV Reactor Service and Maintenance
• Each UV Reactor contains two UV lamps and two quartz tubes.
• The UV lamps are designed to provide proper germicidal ecacy for 16,000 hours.
• The UV lamps may continue to glow well beyond 16,000 hours but will not provide proper intensity and must be
replaced to ensure ecacy.
• The UV lamps are housed in a quartz tube. If the quartz tube becomes dirty, its ability to transmit UV rays from the
lamp will be diminished.
• The service interval for the quartz tube is dependent on pool water chemistry and some pools may require more
frequent cleaning than others.
• Initially, inspect the quartz tube after 750 hours of use and clean as needed. Subsequent cleaning intervals can be
increased or decreased based on the condition of the quartz tubes or observed water conditions.
