I do not see any flow or temp detection on this? I seen the warning in instructions about water flow requirement, but I also know that fused quartz has a very great thermal shock resistance (1k°C+). I also researched UV lamp (I assume your product uses low pressure mercury arc?) which likes to operate around 100°C. Are your instructions implying the quartz you use, cannot tolerate lamp temp to cold water temp change, if I were to put a flow controlled power cut switch on it?
