   FAQ

  • 1. Should I replace my lamps every year even if the lamp output is still good after 9000hrs?

    Yes, after 9000 hours of use; low pressure high output (LPHO) lamps will use most of the useful gasses is the lamps and even though the output may be fine it can change without any sudden warning.

    After 9000 hours of use, LPHO lamps will burn most of the tungsten off of the filaments, these lamps then require more energy to keep them illuminated. Not only do the lamps become less efficient, it can also cause damage to the ballast.

  • 2. My unit is giving us a water quality alarm even though the water is perfectly clear, is this a problem with the unit?

    Every unit is designed to alarm when the UVT (Ultra violet transmittance) drops below its minimum suggest level. (Either 50 or 75%). If the UVT drops below that level the system is designed to alarm

    Even water that looks perfectly clear can have a low UVT%

    If the sensor, quartz sleeve and reflectors on the UV are in good working order; have the water tested for UVT to confirm if the pre-treatment requires an upgrade.

  • 3. I am currently installing a UV Pure UV system but we currently have PVC piping is this ok?

    No, due to the water temperatures that can be produced from the UV system, Do not use PVC pipe or braided hose at the outlet – during extended periods of no flow, water temperatures may exceed softening point of PVC if unit fails to purge. Metal pipe or high temperature plastic pipe such as PEX, should be used after the flexible hose. Make sure the sealing washer is inside the end of the hose before making the connection. Do not bend the flexible hose excessively.

    There should be at least a 4 foot run before piping into existing PVC.

  • 4. Can I mount the units horizontally?

    No, due to the lamp design and the cooling characteristics of our systems, they should be mounted in a vertical position.

  • 5. I Purchased a set of lamps from an online vender, the top ceramics do not say UV Pure, are they safe to use?

    We do not recommend using parts other than original UV Pure OEM parts, no other parts have been tested or approved with our units. Aftermarket parts may cause adverse performance from your unit or even component failure. The use of Aftermarket parts (Non-OEM) will void any warranties with your unit.
