Frequently Asked Questions
Here you will find many of the most frequently asked questions (FAQ's) about Delta UV systems for specific applications. Just Hover over the question with your mouse and read the answer to the questions on the right. Click on the catagories on the right.
Q: What Considerations Should Be Made For Salt Water Installation?
A: In addition, if the installation is very near a salt water body (ocean etc), the salt spray and the normal salt water environment found will be tough on the stainless steel exterior of all units, except the E series, even though the water being sanitized is fresh water.
Q: What Is The Maximum PSI (Bar) Operating Pressure Allowed?
A: All Delta UV Systems are rated at 40 PSI ( 3 Bar) operation range. All Systems have a very minimum head loss through the unit, usually less than 1 PSI (.34 Bar)
Q: Can The UV System Be Operated Continuously?
A: Yes, all Delta UV systems are designed to allow for continuous use. The High Output UV lamp in all Delta UV Series systems are rated at 9000 hours (one year) of continuous use. It is important to change the bulb after 9000 hours, as the output of the bulb is no longer capable of providing proper bacteria kill after 9000 hours as it has reached its useful end-of-life (EOL).
Q: Can Tue UV System Be Installed Below The Water Level Of The Water Feature?
A: Yes. All systems except the EA Series have a built-in pressure sensor to shut the system down if the pump stops (as in time clock operation of the circulation pump). When installing a unit below waterline, some adjustment of the pressure switch may be required. Consult the applicable Series Owner Manual in the DOCUMENTS section of the CUSTOMER CARE link for information on installation below waterline. Once the pressure sensor issue is addressed, all Series units will function below waterline the same as they would if installed above waterline.
Q: Which Series Should Be Used On Water Features?
A: The decision on which Series to use depends upon the physical space available for the unit, and the flow rate of the water through the UV unit. If Salt Water is used in the water feature, then the E Series is recommended as it is 100% PVC construction and is not subject to metallic corrosion as no metal is used.
Q: Can The EA Series Be Submersed In The Water?
A: Yes! The EA pumps are fully submersible.
