Ultraviolet Systems for Pools FAQ
Ultraviolet Installation Questions
UV System Service Questions
A. As pool water is circulated through the wet reactor chamber of the Ultra UV system, one or more UV-C germicidal lamps contained in the reactor(s) expose the pool water containing bacteria, viruses, algae spores, pathogens and microorganisms, to the high intensity light waves emitted by the UV-C lamp(s). This causes the DNA of these pathogens to be disrupted and unable to multiply. Without the ability to multiply, these pathogens die and are rendered harmless. It is easy to understand that bacteria laden water enters the reactor, and drinking quality water leaves the reactor back to the pool. Consult the Technical link for a more technical explanation of this process. (Note: While drinking quality water exits the Ultra UV pool sanitizer, it is not intended for use in sanitizing drinking water and should not be used as such. Drinking water sanitizers have different technical requirements (alarms, etc) then do swimming pool UV systems).
A. A UV system for a swimming pool is sized to match up with the water flow of the pool circulation pump(s). Consult the Ultra UV Owner’s Manual to see which model Ultra UV system matches the flow rate of a specific circulation pump. Information accompanying the pump can provide this flow rate, as can the pump supplier’s literature or website, or the dealer or installer that provided the pump. And, remember that the Ultra UV pool sanitizer is convertible to allow for increasing the killing power of the UV system if a system was selected originally that was undersized due to under estimating the pool’s circulation pump output rate of flow.
A. As noted in the first question and answer, the Ultra UV pool sanitizer treats the water as it passes through the reactor chamber of the system. When organic materials, such as skin scrapings, urine, sweat, bird droppings, dust etc. enter the pool, there must be a low level of sanitizer present to treat the pool water until it reaches the UV reactor. Owners of UV systems report sanitizing chemical reductions of 50%-70% in many cases. Chemicals for control of pH, and other chemicals the pool owner may have used prior to the installation of their UV system should still be followed, as the Ultra UV system imparts nothing into the pool water when killing bacteria in the pool water. This is a real plus over alternate sanitizing methods that add chemicals to the pool water during the sanitization process.
A. One of the side benefits of the Ultra UV system is its ability to reduce or eliminate mono-chloramine in the pool water. Chloramines are the by-products of chlorination and are the “chlorine smelly” odor associated with chlorinated pools. With proper Ultra UV sizing and chemical maintenance, the chloramine “chlorine” odor can be eliminated and the pool returned to a safe and enjoyable environment.
A. The Ultra UV pool samitizer installs in the circulation system, after the filter and before any heater or chemical injection points. Designed to accommodate 3 different pump output flow rate ranges up to 130 GPM (40.4 m3/hr), installing the Ultra UV system is a simple and low cost procedure for the pool builder or homeowner. Consult the Ultra Owner’s Manual for detailed installation instructions.
A. Another one of the big advantages to the Ultra UV pool sanitizer is its low power draw and resulting low operating cost. Even an Ultra UV system with 3 lamps draws less power than a 200W bulb. All Ultra UV systems are cord connected (subject to the requirements of the jurisdiction where the unit is being installed) Plugs used in most countries are normally available.
A. All Ultra UV systems are available in either 120V/50/60 Hz or 230V/50/60Hz electrical power.. Note: Do not operate the Ultra UV system on any power not indicated on the silver service plate on the front of the unit. These systems are NOT dual voltage. The pool owner should contact the supplier if the voltage indicated on the Ultra UV unit’s service label does not match the available power source.
A. One of the key features of the Ultra UV pool sanitizer is its ability to be upgraded by adding one of more (up to a total of 3) additional UV lamps to the system. This way, the pool owner who has not accurately calculated the output of their pool pump and finds the system they chose to be undersized, it is a simple matter of obtaining an upgrade kit from their supplier and making the upgrade right at the installation, in a matter of minutes. This unique feature also allows the pool owner’s Ultra UV supplier to provide the full range of Ultra UV systems from inventory, simply by upgrading a unit they have in stock to the desired unit, without waiting for the desired unit to arrive from Ultraviolet Pools.
A. Yes. The Ultra UV system contains a pressure sensing switch that senses when the circulation pump goes OFF. When this is sensed, the switch turns the UV system OFF and then back on when the pump comes ON, all automatically. No interlocking of the Ultra UV system to the circulation pump is required. Note: In installations where the Ultra UV system is located below the pool’s water level, the UV system is full of water all the time and the built-in bypass mechanism of the pressure switch should be employed, as noted in the Ultra UV Owner’s Manual.
A. Aside from a periodic cleaning of the quartz tube(s) and scheduled lamp replacement (easily accomplished by the homeowner), no other maintenance of the Series 2 system is required. Consult the Ultra UV Owner’s Manual for full specifics.
A. All Ultra UV systems incorporate low pressure, high output, long life (LPHOLL) UV-C lamps. All Ultra UV lamps are rated at 13,000 hours (or 18 months) of useful life. The pool owner should not be confused by the fact that a lamp is still glowing after this useful life, as a lamp looses its killing power at the lamp End-Of-Life (EOL) and should be replaced to bring the Ultra UV pool sanitizer unit back to its design output.
A. The pool owner’s first resource for replacement parts is their supplier. If the supplier is unable to provide warranty or non-warranty parts, the pool owner should contact Ultraviolet Pools in any of the methods shown in any of the Contact Us links of this website, and Ultraviolet Pools will be pleased to assist them.
A. All questions concerning the Ultra UV system should be directed to your supplier first. If the supplier is unable to answer your questions, by all means contact Ultraviolet Pools by any of the methods indicated in any of the Contact Us links on this website. Ultraviolet Pools will be pleased to answer any product, technical, or general questions in the shortest time possible. Questions not involving the UV unit or regarding pond operation should be directed to the pond supplier who is an expert in those areas.
A. Due to the high quality of each component and the system itself, Ultraviolet Pools is proud to offer one of the industries most generous warranties on its Ultra UV system. Consult the Ultra UV Limited Warranty for specific details.
A. Yes. Unlike other warranties that only cover part of the lamp life, Ultraviolet Pools covers the lamp for the full 13,000 hour useful life, as stated in the Ultra UV Limited Warranty.
A. The Ultra UV pool sanitizer is made from polymeric materials throughout and is compatible with pools equipped with salt chlorine generators. Due to the bacteria killing capability of the UV system, the pool owner need not generate as much chlorine as would be required without a UV system, so the salt level in the pool can be reduced and the chlorine generation setting can be lowered. A little trial and error will show the pool owner what salt generator settings are best for their pool. Note: If the pool is operated with Sea water, contact your Ultraviolet Pools supplier or Ultraviolet Pools for information regarding selection of the proper UV system for Salt Water application.
A. The Ultra UV system has been designed to operate in both an indoor and outdoor environment, and is fully protected from the elements. With a 100% polymeric exterior, no chance of rust or corrosion is present. However, to keep the system looking new over its life, some protection from adverse weather (sun, rain) is recommended. Note: The UV system must not be allowed to freeze. Damage to the internal components, accessories, or even breakage of the reactor vessel itself can occur, and this is not covered under the Limited Warranty.
