Hardness < 7.0 gpg (120 ppm); Iron < 0.3 ppm; Manganese < 0.05 ppm; Turbidity < 10 NTU, Tannins/Colour: None; UV Transmissivity > 85%
If any of these parameters in your water are outside the limits, you may need additional filtration. Please contact Rainfresh for help.
REPLACEMENT UV LAMP
Rainfresh UV systems have one UV lamp that lasts 9,000 hours of use (approx 1 year), after which it must be replaced even though it may continue to light. This is because after 9,000 hours the ability of the UV lamp to kill bacteria drops below safe limits and can thus compromise your family’s health.
Use only GENUINE Rainfresh UV lamps : Use only GENUINE RAINFRESH UV Lamps with your UV system. Rainfresh UV lamps are designed with extensive product research and engineering to provide reliable and consistent UV output and performance that ensures the safety of your drinking water. Using non-Rainfresh UV lamps can not only compromise the system performance but also voids the electrical and CSA certification on the product and may result in unsafe drinking water, ballast failure or even an electrical fire. Use of non Rainfresh lamps will void warranty & product certification

A) UNDERSTANDING UV SYSTEMS
Q What does the Rainfresh UV System do? Will it clean up my water?
UV systems disinfect water by inactivating bacteria, coliform (such as E. coli), viruses etc. UVC light at a wavelength of 254nm disrupts the DNA of microorganisms preventing them from multiplying. This makes water safe to drink from virtually any potable source.
Q How does the Rainfresh UV system work?
The Rainfresh UV system consists of a low-pressure UV lamp enclosed in a transparent quartz dome, housed in a stainless steel disinfection chamber. As untreated water enters the chamber from one end, microorganisms like bacteria, viruses, cysts etc in the water are exposed to ultraviolet light being emitted by the UV lamp. The UV light kills/inactivates these microorganisms instantaneously and treated water flows out of the chamber and is ready for consumption.
Q) Does a UV system add anything to the water?
Rainfresh UV systems use chemical-free and environmentally responsible technology that does not require use of any chemicals. UV systems do not alter the water quality, other than disinfection.
Q) Can I drink the water after it has been treated by a UV.
Yes the UV system will make the water safe to drink from a microbiological safety point. You no longer will need to buy bottles and jugs to have safe drinking water in your home.
B) INSTALLATION, SIZING QUESTIONS
Q Can I install a UV system if I am on well, lake, cistern or river water?
Yes. Rainfresh UV systems are designed to be used on water from any source. However, tannin, organic colour etc can significantly reduce the efficiency of the UV system and may require additional pre-treatment. Send us a sample of your water (see link at the bottom of the page) for a free water quality report.
Q What kind of water quality is required for the UV system to work efficiently?
The unit should only be operated with water that meets the following minimum criteria:
Q How do I know what my water quality is?
You can send a sample of your water to our test lab for a no-charge analysis of your water. The link to details on how to send the sample is at the bottom of the UV information page. Our lab can test for hardness, iron, UV transmissivity, pH, Turbidity and Total Dissolved Solids
Q If I find that I need additional treatment such as softener or tannin filter, where can I buy that?
You can buy these at various retail outlets such as Home Hardware, Lowe’s etc. or order some of these systems directly from Rainfresh. Click on the “online store” link at the top of the page to order direct
Q Can I install the ACCUGARD UV before the pressure tank?
No. UV systems should always be installed as the LAST stage before water gets divided into hot and cold. Never install a UV before any storage tank.
Q Can I install the ACCUGARD UV horizontally?
No it is not recommended.
Q Should the ACCUGARD UV be installed before, or after, a water conditioner?
UV should be the last stage of treatment. It should always be AFTER any water conditioners.
Q Does the UV light consume a lot of energy?
No, the UV bulb included with the ACCUGARD UV system consumes less than 60 Watt power
Q Does the UV light stay ON all the time? Can I not turn it OFF when I don’t need water?
Yes the UV light stays ON all the time, even when you don’t need the water (e.g. during the night). Repeated ON/OFF actually shortens the UV lamp life. However, if you are going away from the house for a week or so, you can turn the UV system OFF. In this case first turn OFF the supply valve before the UV and then turn the UV off. Upon return, first turn the UV system ON, wait for about 10 minutes and then flush the water for a few minutes prior to consumption
Q Do I need a surge protector for my UV system?
Yes. You should never install the ACCUGARD UV without a surge protector. A CSA or UL certified surge protector rated for a clamping voltage of less than 400 Volts, response time of less than one nanosecond, and energy absorption of at least 1,000 Joules.
Q Can I plug in the ACCUGARD UV on the same circuit as my pump?
You should never install the UV on the same circuit as the pump as that can destroy the ballast. The UV should be installed on a dedicated circuit only.
C) MAINTENANCE QUESTIONS
Q Do I have to replace the UV lamp? Why?
The UV lamp degrades over time and after 9000 hours (approx 1 year) of use, its killing ability drops to levels that are considered unsafe. Therefore the UV lamp must be replaced once a year even though the UV lamp continues to lights up.
Q Can I use any generic UV lamp with the Rainfresh UV system?
No. Use only GENUINE RAINFRESH UV Lamps with your UV system. Rainfresh UV lamps are designed with extensive product research and engineering to provide reliable and consistent UV output and performance that ensures the safety of your drinking water. Using non-Rainfresh UV lamps can not only compromise the system performance but also voids the electrical and CSA certification on the product and may result in any one or more of the following issues:
Use of non Rainfresh lamps will void warranty & product certification
Q How do I know when to replace the lamp?
Rainfresh UV systems have a built-in alarm feature that signals end of lamp life by a flashing red LED and an intermittent beep. You can silence the alarm for 1 week three times to allow yourself time to purchase and install a new lamp. After that, the alarm cannot be shut off until the lamp is replaced.
Q Is there any other maintenance that is required?
You should routinely check the quartz dome and clean if scale has formed. The dome should also be replaced every 3 years. Also replace sediment filters regularly.
You should also replace the dome “O” rings whenever you replace the bulb (included with replacement UV bulbs).
Q Is there a need for me to test the water for bacteria now that I have a UV installed?
It is recommended that you continue to monitor your water safety through regular testing at least 2-3 times a year, even though you have a UV system.
D) TROUBLESHOOTING QUESTIONS
Q My UV system is beeping? What does that mean?
If the beeping is intermittent with the green LED ON and a flashing red LED, then it is a lamp-replacement alarm. You can silence this alarm for 7 days by pressing the black button on the ballast. Install a new lamp as soon as possible and reset the timer (instructions are included with the lamp).
Q I just replaced my lamp, but the beeping hasn’t stopped. What do I do?
You have not correctly reset the lamp timer. The lamp-change timer is reset by depressing the timer button
while reconnecting ballast to electrical outlet and keep the button depressed until the ballast emits a solid three-second beep. This will re-set the lamp-change-timer to zero and the 3-second beep will confirm that the re-set was successful.
NOTE : It is not possible to reset the lamp-change-timer unless the timer is in the grace period or lamp-change alarm mode or lamp-failure mode.
Q The UV is beeping, the UV lamp & green LED is OFF and red LED is ON. What’s wrong?
If the power to the UV goes beyond its operating limits, the ballast will shut down to protect itself from unsafe power. To correct the problem, simply unplug the unit, wait for 15 seconds and re-plug it.
Q I am getting a high-pitched squeal from the ballast and no light is ON. What is wrong?
Power surges may have destroyed the ballast. Contact customer service.
Q Why does the water seem hot first thing in the morning?
Sometimes over period of non-use the UV lamp heats up the water in the UV chamber. Simply flush a toilet first thing in the morning before using the water in the sink or showers.
E) MISCELLANEOUS QUESTIONS
Q Is the ACCUGARD UV system tested?
Rainfresh ACCUGARD UV systems is tested and certified by CSA Group to CSA B483.1 for material safety and structural integrity. It is also independently tested for microbiological inactivation and tested to deliver > 40mJ/cm2 UV dose at end of lamp life. This is higher than most other UV systems that rate their “kill dose” at only 30 mJ/cm2 or even less.
Q) Where is the Rainfresh ACCUGARD UV system made?
Rainfresh ACCUGARD UV system is made in Ontario, Canada.
