Rainfresh R1245 Installation & Maintenance Instructions Manual

INTRODUCTION
Rainfresh water disinfection systems utilize the proven properties of ultraviolet light (UV). UV emitted at 254 nm wavelength kills/inactivates
harmful bacteria (i.e. coliforms, fecal coliforms & E.Coli), viruses, fungi, algae, spores and other microorganisms in water. UV purifi cation is a
natural, non-chemical, environmentally safe technique which does not form any harmful disinfection by-products.
HOW YOUR UV DISINFECTION WORKS
Your 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, fungi, algae etc in the
water are exposed to ultraviolet light being emitted by the UV lamp. The UV light kills/
inactivates these microorganisms and treated water fl ows out of the chamber and is ready
for consumption. See Fig. 1
SAFETY INSTRUCTIONS
• To avoid possible electric shock, extra care should be taken since water may be
present near electrical equipment. Unless specifi cally referred to in these instructions,
do not attempt repairs yourself. Contact the manufacturer for service advice.
• Do not plug the unit in if any electrical surfaces or electrical parts are wet.
• DO NOT LOOK DIRECTLY AT UV LAMP WHEN LAMP IS ON. UV light can cause serious
burns to unprotected eyes and skin.
• Do not operate the UV lamp outside the UV disinfection chamber.
• Do not use this unit for any purpose other than its intended use for potable water
disinfection. The use of attachments not recommended, approved or sold by the
manufacturer may result in improper performance of the unit or an unsafe condition.
• Do not operate the system if it has a damaged electrical cord or plug, is
malfunctioning, or has been damaged in any way.
• Do not touch the lamp or quartz dome with dirty or moist hands. Hold the lamp and dome by the ends with soft dry gloves or cloth.
• Before any cleaning or maintenance on the system, always unplug the unit from the power source. Disconnect from the power outlet by
holding the plug. Never pull the cord.
• You must connect your UV unit to a grounded (3-pronged) receptacle (a GFI is preferred) and ensure that the lamp connector ground
wire is connected to the stainless steel end of the main chamber. Use of extension cords is not recommended.
• Installation of the UV disinfection system and water fi lter will interrupt electrical grounding continuity of your plumbing system.
For directions on restoring the electrical grounding continuity, consult your local electrical inspector.
• Power source for applications outside North America must match requirements of the unit (For example 220V, 50Hz or other).
• Protect your unit from freezing. Drain all water from the unit if freezing temperatures exist.
After 1 year of use, it will no longer provide eff ective disinfection even though it stays lit.
USE ONLY GENUINE RAINFRESH UV LAMPS. Use of non-Rainfresh UV lamps can result in unsafe drinking water
BEFORE YOU INSTALL THE SYSTEM
The unit should only be operated with water that meets the following minimum criteria:
• Turbidity/Suspended Solids: Less than 5 PPM (mg/L). Ideally less than 1 NTU (Nephelometric Turbidity Unit). A 5 micron sediment
fi lter should be installed before the UV system at all times. We recommend Rainfresh Model FC150 (5 micron sediment fi lter and
housing assembly) If the feed water has fi ne sediment, a fi ner pre-fi lter (1 micron or smaller) may be used. If the water has very high
turbidity, a backwashable multi-media fi lter is recommended.
• Hardness: Less than 7 gpg (120 mg/L). Hard water causes scale build-up on the quartz sleeves thereby reducing the UV transmittance
in the water and in turn reduced performance. For high hardness water, a water softener should be installed prior to the UV system.
• Iron & Manganese: Iron less than 0.3 PPM (mg/L) and Manganese (less than 0.05 mg/L) is desirable. At higher concentrations, a suit
able water conditioner (e.g a greensand fi lter) should be installed prior to the UV system to prevent iron build-up on the quartz dome.
• Tannins and Colour: Water with tannins or colour has low UV transmissivity that reduces UV system performance. A tannin-removal /
colour-removal activated carbon system should be installed to improve UV performance.
