A) SAFETY INSTRUCTIONS
o To avoid possible electric shock, extra care should be taken since water may be present near electrical
equipment. Unless specifically referred to in these instructions, do not attempt repairs yourself. Do not plug
the unit in if any electrical surfaces or electrical parts are wet.
o DO NOT LOOK DIRECTLY AT UV LAMP WHEN LAMP IS ON. UV light can cause serious burns to eyes / skin.
o Do not operate the UV lamp outside the UV disinfection chamber.
o Do not operate the system if it has a damaged electrical cord or plug, is malfunctioning, or has been
damaged in any way.
o Do not touch the lamp or quartz dome with bare hands. Hold the lamp and dome by the ends with soft dry gloves or cloth.
o Before any cleaning or maintenance on the system, always unplug the unit from the power source.
o Disconnect power cable from the power outlet by holding the plug. Never pull the cord.
o
To ensure continuous protection, UV LAMP MUST BE REPLACED ANNUALLY. After 1 year of use, it will no longer provide
effective disinfection even though it stays lit.
o
Over time, the quartz dome starts to block UV light even though it may appear clean. Therefore the quartz dome should be
replaced after 3 years of use regardless of its condition. A stained, scaled or discoloured dome that cannot be cleaned should be
replaced immediately.
Use of non-Rainfresh products can result in unsafe drinking water and will void your product warranty.
B) UV LAMP AND QUARTZ DOME REPLACEMENT PROCEDURE
1. Turn off supply valve before the unit & open a faucet to depressurize the UV system. Turn off the valve at the UV outlet to
isolate UV unit. Now unplug UV unit from electrical outlet and wait for a few minutes to allow the lamp to cool.
2. Unscrew
the ground
nut and
remove the
ground wire
(green wire
with yellow
stripes).
7. If you are replacing UV lamp only and not the quartz dome, clean the exterior of the dome gently with a vinegar solution or
household scale-removal products.
USE ONLY GENUINE RAINFRESH UV LAMPS & QUARTZ DOMES.
5. Remove the quartz dome by loosening the gland
nut and carefully extracting from the unit. For
R1245 UV units, unscrew and remove bottom gland
nut first. Remove dome absolutely vertically from
its position until the other end comes out.
Caution: If you bend the dome mid-way, it can
break easily and pieces of quartz can fall into the
UV chamber.
Do not lose the spring that is inside the dome.
Caution: Make sure that the dome stays dry on the inside.
