Rainfresh R519 Replacement

Cautions:
1. Do not plug the unit in if any electrical surfaces or electrical parts are wet.
2. Before any cleaning or maintenance on the system, always unplug the unit from the power source. Disconnect plug from
the power outlet by holding the plug. Never pull the cord.
3. Do not look directly at the UV Lamp when it is ON. UV light can cause serious burns to unprotected eyes and skin. Do not operate
the UV lamp outside the UV chamber.
4. The UV Lamp and quartz dome are fragile. Handle them with care and caution.
5. 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.
6. Do not attempt to replace dome "O" ring without taking the dome out of the chamber.
Lamp Replacement & Dome Cleaning / Replacement Procedure
The UV lamp has an effective life of 9000 hours of continuous operation, after which it should be replaced regardless of its apparent condi-
tion. As a good maintenance procedure it is recommended that the quartz dome also be cleaned at the time of lamp replacement. Note:
Some water conditions may require more frequent cleaning of the quartz dome.
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).
3. Loosen the black screw on the lamp
connector cover and remove cover from
the gland nut.
6. Remove and discard used dome "O" ring. Clean the exterior of the dome gently with a vinegar solution or household scale-removal
products. Caution: Make sure that the dome stays dry on the inside.
7. Using a soft pointed tool carefully take the gland-nut "O" ring out of the gland nut. Take care not to scratch/gouge the glandnut.
8. A dome "O" ring (thicker) and gland nut "O" ring (thinner) are included with the replacement lamp. Slide gland nut "O" ring into the
internal groove of the gland nut.
9. Replace dome "O" ring on to quartz dome
about 1" from the open end.

4. Carefully slide UV lamp slightly out of chamber and hold the lamp end with
one hand. CAUTION: The lamp end can be very hot. Gently pull off the con-

lamp from the disinfection chamber completely.
5. Remove the quartz dome by loosening the gland nut and carefully extracting from
the unit. 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.
