REPLACING THE UV LAMP AND CLEANING QUARTZ DOME:
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 your
product warranty, electrical and CSA certification, and may result in any one or more of the following issues:
• Unsafe drinking water • Ballast failure • Electrical fire
Use of non-Rainfresh lamps will void all warranty & product certification
Genuine Rainfresh UV lamps can be identified as follows:
1.
Turn off supply valve before the unit and then unplug unit from electrical outlet and. Open a faucet to
depressurize the UV8B system and then turn off the valve at the outlet port to isolate it.
CAUTION:
The lamp end can be very hot. Wait several minutes for the lamp to cool down.
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.
4.
Carefully slide UV lamp slightly out of chamber and hold the lamp end with one hand. Gently pull off the
connector with your other hand to disconnect the lamp completely. Slowly remove 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.
6.
Remove & discard used dome "O" ring. Clean dome gently with a vinegar solution or a household scale-removal
product.
Do not use abrasive pads
. A soft cloth or paper towel is recommended.
7.
Using a small pointed tool carefully take the "O" ring out of the gland nut. Take care not to scratch the gland nut.
8.
A dome "O" ring (thicker) and gland nut "O" ring (thinner) are included with the
lamp. Slide gland nut "O" ring into the internal groove of the gland nut.
