Next, unscrew the two blue compression fittings located at either end of the white plastic body and slide off the 'O'
rings. Then slide out the quartz sleeve. Clean the sleeve and polish with a soft cloth or paper towel.
If you live in a hard water area there may be some lime scale on the quartz sleeve. This can be easily removed by
soaking the sleeve in a proprietary kettle de scaling solution (follow the manufacturer's instructions). Failure to
remove the lime scale will limit the effectiveness of the UV lamp.
• Slide the clean, dry quartz sleeve into the unit. Ensure that you locate the 'O' rings carefully on the ends of the
quartz. Failure to do so will result in leaks when the water is turned on.
• If you are carrying out the annual lamp change, use new 'O' rings.
• When you re-assemble the unit, ensure that the female threads on the compression fittings and the male
threads on the main body are clean.
• Wipe a little silicon grease or Vaseline (NOT silicon sealant) onto these threads. As these threads are only ser-
viced periodically, this lubrication will help to prevent them binding together.
• Then replace and firmly hand tighten the compression fittings.
• Replace the lamp or fit a new one.
• Relocate the lamp holders and blue lamp holder shrouds ensuring that you match the correct numbered lamp
holders.
NOTE: Pinch the blue lamp holder shroud as you reassemble the unit to release any trapped air. Failure to release
the trapped air may cause the lamp holder to disconnect from the lamp end.
• Reconnect and turn on the water supply to check for leaks before reconnecting the electric supply.
IMPORTANT: The plastic body and blue compression fittings have been manufactured from polymers that
have been specifically stabilised to protect them from the effects of the UVC emitted from the UV lamp.
Despite this UV protection they will be eroded by a combination of the UVC and water flow.
As a matter of course they should be inspected whenever a lamp change is carried out, to ensure they are
not showing excessive wear and tear.
