when does candle need cleaning?
Once the flow of water out of the filter becomes noticeably less than normal.
Brush the candle with a stiff brush under running water or in a bowl of water
Always brush away from the candle mount. Never use soap or detergents
After you have cleaned the candle place it into a container of water
and boil for 20 minutes
Allow to cool before placing the candle back into the filter
Boiling is not necessary for Sterasyl, Super Steralyl, Ulitfol 3 or Ultiflo 4 candles as these cancles are self-sterilising
When a new candle has been fitted into the filter,water should run to waste for approximately 10 minutes to prevent a slight earthy taste. With Super Sterasyl and Ultiflo 3 candles black dust may be seen in the waste water and we recommend running water to waste until clear
