Section three
Maintenance
When you have assembled the filter as shown the only maintenance required is the periodic
cleaning of the filter candles. To clean the filter candles we would suggest the following
procedure.
1. Remove the candle/s (4) from the upper section (3) by unscrewing the wing nut (6) making
sure you keep the washer (5) in a safe place for refitting later.
2. Hold the filter candle under running water or in a bowl of water and clean the ceramic
portion of the candle with a stiff brush ensuring that no water or contamination is allowed
to enter the out-let hole in the threaded portion of the candle mount. Always brush the candle
in the direction away from the candle mount.
DO NOT USE SOAP, DETERGENTS OR BLEACH WHEN CLEANING THE FILTER CANDLE.
We suggest that the filter candles are replaced at 12 monthly intervals.
Warning:
In some cases the Cartridge media can become lodged at one end. Upon contact with
water this media will expand and can split the cartridge. To prevent this, shake cartridge
horizontally before use
Sanitising the system
1. Place 3 ‘Puritabs’ disinfecting tablets in the upper housing with the cartridge(s)
2. Fill the system with water.
3. Allow to stand for 40 minutes.
4. Now empty the upper housing.
Going on holiday
If you go away for a holiday or are away for a few days, it is recommended practice to turn off the
household mains water, whether or not you have a ItDoesTheJob.com system. When you return,
fill the system with water and let it flush through the Cartridges to ensure your next batch of water
will be pure and fresh.
If you are taking your Gravity Filter with you on holiday it is advisable to take spare cartridges in
case of any breakages.
