System Sanitization
It is recommended to sanitize your system for general hygiene at least once a year when the pre-filters and the post filter
are to be changed.
Note :
This procedure involves some water spillage. Keep an absorbent towel handy to clean up. Use
sanitary rubber gloves for this procedure and read “warning” information on bleach container before using.

Shut off the cold water supply and drain the storage tank by turning on the RO faucet. Once this is completed
remove the pre-filters and membrane. Do not remove old post-filter at this point.
2.
Put 1/2 teaspoon of household bleach in 1/2 litre of water and fill the inlet filter sump, then replace both sumps
and reconnect membrane housing. Open supply valve and faucet and run water until you can smell chlorine
through the faucet. Add more bleach if necessary
3.
Close faucet and supply valve and allow the bleach to remain in the system for about 4 to 5 hours.
4.
After 4-5 hours open faucet and drain tank completely.
5.
Open supply valve and flush water out of faucet for a minute.
