*** Service life depends on quality of feed water.
1 Without disconnecng the system from the mains, turn o the water supply valve on the
system, turn the tank ball valve to the "Closed" posion.
For systems with a puried water faucet: open the tap on the sink, turn o the water supply
valve on the system, turn the tank ball valve to the "Closed" posion.
For systems without a faucet, open the tap for supplying puried water to the consumer.
2 Wash your hands with anbacterial soap thoroughly.
3 Aer water has stopped running from puried water faucet, unplug the RO system from the
mains and screw o the three lter housings. Take care as the bowls will be full of water. In
the Robust 4000 system, you need to remove the right side panel.
4 Remove spent lters.
5 Wash the bowls thoroughly with non-aromac soap, and then rinse with water.
6 Install new lters in bowls in the correct sequence from le to right:
polypropylene, GAC, carbon block (for systems RObust Mini, 1500, Pro), two acvated carbon
lters (for RObust 3000), polypropylene, GAC (for RObust 3000MAX), or polypropylene and
carbon block (for RObust 4000).
For the RObustPro system also insert a special RObustPro replacement lter.
Rinse it by pulling out the tube with ow restrictor aer lter.
7 Start rinsing pre–lters: open a special rinse valve and pass the required volume of water to
the bucket unl there are no carbon nes in rinsewater.
