Maintaining the osmosis system. The recommended maintenance of the ultrafiltra- tion system is in the table below. By not following the maintenance as described in this manual, using original HIDRO-WATER S.L cartridges and by authorized personnel that guarantees the quality of the water produced and the correct operation of the osmosis system, the warranty will be void.
6.1. PROCEDURE FOR REPLACING CARTRIDGES AND THE MEMBRANE a. Close the water supply brass ball valve (figure 5). b. Open the faucet (figure 2) to relieve the pressure from inside the osmosis sys- tem. c. To change any of the cartridges and/or membrane they must be turned clock- wise and pulled downwards to remove it from its cap as indicated in the follow- ing figure.
e. Once you have replaced one of the cartridges/membrane – with the faucet (Figure 2) open – open the brass ball valve (Figure 5) at the water supply. Let all of the air out from inside the ultrafiltration system. Once a continual water flow comes out of the faucet, let it run for 30 seconds and then close the fau- cet.
