*The life of the filters and membranes will vary depending on the quality of the water supply,
the usage and the amount of impurities it has.
**The duration of the membrane will be approximately 2 – 3 years given that mains water's
conductivity is equal to or inferior to 1000ppm and the hardness is between 0 – 15ºF. If the water
supply's characteristics, if applicable, are different, then the conditions regarding the replacement of
the membranes will change.
Replace the cartridges in the given period to ensure the life of the membrane and the quality
of the water obtained.
6.1.- Procedure for replacing cartridges and the membrane
a. Close the water supply brass ball valve (Figure-14) and unplug the system from the electricity
supply (only systems with a pump).
b. Close the storage tank ball valve (Figure-15).
c. Open the faucet (Figure-8) to relieve the pressure from inside the osmosis system.

g. Remove the postfilter from its original packaging, remove the protective plugs on each end
and place the new postfilter on its corresponding plugs, paying attention to the arrows on
the postfilter which indicate the water flow. Make sure the postfilter is fitted the right way
because otherwise the water won't flow correctly.
h. Apply sufficient Teflon to the threads of the "T" and elbow piece that we took off the postfilter
and screw them back on the new filter. The "T" should be screwed on the input to the
postfilter and the elbow piece to the output. Insert the corresponding tubes and screw on
the corresponding nuts.

Once you have changed one of the cartridges, turn off the faucet (Figure-8), open the
storage tank ball valve (Figure-15), open the water supply brass valve (Figure-14), plug the
system into the electricity supply and check that there is no water leaks. If there is close the
valves and fix it.
Precaution 1: If there is any leak on the connection part of the tube, take it off and cut off 0.5
cm. Then reconnect it. If there is a leak coming from a thread, unscrew the piece, apply more Teflon
and screw it back on again.
