REPLACEMENT OF THE PREFILTER, POSTFILTER, AND RO MEMBRANE
ELEMENTS
1. Turn off the water supply to the RO System.
2. Reduce system water pressure by opening the faucet.
3. Disconnect locking bar and place the fittings (with tubing still
connected) into a tub or bucket.
4. Move system into a contained area, such as a sink or tub.
5. Remove the support leg from the three sumps and unscrew the top
sump as shown to access the prefilter element. The support leg
functions as a wrench to loosen the sump, Figure 7.
Figure 7
CAUTION:
Even with the water supply turned off the membrane
and prefilter sumps will contain a considerable amount of water. By
positioning the RO assembly in a sink or tub, most of the water will
be contained.
NOTE:
There is no need to disconnect tubing from fittings on the
manifold. Remove locking bar and pull fittings out. Lubricate O-rings
with silicone prior to re-assembly.
NOTE:
If changing only the prefilter and postfilter, the other sumps
do not need to be removed.
If changing the membrane elements, the prefilter and postfilter
should also be changed.
