CARBON BLOCK FILTER REPLACEMENT:
A Carbon Filter will usually lasts 4-6 months, depending on the micron
rating for the filters, usage and the chlorine content of your tap water.
The best way to determine when your Carbon Block Prefilter needs
replacement is to use a chlorine test kit.
Any chlorine level above 0.1 ppm will cause damage to the membrane
and indicates that the carbon block filter must be changed. To test for
chlorine breakthrough, collect a 10 ml sample of the concentrate from
the yellow tubing and test the chlorine concentration using test kit TK-CL-
10-KIT. If the chlorine concentration is above 0.1ppm, replace the carbon
prefilter.
**NOTE: A drop in the system’s production is, in most cases, an indication
that the sediment filter has become saturated with contaminants, but a
carbon filter can also decrease production if it’s covered with extremely
fine sediment. If the carbon becomes plugged with sediment, it will no
longer be able to remove chlorine.
Carbon Block Filter Replacement
Materials Required:
0.5 micron Carbon Block prefilter (CF-0.5 -10),
Filter Wrench, Chlorine Test Kit (TK-CL-10 -KIT)
Procedure:
1. Turn off water supply to the system.
2. Using the provided filter housing wrench, remove the second housing
from the left. Unscrew it counterclockwise as viewed from the bottom.
3. Remove the old filter and discard.
4. Thoroughly wash the housing with a mixture of hot soapy water and a
few teaspoons of household bleach. Rinse well with clean hot water.
5. Insert the new carbon block filter into the housing, making sure that
the black gaskets on bothends of the filter are firmly seated in the
gasket recesses.
6. Screw the housing back onto the assembly and hand-tighten
only
.
NOTE: Do not use filter wrench to tighten housings. Over-tightening
will damage housings and void your warranty.
7. Turn on system water supply and check for leaks.
