CARBON BLOCK FILTER REPLACEMENT:
A Carbon Filter will usually last 4-6 months ,depending on the chlorine (or
chloramine) content of your tap water and quantity of water being pro-
duced. 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:
5 micron Carbon Block Filter (IL-CB-12),
Chlorine Test Kit (TK-CL-10-KIT)
Procedure:
1. Turn off water supply to the system.
2. Disconnect the two black tubes, remove the old filter and discard.
