The plumbing must be sanitized to eliminate possible
contamination that may have occurred during the instal-
lation process. Chlorine bleach can be used to sanitize
the plumbing. The amount of bleach to use depends on
the system installed and the amount of plumbing down-
stream of the filter system. Generally, one ounce (30
ml) of bleach will be sufficient to sanitize the system.
1. Make sure that the system has been flushed of
air and debris as described in the Flushing and
Starting up the System section of this manual.
2. open the tap closest downstream to the filter sys-
tem.
3. Close the inlet water valve and allow the system
to depressurize.
4. Place a bucket under the “T” or cross fitting at
the inlet connection to the system. open the inlet
drain valve or unscrew the cap to drain the sys-
tem.
5. Press and hold the Program button to help drain
the system.
6. When the water flow out of the inlet fitting stops,
close the inlet drain valve and pour the liquid
bleach into the inlet connection fitting. Be careful
not to spill bleach onto clothing or skin. You may
want to add the bleach using a cup. Reattach the
cap on the fitting.
6. Slowly open the inlet water valve and allow water
to flow out of the tap until the smell of bleach is
present.
7. Close the tap and let the system stand with no
water flow for at least 15 minutes to allow the
bleach to sanitize the pipes.
8. After 15 minutes without water flow, open the tap
and flush until the presence of bleach is gone. All
other taps should be opened to flush any bleach
from the plumbing. Close the taps.
9. Press and hold the Program button for at least 60
seconds to complete the flushing process.
10. Sanitation is complete.
Program the timer following the procedure outlined in
the operation section of this manual.
