INSTALLATION (continued)
Sanitizing the System and Lines
The plumbing must be sanitized to eliminate possible
contamination that may have occurred during the instal-
lation process.
One ounce (30 ml) of liquid chlorine bleach (regular
bleach, unscented 5.25 % - 6 % sodium hypochlo-
rite) or Kay-5 sanitizer solution (Sodium Dichloro-s-
Triazinetrione Dihydrate, 6%) or equivalent can be used
to sanitize the plumbing.
The Kay-5 sanitizer solution is made by dissolving a
1 oz. packet of Kay-5 powder in 2 oz. (60 ml) of clean
warm water. This can be done by removing 1 inch from
the top of the Kay-5 packet and adding the 2 oz. of
warm water to the packet. Mix with a coffee stirrer to
dissolve. When added to the system, this will create a
60-100 ppm chlorine solution.
NOTE: Follow the handling and safety instructions
supplied with the sanitizer.
1. Follow the steps in the
Rinsing the Ultra Filter
Cartridge in the Installation section of this manu-
al.
2. Turn off the water to the system.
3. Open the faucet or tap closest downstream to the
system.
4. Close the Inlet Water Valve and allow the system
to depressurize.
5. 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.
6. Press the FLUSH button to help drain the system.
7. 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 sanitizer onto clothing or skin. You may
want to add the sanitizer using a cup. Reattach
the cap on the fitting.
8. Slowly open the inlet water valve and allow water
to flow out of the tap until the smell of sanitizer is
present.
CAUTION
Ingesting the protective solution may cause irrita-
tion of the gastrointestinal tract, colic, diarrhea, or
other similar symptoms
IMPORTANT
Commonwealth of Massachusetts Plumbing Code
248 CMR shall be adhered to. The use of saddle
valves are not permitted, please consult your
local plumber.
9. Immediately close the tap and let the system
stand with no water flow for at least 15 minutes to
allow the sanitizer to sanitize the pipes.
10. After 15 minutes without water flow, open the tap
and flush until the presence of sanitizer is gone.
All other taps should be opened to flush any
bleach from the plumbing. Close the taps.
11. Press the FLUSH button to complete the flushing
process.
