F. INSTALL STEM ADAPTER WITH 1/4” FEEDWATER
TUBE OUTLET
IMPORTANT NOTES
• For basement installations, the existing orange feed
water tubing may have to be longer to reach the faucet
adapter.
1) Open faucet and turn off cold water supply to relieve pres-
sure.
2) Locate the cold water stem on the underside of the faucet
fixture. Unscrew the cold water feed tube from the faucet
stem. Locate the Faucet Adapter that came with your drink-
ing water system. Insert the black gasket into the threaded
adapter and tighten onto the Faucet Cold Water Stem under
the sink, making sure that 1/4” side connection is accessible
and not facing the wall. Make sure not to overtighten.
3) Take the Cold Water Feed Tube and attach to the Faucet
Adapter, making sure not to over tighten.
4) Locate the 1/4” Orange Tubing and insert into the 1/4”
outlet of Faucet Adapter. See Figure 3 and “Using Push-in
Fittings” below.
5) Leave cold water supply off.
G. INSTALLATION SANITIZING*
PREFILL AND SANITIZE THE STORAGE TANK
To reduce the risk associated with eye, skin and respiratory and di-
gestive tract burns from Calcium Hypochlorite during installation:
•
Calcium Hypochlorite (CAS 7778-54-3) granules are
used for tank sanitation in this product.
•
During installation, do not get in eyes, on skin or
clothing. Do not ingest. Wear eye and face protection.
Keep out of reach of children.
•
To request an MSDS relating to this product, call 203-
238-8965 or visit the web at http://solutions.3m.com/
wps/portal/3M/en_US/MSDS (click MSDS search). For
emergencies, call 800-364-3577 or 651-737-6501 (24
hours).
To reduce the risk associated with ingestion of water contaminated
with sanitizer:
•
Sanitizer must be flushed from the system before
using as directed within the installation instructions.
Prefilling the storage tank is always recommended so that there
is pressure to check for leaks as well as sufficient water to flush
the carbon postfilter. The SQC RO Drinking Water Appliance
is furnished with a container of special sanitizing granules. It is
important to use a sanitizer when prefilling the tank.
1) Remove protective cover from storage tank and discard.
Locate the enclosed container of sanitizing granules, open
it and pour the contents into the end of the tank. Apply PTFE
tape (not included) to threaded tank connection and install
tank valve onto connection. Do not over tighten. Open the
tank valve so that the tank valve handle is parallel to the
valve body.
2) Disconnect the 3/8” yellow tubing from the back of the
filtration assembly and connect one end of it into the tube
fitting located on the tank valve.
3) Connect the other end of the 3/8” yellow tubing to the 3/8”
x 1/4” union connector included in the tank sanitization kit.
4) Connect the free end of the 1/4” orange feed water tubing
to the other end of the 3/8” x 1/4” union connector.
5) Open the cold water supply shut off valve (making sure the
tank valve is still open) and allow the tank to fill (about
3 minutes).
6) Close the cold water supply shut off valve and the tank valve.
Disconnect the 3/8” yellow tubing from the tank valve elbow
fitting and set the tank aside while proceeding with the rest of
the installation (the sanitizatizing solution should be kept in the
tank for at least 15 minutes).
7) Reconnect the 3/8” yellow tubing to the back of the
filtration assembly. Reconnect the 1/4” orange tubing to
the feed water fitting on the filtration assembly.
IMPORTANT NOTES
• If you encounter difficulty in removing the tubing from the
tank, make sure the tank valve is closed and then cut the
yellow tubing approximately 1” away from the tank valve
fitting to relieve the pressure. Remove the 1” piece from
the tank fitting.
• If an alternate storage tank is used, it should be sanitized
with household bleach (5-1/4%). Use 3 ml. (1/2 teaspoon)
of bleach for a 2.5 gallon tank.
• After the installation is complete, it is recommended that
the 3/8” x 1/4” union connector be saved for future use in
tank sanitization.
