CAUTION!!
For your safety and protection, do
not use where water is microbiologically unsafe
or of unknown quality. The water supply to your
system MUST be from the COLD WATER LINE!
Hot water will severely damage your reverse
osmosis system!
Note
: In some cases, the supply valve may leak
or may not work at all. If this happens, turn off
the water at the main water shut off for the entire
house. In extreme cases, the house shut off
valve does not work. If this happens, shut the
water off at the street and replace the defective
valves immediately.
Locate the type of shut off valve you have under
your sink and follow that step for connecting the
feedwater.
1.
Turn off cold water supply to the sink using
the supply valve located under the sink.
2.
Some shut off valves have an extra port for
an icemaker hookup. You will not need the
feed water adapter for this type of installation.
See Diagram C.
3.
On some shut off valves, you can install the
feed water adapter directly to the valve. Slip
the black washer into the feedwater adapter.
Tighten feedwater adapter to the valve with
an adjustable wrench. Tighten until snug.
Insert the 1/4” brass straight fitting into the
feed water adapter. TIGHTEN BY HAND
ONLY! DO NOT OVERTIGHTEN!
See Diagram D
.
4.
Most under sink shut off valves have a built in
smooth or corrugated riser going up to the
faucet. Refer to Diagram E for help with this
type of valve
.
Secure an adjustable wrench to
the fitting on the cold water side of the sink
faucet – NOT THE REVERSE OSMOSIS
FAUCET! Secure another adjustable wrench
to the smooth /corrugated riser line nut.
Gently undo the riser line from the sink
faucet. Do not be alarmed! There will be
water left in the line—this is normal.
However, if the flow does not stop you
probably haven’t shut the water off properly.
(See the Note in Step # 1, Section # 3 if you
need help with water shut off.)
5. Insert the black rubber washer into the
feedwater adapter. Screw the adapter onto
the fitting coming from the cold water side of
the sink faucet. Using two adjustable
wrenches, tighten the feedwater adapter to
the cold water line. Take extreme care not to
twist or damage the connection to the cold
water connection.
CAUTION!!
Tightening the connector
improperly to the faucet could cause
irreparable damage to the faucet.
6. Connect the riser from the water shut off
valve to the feedwater adapter. Ensure that
the cone washer on the riser tube is in good
condition. With one adjustable wrench on the
feedwater adapter and another adjustable
wrench on the riser nut, connect the riser to
the feed water adapter.
DO NOT OVER TIGHTEN! This can cause
damage to the riser connection.
7. Insert the 1/4” brass straight fitting into the
feed water adapter. TIGHTEN BY HAND
ONLY! DO NOT OVERTIGHTEN!
If you have a self-piercer assembly, skip to step # 8.
