Hardness:
Recommended hardness not to exceed 10 grains per
gallon, or 170ppm . System will operate with hardness over 10 grains
but the membrane life may be shortened . Addition of a water soft-
ener may lengthen the membrane life .
Water Pressure:
The operating water pressure in your home should
be tested over a 24-hour period to attain the maximum pressure .
If the incoming water pressure is above 85psi, a pressure regula-
tor is recommended and if over 100psi, then a pressure regulator is
required .
Copper Tubing:
Reverse Osmosis water should not be run through
copper tubing as the purity of the water will leach copper causing
an objectional taste in water and pin holes may form in the tubing.
Watts supplies speciality filters that can be used if copper tubing
follows the Reverse Osmosis unit . Be sure to follow any state or local
regulations during installation .
Drill a Hole for the Faucet in a Porcelain Sink
Note: Most sinks are predrilled with 1½" or 1¼" diameter hole
that you can use for your RO faucet. (If you are already using it
for a sprayer or soap dispenser, see Step 2).
Caution: Porcelain sinks are extremely hard and can crack or
chip easily.
Use extreme caution when drilling. Watts accepts no responsi-
bility for damage resulting from the installation of faucet.
Step A –
Determine desired location
for the RO faucet on your sink
and place a piece of masking
tape on over where the hole is
to be drilled . Mark the center
of the hole on the tape .
Step B –
Using a variable speed drill
set on the slowest speed, drill
a
1
⁄
8
" pilot hole through both
porcelain and metal casing
of sink at the marked center
of the desired location . Use
lubricating oil or liquid soap
to keep the drill bit cool (If drill
bit gets hot, it may cause the
porcelain to crack or chip) .
Step C –
Using a 1¼" hole saw, pro-
ceed to drill the large hole .
Keep drill speed on the slow-
est speed and use lubricating
oil or liquid soap to keep the
hole saw cool during cutting .
Step D –
Make sure the surroundings
of the sink are cooled before
mounting the faucet to the
sink after drilling and remove
all sharp edges .
STEP 1
Punch a Hole for the Faucet in a Stainless
Steel Sink
Note: If mounting faucet to a Stainless
Steel Sink, you will need a 1¼" Hole
Punch. The faucet opening should be
centered between the backsplash and
the edge of the sink, ideally on the
same side as the vertical drain pipe.
Step A –
Drill a ¼" pilot hole. Use a
1
⁄
2
"
Hole Punch and an adjustable
wrench to punch the hole in the
sink. Change to the 1¼" Hole
Punch to enlarge the hole
The faucet can now be installed .
