4. Reverse Osmosis Feed Water
Connection – The Reverse Osmosis Feed
Water Ball Valve should be located as
close to the manifold assembly as
possible. USE A POTABLE COLD WATER
SUPPLY ONLY TO YOUR REVERSE
OSMOSIS SYSTEM. Softened water is
preferred as it will extend the life of the
Reverse Osmosis Membrane.
5. Reverse Osmosis Drain Connection –
The Reverse Osmosis waste water must
go to a drain connection with easy access.
Do NOT connect the Reverse Osmosis
system drain line to the dishwasher drain
or near the garbage disposal.
2b. Drilling a porcelain sink:
It is best to use a special 1¼" diameter cutter
designed for porcelain. A carbide tipped
masonry bit is a second choice.
•
Place a piece of tape over the area to be
drilled to help prevent chipping.
•
Drill a pilot hole for the porcelain cutter. Use
the pilot drill supplied with the kit or a carbide
tipped drill.
•
When drilling the 1¼" hole, drill slowly and
carefully; the porcelain chips easily.
•
After drilling, clean the area well. Iron fillings,
if left in place, can cause rust stains.
REVERSE OSMOSIS INSTALLATION
STEPS
All plumbing should be done in accordance
with local plumbing codes.
In restricted under-sink areas, it may be easier
to install the Reverse Osmosis faucet first.
Allow adequate Reverse Osmosis tubing
lengths for any final Reverse Osmosis
component position.
A. Reverse Osmosis Faucet Installation
2a. Drilling a stainless steel sink:
•
Center punch the hole to provide a
starting point for the drill.
•
Start with a smaller drill as a pilot, and
then drill a ½" diameter hole to accept
the bolt of a 1¼ " Greenlee Hole Punch
(1¼" chassis punch).
•
Clean away any chips.
•
Install the punch and tighten the nut to
cut the hole.
•
Deburr any sharp edges.
2c. Drilling a counter top:
NOTE: The counter top must be less than 1¼"
thick. Treat ceramic tiles as porcelain until the
tile is penetrated, then use the carbide tipped
metal cutter.
Formica counter tops may be drilled with a good
1 ¼" wood bit, drilling a 3/32" pilot hole will help
keep the bit going straight.
IMPORTANT NOTICES:
This Reverse Osmosis system contains replaceable treatment components critical for effective performance. It is the user's responsibility to,
and the manufacturer strongly recommends that the user periodically test the Reverse Osmosis product water to verify the Reverse
Osmosis system is performing satisfactorily.
The Reverse Osmosis system is acceptable for water treatment of influent concentrations of no more that 27 mg/l nitrate and 3 mg/l nitrate
in combination measured as N and is certified for nitrate/nitrite reduction only for water supplies with a pressure of 40 psig (280 kPa) or
greater.
DO NOT USE WITH WATER THAT IS MICROBIOLOGICALLY UNSAFE OR OF UNKNOWN QUALITY, WITHOUT ADEQUATE
DISINFECTION BEFORE OR AFTER THE SYSTEM.
Reverse Osmosis Systems certified for cyst reduction may be used on disinfected
water that may contain filterable cysts.
