PRECAUTIONS
GENERAL
Do not use with water that is microbiologically
WARNING:
unsafe or of unknown quality without adequate
disinfection before or after the system.
Systems certified for cyst reduction* may be
used on disinfected waters that may contain
filterable cysts.
*NSF/ANSI Standard 53 and 58 certified to reduce cysts such
as Cryptosporidium and Giardia by mechanical means.
RO System must be protected against freezing,
CAUTION
which can cause cracking of the RO components
and water leakage.
NOTE:
• Your water must be within required limits for satisfactory
operation. If not, your membrane life may be shortened and
your warranty will be voided (see Specifications on page 3).
• This reverse osmosis system will not protect against
disease-causing bacteria or remove naturally-occurring
harmless bacteria.
• Install on cold water line only.
• Make certain that installation complies with all state and
local laws and regulations.
• The replacement cartridges and reverse osmosis element
included with this system have limited service lives. Changes
in taste, odor, and color of the water being filtered indicate
that the cartridge should be replaced.
• After prolonged periods of non-use (such as during a
vacation) it is recommended that the system be flushed for 5
minutes before it is used.
• A drinking water cartridge may contain carbon fines (very
fine black powder). After installation, flush the system for 5
minutes to remove the carbon fines before using the water.
• It is recommended that you run the tap at least 20 seconds
prior to using water for drinking or cooking purposes.
• The contaminants or other substances removed or reduced
by this water treatment device are not necessarily present in
your water.

HOW REVERSE OSMOSIS WORKS
The GRO-475BP Reverse Osmosis (RO) System uses a
semi-permeable membrane to reduce dissolved salts and
minerals, improving the taste and odor of your water. The RO
membrane is made of layers of micron-thin film wound around
a hollow center core. Water molecules can pass through the
membrane, but dissolved salts and minerals are rejected.
The GRO-475BP Reverse Osmosis System features 4-stage
filter action. Your water supply is pre-filtered to reduce dirt
and chlorine that may foul the membrane. The RO membrane
separates this pre-filtered water into PRODUCT WATER and
DRAIN or REJECT WATER. Incoming water pressure forces
the product water through the membrane and into the storage
tank. Dissolved solids and other contaminants cannot pass
through the membrane and are sent to the drain as reject
water. When you open the drinking water faucet, product water
is drawn from the storage tank through an activated carbon
post-filter, providing you with cleaner, great-tasting water.
For each gallon of water produced, several gallons are
discharged as reject water. The storage tank can hold up to
2.1 gallons (7.9 L) of water at a time, for drinking and cooking
needs. When used under the Specifications on page 3 of the
manual, your Reverse Osmosis membranes should last 12-24
months.
INSTALLATION
GROUNDING INSTRUCTIONS: This appliance must be
grounded. In the event of a malfunction or breakdown,
grounding will reduce the risk of electric shock by providing a
path of least resistance for electric current. This appliance is
equipped with a cord having an appliance-grounding conductor
and a grounding plug. The plug must be plugged into an
appropriate outlet that is installed and grounded in accordance
with all local codes and ordinances.
Improper connection of the appliance-
WARNING:
grounding conductor can result in a risk
of electric shock. Check with a qualified
electrician or service representative if
you are in doubt whether the appliance is
properly grounded. Do not modify the plug
provided with the appliance; if it will not fit
the outlet, have a proper outlet installed by a
qualified technician.
A. The power-supply receptacle for the
appliance shall be installed in a cabinet or on
a wall adjacent to the undercounter space in
which the appliance is to be installed;
B. There shall be an opening through
the partition between the compartments
specified in (a) that is large enough for
the attachment plug to pass through. The
longest dimension of the opening shall not
be more than 1-1/2 in (38 mm);
C. The edges of the opening specified in (B)
shall, if the partition is wood, be smooth
and rounded, or, if the partition is metal, be
covered with an edge protector provided for
this purpose by the manufacturer; and
D. Care shall be exercised, when the
appliance is installed or removed, to reduce
the likelihood of damage to the supply cord.
