SECTION 1
Equipment Description
The FORMULA Reverse Osmosis Drinking Water treatment system consists of three
components: the Reverse Osmosis filter assembly, the Storage Tank, and the Service
Connections.
REVERSE OSMOSIS FILTER ASSEMBLY
MODEL IDENTIFICATION: The filter assembly consists of two 10-inch pre-filters in series, the
reverse osmosis membrane, the post-filter, and the auto-shutoff valve. Model II is a standard 15
gpd, Model III is a standard 25 gpd, and Model III+ is a modified 35 gpd.
PRE-FILTER: Table 1 shows the various configurations of suspended particle filters and
dechlorinating filters used in the FORMULA product line. The particle filters are used to prevent
damage to the Reverse Osmosis membrane and to prevent clogging of the flow control and
auto-shutoff valve. The dechlorinating filter is a carbon block filter, no fines carbon cartridge
containing approximately 4 million square feet of surface area. This carbon is capable of treating
approximately 6,000 gallons of water entering the filter with a free chlorine residual of 2.5 ppm.
The carbon filter is required to protect thin film membranes from free chlorine. Change the
carbon filter every year or sooner depending on your water supply and dealer
recommendations.
R.O. ELEMENT HOUSING: The housing contains the reverse osmosis membrane, which is
the backbone of the system. The R.O. membrane element separates the clean water at the
molecular level from the majority of impurities and stores the “product”, or R.O., water in the
storage tank. The above impurities are concentrated in the waste or “brine” water and sent to
drain. The R.O. housing element is the large, white vessel mounted with twowhite “C” clamps.
POST FILTER: The post filter contains activated carbon and is used solely for marketing
reasons after the water leaves the storage tank. The post filter is white and mounted in front of
the R.O. element housing.
AUTO SHUTOFF VALVE: Prevents water flow to drain when product tank is full.

STORAGE TANK: The storage tank assembly is used to store approximately 3 gallons of R.O.
water. The tank is pressurized with an air charge of 5 to7 psi to force water back to the faucet.
Note: If system is installed in unusually cold environment or the system is treating very cold
water, the air charge of the tank may need to be increased. This is due to contraction of the air
inside the tank when exposed to a low temperature environment. Conversely, if the system is
installed in high altitudes or very high temperatures, some air may need to be bled from the
permanent tank charge to achieve a 5-7 psi tank pressure. It is possible to operate the tank in a
horizontal position. The tank will discharge completely in any position. Although the tank has
3.2-gallon maximum capacity, the actual quantity of water that can be stored will be a function of
the incoming raw water pressure, T.D.S. and temperature. A 1/4” valve is provided to isolate the
storage tank from the system.
SERVICE CONNECTIONS: The sink-top faucet is dedicated to dispense water from the
storage tank. It can rotate a full 360 degrees and can dispense water continuously or
intermittently. The faucet is equipped with an “air gap” feature to prevent a cross connection
between the potable water supply & waste water drain.
The T-Link Ball Valve is used to provide raw water feed to the R.O. systems and is designed to
attach to most under sink plumbing. Note that the R.O. must be fed COLD water only. Hot water
will permanently damage the system and void the warranty. The T-valve will also serve as a
shut-off to the system.
The drain saddle 1/4” is used for the R.O. waste water and can be easily installed on either PVC
or metal pipe drains.
A Tee with plug is available for Icemaker connection and is found on the outlet side of the
post filter. Note the gray plastic plug located in this fitting. It is to be left in place if no auxiliary
connections are to be made. To remove the plug, cut the head off the plug, unscrew the fitting
and push the plug through the grab ring (see section 6 for reference).

General Instructions
CAUTION: CONNECTING THE SYSTEM TO HOT WATER (OVER 1OOoF) WILL DESTROY.
THE MODULE AND VOID THE WARRANTY.
1. PREPARATION
A. The filter assembly should be mounted on or against a vertical surface in a position to allow
access for service and filter cartridge replacement. At the same time: the assembly should be
relatively near the faucet to maximize flow.
B. The storage tank should be located where it can be removed if necessary, but does not take
away needed storage space. The storage tank may be placed on its side.
C. The sink top faucet should be positioned to assure a free-flow into the sink. It must also be in
a location that allows ready access to the mounting hardware from under the sink.
2. INSTALLATION OF T-VALVE ASSEMBLY
A. Turn off the Cold Water Supply
B. The i-Link Ball valve Assembly may be used to make connection to3/8” plastic, copper or
corrugated tubing. To install, carefully cut the tubing with hacksaw or tubing cutter. Usually a
single cut is all that is needed. Remove nuts and rubber grommets from the T-Link. Place
one of the nuts and one of the rubber grommets on each piece of tubing and screw the nuts
onto the T-Link. A slight bend in the tubing might be needed to accommodate the T-Link.
C. Firmly push one end of the 1/4” yellow raw water feed tubing into the valve.
3. INSTALLATION OF FAUCET ASSEMBLY
Note: The system is equipped with an “air gap” faucet to prevent a cross connection between
the raw potable water supply and waste water drain.
See page 6 for faucet installation and assembly instructions.

4. INSTALLATION OF THE RO DRAIN
CAUTION: The R.O. Drain should be installed above the trap and on the vertical or horizontal
tailpiece. It should never be placed on the same side of the drain system as the garbage
disposal or subsequent overflowing of the R.O. Drain Air Gap will occur. To minimize the
dripping sound of the reject water entering the drain, the R.O. Drain Saddle can be located
either high on the vertical drain tube or on a horizontal drain tube.
A. Drill a 3/8” hole into the drainpipe, observing the above “Caution” concerning positioning.
B. Attach the drain saddle lining up the drain holewith the hole drilled in the plumbing.
C. Hand tighten both screws evenly using aPhilips screw driver
5. MOUNTING THE FILTER ASSEMBLY
The Filter Assembly can either be mounted on the cabinet sidewall so that the filters are up off
the cabinet floor or the assembly can be set on the cabinet floor. Care must be taken to
assure the sidewall is sufficiently strong to support the 15-pound weight of the operating
assembly
A. Hold the Filter Assembly on the side wall at adequate clearance for removal of pre-filter
bowls. Remove the Filter assembly and mark the mounting screw centers. The mounting
screws must be 6” center to center, with at least 2” vertical clearance above them.
B. Drill 1/8” holes at the center marks.
C. Screw the #10 X 3/4 hex screw into the sidewall leaving enough protruding to allow the
bracket mounting slots to slide over them.
D. Mount the Filter Assembly on the hex screws.
6. STORAGE TANK
A. Place Storage Tank in the desired location.

Faucet Installation
NOTE: THIS FAUCET IS DESIGNED FOR USE WITH RESIDENTIAL REVERSE OSMOSIS
SYSTEM AND MEETS ALL APPLICABLE PLUMBING CODES AND STANDARDS. BACK
FLOW PREVENTION IS PRODED WHETHER CAUSED BY BACKPRESSURE OR BACK
SIPHONAGE.
General instructions:
Note: The system is equipped with an “air gap” faucet to prevent a cross
connection between the raw potable water supply and waste water drain.
A. Drilling porcelain enamel sinks.
This is not complicated but requires caution and patience. Porcelain is a glass-like material that
covers a base metal, so extreme care should be taken to keep from chipping this surface. There
are several methods that allow ceramic sinks to be drilled safely and easily. One that we
suggest is:
1. Locate faucet placement and tape off the area with masking tape.
2. Using a drill at slow speeds, drill through the porcelain using 1/4” carbide tipped drill.
Note: The bits dull in a very short period of time when used for drilling porcelain and should
be replaced or sharpened frequently.
3. Cut through the porcelain and base materials using a 1 -1/4” carbide tipped hole saw at
very slow speeds.
A second method to cut through a porcelain enamel sink is to use a Relton® Porcelain
Cutter Kit, which is available through a full line plumbing Supply Company. Remove
metal chips immediately from the sink surface as stains will occur.

B. Drilling aCeramic Tile Counter
1. Take off the ceramic layer of the tile using a silicon carbide grinding wheel. Grind away
enough of the material to accommodatea 1-1/4” carbide drill bit.
2. Operate the drill at low speeds, especially when the bit is about to penetratethe tile.
C. Drilling Stainless Steel Sinks
1. Determine faucet locations and center punch the stainless for the drill bit.
2. After drilling a pilot hole using a high speed carbide bit, increase the bit size until you
have drilled a hole at least 1-1/4” in diameter.
Step-by-step assembly:
STEP 1
Read all instructions before beginning installation. Verify that all parts have been received.
STEP 2
Prepare mounting hole:
