Rainfresh RO450 Instruction Manual

Reverse Osmosis (RO) Drinking Water System
Model RO450/RO450M
Installation & Maintenance Manual (Please save for future reference)
INTRODUCTION
The Rainfresh RO system uses hyper-filtration technology (commonly called Reverse Osmosis or RO). The four-stage filtration
system reduces molecular and ionic contaminants by up to 99% - Barium, Cadmium, Chromium, Copper, Fluoride, Lead, Mercury,
Nitrates, Sodium, Total Dissolved Solids, Chlorine,Taste and Odour. It also traps protozoan cysts (Cryptosporidium & Giardia) greater
than 99.95% and filters sediment, silt and rust. Water produced by the Rainfresh RO system can be used for drinking, cooking, juices,
beverages, watering plants, steam irons, humidifiers, aquariums etc.
OPERATING SPECIFICATIONS
(1) Do not use with water that is microbiologically unsafe or of unknown quality, without adequate disinfection before or after the system. Systems certified
for cyst reduction may be used on disinfected water that may contain filterable cysts. For effective disinfection we recommend Rainfresh Whole-house
UV disinfection systems.
Warning: Individuals requiring water of specific microbiological purity should follow the advice of their doctor or local health unit.
(2) If water pressure can exceed 100psi, a pressure regulator and water hammer arrestor must be installed before the filter. Recommended regulator
setting is 60-75 psi.
(3) System will operate with hard water, but membrane life may be shortened.
The unit should be operated with water that meets the following minimum criteria. Source water exceeding chemical parameters (listed
below) requires pre-treatment.
Raw Water Supply Chemical Parameters
Water Supply = Bacteriologically Safe (1) Max Hardness < 170mg/L (<10 gpg) (3)
Feed Water Pressure = 40 (min) to 100 psi (max) (2) Iron (Fe) < 0.1 ppm (mg/L)
2.8 Kg/cm2 to 7.4 Kg/cm2 Manganese (Mn) < 0.05 ppm (mg/L)
Feed Water Temp. = 4ºC - 38ºC (40ºF - 100ºF) Hydrogen Sulfide = 0.00 ppm (mg/L)
Feed water pH = 3.0 to 11.0 Feed Water TDS (max) = 1500 ppm (1500 mg/L)
Feed Water Turbidity = 1.0 NTU (max)(NTU - Nephelometric Turbidity Unit
Production Rate = 18.1 US gpd (68.5 Lpd)
Average efficiency rating - 9.7% - Efficiency rating means the percentage of the influent water to the system that is available to the user as RO treated water
under operating conditions that approximate typical daily usage.
Average recovery rating - 18% - Recovery rating means the percentage of the influent water to the membrane portion of the
system that is available to the user as RO treated when the system is operated without a storage tank or when the storage tank is bypassed.
This system is acceptable for treatment of influent concentrations of no more than 27 mg/L nitrate measured as N and is certified for nitrate reduction only for
water supplies with a pressure of 40 psig (280 kPa) or greater.
For optimum performance of the system, filters should be replaced as per following:
Pre-filter 1& 2 - Model CF2: Replace every six months
Post-filter - Model IM200: Replace every six months
RO Membrane - Model ROM50: Replace every 2-4 years
Note : Cartridge and membrane life is directly dependent on your water conditions and the volume of water filtered. Excessive
sediment and other contaminants may require more frequent replacement.
Note: This reverse osmosis system contains a replaceable membrane critical to the effective reduction of total dissolved
solids . Raw and product water should be tested every six months by a water analysis lab to verify that the system is perform-
ing properly. Only replacement membrane model RO50M should be used to assure the same efficiency and contaminant
reduction performance.
Nitrate Reduction Performance
A Nitrate test kit is included witht this system to verify Nitrate-reduction performance. The test should be performed at installation
(after 3 tank flushes) and at least every six months thereafter.
Instructions: The test kit included has two test strips. You need only one test strip per test. Follow instructions on the test package.
Compare the colour to the test strip with the nitrate nitrogen colour shades on the test package. The colour should match with10 ppm
or less.
Additional testing and verification for reduction of Barium, Cadmium, Chromium, Copper, Fluoride, Lead and Chlorine performed by
independant laboratory. Claims not performance certified by WQA gold seal program.
Tested and Certified to NSF/ANSI standard 58 for the reduction of TDS, Nitrate, Mercury, Sodium, Cyst
(e.g. Cryptosporidium & Giardia).
System tested and certified by the Water Quality Association against CSA B483.1

INSTALLATION CAUTIONS
1 The RO system is designed for point-of-use (POU) under-sink installation for single-faucet dispensing only.
2. Installation of this unit may involve some water spillage. Keep an ample supply of paper towels or an absorbent cloth
handy.
3. This system is intended for use with cold water only. Hot water can damage the membrane.
4. Do not attempt to operate the system without the pre-filters. This can severely damage the membrane.
5. Ensure that there are no kinks in any of the tubing that can restrict or stop the water flow and cause damage to
the system.
6. Protect filter from direct sunlight. Not intended for outdoor use.
7. Protect your unit from freezing temperature.
2.
HOW YOUR RO SYSTEM WORKS
Water first flows through two stages of pre-filtration consisting of block activated carbon filters. The third and most important stage of
the system is the Reverse Osmosis Membrane that rejects most of the dissolved contaminants listed above, while the filtered water
(called Permeate) passes through a final stage of taste and odour polishing, before flowing out of the faucet. As the RO membrane
rejects contaminants at a molecular level, some of the water, along with the contaminants, flows to the drain. To achieve such fine
filtration, the water production rate is slower than conventional under-sink filtration systems. Therefore, a pressurized storage tank is
used to provide RO water through the faucet at normal flow and pressure. The storage tank holds a maximum of 2.2 US gallons
(approx. 12 liters) of filtered water. When the storage tank is full, an automatic valve shuts off the water supply to the RO membrane.
As water is used from the faucet and the pressure in the tank drops to about 65% of full pressure, the automatic shut-off valve opens
and allows feed water into the RO membrane until the storage tank is full again. Model RO450M also features an electronic monitor
that tracks the 6-month filter life and blinks when it is time for the pre & post filters to be changed.

INSTALLATION
Necessary Installation Tools
Variable speed drill, drill/spade bits - 3/8", 7/8", utility knife, 2 adjustable
wrenches, flashlight, flat-head & phillips screwdrivers.
Fittings and Tubing (See Fig. 2)
Accu-Link™ quick-connect fittings are used throughout the system with the
exception of the self-piercing saddle valve and faucet connections. To ensure an
optimal seal, tubing should be cut straight. An angled cut or distortion of the
tubing will not provide an efficient seal and may cause leaks. To install a 1/4”
tube (blue, white, grey, red), mark it 5/8” from the end then push it firmly 5/8”
through the collet, past the o-ring until it seats on the tube stop. Note: For 3/8”
black tube, mark and push tube in 3/4”.
To remove a tube, push in the collet with two fingers on each side of the tube
and pull out the tube. All extra tubing (grey, red, black, blue only) should be cut
so that only optimum length of tubing remains. Loops or extra lengths of tubing
are not recommended. Cut tubing to size wherever necessary.
Starting Your Installation
System and installation shall comply with state and local regulations.
This unit comes complete with filter, cartridges, membrane, air-gap faucet,
housing assembly, pressurized storage tank, do-it-yourself instructions and all
necessary fittings to install the unit below the counter to copper or CPVC pipe.
A typical installation is shown in Fig. 1 on page 2. Installation of the unit includes the following
steps:
1. Air-gap faucet connection 4. Feed water connection.
2. Drain connection 5. Storage tank connection
3. Mounting the main unit.
Air-gap Faucet Installation (See Fig. 3)
The faucet (2640-0) may be installed on the counter-top or the sink, as desired. For counter-top
installation, position faucet on counter-top beside sink where it will not be obstructed from above
or below.
For Porcelain/Enamel Sinks
A spring-loaded Relton style drill set is strongly recommended to prevent chipping.
Use a carbide-tipped drill bit to drill a 1/8” pilot hole completely through the porcelain. Use
lubricating oil or liquid soap to keep the drill bit cool while drilling. Next, using a
spring-loaded porcelain saw, cut through the porcelain surface only. Finally, use a 7/8” fin-
ishing hole saw to cut through any remaining metal. Avoid high motor RPM during the ini-
tial cutting of the porcelain as this can cause chipping.
For Stainless Steel Sinks
Make a small indent to mark the desired drilling location using a centre punch. Drill a pilot
hole with a 1/8" metal drill bit. Enlarge the hole using a 7/8" metal drill bit. Then
de-burr the hole and file smooth.
For Laminate Countertops
1. Mark the location and drill a 7/8” hole.
2. Insert the faucet tubing (1/4” grey and 3/8” black) first through the countertop hole
followed by the faucet with drain hole in faucet body facing sink.
3. Install slotted washer (2640-4), spacer (2640-5), bottom washer (2640-6) and lock-nut
(2640-7). Tighten lock-nut while someone holds the faucet so it does not turn.
4. Slide compression nut (1030-15), sleeve (1008-3) on to one end of blue tube (2622)
and push insert (1603) into end of tube as shown in Fig 6. Push tube into threaded
end of faucet and hold firmly in place and tighten nut securely with a wrench,
again while someone holds faucet so it does not turn.

Drain Connection
1. Mark a spot on the vertical drain pipe under sink and drill a 3/8"
(9 mm) hole in it, preferably facing direction of faucet. Make sure that while drilling you do not drill right through the other side
of the pipe.
2. Peel the protective film off the sponge gasket and apply to inside of
drain saddle (2618), using care to align sponge gasket hole with
drain saddle hole.
3. Mount the drain saddle on the drain pipe and align the drain saddle
hole with the 3/8” drilled hole (use a flashlight to see clearly). Use a drill
bit or any narrow straight object to confirm that the two holes are aligned.
Tighten the saddle nuts and firmly secure the saddle in place. Do not
over-tighten. (see Fig. 4)
4. Measure length of 3/8” black drain tube (2624) needed to connect
to drain saddle. CAUTION: This is a gravity drain line and should be as
short as possible (See Fig. 1). Water may leak from drain hole on the
faucet. Cut off any excess tube and connect to drain saddle. Mark tube
3/4” from end and insert firmly 3/4” through collet past O-ring until it
seats on tube stop (See Fig. 2).
Mounting the main unit
Locate best side wall position for mounting unit under-sink near faucet.
NOTE: Leave a minimum of 5 inches clearance below sumps to allow for removal of cartridges. The higher and closer
to the front you mount the unit, the better it will be for regular maintenance/servicing.
1. Unpack unit and pull post-filter (IM200) towards front to expose mounting bracket (2613). Mark mounting bracket screw
locations using mounting bracket as a template and set unit aside.
2. Partially screw the two mounting screws (1011-0) into screw locations.
NOTE: If wall is too thin to accept screws, use round-head nuts and bolts (not supplied) to mount bracket. Install
pre-filters and membrane as per instructions below before mounting unit on the wall.
3 Installing Pre-filters:
a) Turn each sump (520) 1/8 turn to left and pull away from head (2501) to remove.
b) Pull pre-filters (CF2) gently away from head, remove shrink-wrap and re-install open end of pre-filters on to head
boss.
c) To replace sumps, align sump grooves with head lugs and push straight up on to the head. Turn sumps 1/8 turn to right
fully to stop (lock position).
4. Installing the RO Membrane (See Fig. 5)
To make membrane installation easier, the tube to the
membrane housing cap (2601) is not connected when the unit is
shipped.
a) Unscrew the membrane housing cap and take it off .
b) Remove new membrane (ROM50) from bag and apply silicone
lubricant (included) on the two "O" rings. Caution: Do not
use any other lubricants.
c) Slide membrane into housing, O-ring side first. Push
membrane completely in until slotted end is flush with housing
opening. If you cannot push membrane fully in, pull it out
and apply some more lubricant and repeat procedure.
d) Replace housing cap taking care that the "O" ring inside it
does not come out. Firmly hand-tighten the cap.
e) Insert unconnected white tubing into housing inlet fitting
(2609). Mark tube 5/8” from end and push firmly 5/8” through
collet past O-ring until it seats on the tube stop (See Fig. 2).
5. Installing the monitor battery (Model RO450M only)
a) Remove plastic cover (2508) on top of the inlet pre-filter housing by prying up gently with finger nails at front and back.
b) Unwrap battery (2545) and insert “+” side up into battery slot and replace cover. Press and hold black button until
orange LED blinks four times; then release button to set monitor.
6. Mount the unit on to the mounting screws and tighten screws.
7. Connect grey drain tube (2623) from faucet to drain fitting (2609) (See Fig. 1 inset). Flow restrictor (2611-1) is installed at
the end of the grey tube. Insert this end of the grey tube (with 2611-1) into the drain fitting (2609) as shown in fig 1 inset.
8. Measure length of 1/4” blue tube (2622) from faucet needed to connect to open left end of post-filter (IM200) without kinks
and cut off any excess (See Fig. 1). Mark and insert tube 5/8” as shown in Fig. 2.

Saddle Valve Installation
NOTE: The Saddle Valve (1008-1) can be installed on copper or CPVC rigid plastic pipe of 3/8" to 1" diameter.
(Not recommended for flexible plastic pipe).
NOTE: If your cold water line is other than described, use fittings (not included), that adapt to 1/4” OD tubing or contact
Envirogard for assistance.
IMPORTANT: Orient saddle valve with outlet threads pointing towards INLET fitting (2606) (see fig 1).
1. Back-off handle on saddle valve to retract piercing tip. With rubber
gasket in a fixed position clamp entire assembly to pipe using bolts
provided. Tighten bolts, keeping brackets parallel until rubber gasket is
firmly compressed.
Caution: Do not over-tighten.
2. Measure length of 1/4” red plastic tubing (2619) from RO inlet
needed to connect to saddle valve without kinks and cut off any
excess tube.
3. Slide compression nut (1030-15) and sleeve (1008-3) onto tube,
then put tube insert (1603) into tube (see Fig. 6). Push tube into end
of saddle clamp fitting and hold firmly in place. Securely tighten
compression nut while holding other end of fitting with a wrench.
Storage Tank Connections
Caution: DO NOT TAMPER WITH THE AIR VALVE ON THE STORAGE TANK. IT
HAS BEEN FACTORY PRE-SET AT 5-6 PSI (EMPTY PRESSURE)
1. Place the storage tank on its base under the sink. The tank valve
(2617) and white tubing (2620) are pre-connected to the tank.
2. Insert open end of 1/4” white tube (2620) into “Tee” fitting (2612) at right end
of post-filter (IM200). Mark and insert tube 5/8” (See Fig. 2).
START - UP PROCEDURE
1. Turn the feed water saddle valve clockwise until handle is seated. You have now
pierced the pipe and closed the valve.
2. Open your under-sink cold water valve, or the main water shut-off valve, whichever you had closed and check for leaks.
Turn saddle valve handle counter-clockwise all the way to open valve and start water flow. Check all fittings for leaks.
3. Turn storage tank valve one quarter turn left (counter-clockwise) to open. The handle should be in line with the tubing as it
enters the connection (See Fig. 7).
4. Your unit is now in operation.
NOTE: Do not consume the water prior to three tank flushes. See tank flushing procedure below.
NOTE: A mild dripping or gurgling sound should be heard from the drain-hole in the faucet when the RO system is making water.
This is normal.
Flushing the Tank
Allow the storage tank to fill up. This can take from 2-5 hours depending on your feed water pressure. Open the faucet and
flush out the tank completely until it is fully drained. Repeat procedure for two more tank flushes. This
procedure is required to flush out the sanitizing solution in the RO membrane.
The system is now ready for use.
OPERATION AND MAINTENANCE
Electronic Monitor Functions (Model RO450M only)
The electronic monitor tracks the 6 month period and the orange LED blinks when the limit is
reached, advising you to replace the two pre-filters (Model CF2) and the post-filter (Model IM200) as
soon as possible. The monitor does not track the life of the RO membrane. Set monitor before
beginning service and re-set after cartridge replacement as follows:
Setting/Re-setting the monitor (See Fig. 8)
Press and hold black button until orange LED blinks 4 times, then release button. This activates
monitor function that tracks time used. When 6 months expire, the orange light will blink every 5
seconds advising you to replace the cartridges.
Battery Life - Approximately 4 years. To test battery - Press black button for two seconds or less. If Orange LED lights, then
power is on and monitor is working. Replace battery when LED does not light. To replace battery, remove plastic cover by prying
up gently with finger nails at front and back. Pull used battery out of slot and push new battery (2545) into slot “+” side up
and replace cover.

MAINTENANCE / PRECAUTIONS
Caution: If your unit is not used in winter, or will be subject to freezing temperatures, drain unit and remove cartridges from sumps.
Place cartridges in sink or on a paper towel to dry, which will occur in several days. Remove membrane and place it in a sealed
plastic bag with a few drops of RO water and store in your refrigerator. For re-start, follow annual sanitization
procedure.
Note: Lubricate Head O-rings (2502) at least once a year or when draining for winter. Use food grade silicone grease (i.e. Dow 111
Compound) or any other non petroleum lubricant. Water conditions can be hard on rubber seals. Head O-ring replacement at least
every two years is recommended to minimize wear and tear and prevent leakage.
Caution: Due to a limited product service life and to prevent costly repairs or possible water damage, we strongly recommend that
sumps (#520) be replaced every 5 years. If sumps of your RO system have been used for more than this period, replace immedi-
ately. Date the bottom of any new sump to indicate next replacement date.
Do not clean the system with organic solvents such as those found in sprays for cleaning products or insecticides as these may
cause cracking or crazing and lead to failure and leakage.
