(A) INTRODUCTION
Your Rainfresh TWIST Drinking Water System uses a premium dual-stage
filtering process, providing cleaner, safer, better tasting drinking water for
your family. It reduces chloramines, lead, VOC (volatile organic compounds),
cysts, chlorine, bad tastes and odours (see performance data sheet for
details)*. The system is designed for installation under the kitchen sink and
includes a ceramic-disc faucet for dispensing filtered water.
*Contaminants reduced by this system are not necessarily in your water.
The “Twist ON/Twist OFF” design makes cartridge replacement quick and
easy, using no tools and without having to shut off the water.
The system features a unique electronic monitor (QS2 only) that tracks both
the gallons used and time in service and triggers a blinking orange LED when either of these limits is
reached advising you to replace the cartridge.
(B) SAFETY INSTRUCTIONS
oThis filter system is designed for residential point-of use undersink indoor installation only.
oProtect filter from direct sunlight.
oIf water pressure will at any time exceed the 100 psi maximum, a pressure regulator and water hammer
arrestor must be installed before the filter to prevent potentially damaging shocks caused by high
pressure. Recommended regulator setting is 75 psi / 5.1 bar/ 517 kPa or less. Not intended for
installation in multi-storey buildings over 4 storeys.
oDo not subject to freezing temperatures with water inside the unit. If your unit will not be used in winter,
or will be subject to freezing temperatures, drain unit completely (see “Maintenance” section for details).
oThis system is intended for use with cold water only. DO NOT INSTALL ON HOT WATER.
oOnly use Rainfresh TWIST filter cartridges with this unit. No other filter cartridge will fit or
function with this system.
oDo not lubricate O-rings with petroleum based lubricants. Only food-grade silicone (Dow 111
compound) should be sparingly used.
oDo not clean unit 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.
oInstallation of this unit may involve some water spillage. Keep an ample supply of paper towels or an
absorbent cloth handy.

(D) INSTALLATION
Installation shall comply with applicable state and local regulations
TOOLS REQUIRED: Drill, ½” drill bit, Philips & flat-head screwdrivers, adjustable wrench, marker or pencil, a
sharp knife and measuring tape.
Unpacking the unit
The following items are included in the box:
Remove both cartridges (QCA & QLV) by turning it 1/4 turn left, then pulling away from head assembly (see
Fig 9). Place it aside in a safe place until final assembly.
The following instructions are for installing the TWIST system under the sink. It can also be installed on any
other wall mounted remote location (such as basement or crawl space) from where tubing can be run to the
faucet. The unit should not be installed more than fifteen feet away from the faucet. Call Rainfresh if you have
questions.
Step 1: Mounting the Faucet
Faucet may be installed in hole in sink if
available or in counter top. Note: The
faucet may also be installed in the sink
sprayer hole if available.
1. Position faucet on counter top
beside sink in desired position.
Ensure that swivel spout will
extend over sink and that there is
room under the counter for faucet
shank and to tighten nuts.
2. Mark the location and drill a ½”
hole (fig 2). Protect your counter
top by applying a layer of masking tape and use a sharp drill.
3. Insert faucet shank through escutcheon washer (1050-10), and
then through counter top (See Fig. 3). Install plastic locating
washer (1050-12), lock washer (1050-13) and locking nut (1050-
14). Tighten locking nut securely while someone holds the faucet body so it does not turn.

Step 2: Install battery (For model QS2 only)
Before mounting the unit, install the monitor battery.
Remove head cover insert (2718) by gently pulling away
the insert from the head. Unwrap coin battery (2545) and
insert into battery slot between contacts with + side out.
Do not reattach the head cover insert yet.
Step 3: Mounting the Unit
Locate best position for mounting unit undersink near faucet. The higher and closer to the front you mount the
unit the easier it will be for regular maintenance (see Fig 1). There are 3 mounting bracket screw locations –2
located on the bottom of the head cover and 1 is located at the center between the two filter heads.. Note:
Screw holes at bottom should be at least 12 inches up from the base of the cabinet (you must allow at
least 3 inches of clearance below the cartridges for easy removal).
Screw in the 3 screws making sure that the head assembly is level. Note: If wall is too thin to accept screw then
use round head nuts and bolts (not supplied) to mount head assembly. For model QS2, Now re-attach the head
cover insert (2718), carefully aligning it so that the black button on the monitor lines up through the hole on the
cover insert.
Step 4: Connecting the faucet
Measure the tubing required to connect faucet to the white OUTLET
Acculink™ fitting (arrow pointing away from the fitting) and cut this
length from the tubing supplied. Make a straight cut as shown in Fig 4.
NOTE: Use only a sharp knife to cut the tube straight.
Warning: Angled or rough cuts can cause a water leak.
Slide compression nut (726-0) and compression sleeve (1008-3) onto
tube and put tube insert (1603) into tube as shown in Fig. 5. Now tighten
nut securely with a wrench.
Identify the INLET & OUTLET of the unit (Fig 6A). Connect the other end
of tubing to OUTLET AcculinkTM fitting by pushing the tube into the
fitting until it touches the tube stop and cannot go in any further
(Fig. 6B). Pull tube to confirm secure connection. Note: To remove tubing
from the fitting, press the collet in with two fingers while pulling tube out
Fig 6C). Without pressing the collet, the tubing will stay locked in
position.

Step 5: Installing the supply valve
The self-piercing supply valve (1008-1) can be installed on copper or CPVC rigid
plastic pipe of 3/8" to 1" diameter. NOTE: If your piping is PEX or any other softer
material, DO NOT USE this supply valve as it can cause a water leak. For PEX, you can
purchase appropriate fittings at the same store where you purchased this unit or you
can order the supply valve kit (model CK514) online directly from
www.rainfreshstore.com
IMPORTANT: Before you install supply valve, confirm the cold water pipe by running
hot water through your kitchen faucet. Touch both pipes under the sink to verify cold
water pipe and turn off the faucet.
Orient saddle valve with outlet threads pointing towards INLET (marked by grey
collet and arrow pointing towards it).
Back off handle on saddle valve to retract piercing tip. Make sure
piercing tip is flush with or slightly protruding from rubber gasket as
shown in Fig. 7. If it is sticking out too far gently push it against
something flat to push it back in flush with the rubber gasket.
Unscrew the bolts to separate the back plate from the supply
valve.
With rubber gasket in position clamp entire assembly (Fig 8) to
pipe using bolts provided. Tighten bolts, keeping brackets parallel
until rubber gasket is firmly compressed. CAUTION: DO NOT
OVERTIGHTEN. Do not turn handle yet.
Measure and cut remaining length of ¼” plastic tubing to connect
saddle valve to INLET AcculinkTM fitting. To connect ¼” tube to
the saddle valve, slide compression nut (726-0) and compression sleeve (1008-3) onto tube and put tube
insert (1603) into tube as shown in Fig. 8. Tighten compression nut (720-0) securely with a wrench.
Push the other end of the ¼” tube into the INLET fitting on the unit as shown in Fig. 6B.
Step 5: Start up
Reconnect QCA cartridge on the head below the inlet fitting (left side of unit) and QLV cartridge on the
other head (right side of unit), (lock position) (see Fig 9).
Turn the faucet handle to ON position.
Turn saddle valve handle clockwise. After some free rotations, the needle on the valve will start to pierce
the pipe. Continue to rotate the handle until it can go no further. You have now pierced the pipe, but the
valve is closed. Now turn handle counter clockwise all the way to open and start water flow.
Close faucet and check all connections for leaks. Carefully retighten any leaking fittings. It is a good idea
to check the unit a few times for slow leaks shortly after installation.
Flushing and conditioning: Allow water to flow from the faucet for 10 minutes to flush unit before
beginning service.
YOUR UNIT IS NOW IN OPERATION.
Note: Some carbon fines may persist for several days and the water may also appear milky because of trapped
air bubbles coming out of the unit. These are harmless and frequent running of the unit will clear them more
quickly. Running the unit for extended periods of time will NOT help.

Step 6: Setting the Cartridge Life Monitor (Model QS2 only)
Press and hold black monitor button. The orange LED will glow and after 5 seconds it will
blink 4 times and turn off. Now release the button as the monitor has been reset. The
monitor tracks both the gallons used and time. When either 375 gallons or 6 months have
expired the orange LED will blink every 5 seconds advising you to replace the cartridge. The
LED will continue to blink until monitor is reset as above. Note: Excessive sediment may cause
more frequent filter cartridge replacement.
(E) MAINTENANCE
1) Replacing Filter Cartridges (Models QCA and QLV):
For best results, both cartridges should be replaced at the same time.
For model QS2 –Replace both cartridges every 375 Gal or 6 months.
For model QS2X - Replace both cartridges every 250 Gal or 6 months.
The end of filter life is signaled by the orange LED blinking every 5 seconds.
Note: Filter cartridge life depends on water quality. Excessive fine sediment can
substantially reduce the filter cartridge life. This will be signaled by a sudden drop in
water flow or no flow from the faucet before the 6 month life is up. If your water has
excessive sediment, we recommend installing a Rainfresh whole house water filter available from the same
retailer where you purchased this unit. Call Rainfresh for assistance in locating a retailer and product
selection.
Note : There is no need to shut water off for cartridge change.
To replace filter cartridge - simply hold the cartridge and turn
about 1/4 turn left and lower it away from head while holding
it vertically to retain water. Empty the old cartridge in the
kitchen sink by holding it upside down and discard. Use a dry
absorbent cloth or a paper towel to wipe off any water that
may fall on the cabinet floor. To install new filter cartridge, turn
it to the right until it stops turning and the lock marks on the
cartridge and head line up (lock position). The cartridge is now
locked in place.
2) Monitor Battery: After approx 2 years yellow LED will blink
every 5 seconds advising you to change battery. To replace
battery - Remove head cover insert (2718) by gently pulling
away the insert from the head. Insert new battery (2545) into
battery slot between contacts with + side out and reattach cover insert to head assembly.
3) To test battery: With faucet off, press the black button for two seconds or less. If the orange LED lights up
then power is on and monitor is working. If LED does not light then battery is expired and must be replaced.
NOTE: If faucet is on and water is running, LED will not light if button is pressed.
4) Winterizing: Caution: If your unit is not used in winter, or will be subject to freezing temperatures, drain
unit and remove cartridge. Place cartridge in sink or on a paper towel to dry, which will occur in several days.
5) Cleaning: Clean with warm water and a soft cloth. CAUTION: Do not clean unit 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

(F) TROUBLESHOOTING
PROBLEM
SOLUTION
Saddle valve is leaking
1) Turn valve handle clockwise to shut water off
2) Make sure that the ferrule and sleeve is correctly installed as per fig 8
3) Fully tighten the compression nut to make sure seal is made
4) Turn valve handle counter clockwise to start water flow
5) If problem persists, call Rainfresh for assistance
Flow rate is very slow
after installation of unit
You may not have pierced the water pipe fully. Turn valve handle clockwise all
the way until it can go no further to make sure that valve needle has fully pierced
the water pipe.
Call Rainfresh to review installation procedure
There are some black
fines in the water
Some carbon fines may persist for several days. These are harmless and frequent
running of the unit will clear them more quickly. Running the unit for extended
periods of time will NOT help.
Water appears milky after
installation or after
replacing cartridges
Water can appear milky after a new cartridge is installed because of tiny air
bubbles coming out. These will clear out if you leave the water standing for a few
seconds and are harmless. After a few days of use the bubbles will slowly clear
away.
The cartridge came
undone from the head on
it’s own
This may indicate high water pressure or water hammer conditions exceeding
100 psi . You may need to install a pressure regulator (set at 60-70 psi max) and
a water hammer arrestor on the line. Call Rainfresh for further assistance
The faucet continues to
drip even after shut-off
1) Replace faucet cartridge
2) Call Rainfresh to order ceramic disc cartridge kit (1050-2)
Monitor does not light
up when I press the
button
If water is not running through the system and the monitor LED does not light
up, you may need to replace the battery (2545). Call Rainfresh to order

(A) INTRODUCTION
Votre système d’eau potable Twist de Rainfresh fait appel à un procédé de
filtration sophistiqué à deux étapes pour vous procurer une eau propre, sûre et
bonne au goût. Il réduit la chloramine, le plomb, les composés organiques volatils
(COV), les sporocystes, le chlore, le mauvais goût et les mauvaises odeurs
(consulter la fiche de rendement pour de plus amples renseignements). Le
système est conçu pour être installé sous l’évier de la cuisine et comprend un
robinet à disque en céramique.
* Les contaminants réduits par ce filtre ne sont pas nécessairement présents dans votre eau.
Le système « Twist » vous permet de remplacer facilement la cartouche, sans outil
et sans avoir à couper l’eau. Le système comporte un dispositif électronique
(modéle QS2 seulement) qui surveille la quantité d’eau filtrée et la durée en service, et fait clignoter un témoin
orange dès que l’une des limites est atteinte, vous indiquant qu’il est temps de remplacer la cartouche.
(B) CONSIGNES DE SÉCURITÉ
Ce système de filtration a été conçu pour un usage résidentiel à l’intérieur uniquement. Protégez le filtre
de la lumière directe du soleil.
Si la pression de l’eau dépasse la pression maximale de 100 po2, il est conseillé d’installer un régulateur de
pression et des antibéliers avant le filtre pour prévenir les chocs préjudiciables qui pourraient être
causés par une pression trop élevée.Le réglage recommandé du régulateur est de
75 psi/5,1 bar/517 kPa ou moins. Système de filtration non destiné à être installé dans des bâtiments de
plus de quatre étages.
Ne pas exposer à des températures inférieures à 0 °C lorsqu’il y a de l’eau à l’intérieur du système. Si vous
n’utilisez pas votre système en hiver ou s’il est exposé à des températures inférieures à 0 °C, videz-le (voir
la section « Entretien » pour plus de détails).
Ce système est destiné à être utilisé uniquement avec de l’eau froide. NE PAS L’INSTALLER POUR L’EAU CHAUDE.
Utilisez uniquement des cartouches filtrantes Rainfresh TWIST avec ce dispositif. Aucune autre
cartouche filtrante ne fonctionnera avec ce dispositif.
Ne pas lubrifier la tête des joints toriques avec des lubrifiants à base de pétrole. Le silicone alimentaire
(composé Dow 111) peut être utilisé de façon modérée.
Ne pas nettoyer le carter de filtre avec des solvants organiques, tels que ceux utilisés dans les aérosols
pour les produits de nettoyage ou les insecticides, car ceux-ci peuvent provoquer des fissures ou des
craquelures et entraîner des dysfonctionnements et des fuites.
L’installation de ce système peut impliquer des écoulements d’eau. Garder à portée de main une bonne
quantité de serviettes en papier ou un chiffon absorbant.
