Overview
Thank you for your purchase of a state of the art Premier ZeroWaste®Reverse Osmosis Water Treatment System. Water
quality concerns are becoming more of a focus for the public. You may have heard about contaminants in the drinking
water such as Arsenic, Chromium, Cryptosporidium or Giardia. There may also be some local water issues such as high
levels of Lead and Copper. This Premier water treatment system has been designed and tested to provide you with high
quality drinking water for years to come. The following is a brief overview of the system.
About Reverse Osmosis
Osmosis is the process of water passing through a semi permeable membrane in order to balance the concentration of
contaminants on each side of the membrane. A semi permeable membrane is a barrier that will pass only certain par-
ticles like clean drinking water, but not other particles like arsenic and lead.
Reverse osmosis uses a semi permeable membrane; however, by applying pressure across the membrane, it concen-
trates contaminants (like a strainer) on one side of the membrane, producing crystal clear water on the other. This is
why RO systems produce both clean drinking water and rinse water that is flushed from the system. This reverse osmo-
sis system also utilizes carbon block filtration technology, and can therefore provide a higher quality drinking water than
carbon filtration systems alone
What Makes This Unit ZeroWaste®
Normally, reverse osmosis sends more water to the drain than what ends up as drinking water. This flushing is neces-
sary for reverse osmosis to work. This unit features a ZeroWaste®component that takes the water that would normally
be sent to the drain and redirects it into your hot water connection where it can be re-used.
The Stages of Filtration
Your system is a four stage RO which is based upon separate treatment segments within the one complete water filtra-
tion system. These stages are as follows:
Stage 1 – Sediment filter, recommended change 6 months.
The first stage of your RO system is a five micron sediment filter that traps sediment and other particulate matter like
dirt, silt and rust which affect the taste and appearance of your water.
Stage 2 – Carbon filter, recommended change 6 months.
The second stage contains a 5 micron carbon block filter. This helps ensure that chlorine and other materials that
cause bad taste and odor are greatly reduced.
Stage 3- Membrane, recommended change 2-5 years.
Stage three is the heart of the reverse osmosis system, the 50GPD (Gallons Per Day) RO membrane. This semi perme-
able membrane will effectively remove Total Dissolved Solids (TDS), Sodium and a wide range of contaminants such
as Chromium, Arsenic, Copper, Lead as well as Cysts, such as Giardia and Cryptosporidium. Because the process of
extracting this high quality drinking water takes time, your RO water treatment system is equipped with a storage tank.
Stage 4- VOC Block filter, recommend change 12 months.
Through the specialty (VOC) like MTBE’s, Atrazine, Benzene, 2,4-D,Lindane and others from your drinking water. It is
estimated that VOC’s are present in one-fifth of the nation’s water supplies. These water contaminants can enter ground
water from a variety of sources including localized use of herbicides and pesticides, gasoline or oil spills, leaking
underground fuel tanks, septic system cleaners, and chemicals used in the dry-cleaning industry. See performance data
sheet for individual contaminants and reduction performance.
Note: Filter & Membrane life may vary based upon local water conditions and/or use patterns.

BEFORE INSTALLATION
Cut the tube square. It is essential that the outside diame-
ter be free of score marks and that burrs and sharp edges
be removed before inserting into fitting.
Make certain to push the tubing completely into the con-
nector until it comes into contact with the internal tubing
stop. The collet (gripper) has stainless steel teeth which
hold the tube firmly in position while the O-ring provides a
permanent leak proof seal.
Pull on the tube to check that it is secure. It is good prac-
tice to test the system prior to leaving the site and/or
before use.
To disconnect, ensure the system is depressurized before
removing the tube. Push in collet squarely against the face
of the fitting. With the collet held in this position, the tube
can be removed. The fitting can then be reused.

System Maintenance
Just because you cannot taste it, does not mean that it is not there. Contaminants such as Lead, Chromium and Arsenic
are undetectable to the taste. Additionally, over time if you do not replace the filter elements, other bad tastes and
odors will be apparent in your drinking water.
It is important to change out your filters at the recommended intervals as indicated in this system manual. When
replacing the filter elements, pay special attention to any cleaning instructions. Should you have any further questions
please refer to our web site at www.premierH2o.com or call our customer service department at 1-800-752-5582.

Drill a Hole for the Faucet in a Porcelain Sink
NOTICE For Marble Counter-tops, we recommend contacting a qualified contractor for drilling a hole in a
marble counter-top.
Note: Most sinks are predrilled with 1½” or 1¼” diameter hole that you can use for your Drinking Water faucet.
(If you are already using it for a sprayer or soap dispenser, see Step 1).
NOTICE Porcelain sinks are extremely hard and can crack or chip easily. Use extreme caution when
drilling. Watts accepts no responsibility for damage resulting from the installation of faucet.
Diamond tip bit recommended.
Step 1: Determine desired location for the RO faucet on your sink and place a
piece of masking tape over where the hole is to be drilled. Mark the center
of the hole on the tape.
Step 2 : Using a variable speed drill set on the slowest speed, drill a 1/8“ pilot hole
through both porcelain and metal casing of sink at the marked center of
the desired location. Use lubricating oil or liquid soap to keep the drill bit
cool (If drill bit gets hot it may cause the porcelain to crack or chip).
Step 3: Using a 1.25” diamond tip hole saw, proceed to drill the large hole. Keep
drill speed on the slowest speed and use lubricating oil or liquid soap to
keep the hole saw cool during cutting.
Step 4: After drilling, remove all sharp edges and make sure the surroundings of the sink are cooled before
mounting the faucet.

OPERATION
Startup Instructions
WARNING
!To prevent the possibility of electrical shock, clean up any water on cabinet floor and dry all
water from outside of RO unit.
Congratulations! You have completed the installation of your new Reverse Osmosis system. Please
Follow the Startup Instructions.
Step 1: Turn on the incoming hot and cold water angle stop valves.
Step 2: Turn both of the adapt-a-valves on and check the system for leaks
and tighten fittings as necessary.
NOTICE If you have connected your RO system to a refrigerator / ice
maker, make sure the ice maker is off (do not allow water to
flow to the ice maker) until flushing (Step 9) is complete and
the tank has been allowed to fill completely. Connection from
the RO to the ice maker system should have an in-line valve
installed before the ice maker so it can easily be closed to pre-
vent water flowing to the ice maker during start up and peri-
odic maintenance. Your storage tank must be allowed to fill up
fully in order for the ice maker system to work properly.
Step 3: Plug the transformer into the electrical outlet under the sink.
Step 4: Make sure the ball valve on the tank is open
Step 5: Open the RO faucet and leave it open until water begins to drip. Then close the faucet. The tank will
take between 2 - 4 hours to fill.
NOTICE If the pump doesn’t start, make sure there is power at the electrical outlet and that it is not con-
trolled by the garbage disposal switch.
Step 6: After the tank has filled once, open the RO faucet and drain the tank.
NOTICE Water may be cloudy or milky due to air in the system and carbon particles flushing out of the
final polishing filter. This condition will resolve itself after flushing a couple of tanks of water.
Step 7: Complete step #6 two more times. The process of flushing the system first three times should take
about one day to complete. The fourth tank can be used for drinking water.
NOTICE Check daily over the next week to ensure no leaks are present.
NOTICE Flushing of the tank 3 times is only necessary during the initial startup and after replacing the
membrane.

MAINTENANCE
Changing the Filter Cartridges
Your RO module is equipped with valve heads which will automatically turn off the water supply to each filter when the
filter is released, thus you do not need to turn off the incoming water supply at the Adapt-a-Valve. The RO faucet must
be off when filters are replaced. To make the removal of the filter cartridges easier, the heads & cartridges may be
swiveled up to 90 degrees as shown in the pictures below.
6 Month System Maintenance
Replace: Sediment Filter (Red Label PN# 105311)
Carbon Pre-Filter (Yellow Label PN# 105351)
Annual Maintenance
Replace: Sediment Filter (Red Label PN# 105311)
Carbon Pre-Filter (Yellow Label PN# 105351)
VOC Carbon Post-Filter (Silver Label PN# 105381)
Tip: This is a good time to check the air pressure in your storage tank. For instructions please see page 12.
Step 1: Unplug the transformer from the electrical outlet
Step 2: Place a towel under the filters to catch any excess water that may drip
out from the filters during the changeover.
Step 3: To remove a filter cartridge: Push & hold the button on the valve head
above the filter. Pull cartridge downward (from the head) to remove.
Release button and discard old filter.
Step 4: To install a filter cartridge: Remove the seal cap and insert the cartridge
into the valve head until you hear an audible “click” (the button does
not need to be pressed to install new filters).
Step 5: If performing the annual maintenance, flush the first tank full after
completing the annual maintenance.
TIP: If the new filter cartridge won’t snap in easily or pops off, relieve
pressure to the system by turning off the water supply using the
adapt-a-valve and then install the cartridge. Once the cartridge is
seated, turn the water supply back on to your RO unit.
WARNING
!To prevent the possibility of electrical shock, clean up any water on cabinet floor and dry all
water from outside of the RO unit before plugging in the transformer.
Step 6: Plug the transformer back into the electrical outlet.
This reverse osmosis system contains a replaceable component (the RO membrane) which is critical to the effi-
ciency of the system. Replacement of this reverse osmosis membrane should be with one of identical specifica-
tions as defined by Premier to assure the same efficiency and contaminant reduction performance.

RO Membrane Replacement (2 - 5 Years)
Replace: RO Membrane - 50 GPD (Green Label PN# 105331)
Membranes have a life expectancy between 2 and 5 years, depending on the incoming water conditions and the amount
the RO system is used. This reverse osmosis membrane is critical for effective reduction of total dissolved solids (TDS).
The product water should be tested periodically to verify that the system is performing satisfactorily.
Normally, a membrane would be replaced during a semiannual or annual filter change. However, if at any time you
notice a reduction in water production or an unpleasant taste in the reverse osmosis water, it could be time to replace
the membrane. Premier recommends replacing the membrane when TDS reduction falls below 75%.
A water sample may be sent to Premier for a free diagnosis of your membranes performance. To send a water sample,
use 2 clean containers and fill 1/2 cup of tap water in one container and 1/2 cup of RO water in 2nd container. Clearly
label each sample. Send the samples to the address listed on the cover of this manual attention “Water Samples”.
Premier will test the water and mail or call you with the results.
Annual Sanitization
NOTICE Do not change your post-carbon filter until the sanitization has
been completed. The pre-filters and membrane can be changed
before the sanitization
Step 1: Turn off the water supply to your RO system at the adapt-a-valve and
open the RO faucet to drain the storage tank.
NOTICE If you have connected your RO system to a refrigerator/ice
maker, make sure the connection has been turned off. Do not re-
open the connection until the sanitization process is complete.
Step 2: Locate the tube that runs between your filter module and the storage
tank and disconnect at both ends.
Step 3: Drain any remaining water in the tube
Step 4: Hold both ends of the tube together with the ends pointed away from
your face. Using a dosing syringe (see figure) slowly insert 1 teaspoon
(5 mL) of common household bleach into the tube.
WARNING
!Do not use needle syringe
DANGER
!
IF BLEACH GETS IN EYES: Hold eye open and rinse slowly and
gently with water for 15 - 20 minutes. Remove contact lenses if
present, after the first 5 minutes, then continue rinsing eye. Call
a poison control center or doctor for treatment advice.
Step 5: While covering one end of the tube with your finger, insert the other
into the tank. Then insert the open end into the filter module.
Step 6: Turn the incoming water back on and let the system fill for
approximately 10 minutes
Step 7: Turn off the incoming water and let the system sit for 1 minute.

Step 8: Drain the system completely and then follow the startup procedure - filling then draining two full tanks
of water.
Step 9: Replace the post-carbon filter once complete.
Check Air Pressure in the Tank
NOTICE Check air pressure only when tank is empty of water!
Check air pressure in the storage tank when you notice a decrease in available water
from the RO system. Air can be added with a bicycle pump using the schrader valve
that is located on the lower side of the tank behind the blue plastic cap.
Step 1: Turn off the incoming water supply to the RO.
Step 2: Open the RO Faucet and allow water to drain from the tank until it is
completely empty.
TIP: When water from the RO faucet slows to a trickle, with the faucet
still in the open position, you may add air to the tank to purge
any left over water, this will ensure that the tank is completely
empty.
Step 3: Once all water in the tank is purged, check air pressure using an air pressure gauge, it should read
between 5 - 7 PSI. (Digital air pressure gauge is recommended)
Step 4: Follow startup procedure on page 10.

NOTICE Check daily over the next week to ensure no leaks are present.
Step 4: Plug in the transformer into the electrical outlet
NOTICE NOTE: If you have connected your RO system to a refrigerator / ice maker, make sure the ice
maker is off (do not allow water to flow to the ice maker) until the tank has been allowed to
completely fill.
Step 3: Open the RO faucet and leave it open until water begins to trickle out (it will come out slowly).
Step 4: Close the RO faucet allowing the storage tank to fill with water. It may take 2 to 4 hours to fill the tank
completely depending on the production capability of the membrane, local water temperature and water
pressure.
Step 5: After the Tank has filled, open the RO Faucet to flush the tank completely. You will know that the tank
is empty when the flow rate from the RO faucet is down to a trickle. The second tank can be used for
drinking.

Troubleshooting
NOTICE Before disconnecting any tubes, make sure to unplug the power then turn off the water valves
and depressurize the system
Problem Possible Causes Solution
1. Low/Slow Production Low Water pressure Incoming water pressure to unit must be at
least 40 psi.
Old adapt-a-valve If you have recently installed the system,
make sure any old adapt-a-valves, from pre-
vious systems, have been replaced
Crimps in tubing Check tubing and straighten or replace as
necessary
Clogged pre-filters Replace pre-filters
Fouled Membrane Replace Membrane. Make sure hot water
return has been turned on
Clogged Post-Carbon Filter Replace Post-Carbon filter
2. Milky colored water Air in system Air in the system is a normal occurance with
the initial start-up after RO installation or
filter replacement. This will disappear during
normal use within 1-2 weeks. If it continues,
check incoming water.
3. System is constantly running or
pump won’t turn off
Crimps in tubing Check tubing and straighten or replace as
necessary
Clogged pre-filters Replace prefilters
Fouled Membrane Replace Membrane. Make sure hot water
return has been turned on
Other Turn off the valve at the top of the tank and
check water production from faucet. The sys-
tem should produce at least 3-4 ounces (89-
118 mL) per minute with the tank off. If it is
producing less, check for clogged pre-filters
or a fouled membrane.
4. Pump won’t turn on No power at outlet Make sure the outlet is not controlled by the
garbage disposal switch. Switch to a differ-
ent outlet.
Electronic Connections are
loose
Make sure connections at controller and wire
harness are secure.
Transformer is burned out Make sure filters aren’t clogged which can
cause the pump to draw extra amperage and
burn out the transformer. Replace trans-
former.

5. Noise from pump Pump is vibrating against adja-
cent object
Make sure the pump is attached to the
bracket and standing on the rubber feet at the
bottom of the bracket. If pump is hanging on
wall, add padding (such as foam) between
bracket and wall to dampen vibration.
Pump is damaged Replace pump
6. Small amount of water in storage
tank
System is starting up Normally it takes 4-6 hours to fill tank. Note:
low storage tank incoming water pressure
and/or temperature can drastically reduce
production rate.
Low water pressure See Item 1
Air pressure in tank is too high Repressurize Tank - See Page 12
Low air pressure in tank Repressurize Tank - See Page 12
7. Low flow from faucet. Low air pressure in tank Repressurize Tank - See Page 12
8. Hot water from RO system System is too close to the hot
water heater
Make sure the system is at least 25 feet away
from the hot water heater.
9. Leak at Fitting Damaged Tubing Disconnect the tube (See Section “Using
Quick-Connect Fittings” at beginning of
manual) then cut about 1” from the tube or
replace tube and then re-insert. Replace tub-
ing if necessary.
Damaged Fitting Replace fitting
10. Unpleasant taste from water Tank needs to be sanitized Sanitize your system
Filters are Fouled Replace Filters
Filters weren’t removed prior to
an extended period of non-use
Replace filters and Sanitize your system
11. Leaking at faucet Faulty o-rings on lower faucet
assembly
Check o-rings. Lubricate o-rings or replace
lower faucet assembly if damaged.
12. TDS Levels are high Bad membrane or connection
to hot water outlet is off
The system flushes out the waste/brine water
to the hot water connection under the sink. If
this connection is turned off, that can foul an
RO Membrane and clog or cause higher TDS
levels.
