PRECAUTIONS
REVERSE OSMOSIS MEMBRANE DIAGRAM
• Do not install the unit where the source/inlet pressure may be more than 80 psi or
there are excessive water hammer/spike problems. If your inlet pressure is more than
80 psi, install a 3/8" pressure regulator (HL 10071 see pg. 15), available at your
dealer or through HydroLogic.
• Keep out of direct sunlight or high intensity lights, which degrade the housing and
ttings over time. For added protection use the Algae Block Sleeve (HL 26009 see
pg. 15) to protect from sun or lights.
• When replacing lter cartridges, use the lter wrench to remove housings. Do not use
the wrench to tighten the housings. Hand-tighten the housings only. Take care not to
over-tighten.
• Do not install where leakage or failure may cause damage to property.
• If you are going to store or not use your for an extended period of time
(2 weeks+), remove your membranes, seal them in plastic and put in refrigerator.
• Protect unit against freezing to prevent cracking of the lter housings and water
leakage.
• Replace both clear pre-lter housings every three years: HL 23165 from your local
dealer or from HydroLogic.
• Do not drop or place heavy objects on top of unit.

ChloraShield®
Protect your roots! Many cities are switching to chloramines
as their primary method of disinfection. Chloramines are
most commonly formed when ammonia is added to chlorine
to treat drinking water, making it harder to remove. While
our Green Coconut Carbon lters work great for chlorine,
the smaller molecule size of chloramines requires additional
ltration to ensure your root-supporting microbes are happy
and healthy.

Note: Chloramines are a disinfecting agent that is being added by some
cities to the water supply in place of, or in addition to, chlorine. They are
a much more stable form of chlorine and do not dissipate from letting
the water be exposed to air or bubble out with an airstone. They cause
the same damage to all living things as does chlorine. Manufacturers
of carbon block lters, such as the one that comes standard with the
smallBoy, do not make specic claims for chloramines removal. If you are
sure your water supply contains chloramines, you can completely remove
them by upgrading the standard carbon lter to our
carbon lter.

A: The system comes with 1:1 red and 2:1 purple Flow Restrictors which determine the
wastewater to puried water ratios. The 2:1 (purple tubing) Flow Restrictor will give you the
best trade-off between membrane life and wastewater. If you have relatively low Parts Per Million
(PPM) source water or desire less wastewater you can choose to use the included 1:1 (red
tubing) Flow Restrictor.
Warning: The red 1:1 Flow Restrictor reduces wastewater and can lead to reduction in the
membrane life. The higher the source water’s PPM, the shorter your membrane life will be.
USE AT YOUR OWN RISK if the source water is above 300 PPM.
B. Once you have chosen the Flow Restrictor, install it into the Flow Restrictor/Flush Kit Assembly
(push both ends of the Flow Restrictor all the way into the open quick connect ttings). Note: The
Flow Restrictor tubing can be installed in either direction.

C: Next take the Flow Restrictor/Flush Kit Assembly and install it on the system by pushing the short
piece of pre-installed black tubing on the Flow Restrictor/Flush Kit Assembly into the open black
quick connect tting on the ASOV.
Note: When starting up the system for the rst time, make sure that the blue valve an the Flow
Restrictor/Flush Kit Assembly is in the open position (parallel with tubing). In order to ush the carbon
pre-lter properly, run for 2–3 minutes and discard all water. It is recommended to power ush the
system once a week for 5 minutes. This will help remove scale build up on the membrane.
D:Once the initial ush is complete turn the blue valve on the Flow Restrictor/Flush Kit Assembly
to the closed position (perpendicular to the tubing). THE BLUE VALVE SHOULD BE IN THE
CLOSED POSITION FOR NORMAL OPERATION.

Be sure the Flow Restrictor/Flush Kit Assembly’s blue valve is open (handle is parallel with tubing,
see gure E). Next, slowly turn the source water on until both the Carbon and Sediment lters have
water in the housings. Once both pre-lter housings are full, open source water up all the way (do
not exceed 80 psi). Power ush the system for 2–3 minutes when the system is new and/or when you
replace your carbon lter. Next, close the blue valve and continue to ush the membrane for 30–45
minutes. This will ush out the food grade preservative in the membrane.
After the initial 30–45 minute ush, turn the inline shut-off valve (pre-installed on the blue puried
water line) to the off position (perpendicular to the tubing). This will shut the water off on both the blue
and black lines, and pressurize the system. This is a good way to make sure that all the ttings and
connections are secured properly and that there are no leaks. It is also a good way to make sure that
the ASOV is working properly, meaning the black drain line is also shutting off shortly after the blue
line shuts off. If there are problems of any kind please contact HydroLogic directly at 888-426-5644
Note: It may take up to 24 hours of running the system for the PPM of the puried
water to stabilize at the lowest rejectiion reading.

Connecting QC Fittings:
Push tubing rmly into the tting, all the way until the tube stops. The collet (gripper) has stainless steel teeth
which hold the tube rmly in position while the O-ring provides a leak proof seal. Pull tubing to check for
security. If some tube pulls out, then push it all the way in again until it stops. It is good practice to test the
system prior to leaving site and/or before use.
Disconnecting QC Fittings:
Ensure system is depressurized before removing ttings then push in the collet evenly against the face of
the tting. With the collet held in this position the tube can be removed by simply pulling. You can use a
collet release tool (HL 24010, available from your dealer). The tting can then be re-used. If the tubing
has been removed several times you may see score marks on the ends, and this can lead to leaks. It is
best to cut the end off of the tubing with a sharp blade, being careful to cut straight across. Any angle to
the cut can cause a leak.

It is essential that you change your pre-lters regularly. The Green Coconut Carbon lter has a
rated life of approximately 1,250 gallons*of puried water produced. The Sediment lter can be
cleaned at your faucet or with a garden hose as often as you like. You should change the Sediment
lter at least every 6 months.
*2,000 gallon lter life with KDF85/Catalytic Carbon upgraded lter
Dirt can become embedded in your pre-lters and cause slower ow rates. To rinse the pre-lters,
use the included lter wrench to loosen the clear pre-lter housings. Be careful not to over-tighten
when reinstalling. It is preferable to hand-tighten lter housings.
The Reverse Osmosis membrane has a useful lifespan of 6 months to 2 years depending on how
high your source water PPM is, if there are high levels of certain contaminants (such as iron &
silica), how much water you produce and regular pre-lter maintenance. If your water is highly
contaminated, then you may need to change the membrane more often. If your water is relatively
clean and you keep up with your pre-lter changes, they may last 2 years+.
There are two indications as to when to change your membrane:
1. PPM rejection %: Test the RO product and source/inlet water to see what % of the inlet
water’s PPM the is ltering out (rejection %). You should see approximately 98%
of the inlet PPM being removed when the membrane is new. If the rejection % falls under an
acceptable level (typically 90%), it’s time to change the membrane.
2. The ow rate of the product water slows down signicantly. This can also happen if your
pre-lters are clogged. If you change your pre-lters and the product water still ows slowly,
this is an indication you need a new membrane. When in doubt, contact HydroLogic at
888.426.5644 or email us at [email protected].
STEP 1:
1. Remove the white ¼"
tubing from the membrane
housing.
2. Next, pull that same end
of the membrane housing
straight up to release it from
the clip.

Important Information & Performance Parameters
Reverse Osmosis is the most efcient and cost-effective way to remove the majority of all
contaminants from your water. The key component of the system are the RO membranes composed
of tightly wrapped sheets of a semi-permeable material. Under pressure, the membrane allows
pure water to pass through it and rejects, or ushes away, most impurities down the drain. That is
why all RO systems have a certain amount of wastewater. The ratio of wastewater is determined
by the Flow Restrictor installed in the Flow Restrictor/Flush Kit Assembly. The system comes with
a choice of 1:1 and 2:1 Flow Restrictors. Refer to pg. 7.
The ow of puried water is determined by the GPD rating of the membrane, inlet pressure
and inlet temperature. The has the capacity to produce 150 gallons per day
(approx. 6.25 gallons/hour when your inlet water is at 77°F, 60 psi, 500 PPM). If your inlet
pressure is less than 60 psi, you may experience less than the rated 150 GPD ow rate. A
minimum of 40 psi is required to operate the system. The higher the inlet pressure, the better the
ow. A booster pump is available as an option in case of low pressure and is necessary if your
pressure is below 40 psi (HL 29020 see pg. 15).
You will notice that in colder areas or in the winter, when water temperatures
are lower, the ow rate will be slower.
Inlet water that is very high in total PPM or very hard with calcium or magnesium, or high
in certain contaminants such as iron or silica, may shorten the life of the membranes and/
or cause slower ow rates. The RO membranes can handle inlet water up to 1,000 PPM and
with a hardness up 10 grains per gallon (170 PPM). Note that this is considered both very
contaminated and very hard water and may result in a shorter membrane lifespan. At these
levels of contamination and hardness, and especially beyond, you may consider pre-treatment
in the form of a water softener or other equipment. Softened water can be run through your
system for optimal performance. The membrane in the is capable
of removing 99% of salts that are introduced by the softener. Contact HydroLogic for more info
at 888-426-5644.
All RO systems exhibit “TDS creep. ” The rst few ounces of RO water produced
are higher in PPM than after the system has run for a few minutes. Take any
PPM readings a full ve minutes after turning the system on to ensure accuracy.
