Our Mission
Durability, Reliability, Eciency, Purity, and Conservation form the foundation on which we design and build
all of our products. Consistent and superior quality sets us apart from other manufacturers and increases
our value to you - our customer. Whether you are a hydroponics hobbyist, serious enthusiast, or large-scale
gardener, GrowoniX is committed to bringing you the best solution for water purication systems.
What is Reverse Osmosis?
Reverse osmosis (RO) is a ltration method that removes many types of large molecules and ions from
solutions by applying pressure to the solution when it is on one side of a selective membrane. This ltering
process ensures that the solute (waste water) is contained within the pressurized chamber while the pure
solvent (RO water) is allowed to pass freely through the membrane.
Tuned for Growing - In Tune with Our Customers
Traditional RO systems have waste ratios of approximately 4:1, which means there are 4 gallons of waste
water produced for every 1 gallon of puried water. GrowoniX line of water lters achieve waste ratios of 2:1
with the GX150 and GX300 and an astounding 1:1 ration with the GX600 and GX1000.
GrowoniX has created a complete product line that will address the needs of hydroponic operations of all
sizes. Our lters will signicantly reduce your water use while dramatically increasing your yields.

Precautions:
• Do not use unit with inlet water pressure exceeding 80 psi. If inlet water pressure is too high, install
water pressure regulator before the unit. Regulators and pressure limiters are available at www.
Growonix.com or your local plumbing supply.
• Keep unit away from direct light. Direct light can cause algae and other biologicals to grow inside
of the lter housings.
• Do not install unit near electrical outlets or electrical devices. Do not install in places where a leak
can cause damage.
Information on ow rates:
GrowoniX GX300 and GX150 RO water lters are rated using supply water that is 77°F, 475ppm, at
70psi. Slower performance may be noted in areas with colder temperatures, higher water salinity, or
lower inlet water pressure.
• A minimum of 40psi is recommended to operate GrowoniX water lters. If your inlet water pres-
sure is too low, booster pumps can be used to increase pressure. Pumps are available at www.
Growonix.com.
• Do not use a ow restrictor other than the one included with your unit.
• Flow restrictors help tune the unit for proper waste ratio.
• Using bigger ow restrictors, or using the unit in areas with exceptionally dirty water, will decrease
membrane performance and longevity.
Pressure Guage Dierentials:
The table below displays pressusre guage readings that will assist you in knowing when to change
GXseries pre-lters. Pre-lters should be changed when the ouput pressure guage reads 30% lower
than input pressure guage (30% pressure dierential).
Input pressure gauge Output pressure gauge Pressure Dierential
80 56 30%
75 53 30%

Information on quick connect ttings:
Growonix RO water lters use quick connect ttings that allow for easy maintenance.
ENSURE TUBING HAS A CLEAN CUT
Make sure tubing end has a clean 90 degree cut. Make sure outside surface of tubing is free from
scratches, bends, or pitting.
INSERT TUBING INTO FITTING
Push the tubing through the collet and o-ring(s) until it bottoms out against the tube stop. The collet
has steel teeth which holds the tube securely in place. The o-rings provide a leak proof seal.
TEST THE SEAL
Push and pull on the tubing while seated in the tting to make sure that tubing is securely in place.
TUBING REMOVAL
Relieve pressure from the tubing and tting. Push collet into tting while pulling tubing out. Pushing
collet inward releives the grip that the collet teeth have on the tting, and allows the tubing to move
out freely.

Important Tips:
• Growonix 600/1000 GPD water lters are designed to be used with between 40-80 psi of in-
coming water pressure. Do not exceed 90 psi of incoming water pressure. If incoming water
pressure is too high, install pressure regulator before unit.
• Always turn incoming water pressure on slowly, allowing all air to be discharged from the
system before full water pressure is restored.
• It is recommended to ush the membrane upon initial startup. (see: Flushing Membrane Ele-
ment)
1
Mount drain clamp to available drain
pipe. Connect other end of drain tubing
to included drain clamp.
Make sure ush valve is in closed position
as shown above. This position is for the
normal operation of the RO lter.

nected to supplied adapter.
Setup Instructions:
Connect RO and waste / drain assembly
to membrane housing as shown. Make
sure tubing is seated completely into O-
rings of quick connect ttings.

Flushing The Membrane Element:
While the system is running, turn the
ush valve to the ON position.
Let system run for 3-5 minutes.

After ushing is complete, simply turn
ush valve to OFF position. Membrane
has been ushed.

Growonix GX600 and GX1000 water lters come with a manual ush valve. Flushing the mem-
brane element after each use for approximately 3-5 minutes will remove standing salts from the
membran, signicantly extending membrane life. Even weekly ushes will improve membrane
life and system performance.
The ush valve is located on the waste line of the RO membrane. To ush the membrane simply
turn the ush valve to the FLUSH position as seen in picture 1. High-pressure water will bypass
the ow restrictor and shuto valve and be sent down the drain, carrying membrane pollutants
with it. If using a oat valve and the system happens to be OFF due to valve engagement, open-
ing the ush valve will start the system again in ush mode, and the membrane will be cleaned.

Tighten housings with supplied lter
wrench. Close ush valve and begin
normal usage.
Growonix GX600 and GX1000 pre-lters should be changed regularly to ensure maximum mem-
brane element life and system performance. When a 30% dierential between the guages is
reached, pre-lters should be changed (Reference: Pressure Gauge Dierentail pg 2.)
The pressure dierential is really “pressure drop” caused by dirty pre-lters.
Install new sediment and carbon
cartridges, making sure sediment
cartridge is installed in the housing
closest to the input side of the unit.
Be careful not to lose the O-ring when
replacing lters.

Turn o incoming water supply. Open
ush valve to relieve system pressure.
Loosen pre-lter housings using supplied
lter wrench. Empty standing water and
remove old pre-lters. Clean interior of
housings to remove standing sediment
and debris.

• After replacing membrane turn incoming water pressure on slowly, allowing all air to be
discharged before full water pressure is restored.
Replacing Membrane Element:
1
Turn incoming water supply OFF and
open ush valve to depressurize the sys-
tem. Disconnect RO and drain lines from
output side of RO membrane housing.
Remove snap ring from both ends of
membrane housing.

Clean inside of membrane housing to
remove buildup or debris. It is recom-
mended to clean interior membrane
housing with mild bleach solution to rid/
prevent any biological buildup. Rinse
interior membrane housing with clean
water before continuing.
Seat O-ring back in output side of mem-
brane housing (see component diagram).
Make sure O-ring is lubricated with food-
grade silicone grease to aid with installa-
tion. Replace end cap on output side of
membrane housing.
