Uses 50% less water than traditional RO

systems

The GX150/GX200. When we developed the GX150/GX200, we decided to pack all the

high end features into a tight efcient RO unit. We engineered a 50% increase in water

production over traditional ROs, lowered the waste ratio to 2:1, and still offered it to you

for the same price point of an entry level RO lter. But we didn’t stop there. We topped it

all off with a 2” stainless steel liquid-lled pressure gauge, never before seen in a lter this

size, and integrated it into our patented GX Series bracketing system. A manual ush valve

allows you to clean the membrane, purging out pollutants that could otherwise add buildup

to the system. Flushing adds considerable life to the membrane. With ow rates at 6.25/9

GPH (Gallons Per Hour), the GX150/GX200 delivers the same excellent ltration as our

larger models.

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 Revers 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/GX200 and GX300/GX400 and an astounding 1:1 ratio 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 GX150/GX200 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

pressure 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.

Information on quick connect ttings

INSERT TUBE INTO FITTING

Push the tubing through the collet and dual o-rings until it bottoms out against the tube stop. The

collet holds the tube in place and the dual o-rings provide a leak resistant seal.

MAKE A CLEAN TUBE CUT

Cut the tube squarely and if using plastic tubing, ensure that the cut has not made the tube out of

round. Also ensure that the tube has a smooth outside diameter without any burrs or score marks

prior to inserting it into the tting.

TEST AND INSPECT

Push and pull the tubing toward and away from the tting to ensure that it has been installed properly.

Test and inspect the installation for any leaks.

TUBE REMOVAL

Relieve pressure from the tubing and tting. Push uniformly around the collet ange against the tting

body while pulling the tubing away from the tting to release it.

Growonix RO water lters use quick connect ttings that allow for easy maintenance.

Important Tips:

• Growonix 300 GPD water lters are designed to be used with between 40-80 psi of

incoming water pressure. Do not exceed 80 psi of incoming water pressure. If incoming

water pressure is too high, install pressure regulator before unit. Pressure regulators are

available at www.growonix.com

• Always turn incoming water pressure on slowly, allowing all air to be discharged before full

water pressure is restored.

Setup Instructions:

Connect the 1/4” blue drain tubing to

ow restrictor, making sure drain tubing

seats all the way in quick-connect tting.

This is the waste/drain tubing that will

also connect to the drain clamp.

Connect 1/4” white RO tubing to the auto

shut-o valve, making sure RO tubing

seats all the way in quick-connect tting.

This is the ltered RO water out line.

Connect 3/8” white supply tubing to the

inlet tting, making sure inlet line seats all

the way in quick-conect tting. This is the

supply water in line.

Mount drain clamp to available drain

pipe. Connect other end of drain tubing

to included drain clamp.

Connect the 1/4” blue drain tubing to the

tee tting just after the ow restrictor.

Important Tips:

• The GX150/GX200 water lters are designed to be used with between 40-80 psi of incoming

water pressure.

• Units upgraded with High Flow Membranes can work with as low as 20 psi of incoming

water pressure.

• Do not exceed 80 psi of incoming water pressure. If incoming water pressure is too high, in-

stall pressure regulator before unit. Pressure regulators are available at www.GrowoniX.com

• Always turn incoming water pressure on slowly, allowing all air to be discharged before full

water pressure is restored.

Connect 3/8” white supply tubbing to the

inlet tting, making sure inlet seats all

the way in quick-connect tting. This is the

supply water in line.

Connect 1/4” white RO tubing to the auto

shut-o valve, making sure RO tubing

seats all the way in quick-connect tting.

Setup Instructions

Replacing Sediment and Carbon Pre-Filters

Unscrew sediment and carbon lter hous-

ings using supplied lter wrench. Wash

inside of lter housings to remove debris.

Tighten lter housings by hand, do not

use lter wrench. Do not over tighten.

When replacing lter housings, make sure

housing O-rings are seated properly. O-

rings function best when lubricated with

food grade silicone lubricant.

Install new sediment and carbon lter,

making sure they go into the correct lter

housings.

Important Tips:

• Pre-lters should be changed when either brown discoloration occurs, or system ow

rates have signicantly declined.

• Always turn incoming water pressure o before servicing the unit.

• Always turn incoming water pressure on slowly, allowing all air to be discharged before

full water pressure is restored.

Sediment Carbon

Replacing Membrane Element

Disconnect input tubes from RO

membrane housing.

Unscrew membrane housing end cap.

Caps can be dicult to remove. Be sure to

have a rm grip on opposite side of hous-

ing . Do not lose O-ring on inside of cap.

Each cap has two O-rings.

Pull out membrane using needle nose

pliers or other similar tool.

Insert new membrane into housing,

making sure the membrane-end with

the two O-rings goes in rst. Make sure

membrane is completely seated in the

housing.

Replace end cap and tighten by hand. If

O-rings are dry, lubricate with food grade

silicone lubricant. Allow system to run for

½ hour before using RO water.

Important Tips:

• Membranes should be replaced

when system output signicantly

declines. Note: system output may

decline due to other factors as well

(see: troubleshooting)

Flushing the Membrane Element

After ushing is complete, simply turn

ush valve to OFF position. Membrane

has been ushed.

Let system run for 3-5 minutes.

Make sure valve is open

(in the ON position).

ush position

closed position

(RO on)

GrowoniX water lters come with a manual ush valve. Flushing the membrane element after each

use for approximately 3-5 minutes will remove standing salts from the membrane, signicantly ex-

tending membrane life. Even weekly ushes will improve membrane life and system performance.

The ush valve is located in 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, opening the ush

valve will start the system again in ush mode, and the membrane will be closed.
