In Aquarium Reef and Portable Reverse Osmosis (RO) Systems the higher the
capacity of the membrane (GPD) the better it is. Whenever it's possible we always
upgrade your system to a higher GPD membrane.

Operating Temperatures of System Components:
www.liquagen.com
Minimum Temperature: 39° F.
Between 39° F and 50° F the flow rate will be very slow.
This is the outside temperature not the home temperature.
Operating Pressure: Minimum 45 PSI (2.95 kg/cm2).
If the pressure is lower then 45 PSI you need to purchase a Low Pressure Membrane for
$25.00, which will give you 60 Gallons at 30 PSI. You can also add a Booster Pump which
will do the same for $90.00 (these are the costs we purchase the membrane/pump for from
the manufacturer directly).
Drinking Water Systems with a storage tank can still operate at 38 PSI. But for aquarium
and portable systems the PSI must be higher then 45.
Kindly let us know if you face any of the above problems so we can help find the most cost
effective solution.
These systems are delicate and occasionally get damaged during the shipping process. All
systems include extra connector elbows which are easy to replace.
Instructions to Replace Damaged Elbows
1. Take a pair of scissors and open them.
2. Push one side into the broken elbow and turn it anti-clock wise.
3. Put Teflon tape on the extra elbow which can be found in the box.
4. With your hand twist them on where the broken elbow was.
5. Do not tighten the elbows too much as they might break.
Please Note:
All systems include extra connectors (elbows) with blue clips.
After installing the system and before running water, kindly make sure all the
tubing is properly pushed in and secure by first pulling and then pushing all
the tubing in.
Tighten all canisters (housing) with the wrench before turning on the water
supply.
OPERATING PARAMETERS

SETTING UP YOUR RO/DI UNIT :
1. Connect the system to the incoming water supply.
2. Check that all connectors and tubing are properly tightened before letting any water
enter the system.
3. Flush the Membrane.
4. You now have ultra pure water!

The usage of each tube:
RED TUBE ~ Incoming Water
WHITE TUBE ~ Outgoing Water
BLACK TUBE ~ Waste Water
During shipping tubes become loose. It's important to check all tubing's are securely
in the system.
First pull and then push all the tubing's in. This will make sure the system has no leaks.
Water creates immense pressure that there is no way you can do it after the water is turned
on so it is crucial to check all tubing's Then switch on the incoming water line and again
make sure there are no leaks. Then close the incoming water line then put the blue lock on
all elbows (fittings).
Tighten all the canisters with the wrench
ST
FLOW RATE IS SLOW FOR 1 FEW DAYS BUT WILL GRADUALLY PICKS UP
Operating parameters:
1) RO System must be connected with caution!! Do not connect the RO System to
Municipal or well water source that freeze. The membrane contained is treated and tested
on regular water and will be destroyed if frozen. These are basis to insure bacteriological
safe water.
WARNING!! Do not plug the RO System to hot water. This will destroy the membrane
DOUBLE CHECK TO PREVENT ANY LEAKS BEFORE FLUSHING THE MEMBRANE.
Why Flush the Membrane?
It is important to flush the membrane because you don't want the Fine (powder) Carbon from the
lower filters to be left in the membrane and membrane housing. It clogs the membrane with the black
powder .It also increases the life of the membrane by 2 years.

The system is designed with a Manual Flush Valve. This helps ease the process of
flushing the system before usage.
After installing the system you need to flush the membrane for 20-30 minutes.
Directions:
1. The picture above shows the manual flush valve in the open position.
2. In order to flush the membrane the blue valve needs to be in the “open position.”
You should see an increase of water coming out of the black (waste) tubing.
3. Let the water flow for 20-30 minutes.
4. After flushing the membrane please turn the blue valve Off. It should look like the
picture below. Once this is completed your system is ready to be used!
Please Note:
·To maintain the supreme quality of water it's strongly advised to flush the system
every 4 months for 15 minutes To clean the membrane
·Don't forget to close the valve after flushing or the system will not work.

The following conditions for feed water supply must be met:
This Reverse Osmosis System is designed to operate at a water pressure in the range of 45 to
85 PSI. At pressures lower than 45 PSI the quantity as well as the quality of the water will be
reduced. At higher pressure, severe damage to the system may result. If local water pressure
Exceeds 95 PSI a pressure regulator must be installed which will reduce the water pressure into the
system. It is recommended that total TDS (Total Dissolved Solids) does not exceed 2000 PPM
FAQ'S
Q. I've flushed the system for 30 minutes but water is still flowing from the black
tubing.
A. First, please make sure the manual flush kit is in the closed position. Secondly, for every
gallon used the system rejects 3-4 gallons of water depending on the water quality,
outside temperature, and pressure. This is standard in all RO/DI systems regardless of
the brand. The rejected water is simply the waste water which is not fit to pass the
filtration phases.
This can be reduced by 80% after installing a Aquatec Patent Permeate Pump which
makes the waste water 1:1. Another option is to add another membrane depending on
your GPD. We recommend the permeate pump as it's the most cost effective solution in
the long run.
Q. How often should I flush the membrane?
A. We recommend every 4 months. This is done to protect the reverse osmosis membrane
(brain of the system) and save you tons of money by increasing the life of the system
and ensuring maximum filter life. The manual flush kit makes it 10x easier to do so as
you simply twist the valve instead of taking the system apart.
Q. When do I replace the filters?
A. Pre-Filters (Sediment/UDF/Carbon) -- 8-12 Months
RO Membrane -- 3 Years
Green DI Resin Cartridges -- 8-12 Months
*Please note these factors depend on the water quality, temperature, and PSI. The best
way to know is by checking when Stage 1 (Sediment) & the DI Color changing resin
starts turning brown.
We have cost effective replacement filters under "Filter Kits" designed specifically for
each RO/DI unit. Each system also has replacement part links on the product
description tabs.

Q. Why is water flowing slowly from my system?
A. Many factors can affect the flow of the water such as:
1. Low Water Pressure - The water PSI needs to be at least 45 PSI for the system to run
smoothly. You can find out the PSI by contacting your local water municipal center or
pressure gauge. This can be resolved by a low pressure membrane or booster pump.
2. Weather Condition - In extreme cold the system's flow rate may decrease due to the
outside water PSI decreasing. This can be resolved by a low pressure membrane or
booster pump.
3. Old Filters - When the filters get exhausted it takes longer for water to flow through
the system. The best way is to make sure filters are replaced in the proper time frame
ensuring 0 PPM water.
Q. Can I drink this water?
A. We highly recommend you do not drink 0 TDS water as it's too pure for human
consumption. For healthy drinking water you need some TDS & if you would like a
system for both drinking and aquarium use we recommend looking into our Dual Series
(Drinking + Aquarium).
