1.0 SCOPE AND GENERAL
The condition of water in each geographical location and water requirements of any feed water appliance are different, hence
attention is required before setting up Xsential’s QuadRO system. All RO systems should be installed by a qualify plumber
or technician. It is important that all installers read this manual and the appliance manual carefully before commencing
installation of Xsential’s QuadRO system. Any wrong installation and set up may result in serious damage to the appliance.
Xsential will not be held responsible for the incorrect installation and set up of the system.
1.1 Disclaimer
Xsential warrants that its reverse osmosis systems will reject up to 96% of salt. Specification of the requirements by individual
appliances may vary. It has been proven that all Xsential's reverse osmosis systems help prevent scaling. However, it is up to the
individual to check for compatibility of Xsential's reverse osmosis system for the intended application. Xsential will not be
responsible for any wrong installation or water configuration.
2.0 QUADRO QUICK CHANGE REVERSE OSMOSIS (R.O.) SYSTEM

3.0 SYSTEM COMPONENTS
The QuadRO R.O. system comes with the following components:
1. QuadRO system
2. An AX10-TS triple action system
3. A pressure reduction valve (A)
4. A ¼” male to 3/8” tube connector (B)
5. Two ¾” female to 3/8” tube reducers
6. A 3/8” tube union tee connector (C)
7. A 3/8” OD ball valve (D)
8. A storage tank (R)
9. A TDS meter
10. 2 meters of red 1/4” tube
11. 7 meters of 3/8” blue tube
4.0 PREPARATION FOR INSTALLATION
QuadRO should be mounted relatively near the appliance to maximise the flow rate and ease for service. The storage tank should
be located where it can be removed if necessary, but does not take away needed storage space. Make sure that the water
pressure is at least 350kPa or higher (recommended operating pressure is 400kPa or higher).
5.0 INSTALLATION INSTRUCTIONS FOR QUICK CONNECTOR
Remove all dust plugs from the quick connectors. To connect the poly tubing;
Diagram 2
CAUTION: To ensure proper assembly, tubing MUST be fully inserted into the fitting body until the tube stops.
1. Cut the tubing end squarely (with tube cutter)
2. Insert the tubing through the back of the connector all the way through the assembly until the tube stops in the fitting body (see
diagram 2).
6.0 INSTALLATION OF COLD WATER SUPPLY CONNECTOR
The water supply connector that comes with the unit is made up of two parts; a dual check pressure valve and a straight 3/8” OD to
¼” male connector. A cold-water supply ball valve should be installed next to the appliance. Install the pressure reduction valve
and the 3/8” OD to ¼” male connector as shown in diagram 3.
Diagram 3
WARNING: INADVERTENTLY CONNECTING THE UNIT TO HOT WATER WILL DESTROY THE MODULE AND VOID THE
WARRANTY. THE FEEDING WATER TEMPERATURE CANNOT EXCEED 40OC.
7.0 MOUNTING QUADRO REVERSE OSMOSIS SYSTEM
Look for the hole marking on top of the bracket.
1. Place the housing in the desired position.
2. Mark screw locations at the desired positions according to the marking and drill the holes.

1. Remove the black plastic cap on the bottom of the tank.
2. Tape the 3/8” male end of the cone reducer (item Q) with Teflon tape.
3. Tighten the 1” to 3/8” cone reducer (item Q) to the storage tank (hang tight only).
4. Tighten the 3/8” feed water ball valve to the reducer.
5. Measure the distance between the storage tank and the R.O. system.
6. Cut a 3/8” poly tubing with the length measured.
7. Unscrew the ball valve screw from the storage tank.
8. Insert the 3/8” poly tubing into the nut and tighten the screw to the ball valve (item P in Diagram 1).
9. Insert the other end of the tube to the position marked Tank on the QuadRO
10. Turn on the ball valve (blue handle should be parallel to the tube)
11.0 CONNECTING UP THE APPLIANCE
1. Screw the ¾” connector with 3/8” tube reducer on to both water inlets of the appliance
2. Measure the distance between the appliance and the QuadRO system and cut a 3/8” poly tubing with the length
measured.
3. Connect the tubing to the Quad RO at the position marked APP (location F in diagram 1).
4. Do not connect it to the steamer oven/coffee machine/appliance at this stage.
12.0 CONNECTING UP FEEDING WATER
1. Measure the distance between the water feed valve and the R.O. system
2. Cut a 3/8” poly tubing with the length measured
3. Insert the tube to the connector B as shown in diagram 1.
4. Insert the other end of the tube to the 3/8 tube union tee adapter (item C in diagram 1)
5. Insert one end of the union tee connector to the inlet of the Triple Action System (item M) as shown in diagram 1
6. Insert a tube to the outlet of the Triple Action System (item M).
7. From the outlet of the Triple Action system (item M), insert the other end of the tube to the RAW water inlet of the
appliance.
8. From the 3/8” union tee connector, insert the tube into the 3/8” OD ball valve of the QuadRO system (item D) as
shown in diagram 1
13.0 START UP PROCEDURE
1. With the tube that is connected at the position marked APP (location F in diagram 1), move the end of the tube to the drain
cup.
2. Turn on water supply slowly.
3. Check for leaks. (If anything is leaking shut off water, repair, then start with step 1 again.
4. Within a few minutes (up to 10 minutes) the water will start to flow from the tube connected at the position marked APP.
5. Let the water run for 15 minutes. This flushes out the preservative in the membrane.
6. Turn off the water supply.
7. See Section 14 if you wish to adjust the TDS/water hardness of the water.
8. Insert the end of the tube that is connected at the position APP into the soft water inlet of the appliance.
9. Turn on the water supply - the tank will take about 1-2 hours to fill up (depending on the size of the tank and water pressure).
14.0 ADJUSTING THE TDS (TOTAL DISSOLVED SOLID) OF THE WATER
Note: A TDS tester and water hardness test kit is required for testing the water hardness. The TDS tester is used as a guide only.
The water hardness test kit will be required to test the final hardness of the water. The default set up for the system is to reject up
to 96% of the impurities in the water.

Some appliances require a certain level of water hardness in the water in order to function properly. It is important that the installer
is aware of the water requirement specification of the oven before starting the installation. Any wrong setting may result in serious
damage to the appliance. Please contact the water appliance manufacturer for details of the water hardness.
Xsential will not be responsible for any wrong installation and set up of the QuadRO system.
1. After installing the QuadRO system. Make sure that the QuadRO system is not connected to the appliance.
2. Turn on the water supply.
3. Let the water run for 15 minutes as in section 12 step 5.
4. Measure the TDS (total dissolve solid) of the RO water with the TDS meter.
5. Increase/decrease the raw water supply to the required setting by adjusting the TDS adjuster.
6. Once the required TDS level has been achieved with the TDS meter test the water hardness of the water using the water
hardness kit.
7. Once the water hardness level is satisfactory, tighten the lower nut of the TDS adjuster. This will stop people from
accidentally adjusting the TDS.
8. Turn off water supply and connect the QuadRO system to the appliance.
15.0 SYSTEM MAINTENANCE AND FILTER CHANGE PROCEDURE
CAUTION FOR YOUR SAFETY: Change the sediment and carbon filters regularly every 4-6 months and have the R.O.
membrane checked annually. Refer to the following table for the recommended filter change interval.
1. Shut off the ball valve (item D in diagram 1) that is connected to the water supply.
2. Grab the cartridge that is to be changed with both hands and turn the cartridge anti-clockwise until it stops.
3. Pull the cartridge down to remove the cartridge.
4. Repeat steps 2-3 on the remaining cartridges.
5. All cartridges are labelled with a number on the top right hand corner. Use the correct numbered cartridge for the
replacement.
6. Insert and turn clockwise until the cartridge stops.
7. Once all cartridges have been replaced turn on the ball valve (item D in diagram 1).
16.0 XSENTIAL TROUBLE SHOOTING GUIDE

19.0 IMPORTANT NOTICE
Issues which can affect the water quality of RO systems
Xsential warrants that its reverse osmosis systems will reject up to 92-96% of salts in water.
The reverse osmosis (RO) technology has been around for many years and has shown that the technology provides
the best solution when it comes to the protection from scaling of water feed appliances. Such appliances include
combi-steamer ovens and coffee machines.
The use of RO systems have also been known to contribute to the extension of life of water feed appliances.
However, RO systems cannot prevent corrosion from occurring. RO systems will invariably remove the elements in
water that could contribute to corrosion thereby prolonging the life of appliances but corrosion can commence in any
number of ways. All corrosion issues should be investigated by a corrosion expert.
Below are some factors which can affect the warranty of our RO systems.
1. Water source: Australia’s water can come from dams, underground wells, desalination plants, or a mixture
of various sources. This results in an inconsistent quality of water whereby some water sources could have
more dissolved salts than others. For example underground sources of water have more dissolved salts than
water from a dam. Hence RO systems might not be suitable for use in some areas. Highly saline water can
affect the performance of Xsential’s RO systems. Please check the water quality with your local water
authorities.

2. Seasonality: The concentration of salts in water increases in some seasons due to lack of rainfall while in
other seasons, the water may be less saline.
3. Chemical treatment: The amount of chemicals used to treat the water e.g. chlorine, fluoride, etc can lead
to inconsistencies in the water quality. Water is treated periodically by the local water authority leading to
times when the water may contain high doses of elements that can cause corrosion.
4. Manufacturer’s water requirements: The requirements by individual water feed appliances such as combi
steamer ovens may vary from the specification produced by Xsential’s RO systems. The end user should be
made aware of this.
5. Wrong installation.
6. Wrong TDS/water hardness output adjustment.
7. Service interval: it is very important that all of Xsential’s RO systems are serviced regularly. Failure to
service (replace filter cartridges) regularly can cause the RO system to not function properly. See the
installation manual for details.
Although all care has been taken by Xsential to ensure that its RO systems perform according to its manufacturer’s
specification, Xsential cannot guarantee the performance of its water treatment systems due to factors which are
beyond its control. Some of these factors have been listed above. End users should be made aware of the factors
that could affect the life of water feed appliances.
