sure the front support is seated on to the front oven horizontal frame evenly.
8.0 INSTALLATION OF WASTE WATER DRAIN AND PRESSURE RELEASE VALVE
The wastewater from the QuadRO system must be removed by allowing the wastewater to be drained away. This flow of the
waste water will assist in keeping the membrane free from mineral deposits and fouling. Cut the ¼” red tube to the length that is
required to connect the flow restrictor and the drainage cup. Insert the tube into a ¼” OD x ¼” stem elbow connector and insert it
into the drain connector of the QuadRO (location I in diagram 1) and secure the tube to the drainage cup.
Cut 80mm of the 3/8” tube. Insert the 3/8” tube into a 3/8” OD x 3/8” stem elbow connector. Insert the other end of the tube to the
3/8” OD x 3/8” OD ball valve. Insert the stem elbow into the TANK inlet of the QuadRO (J in diagram 1).
9.0 INSTALLATION OF AX12-WS WATER STABALISER SYSTEM
1. Measure the distance between the APP outlet and the AX12-WS filter head and cut the 3/8” tube according to the
measurement.
2. Insert the tube into the APP of the QuadRO and “IN” inlet of the AX12-WS filter
10.0 INSTALLATION OF STORAGE TANK AND QPB300 PUMP
NOTE: PRESSURE ADJUSTMENT IS NOT REQUIRED as the storage tank is shipped with pressurised air. The tank comes with
the stainless steel horizontal bracket. Put the RO tank on the shelf right behind the QuadRO system and the QPB300 pump right
next to the outlet of the tank. Do not plug in the power plug of the QPB300 at this stage.
1. Measure the distance between the QPB300 “From Tank” outlet and “OUT” of the AX12-WS filter and cut the 3/8” tube
accordingly.
2. Insert one end of the 3/8” tube to a 3/8” OD x 3/8” stem elbow connector and insert the connector into the “OUT” outlet of
the AX12-WS filter. Insert the other end of the tube to “From Tank” of the QPB300 pump.
3. Measure the distance between the QPB300 and the tank inlet Q in diagram 1. Insert one end of the tube to “To Tank”
connection of the QPB300 pump and the other end of the 3/8” tube to MIP hole plastic nut (Q in diagram 1) and screw on
the fitting.
11.0 CONNECTING UP FEEDING WATER
1. Screw the pressure limiting valve with dual check to the isolation valve.
2. Tape and screw the 3/8” OD x ¼” NPT male connector to the pressure limiting valve.
3. Measure the distance between the water feed valve and the “Water In” of the QPB300 pump.
4. Cut a 3/8” poly tubing with the length measured. Insert the one of the tube to the connector B as shown in
diagram 1 and the other end to a 3/8” OD x 3/8” stem elbow connector. Insert the stem elbow connector to the
“Water In” of QPB300 pump.
5. Measure the distance between the QPB300 “OUT TO RO” and the red sticker water filter 1 of QuadRO. Cut the
tube and insert one end of the tube to the QPB300 pump (Out to RO) and the other end to the first filter (red
sticker) of the QuadRO system. You may need to use 3/8” OD x 3/8” stem connector to ensure that the tubes
are not under any stress.
12.0 CONNECTING UP THE APPLIANCE
Please note that the ¾” hose for connecting the RO tank to the oven is not supplied. The oven comes with the hose. Connect the
connection “P” of the tank to the oven hose.
13.0 START UP PROCEDURE
1. Double check the connection of installation. Make sure the pressure release ball valve (J in diagram 1) is in ON position and
RO tank is in OFF position (M in diagram 1).
2. Plug in the power for the QPB300 pump
3. Turn on water supply slowly.
4. Turn on the power for the QPB300. The pump should start pumping within 2 second.
5. Within a few minutes the water will start to flow from the water pressure release valve J.
6. Check for leaks. (If anything is leaking shut off water, repair, then start with step 1 again.
7. Let the water run for 15 minutes. This flushes out the preservative in the membrane.
8. Turn ON the RO tank valve (M in diagram 1) and Turn OFF the pressure release valve.
9. The installation is done.
14.0 TOTAL DISSOLVED SOLID (TDS) CHECK
To check if the QuadRO system is working or not. Simply press the red button of the TDS meter. The system will show the TDS
reading “Before” and “After”. You should see there is a significant reduction in the TDS reading on the after end of the meter.

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. Turn off the power supply of the QPB300 pump.
2. Shut off the water supply isolation valve A from diagram 1 and storage tank isolation valve (M).
3. Grab the cartridge that is to be changed with both hands and turn the cartridge anti-clockwise until it stops.
4. Pull the cartridge down to remove the cartridge.
5. Repeat steps 2-3 on the remaining cartridges.
6. All cartridges are labelled with a number on the top right hand corner. Use the correct numbered cartridge for the
replacement.
7. Insert and turn clockwise until the cartridge stops.
8. Once all cartridges have been replaced turn on the isolation valves and follow by the power for the QPB300.

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 scale build up in water 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.
