Ideally, as with all pool equipment, the controller should be installed out of
direct weather. The service life of the Oasis SmartChem will be longer if it
is not exposed to direct sunlight and rain.
Before installing, and turning on the Oasis SmartChem system, take a sample of
your Pool/Spa water to a pool store and have it tested to ensure that the
Pool/Spa system is properly balanced. See below for recommended pool chemical
ranges;
CHLORINE: 1 – 3ppm TOTAL ALKALINITY: 80 – 150 mg/L PHOSPHATE FREE: (0)
pH 7.2 – 7.8 CALCIUM HARDNESS: 90 – 300 mg/L TOTAL DISOLVED SOLIDS: Below 1500ppm
Always take a sample of your pool water away from the return jets to ensure as
accurate reading as possible.
Always store Pool Chemicals in a well-ventilated position, at least 1.8M away
from your pool equipment to prevent fume build-up and causing corrosion of
your pool equipment.
When mixing acid with water, ALWAYS ADD ACID TO WATER. NEVER ADD WATER TO
ACID. If you add water to acid, it will violently react (creating heat and
boiling) and you may be splashed with acid. Wear protective equipment such as
Gloves and Face Shield when diluting the acid.
Only use diluted Acid, never use concentrated Acid. ACID should be diluted
with water within the range of 1 part Acid to 1 part Water (1:1) to 1 part
Acid to 2 parts Water (1:2). Dilute the acid in a well ventilate area and have
running water ready. In case of spillage, wash down area immediately. Always
seek medical advice if breathing is affected or an Acid Burn occurs.
NEVER MIX CHEMICALS. Store your pool chemicals in containers that are visibly
different by either colour and or size. Poisonous Gas can be produced if you
mix chemicals. Always store chemicals in accordance to the relevant Dangerous
Goods Codes and Standards.
It is highly recommended that you check your Water Chemistry (especially the
pH and Chlorine levels) regularly, either with a quality test kit or at your
local pool store to ensure that the Oasis SmartChem is working correctly, to
ensure there are no malfunctions, and to ensure that the pH and ORP sensors
are reading correctly.
It is highly recommended that before you install the Oasis SmartChem system,
that you sit the probe/s in your pool water for 24hrs. This will help the
probes to give a more accurate reading from the time of installation and will
help with the longevity of the probes.

2. GENERAL OVERVIEW
Congratulations on your recent purchase of your Oasis Aquatics SmartChem
system.
Please take a moment to read through the entire manual before installing your
new unit. Your Oasis SmartChem system must be installed and operated as
specified.
While every effort has been made to ensure that the information contained in
this guide is accurate and complete, no liability can be accepted for any
errors or omissions. Oasis Aquatics Pty Ltd reserves the right to change the
specification of the hardware and software described herein at any time
without prior notice.
Thank you again for choosing an Oasis Aquatics Smartchem system. We wish you
many happy years of swimming in your crystal clear pool.
INTRODUCTION
The Oasis SmartChem is designed to monitor and automatically adjust the pH and
Chlorine (ORP) levels of all types of Pools & Spas while the filtration pump
is running.
Once the pH and ORP levels have been set in the Oasis Smart App, the Oasis
SmartChem will automatically dose Pool acid (when it is required) to maintain
the set pH level. The Oasis SmartChem will also maintain the systems ORP by
either turning the Chlorinator On or Off, or by automatically dosing Chlorine
if you prefer Liquid Chlorine or are utilising an Ioniser.
The pH number is a measurement of how Acidic or Alkaline your Pool/Spa systems
water is. As close the 7.0-7.8 is almost neutral so it’s not harmful to
swimmers. To much acid (low pH) will cause the surface of the pool to degrade
quicker.
The ORP is a measurement of Chlorine activity (Oxidising properties) in your
Poo/Spa systems water and is measured in millivolts.
It has been ascertained that a Pool system with an ORP reading of 650Mv will
eliminate E-coli type bacteria in about a second. The lower the ORP reading,
the longer it will take for the bacteria to be eliminated from the system. An
ORP reading of 550Mv will mean that it could take up to 2hrs for the bacteria
to be eliminated.
IMPORTANT THE OASIS SMARTCHEM IS NOT DESIGNED TO BRING THE POOL/SPA SYSTEM
INTO
BALANCE; IT IS DESIGNED TO MAINTAIN A BALANCED SYSTEM.
Make sure your pool water is well balanced with the correct pH, Total
Dissolved Solids (TDS), Calcium Hardness levels and is Phosphate free.

App Setup
If you not already completed the latest Firmware Update through the Oasis
Smart App, do so now to be able to continue further with the Chemical Setup.
See pg 9 of the Oasis Smart Quick Start Guide for instructions on how to
complete the Firmware Update.
Updated App Menu
When you have updated the Firmware of your Oasis Smart system and completed
the Controller Connection, you will see 2 new options in the App menu.
The first one is Chemical Balance.
The second new option is Chemical Setup. You will not be able to set either
your pH level or your ORP level without first going into the Chemical Setup
menu option first.
Chemical Setup
When you go into the Chemical Setup option in the menu you will see this
display. The first thing that you will need to do, is tell the Oasis SmartChem
system what sizes your pool and spa are. Simply tap on the figure beside Pool
Size and then scroll either up or down to the figure that best represents the
size of your pool, and press OK. Note: If the size of your pool is in-between
2 pool sizes, select the size that is closet. For example; choose the Pool
Size of 55,000L if your actual pool size is 53,500L. Do the same for your Spa.
Note: If you don’t have a spa, then the option to choose the Spa size won’t be
displayed. Once you have set your Pool size (and Spa size if you have one),
tap on the red buttons beside pH Sensor and ORP Sensor (will turn Green) to
activate them.
Oasis SmartChem – INSTALLATION AND OPERATION MANUAL
Page 9 of 22
Chemical Setup (continued)
After you have activated both the pH and ORP Sensors the Oasis SmartChem will
display this.
· You will be able to adjust the pH Offset. The Offset allows you to adjust
the reading of the probe. Your probe may be reading pH at 7.7, but after
proper testing of your pool water the actual reading may be 7.6. You would
then adjust the Offset to -0.1.
· The reading in brackets below the Offset is your current pH reading. · The
pH Set Point is the level of pH that you would like your Pool/Spa
system to be running at. You can either tap along the line anywhere or tap and
drag to adjust the Set Point to where you would like it to be. · You will also
need to tap the button beside Acid Dosing to activate/deactivate the Acid
Dosing Pump attached to the side of the Oasis SmartChem controller. · The Acid
Dosing button will generally be left On. The only time you might turn it off
would be if there is a problem with the pump, you are changing over the acid
bottle/tub or if you have run out of Acid.
The same functionality applies to the ORP Sensor.
· The Offset will allow you to adjust the reading of the probe either higher
or lower. This will in turn effect when chlorination is called for, either
delaying chlorination or increasing its frequency.
· The reading in the brackets is your current ORP reading. · You will tap and
or slide the Set Point to set what Level of ORP you would like your system to
run
too. · When the Probe Settle Time is turned on, no dosing is done for the
first 30 minutes after the
circulation pump is turned on. If it is turned Off, dosing will commence as
soon as the pump starts.
Notes:
· Acid is only dosed when the pH reading is higher than the pH Set Point. If
the pH reading is above 8.5 then acid will not be dosed. You will need to
manually add acid.
· The pH Offset will only allow adjustment of up +1.5 or -1.5 points. ·
Chlorine is added/dosed only when the ORP reading is below the ORP Set Point.
If the reading is
below 300mV then Chlorine won’t be dosed, and you will need to manually add
chlorine. · The ORP Offset will only allow an adjustment of +150mV to -150mV.
Oasis SmartChem – INSTALLATION AND OPERATION MANUAL
Page 10 of 22
Chemical Balance
The other new menu option is Chemical Balance. (See the App Menu on page 7)
· In this menu option you will be able to adjust your set levels for both pH
and ORP. Both of these levels can be adjusted by either dragging the set point
or by tapping along the Set Point line.
· Underneath the Set Point line will be displayed what the Acid Pump is doing.
For instance (as displayed to the right); the Acid pump is in its waiting
cycle after dosing, to take a future reading to see if it needs to dose again.
It is also displaying the last time that it dosed.
· The Prime button allows you to cycle the Acid Dosing pump for 10 seconds to
get the pump primed and to ensure that it is working. After you press the
priming button, it will give you a 10 second count to let you know how much
time is left for the priming cycle.
The following is displayed on the App Home Screen. There is only a limited
amount of information displayed in regards to the Chemical Balance
information. It displays whether the pH is Low, Normal or High. The ORP will
also display whether it is Low, Normal or High. On the right-hand side of the
box there is a plus (+) symbol that when tapped, will allow the Chemical
balance window to be expanded.
Once the Chemical Balance display window is expanded, the window displays the
following. With the pH highlighted, the Chemical Balance window will display;
- Whether the pH is Low, Normal, or High. 2. What the actual pH level is
currently. 3. What the Set Point for pH is set to achieve. NOTES:
· A low pH reading indicates that the pool water has become Acidic. This can lead to skin and eyes being irritated during swimming.
· A high pH reading indicates that the pool water has become Alkaline. This makes it harder for the Chlorine to kill the germs in the pool water.
Oasis SmartChem – INSTALLATION AND OPERATION MANUAL
Page 11 of 22
Chemical Balance (continued)
When ORP is highlighted, the Chemical Balance window will display; 1. Whether
the ORP is Low, Normal, or High. 2. What the actual ORP level is currently. 3.
What the Set Point for ORP is set to achieve. NOTES:
· A low ORP reading indicates that the pool water may be carrying live and
potentially dangerous germs that could make swimmers ill.
· A high ORP reading could lead to swimwear being bleached and could also
irritate the skin and eyes of swimmers.
Diagnostics
If your Pool/Spa systems water is not balanced correctly, you may see the
following on the home screen of the App.
What the Oasis SmartChem is displaying is the following;
1. The pH reading is outside of the systems reading range of 5.5 to 8.5. If
the reading is lower than 5.5 (<5.5) or higher than 8.5 (>8.5), the controller
won’t dose Acid and will display CHECK in the pH box. If the system is
displaying CHECK, you will need to take a sample of your pool water to your
local pool shop and get it tested and add the amount of Acid or Buffer
required to get the pH level back to where it needs to be (7.2 7.8).
If the system is displaying —, it indicates that there may be a fault with the
probe itself or indicates an invalid reading.
2. The ORP reading is outside of the systems reading range of 300mV to 800mV.
If the reading is lower than 300mV (<300) or higher than 800mV (>800), the
controller won’t Chlorinate and will display CHECK in the ORP box. If the
system is displaying CHECK, you will need to take a sample of your pool water
to your local pool shop and get it tested and either;
a. add the correct amount of Chlorine required to get the ORP level back to
where it needs to be (about 650mV), or
b. stop chlorinating the pool for a certain amount of time to allow the
chlorine level to lower. If the Chlorine level is to high, a Chlorine Reducer
chemical can be added to the pool to reduce the Chlorine level.
If the system is displaying —, it indicates that there may be a fault with the
probe itself or indicates an invalid reading.

Probe Cleaning
pH Probe
The cleanliness of the sensor and junction is critical for an accurate
measurement. Drift (Offset) and a slow reading response are often due to an
unclean sensor or junction. DO NOT use abrasive materials to clean the probe.
The IH40 is supplied with a white cleaning tool. It can be used instead of the
tissue/cotton detailed below. Simply put some of the cleaning agent in the
tool and use this to clean the membrane.
· To remove inorganic deposits and scale o Soak membrane in dilute HCl for an
hour. Wash well with water and condition in 20% KCl solution before use.
· To remove solids and organics o Wipe the membrane with cotton or tissue
soaked in mild non-alkaline detergent. Wash with water and condition in 20%
KCl before use.
· To remove strongly adsorbed and chemically bonded impurities o Use a non-
abrasive cleaner such as JifTM undiluted on a soft cloth. Clean the pH
membrane, rinse with water and condition in 20% KCl before use. In the case of
protein contamination use 5% Pepsin in 0.1M HCl solution.
HINT: Calibrate the pH probe regularly. The frequency of calibration will
depend on the level of accuracy desired. When calibrating, always use fresh
buffer solution.
ORP Probe
The cleanliness of the sensor and junction is critical for an accurate
measurement. Drift (Offset) and a slow reading response are often due to an
unclean sensor or junction. DO NOT use abrasive materials to clean the probe.
· To remove inorganic deposits and scale: o Soak sensor tip in dilute HCl for
an hour. Wash well with water and condition in 20% KCl before use.
· To remove solids and organics: o Wipe the sensor tip with cotton or tissue
soaked in mild non-alkaline detergent. Wash well with water and condition in
20% KCl before use.
· To remove plated metals from ORP tips. o Soak the tip in approximately 0.1M
nitric acid for 15-20 minutes, followed by conditioning in 20% KCl.
HINT: Clean the electrode periodically. Unclean sensor tips are a very common
source of error in ORP measurements.

Replacing The Squeeze Tube The first thing that you will need to do is open
the App Menu and go into Chemical Setup. When you are is the Setup menu you
will need to turn the Acid Dosing button to the Off position. This will stop
the peristaltic pump from operating while you are replacing the Squeeze Tube.
Remove the tubing from the Intake and Output sides of the Peristaltic Pump. To
replace the squeeze tube of the Peristaltic pump, you will need to remove the
head cap (green cover). To remove, put your thumb under the lip at the bottom
of the head, gently but firmly lift the cover.
The head cover will come off to expose the squeeze tube and the head.
The pump head can be pulled out (the squeeze tube will come with it) and a new
squeeze tube can be wrapped around the head, and the head re-installed onto
the motor shaft. Ensure that you apply some appropriate, silicon-based
lubricant onto the pump head and the squeeze tube. Once the lubricant has been
applied, the head cover can be re-installed. Ensure that the squeeze tube is
seated properly. Re-attach the tubing running from the bottle and running to
the dosing manifold, making sure that both are clean and clear. Once re-
installed, ensure that you go back into the Chemical Setup menu in the App and
turn the Acid Dosing button back to the On position and prime the dosing pump
as per page 9 of this manual.

5. SYSTEM TROUBLESHOOTING
If you suspect for any reason your Oasis SmartChem system is not performing or running as it should be, here are some handy troubleshooting tips that may assist you.
The first thing to do is test your Water Chemistry with either a good quality test kit or take a sample of your pool water to your local pool store and have it tested.
Fault Indication pH is too Low
pH is too High
Remedy Excessive fresh water added to the pool (through either rainfall or topping up the pool with fresh water) which dilutes the Total Acid level. Adjust pH level as directed by your local pool shop. pH probe not reading correctly Clean and or Re-calibrate probe or adjust probe Offset (as per pg 8). pH Set Point is set to Low Adjust pH Set Point to appropriate level (7.2 – 7.8). Filter run time/s aren’t sufficiently long enough to ensure appropriate dosing rates Lengthen filter run time/s. Acid dosing bottle/tub is empty Re- fill bottle/tub with diluted acid at the appropriate ratio. CAUTION Always add acid to water when diluting, NOT water to acid. Dosing acid is over diluted Re-dilute the acid at a ratio closer to 1 part acid to 2 parts water. pH probe not reading correctly Clean and or Re-calibrate probe or adjust probe Offset (as per pg 8). pH Set Point is set to High Adjust pH Set Point to appropriate level (7.2 – 7.8). Manual Overdosing of Chlorine (Shock Treatment) Maintain pH Set Point. It may take a period of days to weeks or the pH reading to drop return to normal levels. This depends on how large the Overdose (shock treatment) was. The Oasis SmartChem will continue to operate normally during this time. Dosing pump is not operating as it should – Check the following; Acid dosing pump is working Press the Prime button (as per pg 9) and confirm pump works. Check for a blockage at the Injection point Remove the injection tubing from the Injection Point, check/ensure the tubing is clean and clear. If not, clean/trim the end of the tubing and reattach. Air leakage Check all connections to ensure they are tight and no air leaks are occurring. If any connections look suspect, trim the tubing and re-attach. Acid Dosing container is air tight If the dosing container is air tight, it won’t allow any liquid to be pumped from the container. Ensure appropriate container lid is fitted and the connection points are clean and clear. Dosing pump squeeze tube is leaking Squeeze tube needs replacing. Check to ensure that no water is returning to the Dosing container. Replace the Check valve (non-return valve) if there is water returning to the dosing container. If there is no Check Valve installed, please install one.

Chlorine is too Low Chlorine is too high
Filter run time/s aren’t sufficiently long enough or Chlorinator output isn’t high enough Lengthen filter run time/s or increase Chlorinator output. Make sure Chlorinator is working. Filter requires a back wash Back wash filter. Stabiliser (Sun Block) level is too Low (Outdoor Pools) Adjust level of Stabiliser to appropriate level Note: The need to run Stabiliser in an outdoor pool may be reduced if your Chlorinator is sufficiently sized to produce enough chlorine to negate the use of Stabiliser, ie the bigger the chlorinator the lower the stabiliser level needs to be. pH level is too high Adjust pH level to correct level (7.2 7.8). ORP probe not reading correctly – Clean and or Re-calibrate probe or adjust probe Offset (as per pg 8). ORP Set Point is set to Low – Adjust ORP Set Point to appropriate level, 700mV. pH level is too high Adjust pH level to correct level (7.2 7.8). Total Dissolved Solid levels are too high The only way to decrease the Total Dissolved Solids (<1500ppm) level of your pool is to introduce fresh water to dilute the pool water. Give your Filter a really long backwash to drop the level of your pool (by the amount recommended by your pool shop) and re-fill with fresh water. Stabiliser (Sun Block) level is too High (Outdoor Pools) Adjust level of Stabiliser to appropriate level (30-50mg/L). As per above. Note: The need to run Stabiliser in an outdoor pool may be reduced if your Chlorinator is sufficiently sized to produce enough chlorine to negate the use of Stabiliser, ie the bigger the chlorinator the lower the stabiliser level needs to be. ORP probe not reading correctly – Clean and or Re-calibrate probe or adjust probe Offset (as per pg8). ORP Set Point is set to High – Adjust ORP Set Point to appropriate level, 700mV. Manual Overdosing of Chlorine (Shock Treatment) – Maintain ORP Set Point. It may take a period of days to weeks or the ORP reading to drop back to normal levels. This depends on how large the Overdose (shock treatment) was. The Oasis SmartChem will not continue adding chlorine during this time period.

6. FURTHER INFORMATION
· Should power be interrupted for any reason, the controller will resume
normal operation when power is restored.
· Degree of protection against moisture: IP33.
· Store pool chemicals safely, at least 1.8 metres away from all pool
equipment.
· MAX combined rated input load for the JVA socket is 24Vac at 1.2Amps.
· The pool size and the proximity to the pH & ORP Set Points determines how
long (in seconds) the pump will actually dose for.
· The length of time between one dose of acid and the next is approximately 30
minutes. This gives the pool water a chance to mix properly and create a true
reading before the next dose is administered. This helps to ensure that
overdosing doesn’t occur.
· The pH dosing pump will inject the acid into a spa for either 2 or 4 seconds
per dose. The amount of dosing time will depend on the size of the spa.
· The pH dosing pump will inject acid into a pool at a time range of between 4
and 50 seconds per dose. The amount of dosing time will depend on the size of
the pool. The larger the pool, the longer the dosing time.
· On the Home screen of the Oasis Smart App, pH readings will only be
displayed of a value between 5.5 to 8.5. If the reading is outside of this
range, the App wil display either, <5.5 (check), >8.5 (check), or -(check).
· The Smartchem will be able to read a pH range of 0 (strongly acidic) to 14
(strongly alkaline) but any reading outside of the 5.5 to 8.5 range will only
be displayed in the Chemical Setup option of the menu.
· ORP readings on the home screen of the Oasis Smart App will only be
displayed where the value is between 300 to 800. If the reading is outside of
this range, the App wil display either, <300 (check), >800 (check), or
-(check).
· The Smartchem will be able to read a ORP range of 0 (little to no Chlorine)
to 1000 (possibly over chlorinated) but any reading outside of the 300 to 800
range will only be displayed in the Chemical Setup option of the menu.
· In the Chemical Balance window on the home screen of the Oasis Smart App,
the status text will display whether the pH or the ORP readings are Low’, High’, or Normal’ in comparison to the Set Points for both. · If for either the pH or ORP levels,—‘ is displayed, this is indicating a
missing/faulty probe or an invalid reading. A water sample test is advised at
this point.
· The Sensor & Injection Manifolds suit 50mm pipe, 4 reducing bushes will be
required if you are installing the manifolds into 40mm pipe
· If the pool system is to shut down for a lengthy period of time (eg; repairs
to the pool surface), it is recommended that the pH & ORP probes be removed
from the Injection Manifold and be stored appropriately. This involves putting
storage fluid (20% KCI) into the small bottles the probes came in, putting the
probes into the fluid, and screwing the nut to the top of the bottle. o If you
don’t remove the probes and put the pH & ORP probes into the storage solution,
the probes may be damaged and they won’t be covered under warranty.

· If you are storing liquid chemicals (Chlorine & Acid) in the same location,
it is advisable to keep these chemicals stored in visually different
containers, whether by colour and/or size, ie Liquid Chlorine in a 15L blue
container, and Liquid Acid in a black container or clear 5L container.
· If concentrated pool acid and chlorine are mixed together outside of the
pool water, they will produce a poisonous gas.
· The Oasis SmartChem is not designed to bring the Pool/Spa system into
balance; it is designed to maintain a balanced system. If you need to balance
your pool system before installing the Smartchem, add the pool chemicals
slowly and carefully allowing an appropriate interval of time for the added
chemicals to properly mix throughout the pool system. Continue testing and
adding chemicals until the pool system becomes balanced. o If you add large
quantities of chemicals quickly, you may overdose the pool water. It may then
take weeks for the pool water to remove these chemicals through natural
dispensation and return to a balanced state.
· Make sure that the squeeze tube in the peristaltic pump is lubricated every
6 months and for optimum performance replaced every 12 months. When
lubricating the tube, only use an appropriate silicone based lubricant. DON’T
use a petroleum based lubricant as damage may occur to the tube which may lead
to the tube leaking and premature replacement of the tube which won’t be
covered under warranty.
· If you are doing any work on the Oasis SmartChem peristaltic pump , tubing,
or probes, be sure to deactivate Acid Dosing (see Chemical Setup page 9 of
this manual).
