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;

1. 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).
