IMPORTANT WARNINGS
This manual contains important information about the installation, operation and safe use of this
product. This information should be given to the owner and/or operator of this equipment.
When installing and using this electrical equipment, basic safety precautions should always be
followed. Failure to follow safety warnings and instructions in this manual can result in serious injury
and/or damage to your equipment. Read and follow all warning notices and instructions which are
included in this manual.
The PowerSupply internally contains live components. There is a danger of electric shockif opened.
If the power cord is damaged then it should be replaced by the manufacturer, their agent or similar.
To reduce the risk of injury, DO NOT permit young children to use this product unless they have
been trained by the person responsible fortheir safety and they acknowledge their ability to use such
equipment. To reduce the risk of accidents or incidents, service on the unit should onlybe performed
by your local pool Professional.
Ideally, aswith all pool equipment,the controller shouldbe installed out ofdirectweather.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
pH 7.2 - 7.8
TOTAL ALKALINITY: 80 - 150 mg/L
CALCIUM HARDNESS: 90 - 300 mg/L
PHOSPHATE FREE: (0)
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.

DO NOT CONNECT POWER TO THE OASIS SMARTCHEM UNTIL ALL THE
FOLLOWING CRITERIA HAS BEEN MET.
•Take a sample of your pool water to a pool shop, have it tested and have balanced your pool to
the appropriate ranges as specified on pg1.
oAlways take a sample of your pool water away from the return jets to ensure an accurate
reading.
•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.
DO NOT CUT ANY PIPEWORK TO FIT THE MANIFOLDS BEFORE TURNING ANY
FILTRATION, CLEANING, CIRCULATION OR HEATING PUMPS OFF.
You will need to leave them off for a period of time to ensure the glue used to connect the
manifolds has had the appropriate time to dry and bond properly to achieve correct pressure
rating.
The Sensor & InjectionManifolds suit 50mm pipe,4 reducing bushes will be required if you are installing
the manifolds into 40mm pipe.
•The pH and ORP probes and the appropriate Sensor Manifold have been installed into the
pipework (see the diagram below).
oThe pH and ORP probes will be inserted into small bottles of solution. It is advised that
you keep these bottles (after rinsing them out) for long term storage capability of the
