Important Safety Instructions

When mixing acid with water, ALWAYS ADD ACID TO WATER. NEVER ADD WATER TO ACID.
Always wear the appropriate safety equipment specified by the acid supplier when handling acid.
The system uses a 1 : 3 Acid : Water mix ratio (e.g. with a 20 litre drum add 15 litres water then 5 litres acid). It is important to use this mix for the correct acid volume to be added.
DO NOT PLUG UNIT IN IF CARTON HAS BEEN WET.

When using the CX Logix:

• Observe all applicable local, state, and federal safety regulations.
• Take proper precautions with prescribed environmental and operational conditions.
• Consider chemical compatibility with all wetted materials.

GENERAL OVERVIEW

Congratulations on your recent purchase of your Oasis CX Logix controller.
Please take a moment to read through the entire manual before installing your new unit. Your CX Logix controller 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. Crystal Aquatic Systems reserves the right to change the specifications of the hardware and software described herein at any time without prior notice.
The pH in your swimming pool will slowly rise due to factors such as alkalinity, the addition of fresh water and as sanitiser is produced in a salt/mineral water system. A rise in pH reduces the effectiveness of the sanitiser, so it is important to ensure that the pH remains in the correct range.
The pH of the water can be lowered by the addition of hydrochloric acid – and if your system has the optional pH control, this can be done automatically. The CX Logix controller uses an algorithm to calculate how much how much acid needs to be dosed to correct the pH.
Note: While the algorithmic pH control is effective, it does not measure pH. pH testing should be undertaken manually on a weekly basis to ensure the pH is correct.

SPECIFICATIONS

NOTE Certain specification may change without notice for reasons of improvement or better performance.

MAINTENANCE

Whilst this pH controller is built from the best engineered practices and material, please ensure you regularly undertake the following basic maintenance:
Injection Point on Injector Valve
Check the injection point periodically, by looking through the CLEAR faucet tee, for build-up of solid matter at the end of the clear flexible PVC tubing. This could only occur from contaminants in your acid container and the result is a blockage hindering the flow of acid and reducing the life of the pump tube and roller block. While unscrewing the BLACK lock nut, take care not to lose the rubber O-ring.

Lubricate Squeeze Tube
Lubricate the pump squeeze tube every 3-6 months. Use a silicone-based lubricant only as petroleum-based lubricants will cause damage to the tube and rollers.

Replace Squeeze Tube
Depending on usage, the squeeze tube may need replacement after 1-2 years of use. Before replacing, please ensure that the suction and injection tubes are empty. To change the squeeze tube, please follow the instructions included with the replacement kit. Only use our original sized commercial grade Tygon® Norprene® tube as incorrect sizing will result in early failure of the Tri Roller Block.

HELPFUL HINTS

• Read and keep your manual in a safe place.
• Test your swimming pool water on a regular basis and take your pool water sample to your local pool professional at least twice a month.

CONTENTS

TOOLS NEEDED

POOL PREPARATION

Please ensure that your pH is balanced to the recommended level for your swimming pool surface.
Ideal pH Levels:

A pH of 8.0 makes your chlorine only about 26% efficient so that is why it is critical to keep your pH in range. A correct pH level must be maintained to prevent problems such as black spot, staining, cloudy water etc. An incorrect pH level can damage the surface finish and walls of your pool.
When pH is high you can add Hydrochloric Acid to lower the pH. When pH is low you can add sodium bicarbonate (soda ash) to increase the pH.

---|---|---

STEP 1 Remove the contents from the box and carefully plan all steps using the installation diagram, and by reviewing the steps below.
STEP 2 Position the CX Logix controller box as indicated in the installation diagram, ensuring it is NOT too close to other equipment or power outlets, but close enough to the Oasis Chlorinator power supply so the piggy- back power cord can plug in to its socket outlet.
STEP 3 Attach the CX Logix controller to the wall by removing the simple “Click ON – Click OFF” wall mounting bracket that is attached to the controller case. Use the wall plugs and screws provided.

This unique design keeps the controller case unexposed to any possible water entry.

STEP 4 Fit the CLEAR faucet tee c/w injection valve to the pool water line, avoiding high pressure areas (i.e., after the pump, filter, and prior to heat pump). It can be installed prior to the cell housing (or after if needed).
STEP 5 Cut and connect a length of clear flexible PVC tube that will reach from the outlet at the base of the peristaltic pump (right side) to the injection valve, that is mounted in the CLEAR faucet tee, using the tube nut to secure the tube.
STEP 6 Do not cut the other length of clear flexible PVC tube yet. Place the acid drum (with the required mix) in the required position, in a ventilated area, preferably not near this or other pool equipment (at least 2m or more away), as the acid is corrosive and equipment damage will occur.
The system uses a 1 : 3 Acid : Water mix ratio (e.g. with a 20 litre drum add 15 litres water then 5 litres acid). It is important to use this mix for the correct acid volume to be added.
Important Safety Instruction: When mixing acid with water, ALWAYS ADD ACID TO WATER. NEVER ADD WATER TO ACID. Always wear the appropriate safety equipment specified by the acid supplier when handling acid.
STEP 7 Pass this clear flexible PVC tube through the drum label and a 6.0mm hole in the acid drum vent cap. Connect the clear flexible PVC tube to the suction valve that is mounted to the drum weight, using the tube nut to secure the tube. Before placing the tubing into the drum, measure the tubing against the outside of the drum and measure the feed tubing so that there is sufficient tubing. Lower the drum weight into the acid drum and screw on the drum cap.
STEP 8 Connect the pH Signal Cable with 5 Pin Plug to the Oasis CX Premium Salt & Mineral Chlorinator programming cable port. This is where the signal from the chlorinator comes from to turn the pH controller ON & OFF.
STEP 9 Connect the piggy-back power cord to the AC socket outlet of the Oasis CX Premium Salt & Mineral Chlorinator and the pool pump plugs in to the other end of the piggy-back socket.
STEP 10 Start up your pool pump and check the system for any leaks. Repair any such issues.
STEP 11 Prime the acid feed lines and finalise run settings using the menus below.

NAVIGATING THE LCD pH MENUS ON YOUR SANITISER

As fresh water is added, or chlorine is produced the pool pH will slowly increase. This can be offset by adding small doses of acid to the pool automatically. This pH controller uses a maintenance free algorithm that calculates the amount of acid, per dose, that is needed to maintain the pH.
Initially it is based on the size of your pool, but through your testing, it can smartly be adjusted to make it truly near-maintenance free for you the owner.
NOTE: It is important that the system is initially adjusted based on pH result to suit your pool and that pool pH is still checked regularly.

Accessing the pH Control Menu
These are the menus on the Oasis CX Premium Salt & Mineral Chlorinator On the power pack press OK to access the Main Menu system and use the +/- buttons to scroll through the menu until the LCD reads ‘pH Control Mode’.

TROUBLESHOOTING

If you suspect for any reason your Oasis CX Logix Controller is not performing or running as it should be, here are some handy troubleshooting tips that may assist you.

See Manual Section 10.1
pH controller power cord not plugged in| Check that power cord is plugged in to the sanitiser AC socket outlet
No demand for it to turn on from the sanitiser| The demand takes place each day at the start of T1 ON time or 8am (if no T1 ON time set).
Check if signal for pH required is ON.
Demand signal is present but
peristaltic pump is not turning| Contact your service agent
6.2 Everything displays correctly but pH level is not changing when testing
pool water| Acid drum is low or empty| Check acid level and replenish if necessary
6.3 pH controller is not running when sanitiser is in auto mode| The pH controller has already operated in today’s timer cycle| The pH controller will not run again if it has
already completed its automatic cycle
6.4 pH controller is running but the pool pump is not on| Pump is not plugged in or there is a problem with flow| The system should automatically stop when the pool pump stops but check that there is not a closed valve and that all pool equipment is plugged in and working
properly
6.5 pH Controller tri-roller is turning but acid is not pumping| Air leaks on the squeeze tube, injector tube or suction tube due to potential breaks| Check the tubes for damage or leaks and repair such or replace tubes
Excessive wear on the squeeze tube| Order a replacement squeeze tube kit and replace the tube
Excessive wear on the tri-roller black| Order a replacement tri-roller block assembly and replace the entire tri-roller block
6.6 Water flow returning from pool to the acid drum| In the unlikely event of this happening,|  it can only be one of two things:
Worn/damaged injector sleeve| Replace the injector sleeve
Worn tri-roller block| Replace the tri-roller block
6.7 pH level in the pool is too high or too low| Incorrect pH run time| Adjust pH run time to suit as per procedure in 10.2
Incorrect ACID:WATER mix| The system uses a 1:3 mix ration.
Ensure you have this required mix
Incorrect ACID DEMAND amount entered| You should only enter the required acid, not thew mix. So, if you need 500ml only enter this. The system allows for the 1:3 mix.
