The appliance is not intended for use by young children or infirm persons without supervision. Please ensure that young
children are supervised to ensure that they do not play with the appliance.
Controller must be installed according to AS 3000 wiring rules.
If the supply cord is damaged it must be replaced by AstralPool or its service agent or a similar qualified person in
order to avoid a hazard.
This product is NOT suitable for use on Spa Pools UNLESS the OPTIONAL pH sensor has been purchased
and installed.
When used on Spa Pool applications, AstralPool strongly recommend the purchase and installation of a
chlorine sensor in addition to the pH sensor.
This product is NOT suitable for use on Indoor swimming pools UNLESS the pH and Chlorine sensors have
been purchased and installed.
The Viron e-Quilibrium can only be purchased through a professional pool business and MUST be installed
by that dealer.
Dose pool with a small amount of chlorine before starting the eQ. If no chlorine is sensed the eQ may go to
fail safe mode and not start up. Some Chlorine should be present before starting the unit.
Take extreme care when handling the pH adjuster which is either sulphuric acid or hydrochloric acid. Wear
gloves, eye protection and breathing protection.
Before installing probes, balance pool water. Total Alkalinity (TA) must be 80 to 120 ppm, Calcium Hardness
should be 180 to 250 ppm, and pH must be between 7.2 and 7.6.
Cyanuric Acid, sometimes referred to as stabiliser or sunscreen will suppress the Chlorine (ORP) reading
when the Chlorine sensor is connected. Refer to section on setting chlorine levels if Cyanuric Acid is present in
your pool.
Product is designed to run with ACID diluted to water to acid ratio of 2:1 should always be followed as the
machines dosing rate is formulated around the diluted solution. Using neat acid can lead to overdosing the pH level.

Introduction
Congratulations on your purchase of the Viron series Salt Chlorinator. The correct pH balance of your pool water
significantly increases the effectiveness of the chlorine in the water and if not maintained at the correct level, can cause
harm to the interior finish of your swimming pool or spa and reduce the disinfection time of the chlorine.
The purpose of the Viron eQuilibrium series chlorinators is to significantly reduce the level of daily and weekly maintenance
required to keep your pool and spa sparkling clean and healthy to swim in.
These installation and operating instructions will guide you through installation, operation and maintenance of your new
chlorinator. Regular maintenance will ensure many years of trouble free operation.

2.0 Installation Viron e-Quilibrium chlorinator
The Viron e-Quilibrium Chlorinator incorporates a controller with inbuilt acid pump, an electrode cell for converting
minerals or salts into chlorine, a mounting plate for the controller and tubes, weights and injection points for the acid which
controls your pool water pH. The intelligent software allows you to select and change your acid dosing ratio and
intelligently adjusts the dose rate to match the output of the electrode. (The higher the output, the faster the pH will
change and the more the controller will dose acid to compensate). However, you MUST test your pH every day for the
first week and adjust your acid dose rate on the controller to achieve the correct pH level.
2.1 pH levels:
Generally you should aim to have your pH at 7.4 to 7.8. The actual pH you choose for your pool will depend on the water
quality in your area, the interior finish of your pool and the type of pool you have.
2.2 Mounting the Controller:
Choose a location that is preferably out of direct sunlight, near the filter system. The controller should be located 1 metre
above ground level to prevent rain splash back or sprinkler system damage to the underside of the controller. The
controller must be mounted on a vertical surface/wall. If mounted on a post, a flat sheet 20mm larger than the controller
housing must be used.
a. Mount the wall bracket using the screws provided on a secure wall.
b. Glue sensing chamber for probe into plumbing line after filter and gas heater (if installed) but prior to chlorinator
cell. Sensor Chamber must be plumbed to ensure probe is horizontal to water flow.
c. Glue Chlorinator cell into line as per drawing below after filter, heater, solar (if installed) and after sensor T piece.
d. Plug the pH sensor into the underside of the controller in the location marked “pH”.
e. Plug filter pump 3 pin plug into underside of Controller.
f. Connect 4 wire cell cable ensuring matching colours.
g. Remove cap from pH sensor and screw firmly into sensor chamber installed in the plumbing. Do Not Over tighten.
h. The cell must be installed with the barrel unions underneath and the cell should be horizontal. Both 40mm and
50mm fittings have been provided. Make sure that the ‘o’rings are correctly fitted and the unions are done up
tightly. Flow direction through the cell is critical –refer to label on housing.
i. Hang Controller on wall bracket and plug power supply lead into 3 pin 10 amp outlet.

2.3 Connecting the PVC Acid Tube
PLACEMENT OF CHEMICALS, EQ CONNECTIONS.
Placement of Chemicals
***Chemicals MUST be stored apart in accordance with Relevant Standards and Dangerous Goods Codes. Consult
your authorized builder or pool shop technician for advice. Chemicals must be at least 1 metre horizontally from
control unit in a well ventilated area to avoid corrosive damage.
Placement of EQ Unit
Connection of Lines
Product is designed to run with 2 PARTS WATER, 1 PART ACID (2.1 RATIO) should always be
followed as the machines dosing rate is formulated around the diluted solution. Using neat acid
can lead to overdosing the pH level.

Before installing the unit in position on the wall or post, the length of the PVC tubing provided should be measured
and taken into consideration. Ensure the controller and cell are close enough for the power supply lead to reach the
cell and sufficient PVC tube exists to connect acid container and cell. To avoid loss of water from the system, close
all stop valves before cutting any lines.
Thread the clear PVC tube through a hole in the cap or shoulder of the chemical container and fit the non-return or
check valve and the weight. Ensure that the non-return valve is fitted correctly. Drop the weight, with the non-
return valve into the bottom of the container.
The clear PVC tube should snuggly fit in the hole in the cap or shoulder of the chemical container. A small 2mm
breather hole should be made in the cap or shoulder to allow air to fill the void created by the acid pumped into the
pool.
Connect the other end of the PVC tube to the inlet of the acid pump on the front of the controller.
Connect the remaining hose to the outlet of the acid pump on the underside of the controller. The remaining end
of the PVC hose should be pushed through the cable gland in the 50mm PVC mixing cell fitting so that it passes
through the cable gland by 25mm to 30mm.
Locate the injection chamber (diagram below) in a horizontal position after the Chlorinator cell on the return to pool
side.
TIP: Soaking the ends of the PVC tubing in hot water or gently heating with a lighter makes it easier to push onto
the barb. When installing acid container in a filter enclosure, which has no ventilation, it is recommended that the
hole in the cap of the container is cut or drilled to fit tightly around the tubing, so that fumes from the acid will not
corrode the equipment. It will be necessary to drill a second hole in the cap fitted tightly with a length of tubing
which should then be vented outside the filter enclosure. This procedure is recommended only where the filter
enclosure has no ventilation and is to protect the equipment.
•NEVER MIX CHEMICALS
•CHEMICALS MUST BE STORED IN ACCORDANCE WITH RELEVANT STANDARDS AND DANGEROUS
GOODS CODES. CONSULT YOUR AUTHORISED BUILDER OR POOL SHOP TECHNICIAN FOR ADVICE.
•WHEN HANDLING ACID, SAFETY GLOVES AND GOGGLES SHOULD ALWAYS BE USED
•FOR BEST RESULTS, USE A RATIO OF 2 : 1 ACID IS RECOMMENDED

3.4 Setting Timers
Your Viron chlorinator has 4 timers per day enabling you to set different periods in which your filtration pump, pH control
and chlorine production will operate. Control of Lighting is also possible within these timers if Lighting has been Enabled in
the INSTALL menu. Timers are set by entering a start time, and a RUN time for how long you want to operate. To set
timers, do the following:
a. Press the TIMER button.
b. Press HOUR button to set the hour for the timer selected and use the Up/Down arrows to change the Start time.
c. Press MIN button to select the minutes for the timer selected and use the Up/Down arrows to change the Start
time. Press the NEXT button to select the RUN time and set as required. Note: The RUN time represents the
number of hours you want the unit to operate for. If a variable speed pump is enabled, you can then set the pump
speed for this timer. If SLX Lighting has been enabled you can set the Lights to be in OFF or AUTO mode in this
timer. NB you can set the pump to be turned off in a timer if you only require the lights to be on.
d. When finished, press the NEXT button a number of times to scroll through the other times until you return to
normal display. This saves your new settings.
e. Select Auto Sanitising by pressing the POOL mode button. The POOL mode button has three settings, manually
ON which turns on system indefinitely, manually OFF which turns system off indefinitely, and AUTO mode which
sets the controller on timer clock mode. In AUTO mode the LCD screen will display the date and pool sanitiser or
light message.
f. After setting up lighting timers as above, to enable the lighting timers to run, you need to either use the Connect
LITE remote control, or the LIGHT button on the chlorinator to set the Lights to AUTO
See also section 3.2 Installing and using Bluetooth
3.5 Timer Recommendations
AstralPool recommend that you use two timers, one for the morning and one for the evening and typically for periods of 2-5
hours for each for Pool Sanitising. Another timer can be used for Lighting with the pump off (or on) if desired. Generally,
you should operate your pool pump for 8 hours a day in total to achieve sufficient chlorine production and circulate the pool
water including skimming which will reduce debris settling in the pool and ongoing maintenance. Your Viron Series
chlorinator is most effective if running in the early morning or evening when it is cooler (strong sunlight consumes more
chlorine). As a default, the control is set to come on at 08:00 hours and 16:00 hours both for periods of 4 hours.

4.0 Calibration of pH Sensor/Probe:
From time to time, the pH sensor will require cleaning and calibration. Typically, calibration should take place one every 6
to 12 months.
To Calibrate, Press MAINT and next until CAL appears on the LCD. Select CAL to commence the process.
CAL
The pH probes/sensor has been factory calibrated. However, it is a good practice to check the adjustment for the probe
periodically (every 6 months or earlier if required). The probe should be cleaned first (refer under Maintenance page for
cleaning) and allowed to settle down for about 4-5 minutes before adjusting/calibrating. The most accurate way to
calibrate is to put the probe in a calibration solution. Calibration solution is available via AstralPool as a spare part.
When the controller is in Manual Off mode, remove the pH probe from the pipeline (shut off the filter pump and close any
isolation valves to avoid water spill), clean the probe (see under Maintenance) and place it in a 7.5 pH Easy Cal Solution
(available from AstralPool). Press MAINT and then next until CAL is displayed. The unit will ask CHANGE PH

5.1 Adjusting Chlorine Output
Press the SET button to change the chlorine output and the pH of your Pool
Press YES to change the output
Use the up and down buttons to change the Set Point between 0 and 8. 0 chlorine output should only be used when there
is no salt in the water. In summer, the chlorine should be set between 6 and 8 and you should regularly check your chlorine
level in your swimming pool to determine if the output should be increased or decreased. Rely on your pool professional for
advice on the recommended chlorine level in your pool.
As a guide the free chlorine level should be between 1.0 ppm and 3.0 ppm.
5.2 Adjusting pH Set Point
Continue through the SET menu to change the pH balance of your pool.
As a guide the pH in your pool should be set between 7.4and 7.8. This will be determined by the type of pool you have,
(Concrete, Fibreglass, Vinyl Liner) and you should rely on your pool builder or pool professional to recommend the correct
pH Set Point. Use the up and down arrows to set your pH value.
5.3 Acid dosing without sensors.
Your basic Viron e-Quilibrium is supplied without any pH or Chlorine sensors. (These sensors must be ordered separately).
In the “as supplied” format, you can determine the dosing rate of the acid by selecting 1 to 10 in the pH set screen. The
unit will also intelligently adjust the dosing level according to the chlorine production (the higher the chlorine production,
the faster the pH change and the more acid required). However, you MUST check your pH balance in the pool each day for
the first week of operation and adjust the pH setting on your chlorinator until it settles at the desired pH level. Once the
desired pH level is achieved, continue to manually test your pH every week and adjust the pH setting as required.
Installation of the acid dosing tube –to be installed after the chlorinator cell on the return to the pool pipe.
Once the pH value is set your LCD screen will return to the operating information screen which will cycle through the
current status of the chlorinator and the chlorine output setting (between 0 and 8).

5.4 Installation of the pH sensor
The optional pH sensor eliminates the need to regularly test your pH balance of your pool and spa. The sensor will require
checking and recalibrating approximately once every 6 months.
When installed and connected the Viron e-Quilibrium will automatically detect the pH sensor and the factory pH setpoint is
7.6. You can adjust your ideal pH setting in the “settings” menu.
The pH sensor is supplied with a sensor chamber that is connected into 50mm PVC pipe work using 50mm union tails and
lock nuts. Locate the sensor chamber (diagram below) in a vertical, where possible after the filter but before chlorinators
Cell. Glue in 50mm PVC pipe into union tails. Alternatively, locate the sensor chamber in a vertical position after the filter
and before the chlorinator cell. Remove rubber boot from pH sensor and screw into the sensor chamber port as shown.
The remaining ports in the sensor chamber are blanked off using the caps and gaskets supplied as per the assembly
diagram below.

Inst464 –Viron e-Quilibirum Series Chlorinator Instructions V07-20
17
5.5 Installation of the Chlorine Sensor
If you have chosen to have the pH sensor installed, you can now choose to have the chlorine sensor installed. The chlorine
sensor takes away the need to test the chlorine level in your pool and allows the Viron e-Quilibrium to automatically control
the chlorine and pH levels of your pool and spa water. This option is highly recommended for pool and spa combinations,
spa pools and indoor pools and spas.
The chlorine sensor is provided with a 3 metre RJ12 cable for connection to a Viron variable speed energy efficient pump.
However, the chlorine sensor is simply screwed into the pH sensing chamber and connected to the bottom of the Viron e-
Quilibrium controller. Once connected, the e-Quilibirum will automatically detect the sensor and the factory pre-set
chlorine level of 600 mv will operate.
Locate the Sensing Chamber as per section 5.4 before the Chlorinator Cell. The sensor chamber must have the acid
dosing point installed away from the chlorine and pH sensors. Therefore install the acid dosing point after the chlorinator
cell and the chlorine and pH sensors before the chlorinator cell.
Assembly of the Chlorine Sensor. Remove rubber boot from sensor and screw into the sensor chamber which is glued
into pipework either before filter or between filter and Chlorinator cell.
The Chlorine Sensor uses Oxidisation Reduction Potential readings to determine the chlorine level in your pool or spa
water.
ORP is the most reliable and safest way to determine the level of the sanitiser in your water but is affected by other factors
influencing the efficiency of the chlorine. Water pH, the use of sunscreens (cyanuric acid), Hardness and other items can all
influence the reading of the ORP.
The Viron e-Quilibrium will adjust the production of chlorine to meet the ORP which MAY mean the chlorine level, when
measured in simple PPM (parts per million) levels, may change from time to time. This is normal and no cause for concern.
An example of higher chlorine readings when measured in ppm is if the acid runs out and is not replaced. In this case, the
pH will start to increase and the effectiveness of the chlorine will reduce. As the chlorine effectiveness reduces the ORP
measurement declines and the Viron e-Quilibrium will increase the power to the electrode cell to produce more chlorine.
Once the pH level is corrected the Viron e-Quilibrium will reduce or turn off the power to the electrode cell as the ORP
reading will rise.
When the pH and chlorine sensors are connected, the Viron e-Quilibrium LCD screen will display the additional following
messages:
Chlorine Level –(chlorine low, chlorine OK, chlorine high)
Cell was operating at (percentage of maximum output, or “off”)
pH set point (factory preset at 7.6)
pH actual (will read close to set point providing acid container has acid available to be dosed)
For some installations, such as commercial pools it may be beneficial to display the actual ORP reading instead of “Chlorine
OK, Chlorine High or Chlorine Low”. Generally, this is not recommended for residential applications.
Within the INSTALL MENU the following screen is displayed:

Inst464 –Viron e-Quilibirum Series Chlorinator Instructions V07-20
18
The default value is No, so that during operation the screen will only display “Chlorine OK, Chlorine High or Chlorine
Low”. Use the arrows up or down to change the default to “YES” and the screen will then display actual ORP levels.
ORP readings will vary when the filter pump is off and will also vary if Cyanuric Acid is present in the
water. Daylight hours will show a reduced ORP while night time will allow the Cyanuric Acid to detach
from the chlorine molecule which will increase the ORP reading. ORP readings should only be recognised
while the pump is operating and during daylight hours.
6.0 General Operation/Pool Chemistry
6.1 Setting the Right Chlorine Output and Filtration Time
Your e-Q chlorinator must be run every day to ensure that your pool is correctly sanitised. As the sun dissipates chlorine,
running times are higher in the summer compared to the winter. AstralPool recommend that you initially run your
chlorinator at maximum output on level 8.
Summer
You should set your Chlorinator to operate for 8 to 10 hours per day. Ideally, run it for 4-5 hours in the morning (say 8-
12pm) and 4-5 hours in the evening (say 6.00-11pm).
In extremely hot weather it may be necessary to extend the running time if you find that the free chlorine level is too low.
Winter
You should set your Chlorinator to operate for 6 to 8 hours per day. Again, running it in the morning and evening is
preferable. A lower chlorine output level may be selected.
6.2 Checking Chlorine Level.
Ideally, check your Chlorine level after the morning operating period. The free chlorine residual level should be somewhere
between 1 and 3 parts per million. Increase or decrease the output of the Chlorinator to get the right residual chlorine level.
It may also be necessary to adjust the operating period if you are running at minimum or maximum output.
6.3 Stabiliser
Stabiliser (can be referred to as Sunscreen or Cyanuric acid) AstralPool do not recommend the addition of stabiliser in
a pool controlled with an e-Q chlorinator with chlorine probe fitted. If Dichlor or Trichlor is used to supplement the
chlorine production of the e-Q chlorinator or Cyanuric Acid is added to the pool, the set point of the chlorine (ORP)
should be turned down. Refer to Section 10.1 of this operating manual.
6.4 pH Level
You should keep you pH level between 7.0 and 7.4 for fibreglass pools and 7.2 to 7.8 for other pools.
6.5 Total Alkalinity
The ideal range is between 80 and 120 ppm.
6.6 Salt Level
Salt level should be maintained around 4,000ppm but should never be allowed to fall below 3,000ppm. Although salt is
not consumed by the Chlorinator, salt is lost during backwashing, and when your pool overflows due to rain or splashing.
The correct salt level is important to cell life and the effective operation of your chlorinator.
A typical pool of around 50,000 litres requires 200kg of salt to initially set-up the pool to 4,000ppm.
A low salt level warning is indicated on your e-Q Chlorinator if the salt level drops. If Low Salt is indicated, check again in 24
hours and then if it is still indicated, add two 25kg bags of salt to the shallow end of your pool. Run the filtration system for
approx. 6 hours to help mix the salt in the pool. It can take up to a day for the salt to fully dissolve.
If the low salt light is still on, then you should get your pool water tested. If the Salinity is above 4000ppm then you may
need to have your Chlorinator checked.
Warning:Some people recommend that you put salt directly in the skimmer box. This is a very bad practice as it allows
very high concentrations of salt to be passed through your filtration and other pool equipment.
6.7 Acid Handling
Hydrochloric Acid should be handled with extreme care. Refer to Material Safety Data Sheets on Hydrochloric Acid. Do not
inhale Acid fumes. Do not spill and handle with extreme care during transport. Use protective gloves and goggles.
In the case of spillage wash down with fresh water immediately. Keep out of reach of children.

6.8 Acid Pump squeeze tube:
Acid pump squeeze tube must be lubricated every 6 months or more often in commercial applications. Use only the
recommended lubricant RC Tube Lube available from AstralPool or any other compatible silicone lubricant, otherwise
damage to the tube is possible.
Depending upon usage, the squeeze tube may need replacement after 12months on a domestic installation, and earlier on a
commercial installation. Before replacing the tube make sure that any stop valves in the filter system are closed. Otherwise
water loss may occur.
(To replace the tube, remove controller drawer, remove retaining screws from the pump head and pull the tube free.
Disconnect the squeeze tube from the barbs and reconnect the new squeeze tube after lubricating the same, making sure
that the new tube is correctly connected to the PVC tubing as per instructions. Reposition the squeeze tube in the unit as
before, replace the pump head and retaining screws.) DO NOT OVERTIGHTEN THE RETAINING SCREWS.
6.9 Sensors:
The sensors are sensitive instruments. To maintain their accuracy they should be cleaned periodically by household
detergent abrasive like Jif. Jif is the preferred option. The Chlorine Sensor tip can be contaminated (generally observed by a
copper or brownish coating –this should always look shiny gold) which will give a false reading to the Controller causing no
dosing/over dosing of chlorine. As the pH sensor tip is made of glass, please take care, for even a hairline crack can cause
the sensor to read incorrectly causing malfunction.
After cleaning the sensors, wash with water, allow 5-10min. to settle and check calibration or re-calibrate if necessary.
Note, the chlorine sensor may take 30 to 45 minutes to settle and provide the correct reading.
7.0 Ai Mode –complete automatic control of your Pool & Spa
Ai Mode is a unique Patent Applied for system that controls the filtration and chlorine levels in your pool with three primary
objectives:
Completely turnover your pool water every day so that the organic material which looks unsightly and which feeds algae
and bacteria is removed from your pool.
Ensures the correct sanitizer level is achieved to destroy any pathogens, algae and bacteria in the water.
Minimizes the cost of operating your pool and spa.
7.1 Ai Equipment requirements
For your Viron e-Quilibrium to operate in Ai Mode you will need the following equipment:
A Viron e-Quilibrium
pH sensor
chlorine sensor
RJ12 communications cable
Viron eVo variable speed pump
7.2 Ai Mode Connection
Connect your Viron eVo pump to the Viron e-Quilibrium with the RJ12 communications cable and plug the 3 pin plug into
the bottom.
7.3 Ai Mode set up
In the Viron e-Quilibrium “Set Up” screen enter “INSTALL” menu and enable the following:
3 speed pump enabled the volume of your pool and spa in litres (if no spa is installed, leave this at factory pre-set level)
select Ai Mode
Select the size Viron Pump you have installed (1.0 hp for P320/XT320 and 2.0 hp for P600/XT520)
Select the speed of the pump when you have the system manually on –we recommend speed 1 or high speed.
Select “Continue” set up when asked.
the number of complete water turnovers required each day, (suggest factory preset of 1.5 times is adequate)
When asked “Reset to Factory Defaults?” select no.
Finally, exit the “Install Menu” and change the timer period to operate for as long as possible (suggestion of 16 hours –from
8 am to 10 pm)

7.4 Viron eVo Pump speed selection:
•Enable System mode in the Viron Pump menu –refer to Viron Pump Instructions
•Set Pump speeds as follows: Once the RJ12 Cable has connected the pump and eQ Chlorinator, change the
chlorinator mode to “Manual On” to enable adjustment of the Pump Speeds. Note, once the pump is turned Manual
On, it will go into Priming Mode for 5 minutes before the speeds can be changed. Alternatively, set up the pump
speeds before the RJ12 connector is plugged into the chlorinator. Once the pumps speeds have been set up, ensure
the SYS (system) mode is enabled in the Viron Pump Menu.
•In Ai Mode, the high speed should be set at near maximum speed of the pump.
•Medium speed should be set at a speed where the chlorinator electrode cell fills with water during operation and the
skimmer box weir door creates some surface tension on nearby water to skim properly. Usually, this speed will be
between 1200 and 1600 RPM.
•Low speed should be selected at 600 RPM. This speed will be referred to as sampling speed. Ensure water is flowing
through the chlorinator cell at this speed.
7.5 Operation in Ai Mode.
When Ai Mode is selected the Viron e-Quilibrium will operate in the following manner:
•The pump and electrode cell will start at the first time period. After the initial 5 minute priming period, the pump
will revert to filter speed (medium speed), the Viron e-Quilibrium will test pH and chlorine levels and both adjust the
chlorine production and dose acid to achieve the desired levels.
•The Viron e-Quilibrium will ensure the pump operates until its primary two objectives are achieved: (1) the Water is
turned over 1.5 times (on a 50,000 litre pool, the pump will move 75,000 litres of water to ensure all of the water is
filtered) and (2) the chlorine level is achieved. In the winter, this may be only 4 to 6 hours of operation. In the
summer, when the pool is subject to high UV and heavy bather load it may be 12 hours as the chlorine level is
constantly under demand.
•When both objectives are achieved, the Viron e-Quilibrium will turn the pump down to Sampling Speed (approx.600
RPM) which is almost inaudible and costs less than 0.5 cents per hour. During sampling speed the Viron e-Quilibrium
simply tests for chlorine levels. If the family all jump in the pool later at night and the chlorine is dissipated, the Viron
e-Quilibrium will turn the pump back to filter speed (medium) and turn the electrode on to produce more chlorine.
Your family is protected even when swimming later at night as the system is filtering and sanitising the pool or spa
water automatically.
•Finally, if the correct chlorine level is NOT achieved when the system shuts down at the end of the day on time clock,
it will start on maximum output and maximum pump speed the following morning until the chlorine level is achieved.
Once the chlorine level is achieved, the pump will revert back to the gentle filtration speed until the required number
of water turns and chlorine levels are maintained.
•In Ai Mode you can select four timer periods. Each timer period can have a specific pump speed selected (high or
medium) or allow the Chlorinator to select the appropriate pump speed. Normally you will only select a specific
pump speed when you wish to operate a cleaner or water feature at a specific time every day. Low speed cannot
be selected in Ai Mode as low speed becomes the default “sampling speed” to allow the unit to continue to monitor
chemical levels while the Viron Pump is operating at a very low output.
