Frequently Asked Questions - Viron V18 ASTRALPOOL

How do I properly install the Viron V18 pump?

Ensure the pump is installed on a stable, level surface, below the water level for self-priming. Use rigid PVC piping with the correct diameter (50 mm). Connect suction and discharge lines securely, and ensure electrical connections comply with local codes.

How do I prime the pump?

Remove the strainer basket cover and fill the pump housing with water until it overflows. Replace the cover tightly, then turn on the pump. If it doesn't prime within a few minutes, check for air leaks in the suction line.

How often should I clean the strainer basket?

Check and clean the strainer basket weekly, or more often if debris is heavy. A clogged basket reduces flow and can damage the pump.

Why is my pump making excessive noise?

Common causes include cavitation (low water level), loose mounting, or debris in the impeller. Check water level, tighten bolts, and inspect the impeller for obstructions.

What type of oil does the motor require?

The motor bearings are sealed and do not require oiling. No regular lubrication is needed, but if the motor becomes noisy, it may need professional service.

How do I winterize the pump?

Drain all water from the pump by removing the drain plugs. Store the pump in a dry, frost-free area. Cover the electrical connections to prevent moisture.

What are common error codes and their meanings?

This model does not have digital error codes. If the pump trips the circuit breaker, check for electrical shorts or overloading. If it runs but no flow, check for blocked impeller or air leaks.

Can the pump be used with a saltwater pool?

Yes, the Viron V18 is compatible with saltwater chlorinated pools. However, ensure the pump materials are resistant to corrosion; regular maintenance is recommended.

How do I replace the mechanical seal?

Disconnect power, remove the motor and volute. Unscrew the impeller and old seal. Install a new seal carefully, ensuring the ceramic and carbon faces are clean. Reassemble in reverse order.

What is the recommended pump speed for maximum efficiency?

The Viron V18 is a single-speed pump. For energy savings, operate it during off-peak hours and use a timer to limit runtime to 8-10 hours daily.

1.0 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 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

2.1 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 Chlorinator cell into line as per drawing below after filter, heater and solar (if installed).
c. Plug filter pump 3 pin plug into underside of Controller.
d. Connect 4 wire cell cable ensuring matching colours.

e. 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.

f. Hang Controller on wall bracket and plug power supply lead into 3 pin 10 amp outlet.

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. 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.

    style C fill:#99ccff,stroke:#333

Use the up and down buttons to change the Set Point between o and 8. o 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. See also section 3.2 Installing and using Bluetooth5.0 General Operation/Pool Chemistry

5.1 Setting the Right Chlorine Output and Filtration Time

Your Viron series 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.

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.

5.2 Stabiliser

Sunlight rapidly dissipates the amount of free chlorine in your pool. Chlorine stabiliser greatly reduces this effect. Without stabiliser, you may need to run your chlorinator and filtration system up to 16 hours per day or longer. Keep the Stabiliser reading between 30 and 60ppm.

5.3 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.

5.4 Total Alkalinity

The ideal range is between 80 and 120 ppm.

5.5 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 Viron 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.

5.6 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.

5.7 CHLORINATOR MAINTENANCE AND TROUBLESHOOTING

If the supply cord is damaged, it must be replaced by Astralpool or its service agent or a similarly qualified person in order to avoid a hazard.

Cell Maintenance

Your Viron Chlorinator has an automatic cleaning feature that under normal conditions, will keep the cell plates clear of deposits of salt and calcium.

Viron Series cells have a positive charge sensor that monitors the flow and salt levels of the water. This sensor is designed to be fail safe. DO NOT ATTEMPT TO ABRASIVELY CLEAN THE FLOW SENSOR, THE FLOW SENSOR IS COATED WITH SPECIAL RARE EARTH MATERIAL AND IF DAMAGED FROM ABRUSIVE CLEANING BY REMOVAL OF THIS COATING WILL RESULT IN CORRUSION TO THE SENSOR PLEASE REFER TO BELOW "CELL CLEANING INSTRUCTIONS" DAMAGE TO THE SURFACE OF THE FLOW SENSOR FROM INCORRECT CLEANING WILL NOT BE COVERED BY WARRANTY

Cell Cleaning Instructions:

• close applicable valves
• disconnect the Chlorinator from the Mains by removing the 3 pin plug
• disconnect the cell wires
• undo the barrel nuts connecting the cell to your filtration system
• turn the cell upside down (inlet and outlet on top) and fill the cell with a mix of 1 part Hydrochloric acid to 10 parts water and leave standing for a few minutes. As an alternative, you may use an approved commercial Cell cleaning solution
• repeat if necessary and then rinse well in clean water
• do not abrasively clean the Flow Sensor to clean, ensure flow sensor surface is not damage. Damage to the surface or removal of the coating from abrasive cleaning of the flow sensor will not be covered by warranty
• re-install the cell ensuring o-rings are correctly located and barrel nuts are tightened to prevent leaks
• re-connect cell wires with wing nuts supplied making sure the blue wire is connected to the blue terminal. Incorrect connection may damage your chlorinator control. Tighten wing-nuts to ensure the electrical connection is sound
• Return all valves to their normal positions, re connect power to the Chlorinator and turn on at power point.

WARNING: Follow safety instructions provided with the Hydrochloric acid or cleaning solution. When handling Hydrochloric Acid, the use of eye protection, mask and gloves are highly recommended. Extreme caution should be taken whenever handling Hydrochloric Acid or Cell Cleaning Solution.

6.0 Swimming Pool Applications and the use of Cyanuric Acid

USE OF A SUN SCREEN CHEMICAL (CYANURIC ACID) FOR OUTDOOR POOLS IS RECOMMENDED. CHECK WITH YOUR LOCAL POOL SHOP AND USE THE CORRECT DOSAGE. ENSURE YOUR POOL WATER IS WELL BALANCED WITH THE CORRECT pH, TDS, TA AND STABILISER LEVELS AND FREE FROM PHOSPHATES.

Maintenance of your Chlorinator

Maintenance Schedule: Your new product incorporates moving parts and withstands high velocity water with chemicals in it. Some of these parts will wear in the normal course of use and require regular checks and maintenance. Performing these checks and maintenance will identify parts that have worn and require repair/replacement before further serious damage is sustained. A small amount of regular care and attention to your pool equipment will help ensure long life and trouble free performance.

To protect against extremes of temperature, your unit is vented to allow expensive electronics to cool. Ants and some insects are often attracted to the warmer, dry environment inside the enclosure. We recommend that, with power turned off, you spray a surface insecticide on the surfaces surrounding the control to prevent ant and insect ingress. Repeat every three months or as necessary.

Timing	Maintenance Check	Service action (if required)
Fortnightly	Check cell for calcium build up	Soak cell in mixture of 10 parts water to 1 part acid. Use a soft brush only if required
	Check water chemistry	Balance pH in pool and adjust output of unit to ensure satisfactory production of chlorine.
	Check cable connections to cell	Adjust pins by separating if not held firmly in place. Ensure no water contact is occurring with pins
Three Monthly	Check cell connections for leaks	Isolate Pump, turn power off, clean and grease O rings or replace if necessary Spray a surface insecticide on the surfaces around the unit to prevent ant and insect ingress.
Six Monthly	Check chlorine levels and pump operating hoursPrevent insect ingress to controller	Adjust timer and output depending on demand for current season.Turn controller off, use an insect spray and spray onto walls around controller. Do not spay directly into unit.

Important note: Regular maintenance is important to ensure long life and trouble free performance of your pool equipment. If unable to perform the maintenance yourself, contact your local AstralPool office who will arrange a trained service technician to perform the maintenance for you.
