7.8 Manual Cell Cleaning
Create a mild acid solution, of 1 part hydrochloric acid to 5 parts water in a bucket of water. Always add Acid to
the water.
To clean cell – turn power to chlorinator off to prevent pump operating. Close isolation valves if chlorinator cell is
installed below water level. Supply leads, sensor lead and PVC tube may require removal from the Cell.
Unscrew the lock ring in an anti clockwise direction. Remove electrode from assembly from the cell housing.
Soak in Acid solution for 30 minutes and use a soft brush to remove calcium deposits and debris.
Reassemble Cell housing and reconnect power lead and PVC tube. Turn power onto chlorinator.
8.0 MAINTENANCE OF PH SENSING AND DOSING
8.1 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 draw, 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.
8.2 The probes/sensors, which are sensitive instruments. To maintain their accuracy they should be cleaned
periodically by household detergent abrasive like Jiff. Jiff is the preferred option. The ORP probe tip can be
contaminated (generally observed by a copper or brownish coating – this should always look shiny silver) which
will give a false reading to the Controller causing no dosing/over dosing of chemical. As the pH sensor tip is made
of glass, please take care, for even a hair line crack can cause the sensor to read incorrectly causing malfunction.
After cleaning the sensors/probes, wash with water, allow 5-10min. to settle and check calibration or re-calibrate if
necessary.
8.3 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 STABILSER LEVELS AND FREE
FROM PHOSPHATES.
