Maintaining the pH FUN
ATTENTION:
Disconnect all power connections before beginning maintenance work!
3.1
Maintenance plan
Monthly maintenance:
•
Visually inspect all dosing lines and hoses for leakage
•
Check the filter sieve and clean it if necessary. Repeat this step more often for strong contamination.
•
Check the pH value using a test kit (commercially available), adjust the settings if necessary
Quarterly maintenance:
•
Visually inspect all dosing lines and hoses for leakage's
•
Check the filter sieve and clean it if necessary
•
Check the pH value using a test kit (commercially available), adjust the settings if necessary
•
Calibrate the pH electrode with supplied buffer solution (see Chapter 6 Performing the pH7 calib)
Annual maintenance:
•
Visually inspect all dosing lines and hoses for leakage's
•
Check the filter sieve and clean it if necessary
•
Check the pH value using a test kit (commercially available), adjust the settings if necessary
•
Replace and calibrate the pH electrode with supplied buffer solution (see Chapter 6 Performing the pH7 calib)
•
Replace the hoses of the dosing pumps
3.1.1 Checking the hoses
Check all hoses for damage (e.g. kinks, tears or leakage's), contamination (e.g. leaves, hair, dust or earth) and
deposits (e.g. limescale).
If there is any doubt, always replace the affected lines. This is the only way to ensure a proper operation.
3.1.2 Cleaning the filter
Close the valve of the measurement water extractor and then the valve of the measurement water return. No further
water is now transported through the measurement cell and filter and the float of the flow switch sinks downwards. Now
unscrew the transparent cover of the filter. Use a container to catch any water that runs out.
Remove the filter sieve and clean it carefully. Use clear water to rinse it.
Now reinsert the filter securely in its seat and screw on the cover again. Make sure the connection is tight.
3.1.3 Dosing pump hoses
The hose of the dosing pump must be replaced annually or earlier if worn. Use the original replacement hose only. You
can obtain this at your swimming pool dealer under BAYROL Art. no.: 171 219 Replacement hose set 0.9 l/h
(identifiable by the white hose nozzles).
Like the pH electrode, the hose of the dosing pump is also a wear part and is exempted from the guarantee/warranty.
