•
Switch the device off (button), then press
M
to begin calibration
•
Wait for the read out to stabilise, and press
M
to adjust the sensor to pH = 7
•
Remove the pH sensor, rinse it, shake it to remove any drops (do not wipe it), then immerse it in a
pH 4
buffer solution.
•
Wait for the read out to stabilise, and press
M
to adjust the sensor to pH = 4
•
The message
DONE
is displayed, confirming that calibration is complete.
10.3
Calibrating the Redox sensor (EES Pro only)
This operation requires both the pH and Redox sensors.
!
Check first that the sensors are clean, then rrinse with clear water, this will ensure that the calibration
process is more accurate.
10.3.1 Frequency of calibration
The redox sensor should be calibrated:
•
The first time the device is put into operation,
•
upon reopening the pool after winterizing,
•
Approximately every 6 weeks during the pool season.
10.3.2 Materials required
Calibration requires the following materials:
•
Glass of tap water, or a tap nearby
•
Redox buffer solution
10.3.3 Procedure:
•
Start the device leaving the filtration pump off (S
T-BY mode
), close the valves of the by-pass loop on which
the tee housing the sensors is mounted. (place a bucket under the tee to collect any water)
•
Remove
the pH and the Redox sensor
, rinse them and shake them to remove any drops (do not wipe),
then immerse them in the Redox buffer solution and move them gently in the solution.
•
Wait approximately 1 minute
•
Switch the device off (
button), the LCD display will show "OFF".
•
Press
M
to enter calibration mode.
•
When ORP is displayed, press the
button.
•
Press the button
M
again to begin calibration.
•
Wait for the read out to stabilise, then, using the arrow keys, adjust this value to that indicated on the redox
buffer solution bottle.
•
Press the button
M
again to confirm this setting.
•
The message
DONE
is displayed, confirming that calibration is complete.
10.4
Replacing the internal tube of the aicd dosing pump
It is recommended to replace the check valve and internal tube of the dosing acid pump before starting a
new bathing season and/or every six months during the season. Please contact your local dealer to obtain
a new tube. The internal tube requires replacing when ACID PIPE message is visible
!
WARNING As there is a high risk of acid splashing or leaking out, safety glasses, gloves and protective
clothing should be worn.
