4. START-UP AND ADJUSTMENTS
pH adjustment does not start up until 5 minutes after the equipment has been switched
on.
A proportional control automatically adjusts the pH without the need for controller
adjustments. The pump will start up every minute and with a variable operation time of
between 0 and 60 seconds.
4.5.4 Priming the Pump.
Once the acid pump has been installed, it should be primed to eliminate the installation air.
Go to the "pH" menu and select "Manual". Keeping the "OK" button pressed, the pump will be
running. Keep the pump running with the "OK" button until the liquid has passed throughout
the tube until injection.
4.5.5 Automatic Shut-down and Error Message.
If the acid pump shuts down and the message "pH ERROR" appears, the pump has been op-
erating too long without the pH value lowering to the required level. The causes could be:
• There is no acid.
• Problem in the pump or in the acid duct.
• The probe or probe cable are damaged.
NOTE: To cancel the error alarm, press the "OK" button
4.6 pH Menu (predictive algorithm)
This menu will show instead on the Posi-Chlor pH units, for probe-less control of pool pH.
4.6.1 Acid
You can choose between sulphuric and muriatic (hydrochloric acid). Muriatic or Hydrochlo-
ric acid is the default for Australian pools.
4.6.2 Concentration
This is the concentration of acid in the solution. It will be on the label of the acid container. If
you further dilute the acid, this needs to be taken into account also. For example, if diluting
to a ration of 3 to 1 and the acid container is 32%, after diluting it will be 1/(3+1) = 1/4 x 32% =
8%
