Automatically Dose Acid – the ADJUST AutoDOSE Sub-
MENU
Note: fibreglass and liner pools are unlikely to need adjustment of auto dose
amounts.
This sub-menu allows you to adjust the amount of acid added as an
automatic dose. Adjustment of the DOSE# is in increments of 10.
PressY/UP when Line 2 of the LCD asks "ADJUST Auto DOSE?" to enter
this sub-menu.

Use the Y/UP and/or the N/DOWN buttons to adjust the amount of acid to
be dosed automatically. The value will be used by the algorithm to
determine how much acid and when to add it automatically.
Press ENT to confirm and return to the Home Screen and normal operation.
Priming the Dosing Pump
To prime the acid feed line – go to the +ACID Menu and do a manual feed
of 100mL (or more if necessary due to length of feed tube). Note: the
dosing pump will only start after the filtration system has been running for 2
minutes' "start delay". Once the dosing pump is running, double check the
pump rotor direction and ensure it is correct (otherwise water will be
pumped into the acid drum.)
Adjusting the pH Control for Dilute Acid (Advanced Settings Menu)
If a unit has been installed with the pH Control Dose Pump this setting has likely already
been made by the installer.
To enter the Advanced Settings Menu hold the OFF-button down for approximately 4
seconds and when Advanced appears in the display press ENTer. Use Y/UP or N/DOWN
buttons to scroll through the menu until LCD Line2 shows "ACID Dilution" and press
ENTer. The LCD will show:
"Dilution NO"
"Dilution Y/N?" Press Y/UP for dilute acid use.
There are three possible dilution rates to select from using the Y/UP and N/DOWN buttons:
"Acid approx 10%"
"1 Acid : 2 WATER"
Note that undilute acid is generally 28 – 32%. Note also that dose pump run times are
longer when dilute acid is used.
