21.0 Priming the pump / manual dosing

‘Pump Ovrde’ allows you to ﬁ ll the inlet and outlet tubes with dosing solution before

ﬁ rst use (removing any air in the tubes), and to manually dose the tank if required.

Always ensure the inlet dosing tube reaches to the bottom of the pH stock solution

container. Ensure the outlet dosing tube is above the highest water line so that pH

stock solution drips into the tank/reservoir.

NOTE: If priming the pump, temporarily move the outlet dosing tube so it runs into the

pH stock solution container (if not already ﬁ xed in place). This will avoid adding pH stock

solution to your tank/reservoir unintentionally.

Press ‘menu’.

Press ‘’ to ﬁ nd ‘Pump Ovrde’. Press ‘enter’ to select.

Press ‘’ to manually operate the pump. Release

the button to stop the pump when you see the stock

solution begins to drip from the outlet dosing tube

into the tank. Press ‘menu’ to exit.

If the outlet dosing tube was temporarily moved in step 1,

place it back, so pH solution will drip into the tank/reservoir.

CHANGING STOCK SOLUTION: If you are changing from pH Up to pH Down, or vice versa, you

MUST ﬂ ush the dosing tube with water FIRST to avoid a chemical reaction in the tube.

22.0 Set the mode

Use ‘mode’ to select the pH controller connect function. ‘Monitor’ mode shows the

current solution pH reading. It is the factory default setting. ‘Control’ mode allows the

controller to dose pH stock solution to the set values. Dosing will NOT occur when:

• The pH controller connect is in ‘monitor’ mode

• The pH controller connect is in an alarm state

• If the pH controller connect senses dosing is not having an effect on the system

(after 15 dose cycles)

• The solution temperature is above 50 °C / 122 °F, or below 0 °C / 32 °F

To set ‘monitor’ mode:

Press ‘menu’.

Press ‘’ to select ‘Mode’. Press ‘enter’.

Press ‘’ or ‘’ to select ‘monitor’, then press

‘enter’ to save the mode. Press ‘menu’ to exit.

To set ‘control’ mode:

Press ‘menu’.

Press ‘’ to select ‘Mode’. Press ‘enter’.

Press ‘’ or ‘’ to select ‘control’, then press

‘enter’ to save the mode. Press ‘menu’ to exit.

The display will show a countdown before the pump

can start. This is the ‘Pump start delay’, which is set

to these times: 15Sec when exiting the menu with

control mode enabled; 60Sec if power off/on occurs.
