UP Precision pH Controller Setup Instructions

All components of the UP Precision pH Controller
Step 1) Familiarise yourself with the parts:
A: Mains plug.
B: Power Box with plug for Solenoid.
C: pH 4 and pH 7 Calibration Solutions.
D: Control Unit.
E Control Unit and Electrode mounting brackets.
F: pH Electrode / Probe.


Connecing the Control box and Power box
Step 2) Connect the Control Unit to the Power Box using the cable supplied.


Connecting the electrode to the ph controller
Step 3) Connect the pH Electrode to the control unit.


Plugging the ph controller to the mains supply
Step 4) Plug the pH Controller into mains socket and switch on.


Selecting for CO2 or Calcium reactor use
Step 5) If using 'HI-A' the controller will switch on the CO2 when the pH climbs ~0.05 above the target pH. It will remain switched on until the pH drops ~0.05 below the target pH.

If using 'LO-A' the controller will switch on when the pH drops ~0.05 below the target pH. It will remain switched on until the pH climbs ~0.05 above the target pH.


Setting the target pH of the controller
Step 6) Slide the switch to "SET" and adjust the target pH you wish to maintain in your aquarium.

The majority of aquatic plants and tropical fish prefer a pH of 6.8. But please check for your specific fish / plants whether they have a certain requirements. Please remember, the health of your fish is always more important than that of your plants.


Calibrating the pH controller to pH 4
Step 7) Remove the electrode from its storage bottle and place the end of the electrode in the pH 4 calibration solution. Leave for 5 minutes for the electrode reading to stabilise.


Set the controller to pH 4
Step 8) Slide the switch to "PH" and adjust the "PH4" adjuster until the display reads "4.00". The controller is now calibrated for pH 4.


Setting the pH controller to pH 7
Step 9) Now place the electrode in the pH 7 calibration solution. Leave for 5 minutes for the electrode reading to stabilise.


Setting to pH 7 on the controller unit
Step 10) Keep the switch set to"PH" and adjust the "PH7" adjuster until the display reads "7.00". The controller is now calibrated for pH 7.


Deply the pH electrode in the aquarium
Step 11) Leave the control unit set to "PH" and remove the electrode from the calibration solution. Using the mounting bracket, position the electrode in the aquarium ensuring the cap is above the water level.


Attach the control unit to the aquarium
Step 12) If desired, the control unit can be mounted on the side of the aquarium using the bracket.


Plug the solenoid into the power box
Step 13) Plug the solenoid for your regulator into the controller's output plug.


Installation of the UP Precision pH Controller is complete.
Step 14) The controller will now display the current pH of the water where the electrode has been deployed, and will activate the output plug to maintain the target/set pH.

The controller will switch on the solenoid / CO2 when the pH climbs ~0.1 above the target pH. It will remain switched on until the pH drops ~0.1 below the target pH.

You may wish to check the pH4 and pH7 calibration every couple of months to ensure accurate operation.

Clean the electrode every 2-3 weeks using a soft brush. Do not use finger, cloth, alcohol or any other cleaning products.

Using a Drop Checker

If you are using a drop checker, monitor it until it turns a light green colour, which represents the optimal level of CO2 that's needed for your aquarium. Referring to the pH controller, you can note the pH of the aquarium, and then set that as the target pH. The pH controller will then maintain the level of CO2 that your aquarium needs for the drop checker to turn light green, ensuring you maintain the optimal level of CO2 in your aquarium.
