WEIPRO pH Controller Setup Instructions

Step 1) Familiarise yourself with the parts:
A: pH Electrode / Probe.
B: Control Unit.
C: Plug for Solenoid.
D: Mains plug.
E: pH 7 Calibration Solution.

Step 2) Connect the pH Electrode to the control unit.

Step 3) Plug the pH Controller into mains socket and switch on.

Step 4) Slide the switch to "SET" and use the screwdriver provided in the kit to 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 certain requirements. Please remember, the health of your fish is always more important than that of your plants.

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

Step 6) Slide the switch to "PH" and adjust the "CAL PH7" adjuster until the display reads "7.00". The controller is now calibrated.

Step 7) Leave the control unit set to "PH" and remove the electrode from the calibration solution. Position the electrode in the aquarium using the suction clips provided, ensuring the cap is above the water level.

Step 8) Plug the regulator's solenoid into the controller plug.

Step 9) 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 recalibrate the controller 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.
