Sensor Care; Finishing And Testing The Installation - Pentair AK110 Installation And User Manual

Contamination of the sensing elements often results in slow response and inaccurate readings . Clean the elements by
the following procedures:
pH and ORP Sensors
1 . Wash electrode tip in a liquid detergent and water . Carefully use a soft bristled toothbrush to wash the
electrode tip and white sensing ring .
2 . Rinse after cleaning . To install, place in flow cell according to the diagram and hand tighten .
3 . Make sure the O-ring is installed on sensor .
4 . If the cable is longer than needed, it should be coiled neatly and attached under the cabinet .
pH Sensors Only
5 . Attempt to clean the sensor with liquid detergent first .
6 . If this is not successful, swirl the tip of the sensor in a 5 parts water and 1 part muriatic acid solution
for 10 - 20 seconds .
7 . Rinse again and reinstall .
Do not rub hard the glass element in the sensor or use sand paper or
Sensors contain external and internal glass elements. Do not drop or otherwise
subject the sensor to vibration, physical impact, or freezing conditions.
ANY TYPE OF BREAKAGE IS NOT COVERED UNDER WARRANTY.
Once the Controller system has been installed with applicable sensors and expansion modules the following steps are
required for final system finishing and testing .
1 . After all wire connections are complete close the panel and tighten the enclosure .
2 . Plug in the Controller and turn on the main breaker . Switch the ON/Off switch to ON .
Up is ON and down is OFF .
3 . Verify that the display is active and displays various introduction/initialization screens .
4 . SENSORS: The first screen displays the sensor readings, verify that they are connected properly .
5 . FLOW: Verify that the flow switch indicates on (S1ON) and the green flow LED is on . Close the valve
in the flow cell to stop the flow and verify that the Controller indicates no flow (S1OFF) and the flow
LED is off .
6 . LOADS: Leave the valve closed (S1OFF) for this part of the test so that the relay programs will keep
relays "automatically" off . Press the Right button 1 time to R1 (ph) OFF and press ENTER to "manually"
turn on the load, verify that the correct load turns on and press enter to turn it off .
Press the down arrow to select the next relay and repeat for the other two relays.

Finishing and Testing the Installation

Example: pH is within 0.5. This is to verify that the pH is connected to the pH input and
the ORP is connected to the ORP input.
