pH/ORP/Conductivity
1.
Splice in one reducing tee for each sensor (pH, ORP
and Conductivity) with pipe dimensions as required by
existing pool plumbing. Sensors should be located after
the filter and before the heater or electrolytic chlorine
generator. Each sensor requires 1/2 inch NPT female
pipe threads and should be positioned approx. 45°
from vertical.
2.
Sensors are shipped with caps to protect the active
portion of the sensor. Remove the caps and install
the sensors into the plumbing by HAND TIGHTENING
ONLY. (See “
Dislodging air from within the pH
bulb tip
” below.) Keep the sensor caps for long-term
storage or winterizing of the sensors. Sensors should
not be exposed to freezing conditions.
3.
Route sensor wiring into the bottom left side of the
enclosure. Maintaining drip-loops at each sensor and
service loops inside the enclosure.
4.
Connect pH, ORP and Conductivity sensors to the
appropriate connections on the sensor board (P/N
22857). The ORP sensor is identified by a black colored
boot with ORP in white lettering. Insert the connector
into the J2 connector on the sensor board in the
upper right corner. Twist the connector approximately
90° to lock. Insert the pH sensor connector (white
boot with pH in black lettering) into the J1 connector
on the sensor board. Finally, insert the small square
black connector of the Conductivity sensor into the
J7 connector.
5.
Enable installed sensors and disable uninstalled
sensors using the jumpers located on the bottom left-
hand side of the sensor board. Connecting the jumpers
between the two-pin locations enable sensor readings,
and removing the jumper disables the sensors.
6.
Press the four (4) nylon stand-offs into the sensor
board (PN 22857) and position it over the connector
J11, located in the upper left corner of the Poolux
Board (P/N 22890). After ensuring proper alignment
and that the J11 connections slide easily into the
connector, press the four (4) stand-offs into the control
board. Continue pressing until the sensor board snaps
into position.
7.
Continue to the calibration procedure (if required).
The display on the panel will show the actual pH reading in
the body of water. Add any necessary chemicals to insure
that the pH sensor reading remains between 7.2 and 7.8 pH.
Requirement: Use a test kit no less than once a month
to verify pH calibration and optimal ORP readings.
Note: ORP readings are affected by the following factors:
water temperature, total dissolved solids, cyanuric acid
(stabilizer conditioner), and alkalinity.
CALIBRATION PROCEDURE
1.
Ensure the pH sensor is installed and enabled.
2.
Place the pH sensor into a 7.0 pH reference solution
at 75°F and allow the sensor to sit a minimum of
15 minutes.
3.
Connect the J9 CAL jumper to both pins. This jumper
is located on the upper left-hand corner of the
sensor board.
4.
Turn system power on.
5.
Observe the yellow LED calibration status indicator.
This LED is identified as D7, located on the upper
left-hand corner of the sensor board. When the LED
begins to flash, remove the J9 CAL jumper then
wait for the LED to stop flashing. When the LED
stops flashing, turn the system power off.
6.
Reinsert the pH sensor into the sensor tee and verify
the readings with a known pH measurement
technique (i.e., chemical reagents or test strips).
7.
Repeat steps 1-5 as required for calibration.
CARE AND MAINTENANCE OF SENSORS
Unpacking
Remove the sensor from its package and check that it is
undamaged. If damaged, contact the manufacturer for
replacement. Most sensors are rugged in design, but some
are fragile. Care should be taken when unpacking and
handling all electrodes.
Preparations for use
All sensors are shipped with a wetting cap covering the
electrode end. Gently remove the wetting cap from the
electrode by unscrewing the cap from the sensor body, then
slide the cap and o-ring off of the electrode body. Save the
cap for future long-term storage. Some sensors are shipped
with slide-on caps that are simply pulled off.
CALIBRATION AND CARE
INSTALLATION OF SENSORS
pH, ORP and Conductivity sensors are mandatory when a chlorine generator is being used. These reading will allow the
control to generate chlorine, adjust pH, and deliver alerts when chemistry is out of the desired ranges.
