Caution: Be certain to verify that the proper relay has been used and configured
for pH.
•
Verify proper relay operation by using the pH Reduction CTRL set to "Forced on"
•
Observe that the relay immediately turns on and applies power to the CO2 feed
solenoid or acid dispense pump
•
Once this is verified, set pH Reduction CTRL back to AUTO
As a last check for proper configuration, push the corresponding output button for
the pH Dispensing device. The device SHOULD NOT TURN ON. If it does, go back
through the configuration to determine the problem.

Operation

Before operating the AQL-CHEM, test and adjust the pool water chemistry to the
recommended levels in the Aqua Rite Pro or Pro Logic Operation manuals. This is an
important step and is crucial to the successful operation of the AQL-CHEM. Adjust
salt to recommended levels if using an Aqua Rite Pro or a Pro Logic with an AQL-CL
chlorination kit.
Controlling ORP with the Aqua Rite Pro or Pro Logic
Follow these steps to set the desired ORP level:
1. IMPORTANT: Balance the pool water to the ideal levels shown in the Aqua Rite
Pro or Pro Logic manuals, including pH, total alkalinity, cyanuric acid, hardness
and salt level.
2. Adjust the chlorine to the ideal level as well; e.g. 1-3 ppm free chlorine. This
chlorine level is what we want to maintain.
3. After allowing the system to run for 30-60 minutes, observe what the Sense and
Dispense system reports as the pool water ORP level.
4. Set the ORP setpoint setting to this reported ORP level.
5. Monitor the free chlorine and ORP everyday for 1 week. If adjustments to the ORP
setpoint are needed, make adjustments in increments of 10 or 20 mV units—
LARGE ADJUSTMENTS OF THE ORP SETPOINT SHOULD NOT BE NECES-
SARY IF YOU STARTED WITH A BALANCED POOL THAT HAD THE PROPER
AMOUNT OF FREE CHLORINE.
6. If the system is not stabilizing (or does not seem to be stabilizing) there are 3
things you can do:
a. Clean the probe
b. Rebalance the pool –including the free chlorine level
c. Check for combined chlorine—if high (>0.5ppm), shock treat with chlorine
or non-chlorine shock.

Wiring the probes to the Probe Cell
Both probes must be wired to the communication box within the Probe Cell. The probe
cables use typical BNC connectors that attach to the designated connectors on the
communication box. Refer to the label on the communication box for the appropriate
connections. Push the connectors in and turn clockwise until locked. After connect-
ing, route the wires in a manner where they will not interfere with the door of the Probe
Cell. Save BNC connector protective covers for future use.
Wiring the Probe Cell to the Aqua Rite Pro or Pro Logic
The Probe Cell is supplied with a 15' cable which connects to the circuit board of the
Aqua Rite Pro or Pro Logic. Route the cable through an available knockout and make
the proper connection as shown below. When side mounting the Probe Cell, route
the cable through the access hole at the bottom of the mounting bracket BEFORE
screwing the bracket in place.
