Remote surface mounting the AQL-CHEM:
The Probe Cell can be mounted up to 15'
away from the Aqua Rite Pro or the Pro Logic (limited by length of cable). Use the
four mounting holes on the back of the bracket when surfacing mounting. Common
wood screws can be used for most applications.
Plumbing the Probe Cell to the pool plumbing
The Probe Cell requires connection to the pool plumbing using the supplied flex
tubing. Two ports on the Probe Cell, influent and effluent, are connected to the
supply and return sides of the pool plumbing. Refer to diagram below as well as the
following steps:
Use remote

when surface mounting.
Normal Operation
During normal operation, the AQL-CHEM will sense ORP and pH requiring no user
input. The current ORP and pH levels will periodically be shown on the display.
Pushing the "<" or ">" buttons will advance you to this display quickly. For the Pro
Logic, this information can also be found within the Diagnostic Menu.
The desired ORP and pH levels can be changed by restarting the Chemistry Config.
Wizard.
Maintenance
Water Chemistry
Always test water chemistry with a quality manual test kit. The AQL-CHEM provides
instrument grade accuracy which exceeds that of most liquid-standard water testing
kits. Therefore, it may be preferable to calibrate pH using commercially available
reference solutions. Calibrate pH periodically using the pH Calibration Wizard as
described earlier in this manual. It's important to note that changes in pH, cyanuric
acid concentration, total dissolved solids, and use of additional or alternative sanitizers
will all affect the primary sanitizer residual level relative to ORP. Maintain total alkalin-
ity on regular basis to ensure pH stability. To maintain a consistent sanitizer residual
in parts per million (ppm), periodically adjust the ORP level.
Probe Maintenance
The probes must be clean and free from oil, chemical deposits and contamination to
function properly. After saturation in pool or spa water, the probes may need to be
cleaned on a weekly or monthly basis depending on bather load and other pool
specific characteristics. Slow response, increased need to calibrate pH, and inconsis-
tent readings are indications that the probes are in need of cleaning.
To clean the ORP and pH probes, run the Clean Probe Wizard within the Settings
Menu on the Aqua Rite Pro or the Maintenance Menu on the Pro Logic. This Wizard
will walk the user through the probe cleaning process. Answer the questions when
prompted, and follow the instructions for proper cleaning.
To clean the probes without running the Wizard, turn off input power to the Aqua Rite
Pro or Pro Logic. Disconnect the probe connectors from the communication box,
unscrew the probe and carefully remove them from the Probe Cell. Clean the reference
junction (the white ring at the bottom of the probe body) with a soft toothbrush and
regular tooth paste. A household liquid dishwashing detergent may also be used to
remove any oil. Rinse with fresh water, replace teflon tape on threads and reinstall
probes. If properly cleaned probes continue to provide unstable readings or require
excessive calibration, the probes should be replaced.
Probe Storage
Exposure to atmospheric conditions will cause the probe tips to dry out. Store the
probes with the included plastic probe storage caps if removed from the Probe Cell for
more than one hour. If the storage caps have been misplaced, store the probes indi-
vidually in small glass or plastic containers with clean water covering the probe tips.
Store probes in a location that will not be subjected to freezing temperatures.
