5. Operation
5.1 Startup
Do not add chemicals to the feeders until all startup operations are completed. Using a DPD
test kit, manually adjust and balance the water chemistry to acceptable ranges. Automation
should be used to maintain chemical levels, not to balance a pool that is far out of
acceptable ranges. With the controller in the OFF mode, turn the filter pump on and check
for leaks in the system and flow through the flow cell. The flow lamp will be illuminated if the
controller has power, it is connected to the flow switch and there is adequate flow. If a flow
switch is not attached, the flow lamp will be illuminated if there is a jumper in the Flow
Switch Terminal allowing the controller to be used without a flow switch. Using a flow switch
is always recommended.
A properly installed and functioning flow switch will disconnect power to chemical feeders if
there is no water flow in the circulation plumbing. Test flow switch monthly by closing left-
hand valve on Flowcell and confirming that the flow light turns off. Then re-open valve and
confirm that light turns back on.
5.2 pH settings
Press and release the controller MODE button until the pH LED is lighted (refer to the
description of controls). Then select the desired Set Level, Feed Time and High and Low
Alert Levels. Adjust Consecutive Feed Alert Limit if Set Level is not met within preset limit as
indicated by the Digital Display flashing. –See appendix for detail.
Note: Controller can be set to feed acid or base. See Acid/Base pH chemical feed section
in Appendix for Dip switch settings. To verify that acid feed mode is selected adjust the pH
set level below the pH indicated on the display. The feed lamp should come on if the
controller is in acid feed mode. To verify that base mode is selected adjust the pH set level
above the pH indicated on the display. The feed lamp should come on if the controller is in
base feed mode.
5.3 pH Calibration
The pH sensor can drift slightly over time and calibration will offset this drift. Always calibrate
using water from the sample port of the flow cell and use an independent pH test method to
determine pH value of sample, unless using preset buffer solution. Press and release the
controller MODE button until the pH LED is lighted (refer to the description of controls). Then
use pH CALIB button to adjust reading to match known pH value of sample. It may take up
to 24 hours for the sensors to acclimate to the system so recalibrate 24 hours after the first
calibration. The pH sensor calibration should be checked every four to six weeks. If
calibration is required more often then probe may need cleaning or replacement.
