QUICK START REFERENCE Use this section for reference - please read all safety instructions and appropriate manual sections for installation and operation instructions. • Do NOT add chemicals to feeders until all start-up operations are completed. • Manually adjust and balance pool/spa to acceptable levels and verify using DPD test kit prior to start-up.

1.0 Safety Instruction A- WARNING: Do not shut down circulating and control system immediately after using pool, spa or hot tub. Systems must operate until water chemistry is stable. Systems must be restarted before water chemistry is out of NSPI recommended ranges or water chemistry must be manually corrected. B- WARNING: Removing power from circulating pump must also remove power from the controller. Provide a properly located outlet controlled by the circulating pump circuit.
2.0 Description and Specifications 2.1 General Description The controller is a microprocessor-based chemical automation system, which continuously monitors and maintains the ORP level in a swimming pool or spa. The ORP is displayed using sun-bright light emitting diodes. The ORP level is continuously monitored and displayed on the controller’s front panel. The ORP controller has been designed to be user friendly. One MODE button and two SET buttons allow the operator to easily set parameters.
2.2 Specifications Display: Control: Factory default: 0 to 995 mV 400 to 900 mV 650 mV Input Power 120 Volts AC, 50/60 HZ, 3 wire grounded power cord. GFCI source required Output Power 120 Volts AC, 50/60 HZ, 5 amps (fused) Two 3-wire grounded power receptacles Terminal strip for hardwire applications.
• To turn the controller “OFF” press MODE so the AUTO light is off and hold the MODE button for two seconds until the ORP displays read “OFF”. Release the MODE button, the controller turns off and the display goes blank. Note: Turning the controller “OFF” using the MODE button simply turns off the controller functions, but does not turn off the power to the controller. The FLOW lamp is both the power light and a flow indicator when flow switch is used.
3.3 Power access panel Access to terminals is through the back of the enclosure. With the controller removed from wall/panel, remove four screws holding enclosure panel to enclosure body. TERMINAL STRIP FUSE HOLDER FLOW SWITCH TERMINAL FLOW SWITCH JUMPER FLOW SWITCH LEADS 3.3.1 Fuses Fuses protect the controller from defective feeders. They are located inside the enclosure. The fuse holders are shipped with 5 Amp fuses. 3.3.
4.0 Operation 4.1 Startup Do not add chemicals to the feeders until all start-up operations are completed. Using a DPD test kit, manually adjust and balance the pool to acceptable ranges. Automation should be used to maintain chemical levels, not to balance a pool that is 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.
4.5 Reset The controller can be reset at any time to the default factory settings. Follow the steps below: (note: ‘Re-Set’ button is unmarked and located directly to the right of the Feed Time button). A. Press ‘Mode’ button to turn ‘Auto’ light off. B. Hold ‘Mode’ button until ‘OFF’ is displayed. Release ‘Mode’ button. Display should be blank. C. Hold the ‘Set Level’ and ‘Re-Set’ buttons and then the press Mode button (all three buttons held at same time). D. The display will read ‘LD’ and then a number.
* Controllers are designed to maintain set-points. Do not expect Controllers to make major adjustments—major changes should be done manually. * Pump/feeders must be large enough to reach desired set-points in a relatively short time. Automation using controllers may require larger feeder or more concentrated chemicals than system that uses continuous time controlled feeding (i.e. feeders only). 6.0 Warranty and Service6.
7.0 Appendix 7.1 WATER CHEMISTRY RANGES (These ranges are in accordance with suggested NSPI Standards for swimming pools.) pH: 7.4 -7.6 Alkalinity: Approx. 80-120 ppm ** (parts per million) Higher levels may be acceptable in areas where it naturally occurs in the local water supply. Consult a pool professional in your area. Cyanuric Acid: 0-50 ppm. (Maintain at 30 ppm or less for best probe life.)* TDS (Total Dissolved Solids): 300 - 2000 ppm Calcium Hardness: 200-400 ppm Free Chlorine: 1.0 - 3.
