2.0 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. Automation should be used to maintain chemical levels, not to balance a pool/spa that is out of acceptable chemical ranges.
3.0 Description and Specifications 3.1 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.
3.2 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.
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. • When Flow light is on and Auto light is off, levels can be set. Set level button: Pressing the set level button once will display the current set level. To change the set level, press the set level button until the desired level is reached.
4.3 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 4.3.1 Fuses Fuses protect the controller from defective feeders. They are located inside the enclosure. The fuse holders are shipped with 5 Amp fuses. 4.3.
5.0 Operation 5.1 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.
B. Simultaneously depress and hold ‘Set Level’ and ‘Re-Set’ buttons. While they are depressed, press the Mode button. The display will read ‘LD’ and then turn On. C. Release the buttons. D. The controller is now in test mode. Test mode shortens minutes to seconds. E. Turn the controller Off again to exit test mode. F. Turn the controller On to return to operating mode. The last two steps are extremely important since this puts the controller back in operating mode.

8.0 Appendix 8.1 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.
