1.0 SAFETY: When installing and using this electrical equipment, basic safety precautions should always be followed, including: 1.1 WARNING !: To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times 1.2 WARNING !: Risk of electric shock. Connect only to a grounding type receptacle protected by a ground-fault circuit interrupter (GFCI).

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 pH balance in a swimming pool or spa. The pH is displayed using sun-bright light emitting diodes. The pH level is continuously monitored and displayed on the controller’s front panel. The controller has been designed to be user friendly. One MODE button and three SET buttons allow the operator to easily set parameters.
3.2 Specifications Display: Control: Factory default: pH 6.8 to 8.2 pH 7.0 to 8.0 pH 7.4 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 an optional 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 JUMPER ACID FEED BASE FEED 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.
4.3.3 Acid/Base Feed Selection: The controller has a terminal shipped with a ‘jumper’ used to select acid or base chemical. The jumper can be moved to change type of feed. Factory setting is acid feed. Acid feed mode will feed chemical when the pH reading is above the pH set point. 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.
Low feed rates can cause the feeder to lag or feeding to be extended. A high feed rate can result in too much pH chemical being added. To verify the feed type (acid or base) adjust pH “set” level above the pH indicated on display. The feed lamp should come on if the controller is in acid feed mode. If the controller is in base feed, the feed lamp will come on if the pH indicated is below the pH “set” level. 5.
6.3 Set-points not being reached or maintained * Factory setting for feed time is 0.6 sec on with 5 minute delay. Feeders may require longer feed time. If time is too short, set-points will not be maintained. If time is too long, overfeeding chemicals will occur. Correct time is dependent of multiple factors such as pool/spa water volume, feeder output, chemical concentration and chemical needs. * Controllers are designed to maintain set-points.
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.
