    For your protection, read all instructions carefully before installing or operating this automatic controller. The Polaris Watermatic C316 24-Volt Controller is designed to ® automatically monitor and maintain the sanitizer level and pH balance in swimming pools, spas and any circulating water sys- tem that requires water chemistry management.

  • Page 5: Pre-Installation

    IV. Pre-installation Before installing the controller, it is important to do a site assessment and consider where and how you will mount the unit. The controller should be mounted on a wall or other sur- face at least ten feet away from the edge of the water and less than six feet from the GFCI power source.

  • Page 6: Switch Settings

    B. Switch Settings 1. Dip switches #1 and #2 control the feed times. Feed times vary depending on whether the controller is in the pool or spa mode. Note: Once the settings have been modified, move the Pool/Spa Switch on the front of the controller to the appro- priate mode to activate the changes.

  • Page 7: Installation

    B. Controller Installation The voltage on the feeder solenoid valve must match the output voltage of the controller. The C316 Controller must be matched with a 24V solenoid valve. 1. Turn off the power to the filter pump at the breaker box.

  • Page 8: Flow Cell Installation

    7. Replace the Caution Plate at the bottom of the controller. 8. We recommend that the sensor be installed in the Flow Cell Assembly (part #9-700), available from Polaris. If you do not use the flow cell assembly, you can install the sensor using the compression fitting that comes with the controller.
  • Page 9 There are three suggested methods to install the flow cell. 1. Plumb the inlet to the flow cell after the filter and plumb the outlet of the flow cell after the heater using the saddle clamps provided. See the Pressure Differential Installation diagram.
  • Page 10 3. Plumb from before the filter to after the heater, using an inline filter to minimize debris coming into contact with the sensors. See the Pressure Differential Alternative Installation diagram. Pressure Differential Alternative Installation Controller Heater To Pool From Pool Flow Filter pH Sensor...
  • Page 11 The flow cell comes fully assembled in the box. It is setup to use with the 3/8" tubing provided; however, other sized tubing or 1/2" hard plumbing can be used. To use alternative tubing, remove the 90° on/off valves and plumb according to the appli- cation.

    D. Sensor Installation Carefully unpack the ORP and pH sensors and remove the plastic pro- tective cap(s) from the sensor tip(s). Store the protective cap(s) inside Controller the controller enclosure for future use when winterizing or reshipping.

    3. Make sure the power switch (Figure 4, #2) is off and the ORP selection knob (Figure 4, #9) is rotated counterclock- wise to the lowest setting. 4. Turn on the filter pump and then the controller power switch. The red power light (Figure 4, #1) and indicator lights on the controller light bar array (Figure 4, #8) will come on.

  • Page 14: Ph Calibration

    H. pH Calibration 1. Take a clean sample of pool water and place the pH sensor into the water sample. 2. Push the pH display button (Figure 4, #10). The yellow ORP lights on the scale indicator light (Figure 4, #3) will go out and the green pH scale indicator lights will come on.

    VII. Operation The controller will only operate during the filtration cycle. A. Setting Feed and Delay Times 1. The controller is preset at the factory with the following feed and delay times: Pool Setting: Feed = 1 minute, Delay = 30 second Spa Setting: Feed = 10 seconds, Delay = 30 seconds These settings can be adjusted as needed to maintain the pool balance.

  • Page 17: Out-Of-Range Indicator

    C. Out-of-range Alert When the ORP is out-of-range (less than 100 mV) for ten con- secutive minutes, the lowest red light on the light bar array will flash and the controller will not activate the feeder. Depending on the level of ORP, the manual feed button may be used to raise the ORP level.

  • Page 18: Maintenance

    VIII. Maintenance A. Testing 1. Test the sanitizer and pH levels with a test kit weekly or more frequently as required by local health codes. 2. Adjust the pH in the pool or spa as needed to maintain a level between 7.4 and 7.6. B.

  • Page 19: Checking The Orp Sensor

    C. Checking the ORP Sensor 1. The ORP sensor should be checked every six months or anytime the feeder oversanitizes the water. 2. Clean the sensor tip as noted previously. 3. Place the sensor in a clean glass of tap water. This should give a reading between 200 and 400 mV.

  • Page 20: Erosion Feeder Operating Tips

    IX. Erosion Feeder Operating Tips • Feeders must be sized properly. When automating an existing system, multiple feeder may be required. The feed- er should be able to attain desired levels in short operating cycles. Automation becomes ineffective if the feeder must run for prolonged periods.
  • Page 21 the solenoid valve opens, the initial flow from the feeder may significantly increase (spike) the sanitizer level in a small body of water. For this reason, it may be desirable to use the timed-feed feature, which opens the solenoid for a short period, then delays the next feed cycle until the initial feed is distributed throughout the pool/spa system.

  • Page 23: Guidelines For Using Orp For Water Maintenance

    XI. Guidelines for Using ORP for Water Maintenance Why should I maintain a pH level between 7.4 and 7.6? pH levels below 7.4 can cause eye irritation, metal cor- rosion, etching of plaster, stains, damage to vinyl liners, and loss of sanitizer. In addition to eye irritation, pH lev- els above 7.6 can cause cloudy water, scale formation and loss of sanitizer efficiency (low ORP).
  • Page 24 How do I make sure the ORP sensor is working properly? Watch the sensor reading when adding sanitizer. If it does not respond properly, follow the recommended cleaning procedures, see Maintenance. If cleaning does not solve the problem, check the sensor as outlined in the Maintenance section.
