Watermatic® Dichlor Systems

The most unique automated feeder system on the market.

The Watermatic D-1 and D-6L are exclusive dry chlorine feeder systems with an electronic controller that provides an ORP and pH readout to assure ideal sanitizing levels using granular dichlor. The system will adjust chlorination levels automatically in response to a variety of changing conditions. Exact dosing ensures bather protection and reduces costs.

Two systems available:
Watermatic D-1; includes a C1500 electronic controller and a G1000 dichlor feeder. Reads chlorine and pH level, feeds chlorine automatically.

Watermatic D-6L; includes a C2000 ORP/pH controller, a G-1000 dichlor feeder, and a 3-310 peristaltic acid pump. All of the benefits of the D-1, but also feeds liquid acid.

CHEMICAL BALANCE: Chemical use is excessive.

1. High TDS, nitrates, etc.

2. High organic loading (leaves, insects, small animals, etc.).

CHEMICAL BALANCE: The sanitizer level is too high.

1. Check the pH level. High pH levels depress the ORP reading.

2. Algaecide or another additive can depress the ORP reading.

3. TDS or cyanuric acid levels may be too high.

CHEMICAL BALANCE: The sanitizer level is too low.

1. PH level is too low. Low PH levels increase ORP readings.

2. Algaecide, non-chlorine shock or other additive is elevating the ORP signal.

CONTROLLER: No lights are illuminated on the controller and the controller is shut down.

1. Check the power to the controller.

2. Contact a service company for assistance.

CONTROLLER: Proper Operation?

If the controller is operating properly, one or two lights will be lit on the light bar display (digital display on the C660). The power light will also be illuminated and the feed light will be on.

CONTROLLER: The feed light is off or the power light is off, and the display lights are on, but the controller is shut down.

Check the flow switch or the jumper flow terminal on the back of controller.

CONTROLLER: The low ORP light is on and the controller is shut down.

The controller automatically shuts down when the ORP reading is less than 100 mV.

1. Check the sensor.

2. There may not be sanitizer in the pool or feeder. Add sanitizer to the pool to raise the ORP reading above 100 mV.

FEEDER: The ORP controller reading is below the set point and the chlorine is low in the pool.

1. The feeder is clogged or there are lumps in the sanitizer. Remove the measuring cup lid, clean it and break up lumps or replace the material.

2. The solenoid may not be working. Check the wiring for corrosion or other damage.

3. Test the sensor and replace it if necessary.

4. Fill the feeder if it is empty.

5. Blown fuse or solenoid stuck. Replace the fuse after freeing the solenoid.

6. Adjust dip switch settings on the controller that prevent feeding. These switches can be set to prevent ORP feed when pH feeding or when readings are out of range.

FLOW: The gray ball in the flow indicator is not moving or is moving slowly, and the controller ORP reading is above the set point, but the chlorine in the pool is low.

1. If the water in the main tank is more than an inch below the dam, the problem is on the inlet side (top tube).

a. The in-line screen/filter may be clogged. Clean the filter.

2. If the water is near the top of the dam, the problem is on the outlet side (bottom tube).

a. The main filter may need to be backwashed.

b. There might be a blocked tube on suction side (lower tube). Purge the lower tube.

c. There may be a pool filter system problem.
