4.4 Electrical installation
4.4.1 Wire the panel
Potential Electrocution Hazard. Always disconnect power to the instrument when making
electrical connections.
The controller supplies power to the sensors and the digital gateway.
1. Remove power from the controller.
2. Connect the pH sensor (optional) wires to the gateway. For information on how to install sensors
in the flow cells, or how to connect the sensor to the gateway, refer to the sensor user manual.
3. Connect the chlorine sensor to the gateway. For information on how to connect the sensor to the
gateway, refer to the sensor user manual. Carefully read the labels on the cable connectors to
avoid mismatches.
Note: When the panel is shipped, the chlorine sensor cable is taped to the front of the panel near the location
of the sensor connection.
4. Connect the controller to the gateway with the 1 m connector cable that is supplied with the
panel. Connect the controler to the power source only when all other connections are finished
and checked.
4.5 Plumbing
4.5.1 Plumb the panel
Make sure to follow the size specifications for all panel tubing and fittings. The flow path must
increase in diameter as water flows through the system to prevent build-up of backpressure.
on page 6 shows an overview of the plumbing connections.
1. Attach tubing to the sample inlet and outlet fittings.
2. Make sure the cleaning port on the chlorine flow cell is closed.
3. Make sure the grab sample port on the pH flow cell is closed.
4. Install chlorine and pH (optional) sensors according to the instructions foun in the corresponding
user manuals, prior to running the sample through the system.
5. Open the flow valve on the sample line and allow water to move through the system.
6. Make sure there are no leaks from the tubing, valve fittings or the flow cells.
7. To minimize air bubbles, the pH flow cell may be tilted between 0º and 30º as shown in
