1. Unscrew the connector cap from the controller. Retain the connector cap to seal the
connector opening in case the sensor must be removed.
2. Push the connector into the socket.
3. Hand-tighten the union nut.
Note: Do not use the middle connection for the sensors as this is reserved for the display module.
The turbidimeter body is designed for wall-mounting (although it may be mounted on the
optional floor stand). The turbidimeter sensor must be mounted within six feet of the
controller unless an extension cable is used. Maximum cable length is 9.6 m (31 feet).
