Follow these steps

  1. Remove the waste line from the Purge Out port on the flowmeter and from the waste outlet port.

  2. Connect the new waste line to the Purge Out port.

  3. Route the line through the groove in the drain port wall into the waste outlet port.

    To avoid false leak alarms, the waste line must sit properly in the waste outlet port. If it does not, liquid may accumulate in the drain port and activate the leak sensor.

  4. Reinsert the seal wash detector assembly.
