2. Detach quick-connect wire from the Aclarus Ozone Enclosure going to flow switch.
3. Remove flow switch assembly from unit.
4. Examine flow switch for the presence material interfering with the flow switch.

Tape the flow switch, and replace flow switch in ‘T’ plumbed into the system and
make sure the switch is not inserted past the point identified in step 8.
NOTE : Ensure flow arrow on flow switch points in the direction of the water flow in
the pipe.
