BALBOA ULTRAZONE OPERATION
• Ozone will turn on during the programmed filter cycles and
pump #1 operation.
• Verify that the green light on the Ozone turns on when
activated.
• Check the spa drain (at the bottom of the spa) to verify that
small ozone bubbles are coming out.
• Verify that one way check valve is installed on the ozone
tubing, and it is working as intended.
