Plumbing – Vacuum System (refer to Figure 1)
• Most spas are factory equipped with an ozone injector or vacuum port, like the one
shown in Figure 1. Review your spa’s installation manual to identify the correct ozone
connection location.
• If the spa is not equipped with an injector (vacuum source), A2Z Ozone Systems provides
a wide range of optional installation kits.
• Contact A2Z Customer Service for assistance at 502-499-4977 or visit

Plumbing – Ozone Generator (refer to Figure 1)
• Connect shorter PVC ozone tubing (8 inch) provided to the hose barb on the ozone
generator side.
• Connect other end to the check valve.
• Connect longer PVC tube to the other end of the check valve and run to the injector.
• Observe the flow arrow on the check valve and ensure that the flow direction is into the
injector vacuum source.
• Connect the other end of PVC tube to injector suction. Run the spa and pump and check
the vacuum before connecting PVC tube to injector.
• If there is no vacuum at suction then you will need to check the injector or pump water
flow.
• Do not connect ozonator if there is no vacuum at injector suction.
• Slide hose ties on each end into the tubing.
• Secure all tubing connections with the hose ties.
NOTE:
If the Aquatic 2 is mounted below the water line, run tubing to a point above the
water line and back down to the vacuum source. Secure tubing in this position.
