The ozone injector is to be installed upstream of the DEL AOP Spa so
the ozone can pass through the UV reactor. This interaction leads to
advanced oxidation process which will improve sanitation. However,
the DEL AOP Spa will function properly if the ozone injector is
installed downstream.
a. Connect ozone compatible tubing (1/4” internal diameter) to the
open hose barb on the DEL AOP Spa
b. Run tubing to the ozone injector or appropriate vacuum source.
i. If the DEL AOP Spa is mounted above the water line, tubing
may be run directly to the vacuum source.
ii. If the DEL AOP Spa is mounted below the water line, run
tubing to a point above the water line and back down to the
vacuum source.
c. Install the check valve in the tubing above the water line. Ensure
flow direction is from the DEL AOP Spa to the vacuum source.
d. Secure all tubing connections with hose clamps.
