Installation & Operations Manual
SECTION 1 Installation Instructions
1. How the DEL Spa Ozone Generator Works
DEL Ozone Generators produce ozone gas which is introduced to
the spa water through suction created by the spa. Tubing is used
to connect the Ozone Generator to an injector or a vacuum port
provided by the spa manufacturer. The injector or port are vacuum
sources used to pull the ozone gas out of the Ozone Generator
and into the water. At no time should water come in contact with
the Ozone Generator. To protect the Ozone Generator from water
traveling backwards through the tubing connection, the unit must
be mounted and plumbed as described in this manual.
