HOW THE DEL SPA OZONE GENERATOR WORKS
Ozone is introduced to the spa water through suction created by the spa. The
tubing that is attached to the ozone generator is connected to the spa via an
injector or to a port labeled “ozone” by the spa manufacturer. When your system
comes on in the water filtration mode, water travelling through the venturi injec-
tor creates a vacuum that pulls the ozone out of the ozone generator and injects
it into the water. At no time does water come in contact with the ozone
generator. When your filtration system is in the off mode gravity may cause
water to travel back in the tubing towards the ozone generator. To prevent water
from reaching the ozone generator, a one-way check valve must be installed in
the tubing. This check valve only allows the flow to go one way from the ozone
generator to the injector. To further prevent water from backing up into the ozone
generator, form a “Hartford” loop in the ozone supply tubing and hang the loop as
high as possible in relation to your spa’s water level (see pages 8 & 11).
