For installation into spas with water capacity up to 1,000
gallons. Plumbs into most all ozone-ready spas or the spa return line. Injects ozone through venturi when the spa circulation system operates.

For spas where the air venturi is inaccessible, inconveniently
located, or provides insufficient suction, a DEL injector
manifold may be used. These installations are also used if an
air-blower is used to "supercharge" jets.
