OZONE SUPPLY TUBING CONNECTION LOCATIONS:

OZONE-READY SPAS

If your spa is factory equipped with an ozone injection point, follow the

manufacturer’s installation instructions. Check with your dealer. After installa-

tion, you will need to test the suction at the injection point. Refer to the

section titled “DEL Suction Test” for instructions on performing this test.

NON OZONE-READY SPAS:

LOCATION “A” & “B” (see Figures 2 & 3): These are the most common

connection locations. The assembly procedures are the easiest and sufficient

ozone dispersion is provided. They can be used if the air control valves

completely close.

LOCATION “C” (see Figure 2): This location is used if the air control valve

does not have a defined closed position.

LOCATION “D” (see Figure 5): This connection procedure is used on spas

which have a two-speed pump and where the venturi air line is inaccessible or

will not provide sufficient suction to operate the ozone generator properly. A

DEL RIGID INJECTOR MANIFOLD (DEL Part Number IU-201) is required and

can be ordered from your local dealer. This connection is also used if an air

blower is provided to “supercharge” the jets.

LOCATION “E” (see Figure 5): Use this location on spas with a single-speed

pump. A DEL ADJUSTABLE INJECTOR MANIFOLD (DEL Part Number IU-

206) is required and can be ordered from your local dealer.

Locations “D” and “E” provide the most efficient method for dispersing

ozone into the spa’s water.

OZONE SUPPLY TUBING CONNECTION:

Once a suitable location has been chosen, follow the appropriate connection

instructions below.

LOCATIONS “A”, “B”, “C”:

NOTE: In the case where there are two air control valves, it may be helpful to

determine which one has the best air suction. To do this, operate the pump on

low speed with both air control valves open. Observe the action of the jets.

The lowest jet with the most bubbles will suggest the best location in the air

venturi line for the ozone supply tubing connection.
