Owner`s manual

Turn off the electrical power and completely drain the spa. The DEL RIGID
INJECTOR MANIFOLD must be installed in the spa’s return line after all other
equipment (pump, filter and heater). It should be installed as close to the spa
as possible.
Figure 6: Injector Mounting Diagram
Locate an appropriate section of the return line, hold the injector manifold
against the pipe and mark the length. Subtract 2-2/3” from the overall length,
mark this point, and cut out the section. Install the injector manifold with PVC
cement. The injector manifold can be installed in either a vertical or horizontal
position in the return line.
Make sure the water flow arrow on the ball valve is pointed toward the spa.
Locate the plastic hose connector, wrap 3 layers of teflon tape on the threads
(do not use thread sealant), and install it hand tight into 1/2” female pipe
thread fitting of the DEL Rigid Injector Manifold. Tighten the plastic hose
connector 1/2 turn with a wrench. Secure one end of the ozone supply tubing
to the barb end of the plastic hose connector with a supplied gold hose clamp.
Locate the ozone supply check valve and install it into ozone supply tubing
by cutting tubing in two separate places approximately 4’ from the ozone
generator and insert the check valve between each cut, securing both ends of
the check valve with gold hose clamps as shown in Figure 7.
