Key Plumbing System Component Overview (cont.)
Mazzei Eductor
The Mazzei Eductor is a very basic
vacuum generator. Water passes
through it at a high rate. The shape
of the mazzei is similar to the “V”
shape of a venturi. Water rushes
through pulling the check valve
inward drawing in ozone from the
ozone generator. If the outbound line
becomes restricted - water flow at the
outlet will drop off and a vacuum error
will occur shutting down the ozone
generator and oxygen concentrator.
Stainless Steel Check Valve
This check valve is found on the
ozone inlet tubing. It is a safety
device to prevent the possibility of
any water backflowing to the ozone
generator in the event that the mazzei
check valve failed.
NOTE: Ozone
tubing is PVC. Never replace with
polyflow or alternative type. Ozone
will “eat” the tubing from the inside.

Ozone (O3) Flow from
the Ozone Generator:
The ozone gas flows
down through the check
valve & is drawn into the
mazzei where it mixes
with the treated water.
Oxygen Concentrator & Ozone Generator
These components were covered on pages 35 and 36 in this manual in
depth. If any questions, please re-visit those pages.
Pressure Switch
The Pressure Switch is physically located on the
left side of the control box, and, arguably could be
covered in key electrical components. The poly pick
up tube is connected above the pump outlet on the
manifold. If the pump pressure is lower than 4psi,
the switch will let the PLC know and shut the pump
off on a low pressure fault.
NOTE: It’s a good idea
to clean the tube once per year.
