Operation Guidelines - Ozone Solutions Waterzone Series Installation & Operation Manual

Section 3
System Operation
IMPORTANT: Read and understand the "Caution,
Warnings and Hazards" section of this manual be-
fore operating the Ozone System.
Water Flow
Water flow through this Ozone Injection System
will be dependent upon the supply water connec-
tion to maintain pressure on the system. The ozone
injection will occur regardless of the rate of flow
through the contact tank, as long as the tank re-
mains full of water.
Higher water usage will result in lower dissolved
ozone levels, while lower water usage will result in
higher dissolved ozone levels. This is due only to
the ratio of ozone to water. Keep this in mind
when specific dissolved ozone levels are required
for your operation.
Water Pressure
This Ozone Injection System will not operate ef-
fectively with water pressures exceeding 50 PSI. If
water pressures are higher, then water pressure
should be regulated ahead of the ozone system so
that it can be adjusted to maintain lower pressures.
If the water will be used for spraying or washing
purposes, the water pressure should be kept below
30 PSI. This is to ensure that the ozone will remain
dissolved into the water. Higher spray pressures
will off-gas a large amount of the dissolved ozone
from the water in the spraying process. This is not
a desirable situation for the disinfection process, or
for human safety.
Injector Pump
The Injector Pump is a dedicated pump to mix the
ozone with the water. This pump will create the
necessary pressure differential across the Venturi
Injector to create the necessary vacuum to draw
ozone into the water stream. This pump will also
mix the ozone with the water in the contact tank by
recirculating this water through the injector at a
flow rate necessary for injection. This pump will
start and stop automatically and should be operat-
ing any time that the dissolved ozone level in the
water is below the high setpoint.
System Control
Read the "Ozone System Controls and Indicators"
to become familiar with the individual compo-
nents before attempting to operate the system. The
system can be operated from a remote location if
the optional external control connections are used.
For more information see the "Installation: Op-
tional Electrical Connections: section in this man-
ual.
Local Operation
For normal day-to-day operation, the Initial
Startup Procedure may be followed. The system
can be started by pressing the START button on
the screen; all other controls will automatically
start as necessary.
Remote Operation
There are external connection terminals located
inside the system controller that can START or
STOP the system from a remote location. The ex-
ternal push buttons can START or STOP the sys-
tem by momentarily closing the contacts. This
may be convenient when there is another control
system that will be starting other equipment asso-
ciated with the Ozone System.
