Operator Startup - Ozone Solutions Waterzone Series Installation & Operation Manual

Ozone System Initial Startup
Procedure
IMPORTANT: Read and understand the "Caution,
Warnings and Hazards" section of this manual be-
fore operating the Ozone System!
1. As a safety measure, ensure that the Variable
Ozone Output is set to "0" during initial setup
and first starting of the system (so that ozone is
not produced).
2. Open the water valves on the piping system to
allow water flow into the system and fill the
Contact Tank. The Contact Tank is full when
water is visible in the Air Vent. Water seen
here also ensures that the pumps are primed
with water. IMPORTANT: Do not start the
system unless it is full of water, as equipment
damage may result in the event of a dry start.
3. Inspect all water connections for leaks.
4. Allow water to flow through the system by
opening a valve downstream of the system.
WATER FLOW light will turn green
(signifying adequate flow).
5. Start the Ozone Injection System by pressing
the SYSTEM start button on the screen. The
following will occur automatically: the INJEC-
TION PUMP light will turn green and the In-
jection Pump will start, the INJECTOR INLET
pressure gauge should rise higher than the tank
pressure, and the O2 CONC light will turn
green (ozone will not be produced due to the
variable output turned all the way down).
6. Ensure that the Ozone Generator oxygen flow
does not exceed the limits outlined in the man-
ual. Setting the flow to about 6-8 SCFH is a
safe starting point for this flow. This flow is
adjusted manually using the flow control valve
near the flowmeter, and may be affected by
varying water pressures. Normally if adequate
water pressure is applied to the contact tank
the oxygen flow will not exceed its limits.
7. Ensure that air bubbles are escaping from the
air vent; this will indicate the oxygen is being
introduced into the water and off-gassed effec-
tively. Normally, a small amount of water will
periodically exit the air vent along with the
air. If adequate off-gassing does not occur, the
tank will eventually fill with oxygen/ozone
gas and cause injection pump cavitation and
result in low dissolved ozone levels. It may
take a matter of minutes or hours for such a
problem to become obvious.
8. The Variable Ozone Output may be turned up
at this time to begin producing ozone.
9. The Dissolved Ozone Level on the Dissolved
Ozone Monitor should being to rise within
five (5) minutes of startup. NOTE: The dis-
solved ozone sensor will require time to stabi-
lize in the process before full accuracy is
reached. Normally this occurs within a few
hours, but may require more time. See AS-500
Dissolved Ozone Monitor (AV88) and Sensor
operation manuals for details.
10. Depending on the application, the Dissolved
Ozone Monitor settings may need to be ad-
justed for the HIGH and LOW alarms. See the
System Operation section of this manual.
11. To stop the system simply press the SYSTEM
stop button on the screen. The system will
automatically shut down.
12. Do not disconnect power to the system unless
necessary. Certain components will require
warm-up before operation if power is discon-
nected.
