Cooling Water
Cooling Water Flow: .1 Gpm (.4 Lpm)
Colling water Pressure: 15–40 psi (103–275 kPa)
Cooling Water Temp.: 5–90˚F (10–32˚C)
1/4" FPT connections are supplied on the
generator. See Figure 4, 5a, 6a. Be sure that
the tubing is appropriately matched with the marked
inlet and outlet ports. Carefully match and connect
to water plumbing as shown in Figure 4. Alternate
method using connections at injector may be used.
SECTION 3 Operation
Initial System Start-Up
Upon completing all of the generator system
connections, you are ready to begin start-up
procedures.
1. Check electrical fittings.
2. Check for proper voltage.
3. Turn on circulation pump.
4. Check for leaks.
5. With the ozone isolation valve closed, adjust the
injector bypass valve and/or filtration sidestream
valve to flow water through the injector.
6. Check cooling water.
7. Open the ozone isolation valve.
8. Turn main power switch to "ON" position.
9. Adjust injector by-pass to attain required vacuum.
(Red "Vacuum" light will go out.) Gas flow
(as indicated by the flow meter on the door of
the unit) should correspond with the rating listed
for the specific model on the specification label.
Normal Operation
With the power switch on, the system's
compressors and cooling fans will start-up, the
oxygen concentrator will begin operating, and
the output solenoid valve will open. With the
injector adjusted to attain the correct gas flow,
the ozone generator should be producing ozone
and injecting it into the process line.
Both (2) green indicator lights should be lit. If
an optional ORP Controller is installed, it should
be displaying a reading from the sensor probe
and will automatically cycle the generator on and
off as needed to maintain water quality. Residual
ORP levels will vary per application.
However, the system will not start under any of
the following conditions:
1. The system will not start-up if the door is not
secured. A door interlock switch is incorporated
into the system enclosure.
2. If the optional ORP/DO3 controller is installed the
system will not produce ozone if the measured
level is already above the setpoint of the controller.
3. The system will not produce ozone if there is not
enough vacuum being generated by water flow
through injector. The red "Vacuum" light will go
out when proper vacuum is attained.
If you experience complications, see APPENDIX
A, TROUBLESHOOTING GUIDE or call
800.831.7133 for assistance.
System Shut-Down
The ozone generator is a specialized water
cooled device that must be properly protected
during shut-down/storage periods. The
following sequence of steps must be used for
servicing or for storage.
1. Toggle the main system power switch to the
"OFF" position to shut-down generator.
2. Close the ozone isolation valve to prevent water
back flow.
3. After the generator has been shut-down, the
process water circulation pump may be turned
off.
4. If the system is going to be shut-down and
stored during freezing weather, it is very
important that the cooling water be drained to
protect it from rupture or damage.
NOTE: Process water flow must not be shut-
down when the ozone generator is operating.
Doing so may cause water to backflow into
the system and damage the generator cells.
SECTION 4 Maintenance & Service
System Electro-Mechanical Overview
Refer to Figure 5a and 6a for component locations.
Indicator Lights
1. Main Power: Green light indicates that power is
being supplied to the ozone generator.
2. Ozone Power: Green light indicates that power
is being supplied to the high voltage Corona
Discharge circuits and that ozone is being
produced.
3. Vacuum: Red light indicates a low vacuum fault
condition. (Refer to APPENDIX A
TROUBLESHOOTING).
4. High Coolant Temperature: Red light indicates
