Maintenance and Service

4A. System Electro-Mechanical Overview

Refer to Figure 4 for component locations.

4A-1. 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 proper vacuum being supplied from the venturi injector. Light will be lit for either low or high vacuum conditions.

4.High Coolant Temperature: Red light indicates coolant temperature is over 150°F - resulting from loss of cooling water flow. (Refer to TROUBLE- SHOOTING section.)

5.HighTransformerTemperature: Red light indicates transformer temperature is over 150°F - resulting from high current through the transformer. (Refer to TROUBLESHOOTING section.)

6.Water Backflow Detected: Red light indicates wa- ter backflow from injector into generator. (Refer to TROUBLESHOOTING section.)

4A-2. Remaining External Components

1.Main Power Switch: Power switch is used for sys- tem start-up and shut-down. Switch activates the control system allowing the generator to start up.

2.Flowmeter: Flowmeter controls and indicates the oxygen flow through the system.

3.Circuit Breaker: Circuit breaker protects the gen- erator from over current conditions. Push the breaker button to reset.

4.ORP Controller (optional): ORP controller receives a millivolt (mV) signal from the ORP sensor mounted in the process water line. ORP (Oxidation-Reduc- tion Potential) is a measure of the relative oxida- tion strength of the water. As ozone is added to the water system the ORP level will rise. As ozone is used up in the water system the ORP level will drop.The ORP controller continuously analyses the sensor signal, compares it to the setpoint that has been programmed, indicates the ORP level on the digital display, and relays the signal to the ozone generator.

5.Variac (Optional):Variac adjusts high voltage power supplied to the ozone generator module controlling ozone output concentration.

4A-3. Internal Components

1.Corona Discharge (CD) Module: Generator module consists of stainless steel water jacket and ground tubes and two end housings. Enclosed inside the module are the high voltage glass tube electrodes.The top end housing (the cylindrical glass chamber) encloses the high voltage connection for the electrodes and allows for visual inspection.

2.High VoltageTransformer(s):Transformer raises supplied voltage up to the voltage necessary for ozone production.Transformer is thermally protected by a temperature switch attached to the transformer casing.

3.Air Compressor: Compressor produces and supplies compressed air to oxygen concentrator.

4.Oxygen Concentrator: Supplies concentrated, dry, oxygen feed gas to the ozone generator.

5.Lo Limit Vacuum Switch: If the vacuum in the ozone output supply line falls below 2 in. Hg the switch will open causing the system to shut down.

6.Hi Limit Vacuum Switch: If the vacuum in the ozone output supply line rises above 10 in. Hg the switch will open causing the system to shut down.

7.Water Backflow Detector: Backflow detector senses water present in ozone tubing in generator. If water is detected, system will close solenoid valve to prevent additional water backflow from occuring.Water in the generator will cause severe damage to the high voltage electrodes.

8.Ventilation Fan: Cooling fan operates when main power switch is “ON”.

9.Air Filter: Filter cleans ventilation air entering the enclosure.

10.Door Interlock Switch: Interlock switch will shut down entire system if door is opened. Securing the door will bring the system back into operation.

11.Relay Panel: Contains control relays for system interlocks, indicator lights and main power control.

4B. Preventative Maintenance Schedule

The Infinity™ Corona Discharge ozone system requires very little maintenance beyond general housekeeping practices.

DAILY:

1.Check ozone generator for proper operation.

-Make sure no red indicator lights are lit.

-Make sure flow meter is indicating proper air flow.

2.Practice normal pool maintenance.

MONTHLY:

1.Remove and clean ORP probe.

-Remove from water stream.

-Clean tip of probe with non-abrasive cleanser to remove any contaminant build up on probe.

-If there is a heavy build up on probe surface, clean with a mild muriatic solution.

-Rinse and return to water stream.
