MAINTENANCE
CHAPTER 8
Maintenance of the ozone system is critical to its longevity and operating efficiency. While all system
components are built to provide years of reliable service with minimum maintenance, following the
procedures outlined below is strongly recommended.
All maintenance procedures have been segmented by interval: daily, monthly, semi-annual and annual.
Daily procedures involve quick, visual checks for changes in normal operating conditions. Monthly,
semi-annual and annual procedures include cleaning and/or replacement of certain critical parts.
NOTES:
•
The ozone generator warranty states that it “does
not extend to any product or part which has been
damaged or rendered defective as a result of use of
parts not sold by ClearWater Tech, or service or
unit modification not authorized by ClearWater
Tech” Please contact your ClearWater Tech dealer
if you have any questions about any maintenance
procedure
before
you begin that procedure.
• CAUTION
:
Observe all common safety practices
and review the “Safety Warnings and Instructions”
in Chapter 2 before attempting any maintenance
procedure that requires the use of tools and/or
shutting down the ozone system.
Daily Procedures
Ozone Generator
•
Indicator Lights: Check all indicating LED’s on the control panel of the SC27P. See Appendix-Section A for
location and See Figure 7-1A for Control Panel LED function.
See Troubleshooting Guide as required.
•
Air Flow: Check the air flow meter on the SC27P control panel. Make sure air flow is within the CFH (cubic feet
per hour) range shown on the “Ozone generator air flow” line of the “Pneumatic Operating Parameters” (see
Figure 7-2). Adjust if necessary by following steps outlined in the “Start-Up & Calibration” section.
•
Pressure: Check the PSI gauge located on the ozone generator cabinet door. Make sure pressure is within the
range shown on the “PSI Gauge” line of the “Pneumatic Operating Parameters” chart (see Figure 7-2). Adjust if
necessary by following steps outlined in the “Start-Up & Calibration” section.
Vacuum Break
•
Water Level: Check the water level in the vacuum break. Make sure it is
above
the flapper valve in the overflow
tube. If the vacuum break must be refilled with water disconnect the External Loop from the SC27P and shut
down the system and follow the steps outline in Chapter 6 “ Installation Procedures – Pneumatic.” Then re-start
the system by following the steps outlined in Chapter 7 “Start-up and Calibration Procedures.”
Injection Manifold
•
Check Valve: Inspect the Teflon
ozone delivery line that runs between the vacuum break and the check valve
assembly on the suction port of the ozone injector manifold. If water is observed in the delivery line near the
check valve assembly, the check valve has failed. See Troubleshooting Guide.
Monthly Procedures
Ozone Generator
•
Cooling Fan Operation: Check to make sure the two cooling fans (mounted on the bottom panel of the SC27P.)
and the two exhaust fans (located behind the air preparation compressor) are operating. If not, refer to the
Troubleshooting Guide.
•
Cooling Fan Filters: Check the cooling fan filter elements (mounted on the bottom of the SC27P) and clean as
required. Operating conditions in the equipment area will dictate the frequency required for this procedure.
Remove the filter element and clean with soap and water, drying them completely before re-installing (see Figure
8-1).
Note: Fan filter stainless steel cover must be removed to access fan filters.
Booster Pump(s)
•
Strainer Baskets: Check and clean the strainer basket in the booster pump(s) as required (if so equipped).
