System Shutdown Procedures
CAUTION:
The ozone generator operates at high voltage. Follow these steps carefully before performing any
semi-annual or annual maintenance procedures.
Step 1:
Turn off power to any peripheral system hydraulic components.
Step 2:
Turn the Main Power switch on the SC27P to the “OFF” position. The Main Power LED’s on the control panel
should not be illuminated.
Step 3:
Disconnect the power to the ozone system either at the service disconnect box (if so equipped) or main circuit
breaker.
Semi-Annual Procedures
CAUTION:
Follow system shutdown procedures (outlined above) before performing any of the following steps.
Air Preparation System
•
Air Inlet Filter: Replace the air compressor inlet filter. See Appendix-Section A for location.
Note:
Manufacturers' recommended replacement interval is 4,000 hours of operation. Operating conditions in
the equipment area will dictate the required frequency of this procedure
.
Annual Procedures
CAUTION:
Follow system shutdown procedures before performing any of the following steps.
Air Preparation System
•
Compressor: Following the procedures outlined in the compressor rebuild kit, rebuild the two compressor heads.
See Appendix-Section A for location.
Note: Manufacturers' recommended interval is 5,000 to 12,000 hours of
operation.
Compressor performance and/or operating conditions in the equipment area will dictate the
required frequency of this procedure.
Ozone Generator
•
Cooling Fan Filters: Clean or replace the cooling fan filter elements as required.
Note: Fan filter stainless steel
cover must be removed to access fan filters.
•
Depressurization Valve:
Rebuild the depressurization valve, see Appendix-Section A for location.
•
Check Valve: Replace check valve located behind the system control panel, see Appendix-Section A for location.
•
Reaction Chambers: Remove and disassemble one reaction chamber according to the steps outlined below (see
Figure 8-2). Check the chamber interior and dielectric tube for oil, dirt or moisture.
Note: CWT pressurized
reaction chambers are anodized blue.
Removal and Disassembly
Note: Disassembly and service of the reaction chamber is a technical, delicate and critical procedure. Please
consult your ClearWater Tech dealer before attempting this procedure.
Step 1:
Make sure all power to the ozone generator has been disconnected according to the “System Shutdown
Procedures” outlined above.
Step 2:
Unplug the electrical connections from the drive module.
Step 3:
Disconnect tubing connections from the fittings on both ends of the reaction chamber.
Step 4:
Remove reaction chamber from ozone generator.
Step 5:
Disconnect the high voltage lead from the drive module.
Step 6:
Remove retaining screws from the two end caps (4 each).
Step 7:
Using a gentle back-and-forth twisting motion, remove the non-high voltage end cap (the one
without
the white
power lead attached) from the heat sink/cathode assembly.
Note: The stainless steel clamp must not be
removed.
Step 8:
Remove the high voltage end cap and dielectric from the heat sink/cathode assembly.
Note: The stainless steel
clamp must not be removed.
Step 9:
With contact brush attached, remove the brush adapter nut from the high voltage end cap.
