4. MAINTENANCE & SERVICE
4A.System Electromechanical Overview
CAUTION Disconnect power before performing service. Refer to the IMPORTANT SAFETY INSTRUCTIONS displayed in
the front of this manual. Refer to Figures 4, 5, and 6.
4A-1. Ozone Generation System
The AOP Pro is constructed with one or two ozone cells, each powered by its own high voltage, high frequency power supply.
The ozone cells are mounted on a water cooled heatsink block that is thermally protected.
4A-2. Gas Lines
Air enters through the air lter, is compressed and sent to the oxygen concentrator, where it is dried and nitrogen is removed.
Oxygen exits the concentrator and passes through the gas owmeter and oxygen check valve before entering the ozone
cell(s). Ozone is generated in the cell(s), continues out through the gas output valve, exits the enclosure and ozone check
valve to arrive at the injector in the process water line.
4A-3. Injector Plumbing
Refer to Figures 1 and 2. Water owing through the injector generates a vacuum that draws ozone into the water. The amount
of vacuum is based on the velocity of the water which can be adjusted using the injection adjustment valve (and optional,
customer supplied, booster pump). The resulting gas ow rate can be observed on the gas owmeter.
4A-4. Degas Management System
Water and gas exit the injector and enter the degas management system, which separates undissolved gas from the water.
Undissolved ozone is vented through the degas valve and returned to oxygen by use of the catalytic ozone destruct. Ozone
enriched water then exits the mixing degas vessel (MDV) and enters the input of the AOP Pro.
4A-5. UV Reactor
There are two lamps in each UV reactor of the AOP Pro powered by an energy ecient electronic ballast. Ozone enriched
water enters the UV reactor and is exposed to UV-C causing AOP reactions to take place. The water exits the UV reactor to
return to the process plumbing.
4B. Ozone System Maintenance
4B-1. Air Filter
The air lter must be inspected and cleaned monthly, at a minimum. Replace quarterly. Twist the air lter cap and lift o to
expose lter element.
4B-2. Check Valves
The oxygen and ozone check valves must be replaced a minimum of once per year. Order valve replacements and swap into
position, noting ow direction as shown on the valve body.
WARNING Trace amounts of nitric acid may be present in check valves, ozone cells, O-rings and gas lines. Wear proper
safety equipment (skin and eye protection) and avoid direct contact with any condensation in used parts.
4B-3. Ozone Cells and O-rings
Replace ozone cell O-rings and inspect ozone cells a minimum of once per year. Each ozone cell uses two O-rings. Order
replacement parts and swap into position as shown in Figure 5.
4B-4. Compressor
The compressor must be serviced a minimum of once per year. Order compressor rebuilt kit and perform service according
to manufacturer’s instructions.
4B-5. Gas Lines
Inspect the gas lines and replace as needed. If there is evidence of water leaking past the ozone check valve toward the ozone
cells, shut down the AOP Pro immediately and drain and dry the gas lines. As necessary, replace the ozone check valve and/
or gas output valve to prevent future issues. If water entered the ozone cells they will need to be replaced.

4. MAINTENANCE & SERVICE
Figure 5: Ozone Cell and O-ring Service
CAUTION: Always disconnect power to the AOP Pro prior to performing service.
4C. UV Reactor Service and Maintenance
• Each UV Reactor contains two UV lamps and two quartz tubes.
• The UV lamps are designed to provide proper germicidal ecacy for 16,000 hours.
• The UV lamps may continue to glow well beyond 16,000 hours but will not provide proper intensity and must be
replaced to ensure ecacy.
• The UV lamps are housed in a quartz tube. If the quartz tube becomes dirty, its ability to transmit UV rays from the
lamp will be diminished.
• The service interval for the quartz tube is dependent on pool water chemistry and some pools may require more
frequent cleaning than others.
• Initially, inspect the quartz tube after 750 hours of use and clean as needed. Subsequent cleaning intervals can be
increased or decreased based on the condition of the quartz tubes or observed water conditions.
4C-1. UV Lamp Removal
1. Open the enclosure door.
NOTE: The AOP Pro will not operate while the enclosure door is open.
2. After allowing adequate time for the UV lamps to cool, disconnect the UV lamp from the connector on the ballast.
3. Grasp the UV lamp wires and gently pull until the top of the UV lamp has pulled past the lamp retainer tabs.
4. Pull slowly on the white ceramic end of the UV lamp until the bottom has pulled past the lamp retainer tabs. If the
UV lamp is dicult to remove, use a slight twisting motion or remove the lamp retainer. AVOID TOUCHING THE
UV LAMP GLASS WITH YOUR BARE HANDS. Oils on your hands can cause hot spots on the UV lamp and shorten
its life. Use a soft clean cotton cloth or clean cotton gloves to handle the UV lamp. Carefully place the UV lamp in a
clean, dry, and safe location. Clean the UV lamp if necessary with alcohol and repeat this process for the other UV
lamps.

4C-2 Quartz Tube Removal and Cleaning
NOTE: For instructions on cleaning without mechanical disassembly, see Appendix.
1. If the AOP Pro is mounted below the water level, system isolation valves must all be CLOSED to prevent excess water
from draining into the unit.
2. Loosen main inlet and outlet ttings on the AOP Pro, this should allow sucient water to drain from the AOP Pro.
3. Before continuing, allow adequate time for the UV lamps and quartz tubes to cool.
4. Remove the UV lamps as described in Section 4B-1.
5. Remove the front lamp retainer screws using the hex key included in the parts kit and remove the lamp retainer.
6. Grasp the quartz tube and pull it outward to remove it from the UV reactor.
NOTE: Additional water will drain from the UV reactor when the quartz tube is removed.
7. Remove the sealing O-ring from the quartz tube and set aside.
8. Wipe all residue from the quartz tube. If calcium deposits are encountered, use a mild solution (4:1) of water and
muriatic acid (available at pool supply stores), or household calcium/lime remover.
Follow the directions for use and handling of muriatic acid on the acid bottle label. Use proper eye and
skin protection and avoid breathing acid fumes.
NOTE: DO NOT USE ABRASIVE CLEANERS as they can scratch the high quality quartz glass. After cleaning the quartz tube,
wash it o and wipe dry. Inspect the quartz tube for cracks. Replace if cracks are found. Make sure the inside of the quartz
tube is dry before replacing the UV lamp(s).
NOTE: DAMAGES CAUSED BY BROKEN QUARTZ TUBES ARE NOT COVERED UNDER THE LIMITED WARRANTY.
Figure 6: UV Lamp and Quartz Tube Removal
4C-3 Quartz Tube Installation
1. Place a sealing O-ring approximately 1/2in (12.7mm) from the end of the quartz tube. Insert quartz tube into the UV
reactor until it is fully seated.
NOTE: If the end of the quartz tube is protruding from the UV reactor, the alignment is o. Remove and re-insert
the quartz tube to seat it properly as shown in Figure 7.
2. Place the lamp retainer over the quartz tube and attach the lamp retainer using the lamp retainer screws and
