HOW THE DEL SPA OZONE GENERATOR WORKS Ozone is introduced to the spa water through suction created by the spa. The tubing that is attached to the ozone generator is connected to the spa via an injector or to a port labeled “ozone” by the spa manufacturer. When your system comes on in the water filtration mode, water travelling through the venturi injector creates a vacuum that pulls the ozone out of the ozone generator and injects it into the water.
Connecting ZO-300/302: Insert lamp cartridge straight into power supply, being careful to align pins, and bonding plate (on back). Press power supply and lamp cartridge together. CAUTION: DO NOT TWIST cartridges while pushing them together. Twisting will damage the OZONE GENERATOR which could lead to premature failure. Attach the two cartridges by securing the bonding plate to the lamp cartridge. Use the included self-tapping screw and star washer.
OZONE SUPPLY TUBING CONNECTION LOCATIONS: OZONE-READY SPAS If your spa is factory equipped with an ozone injection point, follow the manufacturer’s installation instructions. Check with your dealer. After installation, you will need to test the suction at the injection point. Refer to the section titled “DEL Suction Test” for instructions on performing this test. NON OZONE-READY SPAS: LOCATION “A” & “B” (see Figures 2 & 3): These are the most common connection locations.
INSTALLATION FOR LOCATIONS “A” & “B”: Turn off the electrical power and drain the spa at least 12 inches below the selected “A” (Figure 2) or “B” (Figure 3) location. The installation instruction for locations “A” & “B” are identical except that location “A” utilizes a vertical air venturi line and location “B” utilizes a horizontal air venturi line. Use the spa’s venturi air line which provides the best suction and is connected to the lowest jet. (See NOTE on page 5).
PLASTIC HOSE CONNECTOR INSTALLATION: A plastic hose connector installed onto the air venturi line may be used when the spa is not “ozone ready”. The plastic hose connector can be purchased from your dealer using DEL part number 7-0127 (see Figure 7). Select a convenient location, that provides enough room to work, to install the PVC tee fitting with 1/2” female threads (not included). Cut the existing air venturi line at the selected “A” or “B” location (see Figures 2 & 3). Glue the fitting into place.
INSTALLATION FOR LOCATION “C”: Turn off the electrical power and drain the spa at least 12 inches below the air venturi line which provides the best suction and is connected to the lowest jet. Cut the PVC flex tube approximately 3” to 4” from the air control valve. Install an appropriately sized PVC reducer fitting (not included), with 1/2” female threads on one end. Be sure to use FLEX-TO-RIGID- PVC Cement whenever working with PVC flex tubing.
Turn off the electrical power and completely drain the spa. The DEL RIGID INJECTOR MANIFOLD must be installed in the spa’s return line after all other equipment (pump, filter and heater). It should be installed as close to the spa as possible. Figure 6: Injector Mounting Diagram Locate an appropriate section of the return line, hold the injector manifold against the pipe and mark the length. Subtract 2-2/3” from the overall length, mark this point, and cut out the section.
Attach the check valve assembly to the ozone generator cartridge. Be sure the check valve bevels are pointed towards the spa and away from the DELZONE unit - you should be able to blow air through the tubing in one direction. See ELECTRICAL CONNECTION to complete installation. When the final electrical connections are completed, refill the spa to its normal operating level (check for leaks as the spa is filling), and turn the power back on.
FAILED DEL SUCTION TEST Very little or no suction may be caused by the list of possible problems below. Review the list then test for suction again. 1. Dirty filter: Clean the filter and test again 2. Clogged jets: Clean and test again 3. Closed adjustable jets: Open completely and test again 4. Jet nozzle orifices too small: Remove orifice reducers or drill larger orifices. 5. Injector Manifold installed before heater or pump: All Injector Manifolds must be installed AFTER all spa support equipment.
The spa’s mechanical system will run exactly as before. Note: If the pump is above the water level of the spa and there is not a flapper valve in the strainer basket housing, the pump may lose its prime on an injector installation. Most pump/filter systems have this valve. If yours does not, add a DEL CHECK 1/3# check valve (DEL part number C0-0101, not included) between the spa outlet and the strainer basket housing. Continue to follow the instructions for the pump, filter, heater, etc.
Figure 9: SpaECLIPSE/CDS-16 Ozone Chip Replacement REPLACING THE LAMP CARTRIDGE (ZO-300/302) 1. 2. 3. 4. 5. Turn off the electrical power. Remove the ozone generator from the holding clamps. Remove the ozone supply tubing from the generator cartridge. Loosen the bonding plate screw. Remove the lamp cartridge by gently pulling the ozone generator apart to separate the cartridges. Wiggling the cartridges slightly will help separate them. CAUTION: DO NOT TWIST the cartridges while separating.

TROUBLE SHOOTING SYMPTOM: No blue light glowing in chip or lamp cartridge PROBABLE CAUSE CORRECTIVE ACTION 1. No power to unit 1A. Check power source and cord 2. Broken or defective 2A. Replace chip or lamp cartridge chip or lamp cartridge 3. Defective power supply 3A. Return to dealer for warranty cartridge (ZO-300/302) replacement SYMPTOM: Blue light glowing but no ozone smell on water surface PROBABLE CAUSE CORRECTIVE ACTION 1. Ozone is present but smell 1A.
5. Too much suction 5A. Adjust the jets to reduce suction 6. Dirty, loose, cracked filter 6A. Check/replace filter as needed 7. Metals or minerals in water 7A. Ozone may react with metals/minerals in the water (this is common when new water is added) causing cloudy water. Check alkalinity, pH, and clean filter. Run filtration system and ozone for 24 hours and clean filter. SYMPTOM: Pump loses prime when system is off PROBABLE CAUSE CORRECTIVE ACTION 1. No flapper valve in pump 1A.
