3 SECTION 1 General Information The DEL MDV (Mixing Degas Vessel) allows for a higher concentration of ozone to be used on a spa while preventing virtually all ozone bubbles from returning to the spa, eliminating bubble noise and visibility. The MDV eliminates unused ozone from returning to the spa; eliminates the potential of ozone reacting with spa components such as covers, pillows, fittings, or surfaces; and prevents bubbles from gathering under the cover or inside the plumbing. The MDV system utilizes a GAC destruct cartridge that destroys ozone gas removed by the MDV. Installation instructions for spas using Recirculation Pumps are on pages 1-2 and for 2-Speed Pumps are on pages 3-4. Disclaimer - This model of MDV is designed to be installed in place of an injector in above Ground spas with a recirculation system flowing between 3 and 8 GPM and at pressures below 10 PSI. This unit must be plumbed below the water level in order to work properly. Note that in all instances where ozone injection takes place below water level, check valves are necessary in ozone gas lines. DEL recommends periodic replacement of your check valves to protect you ozonator investment. For spas using a 2-speed pump, rather than a recirculation system, or for recirculation systems flowing in excess of 8 GPM, plump the MDV in a side stream configuration as detailed in figure 2. Because spas and plumbing systems can vary greatly, it is impossible for DEL to recommend a specific check valve pressure that will work in all systems. Experimentation may be required to find the optimal solution for a given spa system. For plumbing systems above the surface of the water, a different model MDV (MDV-10) is required. NOTE: Use ozone resistant materials for all plumbing connections. SECTION 2 Mounting the MDV and GAC Cartridge 1. Find a suitable location for the MDV under the spa. Allow one or two inches above and several inches below the MDV for plumbing. 2. Mount the MDV vertically to a solid surface using (2) tie straps, (4) tie strap mounts, and (4) #14 screws as needed. 3. Mount the Granular Activated Carbon (GAC) Cartridge vertically. It can be attached directly to the MDV using (1) tie strap, or to a flat surface using (2) #6 screws. 1

Under normal operation, gas and moisture will flow out of the bottom of the GAC cartridge. Run another piece of flexible tubing from the bottom of the GAC cartridge to a return fitting in the spa. DEL Ozone recommends a dedicated fitting a few inches below water level. 5. Install hose clamps at all tube connections. SECTION 3 Plumbing (Dedicated* Recirculating Pump) *Recirculation Pump should pull directly from and return directly to the spa. Other plumbing configurations may affect MDV operation.

Use appropriate fittings (not provided) to connect the outlet of the recirculation pump to the Water Inlet of the MDV. 3. Connect the Water Outlet of the MDV to a dedicated return fitting on the spa. FROM OZONE GENERATOR WATER OUTLET SECTION 4 Plumbing (2-speed pumps) 1. Disconnect power to the spa. Drain water if necessary. 2. Attach DEL Pressure Regulator to Water inlet of MDV. Use appropriate fittings (not provided) to connect the outlet of the 2-speed pump to the pressure regulator prior to any manifold, if possible. 3. Connect the water. 4. Connect the Water Outlet of the MDV to a dedicated return fitting on the spa. INJECTOR PORT WATER INLET (FROM RECIRC. PUMP) CONDENSATE DRAIN SECTION 5 Ozone Generator Installation 1. Mount the DEL Ozone Generator and make electrical connections as directed in the ozone generator manual. 2. Use 1/4 or 3/8 ID flexible tubing to connect the ozone outlet on the Ozone water level, if possible. Figure 1: Recirculation Pump Installation 2 3

SECTION 6 Operation 1. Allow any PVC glue to dry completely per manufacturer s instructions before running water through MDV. 2. Start the spa circulation system. Check for leaks and verify proper operation (Note: Do not run heater until proper function is confirmed).

Verify that pump is operating correctly. Remove any kinks of obstructions from water line. Symptom: No suction from ozone generator a. Verify that ozone check valve is facing correct direction. b. Remove any kinks or obstructions from ozone line. c. Remove return jet fitting and/or replace with larger size. SECTION 8 Maintenance 1. The MDV is maintenance free. The GAC Cartridge must be replaced every 12 months of the operation. A new cartridge can be ordered from your dealer/distributor using the DEL part number Winterizing, if necessary, can be done by draining water from MDV. 3. If necessary, replacement Tie Straps and Tie Strap Mounts can be ordered from your dealer/distributor using DEL part numbers and , respectively.
