MDV for EC-10, EC-20, and EC-40

SECTION 1. General Information

The DEL MDV (Mixing Degas Vessel) system:

Prevents virtually all ozone bubbles from returning to the pool,

eliminating bubble noise and visibility.

Allows application of higher ozone concentrations.

Protects pool components such as covers, fittings and surfaces.

Prevents bubbles from gathering under the cover or inside plumbing.

Utilizes a Granulated Activated Carbon (GAC) destruct cartridge to

destroy excess ozone gas removed by the MDV.

SECTION 2. Installation (refer to Figure 1)

NOTE: The MDV will not be as effective in systems with back

pressures in excess of 10 psi. Oversized pumps and small returns

should be avoided.

1. Follow ozone generator mounting and electrical connection

instructions in Eclipse manual.

2. Mount the MDV vertically as shown in Figure 1 to a solid surface

(i.e. fence, wall, post) using the (2) cable ties, (4) cable tie

mounts, and (4) screws included. Use a pair of pliers to tighten

and secure the cable tie. If trimming away excess, fold tab over

to avoid the sharp edge. To avoid discoloration, mount in an area

out of direct sunlight.

3. Mount the (GAC) Cartridge vertically to a flat surface using (2) #6

screws.

NOTE: Mount the cartridge close enough to the MDV so that the

tubing can be connected from the cartridge to the top of the MDV.

4. Install By-Pass plumbing as shown in Figure 1. Use the

appropriate By Pass Valve based on your pump type:

a. For Single Speed pumps install the adjustable 2-Way Valve.

b. For Two-Speed or Variable Speed pumps, install a DEL Check

valve.

5. The recommended return configuration is a dedicated line from

the MDV to the pool. If a dedicated return is not available, a

return to the main line may be used.

6. An additional valve may be installed either before or after the

MDV to act as a drain for winterizing or maintenance.

7. Screw the Tube Adapter onto the injector using thread sealant if

needed. Do not use thread tape.

8. Connect the Ozone Tube Assembly to the Tube Adapter on the

Injector. Be sure that the end with the check valve installed is

connected to the Injector.

9. Attach the other end of the check valve and tubing assembly

to the ozone outlet on the Eclipse. Be sure the flow direction is

away from the Eclipse.

10. The drain at the base of the Destruct cartridge will release small

amounts of condensation and carbon under normal operation.

To avoid water or carbon stains, connect tubing to the bottom of

the Destruct and divert the condensation to a suitable location.

11. Allow all PVC glue to dry completely per manufacturer’s

instructions before running water through MDV.

SECTION 3. Operation

1. The gas flow must now be optimized. Refer to Section 2 of your

Eclipse manual for instructions on adjusting water flow to achieve

proper gas flow.

2. The water level inside the MDV should be near the bottom

edge of the MDV Top Endcap. Use the Level Control Ball

Valve installed at the MDV outlet to adjust the water level (see

Troubleshooting section).

NOTE: For Variable Speed pumps, the water level in the MDV

may drop completely at low speeds. The Level Control Ball

Valve may be closed slightly to raise the level. However, this

may impair injector performance at higher speeds. Verify proper

operation under all conditions.

3. Streams of gas bubbles should be rising to the top of the MDV,

and the water returning to the pool should be virtually bubble

free.

4. If the pool equipment is mounted above water level, it is normal

for water to drain from the MDV when the main circulation pump

turns off. The MDV should return to normal operation shortly after

the system comes back on.

SECTION 4. Troubleshooting

Symptom: The water level in the tower is only around half full, or

steadily dropping.

There is not enough backpressure downstream of the MDV to

should be avoided.

1. Follow ozone generator mounting and electrical connection

instructions in Total Eclipse manual.

2. Mount the MDV vertically as shown in Figure 2 to a solid surface

3. Mount the GAC Cartridge vertically to a flat surface using 2 #6

screws.

NOTE: Mount the cartridge close enough to the MDV so that the

tubing can be connected from the cartridge to the top of the MDV.

4. Plumb the Total Eclipse and MDV to the pool return line as

indicated in

Figure 2. Use thread sealant as needed. Do not use thread

tape.

NOTE: Be sure that the flow direction arrow on the Del Check is

correctly oriented with the direction of water flow.

5. The recommended return configuration is a dedicated line from

the MDV to the pool. If a dedicated return is not available, a

return to the main line may be used.

6. An additional valve may be installed either before or after the

MDV to act as a drain for winterizing or maintenance.

maintain water level in the tower. -- Plumb in a small ball valve

downstream of the MDV. Close it off to the point where the proper

water level in the tower is maintained.

Symptom: Large bubbles are visible at the bottom of the tower, and

are at the pool return.

The gas flow rate is too high. -- Reduce the gas flow through the

injector, by slowly turning the handle on the Bypass Valve towards

the open position. Ensure that the flow-meter ball is still bouncing in

the flow meter.

SECTION 5. Maintenance

1. The MDV itself is maintenance free. The destruct cartridge must

be replaced every 12 months of operation. A new cartridge can

be ordered from your dealer/distributor using DEL part number

9-0620.

2. Winterizing, if necessary, can be done by draining water from

MDV.

7. The drain at the base of the Destruct cartridge will release small

amounts of condensation and carbon under normal operation.

To avoid water or carbon stains, connect tubing to the bottom of

the Destruct and divert the condensation to a suitable location.

SECTION 3. Operation

1. Begin with the Level Control Ball Valve in the half open position.

Follow system start-up instructions in Total Eclipse manual. Turn

off the pool’s main circulation pump, and allow the Total Eclipse

to run on its own. At this point water will be flowing through the

MDV, but not filling up the tower.

2. Adjust the Level Control Ball Valve until the water level inside the

MDV is near the top of the intersection of the clear PVC tower

and the molded top cap.

3. Restart then shut down the pool’s main circulation pump several

times, ensuring that the water level in the tower remains at the

top of the tower both when the main circulation pump is on and off.

SECTION 4. Troubleshooting

Symptom: There is no water in my MDV.

The pump in your Total Eclipse has stopped running -- Refer

to the troubleshooting guide in your total eclipse manual.

SECTION 5. Maintenance

1. The MDV itself is maintenance free. The destruct cartridge must

be replaced every 12 months of operation. A new cartridge can

be ordered from your dealer/distributor using DEL part number

9-0620.

2. Winterizing, if necessary, can be done by draining water from

MDV.
