INSTALLATION
DANGER
Electric Shock Hazard. Be sure to turn power OFF and disconnect from power source
before any work is performed. Failure to do so could result in serious injury or death.
PREPARATION
Open the unit door and locate the bracket that mounts the ozone modules and power supplies – most
of this subassembly will be replaced
.
NOTICE
The wire harness will be reused and does not need to be removed from the unit during
service. Take care not to damage any wires or connectors during the process.
DISCONNECTING THE MANIFOLD
Locate the ozone outlet barb. On the inside of unit, remove tubing clamp and disconnect the manifold
tube from the ozone outlet barb.
WARNING
Trace amounts of nitric acid may be present in the tubing. Wear proper safety equipment
(gloves and eye protection) and avoid direct contact with any condensation in the line.
REMOVING THE OZONE SUBASSEMBLY
(Refer to Figure 1)
1. Disconnect all the ozone module power connectors.
2. Loosen the terminal block from the ozone bracket by removing the two mounting screws.
3. Loosen the line filter (ECE models only) from the bracket by removing the two mounting screws.
4. Remove the two mounting nuts of the ozone bracket and remove the bracket with ozone modules,
power supplies and manifold.
5. Carefully remove zip-ties as necessary to free subassembly from unit.
6. The wire harness, terminal block and line filter (ECE models only) will remain in the unit.
INSTALLING THE NEW SUBASSEMBLY
(Refer to Figure 2)
1. Install the new bracket subassembly using the nuts previously removed.
2. Mount the line filter (ECE models only) to the new bracket using the screws previously removed
3. Mount the terminal block to the new bracket using the screws previously removed.
NOTICE
For DEL Ozone 25 and 50, the terminal block requires 90° rotation to mount to the new
bracket – the unit wire harness will allow it to reach but it may require adjustment and/or removal of
zip-ties.
4. Connect the new ozone module power connector(s) to any of the available positions.
RECONNECTING THE MANIFOLD
1. Ensure that the new manifold is connected to all ozone modules.
2. Install new tubing clamp over the new manifold tube, connect tube to the ozone outlet barb and
secure with new tubing clamp.
SYSTEM STARTUP
Restore power to the unit and check proper operation, including that the ozone module light(s) are
illuminated. Close unit door.
