INTRODUCTION AND OVERVIEW

This manual is intended to provide basic installation, operation, and maintenance guidelines

for the operator of the MIOX® 1.0 and 2.0 on-site generator (OSG). Variations between

model types may cause the images in this manual to not directly reflect the setup of every

unit.

Properly operating and maintaining the system will increase cell life and overall system

performance. If you encounter problems or have questions not covered in this manual,

please contact De Nora WT Service at 1-800-646-9426.

Regulatory Compliance

U. S. Environmental Protection Agency (US EPA)

On-site generated oxidants are listed as a compliance technology for water disinfection. To

be listed as a compliance technology, the system must be cost effective and achieve

compliance with the regulated maximum contaminant levels (MCLs), and the operator must

be capable of reliably operating the technology. The on-site oxidant category was added to

this list in 1997 primarily based on independent research of De Nora WT.

List of Registrations

EPA Establishment Number: 48482-TX-001

NSF International

De Nora WT maintains a policy of verification and compliance of De Nora WT for water

applications. The NSF Standard provides the criteria used to evaluate the public health

safety of materials, components, products, or systems that contact drinking water, drinking

water chemicals, or both. For details of specific NSF standards for specific MIOX®

equipment, please consult with De Nora WT. NSF listings are also available through NSF

International at (800) NSF-Mark or their web site at www.nsf.org.

State Approvals

De Nora WT maintains a policy of obtaining state regulatory approval in all states where

MIOX® equipment is installed and operated. De Nora WT has never been rejected for

approval in any state. For a complete list of states currently approving on-site oxidant

technology, please contact De Nora WT.

European Union Conformity

The MIOX® 1.0 and 2.0 systems comply with the protection requirements of EU Council

Electromagnetic Compatibility (EMC) Directive 2014/30/EU and Low Voltage Directive (LVD)

2014/35/EU, as well as meet the requirements of EU Council Directive 2011/65/EU on the

restriction of the use of certain hazardous substances in electrical and electronic equipment

(“RoHS recast” or ”RoHS 2”). The full text of the system EU declaration of conformity is

included in the document kit along with this manual and can also be provided on request.

System Description

The MIOX® 1.0 and 2.0 system is an on-site chemical generator that creates mixed oxidant

solution from water, salt, and electricity. The system can create either 1.0 lb. or 2.0 lbs. of

Free Available Chlorine (FAC) per day, depending on the model ordered. When producing

oxidant, the MIOX® system is automatically controlled by a pair of level switches inside the

oxidant storage tank.

Mixed oxidant solution is a powerful hypochlorite-based disinfectant with improved biological

kill efficacy that achieves more rapid and thorough inactivation of a wide range of microbial

contaminants.

Oxidant Tank

Vented oxidant solution storage tank for OSG output.

Hydrogen Vents

Upward-sloping piping connected to outside environment for venting potentially dangerous

hydrogen gas (See Hydrogen Safety White Paper).

Level Switch Assembly

Assembly of two level switches and a level switch cable. The level switches control the OSG

when installed in the oxidant tank. The 15’ cable connects the level switches, and pressure

switch to the OSG. See Figure 2 for details. Note: The level switches are orientation-

sensitive and must be installed with the arrow pointing upward in order to function properly.

System Cover

A rigid plastic housing that covers and protects the key components of the MIOX® 1.0 or

2.0 OSG.

LCD Display

Visual Display with a cycling menu of system status and operational parameters. See Figure

3 for details.

LED Indicator

A multi-color LED which displays system status. See Figure 3 for details.

Electrical Enclosure

An actively-cooled aluminum box housing the control board, power supplies and other

electronic components of the MIOX® 1.0 or 2.0 OSG System. See Figure 3 for details.

Brine Pump

An automated peristaltic pump which controls the system’s brine flowrate and acts as a

check valve to prevent brine supply dilution. Capable of withstanding up to 10 PSI of

pressure. See Figure 3 for details.

Water Pump

An automated peristaltic pump which controls the overall system flowrate and acts as a

check valve to prevent oxidant from flowing into the water supply. Capable of withstanding

up to 10 PSI of pressure. See Figure 3 for details.

MIOX® 1.0 or 2.0 Electrolytic Cell

A proprietary electrolytic cell manufactured by De Nora WT produces 1.0 lbs of FAC per day

of runtime. 1 lb. MIOX® OSGs use one cell while 2 lb. MIOX® OSGs use two cells. See

Figure 4 for details.

Thermowells

In-line temperature sensors used to evaluate operational efficiency of the system. See

Figure 4 for details.

Electrical Back Panel

All of the unit’s electrical connections, including the power switch, system fuse, IEC power

receptacle, and connectors for the Level Switch Assembly, a USB jump drive, and an

Ethernet cable. See Figure 5 for details.

Plumbing I/O Panel

3 barb fittings for connecting the water supply, brine supply and oxidant outlet. See Figure

5 for details.

Hydrogen Vent Kit

Kit of parts consisting of an oxidant tank inlet, drop tube assembly, warning labels and a

vent strainer. Refer to the Oxidant Tank Manual for details.

Inline Pressure Reducer & Switch Kit

Assembly to reduce line pressure to an appropriate pressure for the OSG. Additionally, the

Kit includes a Pressure-Switch that connects to the level switch assembly. This switch will

shut the unit down to prevent damage if the system loses feed-water pressure. The kit has

a female ¾” NPT inlet connection. See Figure 7 and Appendices for details.

Integrated Brine Tank (Optional)

Optional integrated tank with automatic brine generation system designed explicitly for the

MIOX® 1.0 and 2.0. See Integrated Brine Tank Manual for installation and operation.

NOTE: For items not listed above see the appendices and

Documentation Kit. Additional items may include, but are not limited

to the oxidant tank, hydrogen vent, oxidant pump, water heater and

water chiller. Contact De Nora WT for additional details on available

options.
