USE INSTRUCTIONS AND LIMITATIONS

Each person using this equipment must read and understand the information in these User Instructions before use. Use of this

equipment by untrained or unqualified persons, or use that is not in accordance with these User Instructions, may adversely affect

product performance and result in sickness or death.

The Macurco OX-6 Oxygen Detector provides oxygen detection and automatic ventilation control in wastewater treatment plants,

factories, storage facilities and other commercial applications. The normal concentration of oxygen in the atmosphere is approximately

20.9% by volume. The OSHA minimum acceptable breathing air contains 19.5% oxygen. In the absence of adequate ventilation the

level of oxygen can be reduced surprisingly quickly by breathing, combustion and other processes. Oxygen levels may also be depleted

due to dilution by other gases such as carbon dioxide, nitrogen or helium and chemical absorption by corrosion processes and similar

reactions. Alternately, increased levels of oxygen may dramatically increase the flammability of any combustible matter. If oxygen levels

exceed 24% volume, even materials such as clothing which might normally just smolder may burst into flame. The risk from oxygen

enrichment exists where pure oxygen is stored; for example in hospitals and industrial gas manufacturing and distribution plants. The

OX-6 meets the OSHA requirements for oxygen concentration. OX-6 can be used stand alone, with the Macurco DVP-120 Detection

and Ventilation Control Panel, other 12 VAC or 24 VDC fire/security panels or building automation systems.

Use only for monitoring the gas which the sensor and instrument are designed to monitor. Failure to do so may result in exposures to

gases not detectable and cause sickness or death. For proper use, see supervisor or User Instructions, or call Technical Service at 1-

877-367-7891.

Do Not Use For

The OX-6 is not intended for use in hazardous locations or industrial applications such as refineries, chemical plants, etc. Do not mount

the OX-6 where the normal ambient temperature is below 0°F or exceeds 125°F (below -18C or above 52C). The OX-6 mounts on a

4x4 electrical box supplied by the contractor. Do not install the OX-6 inside another box unless it has good air flow through it.

This equipment may not function effectively below 0F or above 125F (-18C or above 52C). Using the detector outside of this

temperature range may adversely affect product performance and result in sickness or death.

The OX-6 is a low voltage, dual relay oxygen (O2) detector and automatic ventilation controller. The OX-6 uses a microcomputer

controlled, electronic system to measure the concentration of oxygen, actuate relays and provide a 4-20mA output. The OX-6 has a

field replaceable, electrochemical sensor (expected life of 2+ years) and optional calibration test kit. The OX-6 is a low level meter

capable of displaying from 0-25% of oxygen.
