1SAFETY WARNINGS

THESE INSTALLATION AND OPERATION INSTRUCTIONS SHOULD BE READ

COMPLETELY BEFORE INSTALLING OR OPERATING THIS EQUIPMENT / SYSTEM.

THIS MANUAL ASSUMES:

•YOU ARE ALREADY TRAINED AND COMPETENT IN THE SAFE USE AND HANDLING OF

INDUSTRIAL GASES / CRYOGENIC FLUIDS AND CRYOGENIC / ELECTRICAL EQUIPMENT!

•YOU ARE FAMILIAR WITH THE RISKS ASSCOCIATED WITH EXTREME LOW

TEMPERATURES!

•YOU ARE FAMILIAR WITH THE RISKS ASSOCIATED WITH ASPHYXIATION AND LOW

OXYGEN ATMOSPHERES!

Persons handling cryogenic liquids (liquid nitrogen, argon or carbon dioxide) should be

aware of the dangers associated with their extreme cold and also the possibility of

asphyxiation should large volumes of liquid or gas be discharged in confined or poorly

ventilated areas. Persons handling liquid oxygen must also be aware of its potentially

hazardous oxidising properties. Carbon dioxide additionally has toxic properties.

CARBON DIOXIDE (CO2) IS TOXIC. O2 MONITORING SYSTEMS SHOULD NOT BE USED FOR

CO2 MONITORING. CO2 CONCENTRATIONS WILL BECOME DANGEROUSLY TOXIC BEFORE

AN O2 MONITORING SYSTEM WILL REACT. A DEDICATED CO2 MONITOR SHOULD BE USED

TO PROTECT AGAINST CO2 ENRICHMENT.

USE APPROPRIATE PERSONAL GAS MONITORS WHEN WORKING.

ONE O2 OXYGEN MONITOR ALARM UNITS Page 3 of 21.

Standard equipment must NOT be used with liquid oxygen. Only equipment which has been

specially cleaned and specifically labelled as `CLEANED FOR OXYGEN SERVICE’ may be used

with liquid oxygen. This is due to the increased risk of fire or spontaneous combustion in

pure or enriched oxygen environments.

Safety information provided by the suppliers of the industrial gas / cryogenic liquid must be

read and understood before and followed during the installation and operation of this

equipment. Failure to observe all safety precautions may result in property damage, personal

injury, and/or death.

DO NOT TOUCH COLD SURFACES OR LIQUID WITH BARE SKIN.

Cryogenic liquids are extremely cold and exposure of skin or eyes to liquid, cold gas or cooled

objects may result in severe cold burn injury. The use of eye / face protection, insulated

gloves, appropriate clothing and footwear is required. Take time to consider these and other

safety precautions that must be observed.

Siren beacons can be extremely loud, >110dBA. Wear appropriate ear protection if working

with or close to active siren beacons. Consider others working nearby.

Failure to correctly maintain the equipment / system could result in the equipment / system

failing to operate correctly. Calibration should only be performed by persons trained and

approved by Quantum Cryogenics.

The equipment must be used only for the purpose and in the manner described in these

instructions. If used for other purposes or in a manner not specified protection provided by

this equipment may be impaired. The equipment must not be used as a critical component

in life support devices or systems.

ELECTRICAL SHOCK CAN KILL

Isolate all power supplies before opening enclosures or attempting to connect / disconnect

equipment. Items may have multiple power sources which may include, but are not limited

to, internal battery, dedicated low voltage power supply, external low voltage power supply

(with or without battery back-up). Power may also be supplied from repeater units or other

ancillary items connected.

ONE O2 OXYGEN MONITOR ALARM UNITS Page 5 of 21.

All electrical installation must only be carried out by a qualified electrician or other suitably

qualified and competent person.

Take extreme care if handling the PCB, THE ASSEMBLY IS EXTREMELY FRAGILE. Protect it

from damage and electro static discharge.

2INTRODUCTION

The ONE O2 monitor continually monitors the air surrounding the sensor on its base and

provides visual and audible alarms when the monitored concentration of oxygen passes pre-

set `Alarm’ levels.

There are 3 models of ONE O2 monitor units for different oxygen deficiency and enrichment

applications. Please ensure you have correctly identified the model type and refer to the

appropriate sections of this manual. To identify the model type check the text adjacent the

red LEDs on the face plate.

Low / Critically Low

For oxygen deficiency applications

Alarm 1 Set 19.5% LOW OXYGEN ALARM

Alarm 2 Set 18.2% CRITICALLY LOW OXYGEN ALARM

High / Critically High

For oxygen enrichment applications

Alarm 1 Set 22% HIGH OXYGEN ALARM

Alarm 2 Set 23% CRITICALLY HIGH OXYGEN ALARM

High / Low

For combined enrichment and deficiency applications

Alarm 1 Set 22% HIGH OXYGEN ALARM

Alarm 2 Set 18.2% LOW OXYGEN ALARM

Please note the alarm thresholds shown above are the current default settings. Older

equipment may have different alarm thresholds. Please refer to the calibration certificate for

threshold settings specific to an item of equipment.

3INSTALLATION

The ONE O2 monitor should be fitted adjacent to the gas source. The monitor should be

wall mounted by fixing firmly to a clean, dry, vertical surface using appropriate fixings.

When deciding where to position the monitor, consideration should be given to:

[i] whether the alarm lights and audible alarm can be easily seen and heard, and

[ii] whether the unit is placed so that it is monitoring the required area adequately.

Take care to ensure that the monitor is not installed above items such as work tops or other

equipment and cannot be obstructed or blocked-in by any item which may restrict the free

flow of air around the monitor.

The monitor should be located at a height appropriate for the monitoring conditions. For

oxygen deficiency applications where the inert gas has a relative density greater than air the

monitor should be positioned 1m above floor level. For inert gases with a relative density

lower than air (helium) the monitor should be positioned as high as practicable. For oxygen

enrichment applications the monitor should be positioned 1m above floor level.

The ONE O2 base unit monitors the surrounding air by natural convection and diffusion into

the oxygen sensor through the sensor filter in its base.

IT IS IMPORTANT TO ENSURE THAT THE SENSOR FILTER IS NEITHER COVERED NOR BLOCKED

and that

AIR CAN CIRCULATE FREELY AROUND THIS FILTER AND THE BASE OF THE UNIT.

The ONE O2 monitor must not be exposed to, immersed in or sprayed with water, rain,

solutions or other solvents.

For wiring information please refer to the CryoPanel 4 manual.

4OPERATION

The ONE O2 monitor is powered by internal (non-rechargeable) batteries. It operates

continuously and has no ON / OFF switch.

If the Low Battery condition is observed the ONE O2 monitor should be withdrawn

from service immediately as it may no longer operate correctly. A replacement Sensor-

Battery Pack (Part number ONE O2-RS) should then be fitted.

The Sensor-Battery pack within the ONE O2 monitor must be replaced on or before the date

shown on the label which is found on the side of the product. The sensor –battery pack has

a 3-year life and should be replaced every three years. Older versions may have a 2 year

battery and sensor.
