Ecotechnics Gas Regulator information sheet.
Gas Regulator
Bolt the brass regulator onto a CO bottle.
2
Make sure you have the Fibre washer on before
you tighten up the connection to the gas bottle.
Plug the Unis/Evolution CO2 Controller flying lead into the
regulator, not forgetting the rubber seal.

CO Regulator Diagrams
2
Ordinary outside air normally contains CO at
2
a concentration of about 300 ppm (300 parts
of CO gas per million parts of air.) Indoors,
2
however, whether we're at home, office, or
traveling in a confined space like a plane, the
CO content can vary considerably. Usually in
2
a home, the CO levels can vary as much as
2
300 - 2000 ppm. Several studies have
indicated that CO does not seriously impact
2
human health until levels reach approximately
15,000 ppm. This level is more than 40 times
greater than the normal concentration of
atmospheric CO . At extremely high levels,
2
i.e., 30,000 ppm, (these concentrations are
usually never reached in a standard home)
the symptoms can include nausea, dizziness,
mental depression, shaking, visual
disturbances and vomiting. At extremely high
levels, loss of consciousness may occur. The
seriousness of the symptoms is dependent on
the concentration of carbon dioxide and the
length of time the individual is exposed.
CO - Denser Than Air
2
Gaseous carbon dioxide is 1.5 times denser
than air. Therefore, it will be found in greater
concentrations at low levels.
high concentrations of CO can displace
2
oxygen, and can subsequently cause death
especially if allowed to accumulate in open
pits and other areas below ground. Carbon
Dioxide acts upon our vital bodily functions in
a number of ways, including stimulating
respiration, regulation of blood circulation, and
the acidity of body fluids. Common complaints
from increases in CO levels include difficulty
2
in breathing, increase in the breathing rate
and/or pulse rate, headaches, sweating,
shortness of breath, abnormal fatigue and a
feeling of "stuffiness". Introduction of fresh air
can assist in eliminating these problems.
Finally, CO is an asphyxiate, a condition in
2
which an extreme decrease in the amount of
oxygen in the body, accompanied by an
increase of carbon dioxide, leads to loss of
consciousness or death. Concentrations of
100,000 ppm or more of CO can produce
2
unconsciousness or death
STANDARDS AND RECOMMENDATIONS
FOR CO EXPOSURE
2
The Occupational Safety and Health
Administration (OSHA) has set a standard for
the maximum allowable concentration of
carbon dioxide in the air of 0.5% (5000 ppm)
for eight continuous hours of exposure. The
maximum time weighted average exposure to
carbon dioxide in the air is set at 1.0% (10,000
PPM) for a ten hour shift in a 40 hour week.
