Connection Of Co 2 Gas Cylinder - Sanyo MCO-18AIC Service Manual

BEFORE COMMENCING OPERATION
Connection of CO gas cylinder

WARNING
Check the gas type and ensure that it is fit for the purpose. Make sure that all pipes are
connected correctly and are not liable to become disconnected. Ensure that the gas pressure is
set at the specified value. Improper connection of the gas pipe or use of incorrect gas pressure
may result in leakage of CO gas. Elevated level of CO gas can be hazardous to health and may
2 2
lead to asphyxiation and risk of death.
Use a liquefied CO gas cylinder, not a siphon (dip tube) type. The CO gas should be 99.5% or more
2 2
pure.
1. Install a pressure regulator (optional accessory MCO-100L) on the cylinder. Use a regulator rated at
2 2
25MPaG (250kgf/cm G, 3600psiG) on the primary side and 0.2MPaG (2.0kgf/cm G, 30psiG) on the
secondary side.
2. Using the gas supply pipe provided, connect the pressure regulator to the CO inlet located at the rear
2
left hand side of the CO incubator.

3. Set the CO pressure on the secondary side to 0.03MPaG (0.3kgf/cm G, 4.3psiG) (at gas injection).
2
Excessive pressure may cause disconnection of internal pipes inside the CO incubator which will result
2
in leakage of CO gas into the atmosphere. Elevated level of CO gas can be hazardous to health
2 2
and may lead to asphyxiation and risk of death. The repair of the incubator will be necessary if the
internal pipe is disconnected.
4. Check that no gas is leaking at any point where the pipe connects with the CO regulator or the CO
2 2
incubator.
Note:
• Refer to "Procedure for replacement of gas cylinder" enclosed with the unit at the time of replacement.
• The incubator, including the gas supply pipes and services must be examined at frequent intervals to
ensure they are safe. Ensure that items such as pipes are replaced if there is any sign of deterioration.
