WARNING !
Each time you connect a machine to a wall or
ceiling gas outlet carefully check hoses to
ensure that both ends of the hose are indexed
for the same gas. Pipeline delivery hoses used
between wall outlets and anesthesia
machines have caused accidents when,
during assembly, an oxygen fitting was placed
on one end of the hose and a nitrous oxide
fitting on the other end.
WARNING !
Always use medical grade gases that are dry
and free from dust and oil. Contaminated gas
may cause system malfunction.
