Reverse Flow Check
1. Connect both gas supply hoses to the inlet connectors.
2. Connect the oxygen hose to an oxygen pressure regulator, and
submerge the free end of the air hose in a container of water.
Do not make a connection to either outlet (so that they remain
closed).
3. Slowly adjust the oxygen pressure regulator to increase pressure
from 0 to 50 PSIG* while looking for bubbles to rise from the
submerged air hose connector.
The presence of bubbles indicates leakage of the one-way valve
and the need for repair.
4. If there is no leakage, disconnect the oxygen from the regulator
and submerge the end of the hose in water.
5. Connect the air hose to an air pressure regulator and repeat the
procedure. Repair if bubbles are present.
*Gas supply pressures of 50 PSIG provide optimal performance.
