With a pair of needlenose, carefully remove both mushroom carriers from each end of the Outer Housing. (They will pull directly outwards)
Inspect (127 )-Rings) and Mushroom Valve for possible damage.
When installing the mushroom valves, the left hand side must allow the gas to flow inwards,
from the breathing loop. This is the gas you will be inhaling, and is the scrubbed
gas.
The right hand side must allow the gas to flow outwards. This is the gas that you have
exhaled, and will be going into the unit to be scrubbed. |

Using an 1/8 inch Allen wrench, reach through the breathing port and remove the screw that holds the lever in place.
