Place the On / Standby switch in the STANDBY (Off) position. Disconnect the corrugated rubber tubing
from the Rubber Goods and breathe into the corrugated tubing connected to the bag tee. You should not
be able to fill the bag with exhalation gas. If the bag fills, the system’s Non-Rebreathing Valve (See Fig.
10 below) is not functioning properly and should be replaced.

from the gas scavenging apparatus and draw air with your mouth through the corrugated tubing
connected to the bag tee. With gas bag fully collapsed, you should be able to draw ambient air through
