Connecting/Disconnecting Cylinder to/from Compressor

Connecting the Cylinder to the Compressor

DO NOT modify any connections on the HomeFill compressor.
NEVER use tools of any kind to connect/disconnect the cylinder and the
compressor. Otherwise, severe injury and/or damage may occur.
DO NOT drop oxygen cylinders. Use two hands when handling/transporting oxygen
cylinders. Otherwise, injury or damage may occur.
DO NOT use a liquid leak detector to test for leaks.
NOTE: For this procedure, refer to FIGURE 4.1 on page 20 and FIGURE 4.2 on page 21.
1. Prior to each use, inspect product for visible damage. Refer to External Examination
on page 19. DO NOT use if any damage is found.
NOTE: If for any reason, any label becomes illegible or lost, contact your dealer/Home Care
equipment provider.
2. Examine the cylinder gauge. If the cylinder pressure is less than 1500 psig. (10342 kPa),
proceed to STEP 2.
NOTE: For location of the cylinder gauge, refer to the cylinder user manual. If the cylinder
pressure is greater than 1500 psig (10342 kPa), DO NOT attempt to top off the cylinder. It may
not fill. Bleed the cylinder or select another cylinder.
3. Set the regulator flow dial on the cylinder to Off (Detail "B" of FIGURE 4.2). Refer to
the cylinder user manual.
4. Remove the cylinder and connector fillport covers (if present).
NOTE: On older models, the green dots do not exist.
5. To reset the connector, momentarily push down on the outer ring (sleeve) of the
connector fillport until GREEN dots are visible (FIGURE 4.1).
NOTE: If the outer ring (sleeve) is in the up position (GREEN dots not visible), the connector
fillport will not be able to accept the cylinder fillport. Pushing down momentarily will reset the
connector fillport (GREEN dots visible) to accept the cylinder fillport.
