5. Place the exhalation box onto the inhalation box such
that the two hose attachments are 120° apart. while hold-

Moupiece/hose Reassembly
1. Insert non return valve (7) into the inlet connector (5).
Press firmly on the center of the check valve so the barb
goes through the hole. Look into the connector to ensure the
barb is all the way through and the check valve is secure.
Place a new, lubricated o-ring (6) on the connector.
2. examining the valve support (9), you will notice that one
side is flat, the other side is slightly concave. Insert the other
non return valve into the valve support so the valve sits
against the concave side. firmly press on the center of the
valve until the barb is all the way through the hole. visually
inspect the barb to make sure it is completely through the
hole.
3. Install a new, lubricated o-ring (10) onto the valve support.
with the non return valve facing inward, insert the valve
support into the outlet connector (11). Install a new,
lubricated o-ring (6) onto the outlet connector.
4. Pass the connector ring (4), threaded side first, over the
open end of the inlet connector. Insert the inlet connector into
the wide end of one of the rubber corrugated hoses (18) as
far as it will go. Repeat this step for the other connector.
5. Place the small hex nut (2) into the hex shaped hole on
the hose clamp (3). wrap the clamp around the rubber hose
and pull it together using the clamp installation tool
(PN 7-0543) as shown in the picture. Note: This tool is not
required, but it makes the job much easier. Insert the screw
(1) and tighten with a medium blade screwdriver. Repeat this
step for the other hose.
