Bellows Assembly
NOTE
：
Before installing the bellows housing,
check that the sealing component on the
breathing system is in position. If not,
you must install the sealing component
properly before installing the bellows
housing.
When installing the bellows housing,
align the bellows housing bayonet
tabs with the slots on the breathing
system and then lower the bellows
housing. Make sure that the housing
is depressing the seal evenly. Hold
the bellows housing tightly and turn it
clockwise until it stops. Make sure that
the side of the housing marked with
scale is facing the operator.
Incorrect installation causes the folding
as shown in the fi gure, which leads to the
breathing system leakage. Reinstall the
bellows housing.
