Maintenance
Replacing the
Absorbent
This section outlines procedures for maintaining and cleaning the
Narkomed 2B.
Routine maintenance must be performed regularly to ensure safe and
effective operation. Regularly check the condition of the absorbent and
the overall condition of the machine, power cord, hoses, and breathing
bag.
When the carbon dioxide absorbent in the absorber system is exhausted,
it must be replaced. Refer to the manufacturer's instructions for the
signs to expect when the absorbent is exhausted.
If the machine has been out of use or in storage, replace the absorbent
before using the machine. North American Dräger recommends
establishing a routine schedule with a sufficient safety margin for
replacing absorbent.
When using loose absorbent, do not fill above the maximum fill level line
located about a quarter-inch from the top of the canister. The clearance
and the ratio of canister diameter to screen opening minimize the
potential for channeling. In channeling, gas flows through the canister
along the path of least resistance. The gas depletes the efficiency of the
absorbent along this route, bypassing absorbent in the other areas of the
absorber.
WARNING: Absorbent is caustic and is a strong irritant to the eyes,
skin, and respiratory tract. When replacing the absorbent,
take care not to spill its caustic contents.
To replace the absorbent:
1. Pull the canister release lever down.
2. Remove the canisters from the absorber system.
3. Empty the contents of the canisters into an appropriate refuse
container.
4. Check the canisters to make sure they are not chipped or cracked.
