Breathing Apparatus

MSA recommendation:
1. Before connecting the unit to the medium pressure, switch off the lung governed demand valve by pressing the
red control button to prevent unintentional air supply (refer to the operating manual of the lung governed
demand valve).
2. Open cylinder valve of the mounted compressed air cylinder fully.
a. Close the warning signal with a protective cap (10190947-SP).
b. Close the AE / ESA lung governed demand valve with the washing adapter (10200072), the AS lung
governed demand valve with the washing adapter (10200071) and switch it on ("ON") to produce a
continuous air flow of approx. 5 l/min.
3. Remove rough dirt from breathing apparatus with water hose before placing the device in the machine (see
chapter 2.3 ).
4. Start the washing procedure.
MSA recommendation for pre-cleaning:
○ Use EW80 clean as cleaning detergent with a concentration of 1% (see
○ Temperature: 45 °C + 5 °C.
○ Washing is depending on the machine type and the degree of soiling (see
5. After washing, close the cylinder valve(s) of the assembled breathing air cylinder(s) completely. Vent air from
the device with the lung governed demand valve and remove the protective caps and wash adapter.
For complete and secure drying proceed according to the specification in chapter
If the cleaning is not successful, restart the entire process. For a better result the breathing apparatus can be
disassembled as follows before restarting:
1. Remove compressed air cylinder.
2. Disconnect lung governed demand valve.
3. Separate cylinder cover from cylinder .
4. Remove harness parts from the slots of the backplate.
5. Harness assembly and cylinder cover can be cleaned in a washing extractor at 45 °C + 5 °C with the same
cleaning agents.
MSA recommendation:
The use of padded washing nets is a basic requirement for the safe care and decontamination of the harness
and belts. These nets must have a multi-layer construction to prevent metal applications from hitting the inner
drum. Firefighting suits of similar construction, for example, can be used as filling material in the drum.
NOTE: Do not submerge the pressure reducer in water without the above mentioned protective cap.
Pressurize the pressure reducer and seal the warning signal.
For complete and secure drying proceed according to the specification in chapter
