disinfecting solutions or water.
For information about suitable cleaning and disinfecting agents
and their specifications refer to document 9100081 at
www.draeger.com/IFU.
6.2.1 Cleaning and disinfecting the breathing apparatus
Clean the breathing apparatus if it is dirty. If the equipment has been
exposed to contaminants, disinfect any components that come into direct
and prolonged contact with the skin.
Refer also to the instructions for use for the lung demand valve, mask, and
other associated equipment. Contact service personnel or Dräger if
disassembly of pneumatic or electronic components is required.
Work equipment
– Use only clean lint-free cloths
1. Clean the breathing apparatus manually using a cloth moistened with
cleaning solution to remove excess dirt. Remove and clean the
following:
– The protective covers (see section 6.3.3). Clean the protective
covers and the LCD screen and LED panel.
– The power pack (see section 4.5.6.2). Clean the power pack and
compartment, and ensure that the contacts and locking
mechanism are clean, dry and undamaged.
2. Apply disinfecting solution to all internal and external surfaces.
3. Rinse all components thoroughly with clean water to remove all
cleaning and disinfecting agents.
4. Dry all components using a dry cloth, in a heated dryer, or in air.
5. Carry out a full electronic monitoring system functional test (see
section 6.3.4.1).
6.3 Maintenance tasks
6.3.1 Visual inspection
A visual inspection must fully check the product including all component
parts and accessories.
1. Check that the product is clean and undamaged, paying particular
attention to pneumatic system components, connectors, and
elastomeric components such as hoses.
– Typical signs of damage that can affect the operation of the
product include impact, abrasion, cutting, corrosion, and
discoloration.
2. Report damage to service personnel or Dräger, and do not use the
product until faults are rectified.
6.3.2 Checking the medium-pressure quick coupling
This task applies only to breathing apparatus with a removable lung
demand valve. If there is any difficultly disconnecting or connecting, see
the troubleshooting information in section 5.
1. Press the male element into the female element of the coupling until
an audible click is heard.
2. Disconnect the male element from the female element of the quick
coupling.
3. Reconnect the quick coupling as per step 1.
