6.2 Cleaning and disinfecting
CAUTION
Trapped water and ice inside the pneumatic system (such as the lung
demand valve) may impair the operation of the breathing apparatus.
► Prevent any liquid from entering the pneumatic system, and
thoroughly dry the breathing apparatus after cleaning and disinfecting.
NOTICE
Cleaning agents and disinfectants listed in this section are not
manufactured by Dräger and have been reviewed only for compatibility
when used to clean or disinfect the subject Dräger products.

WARNING
Air quality for compressed air cylinders must conform to the minimum
grade requirements for Type 1 gaseous air as defined in the CGA
Commodity Specification for Air, G-7.1 (Grade D or higher quality) and,
where appropriate, be in accordance with: NFPA 1989 Standard on
Breathing Air Quality for Emergency Services Respiratory Protection.
► Ensure that the air supply meets these requirements.
Refer to the instructions supplied with the cylinder and the charging
apparatus for recharging a compressed air cylinder.
7 Transport
Transport the product in its original packaging.
8 Storage
8.1 Storage preparation
● Extend the shoulder harness, waist belt, and the straps of the face
mask.
● For storage, place the face mask in a protective bag (contact Dräger
for supply of a suitable bag).
● Route pneumatic hoses in such a way that the bend radius is not too
acute and the hose is not stretched, compressed, or twisted.
● With the system switched off, a small amount of battery power is
consumed. If the system is not to be used for a long period, remove the
batteries (see Section 4.6.3).
8.2 Storage conditions
● Store the equipment between 5 °F to 77 °F (-15 °C to +25 °C). Ensure
that the environment is dry, free from dust and dirt, and does not
subject the equipment to wear or damage due to abrasion. Do not
store the equipment in direct sunlight.
● Fix the breathing apparatus securely to any raised mounting point to
prevent it from falling.
● If storing the equipment in a vehicle, ensure that the breathing
apparatus is securely retained and does not interfere with the
operation of the vehicle.
