Notes
○ Dräger recommendations
1. These maintenance tasks may only be carried out by Dräger or trained service personnel. Details of the tests are contained in the Technical Manual
which is issued to service personnel that have attended a relevant Dräger maintenance course.
2. Replace the sintered filter if a drop in first-stage regulator performance is observed during a flow check or if it is visibly damaged.
3. Lightly lubricate the O-ring of the lung demand regulator as required (recommended lubricant is Dow Corning 111 Valve Lubricant and Sealant).
Products other than the recommended lubricant are not tested and may damage the equipment.
4. Replace the high-pressure connector O-ring if it is found to leak during functional testing or if the O-ring is visibly damaged.
5.2 Cleaning and disinfecting
!
CAUTION
Cleaning agents and disinfectants listed below are not manufactured by Dräger and have been reviewed only for compatibility when used to
clean or disinfect the subject Dräger product(s). Read and comply with all instructions for use provided by the manufacturers of such agents
and disinfectants. Dräger expressly disclaims all responsibility for any damage, personal injury or loss resulting from the use of such agents or
disinfectants.
Do not exceed 86 °F (30 °C) for washing, disinfecting and rinsing solutions. Do not exceed 140 °F (60 °C) for drying, and remove components
from the drying facility immediately when dry. Drying time in a heated dryer must not exceed 30 minutes.
Do not immerse pneumatic or electronic components in cleaning solutions or water.
If water is trapped and then freezes inside the pneumatic system of the breathing apparatus (such as the lung demand regulator) its operation will
be impaired. Prevent any liquid from entering, and thoroughly dry the breathing apparatus after cleaning to prevent this from occurring.
Refer also to the Instructions for Use for the lung demand regulator, face mask and other associated equipment.
5.2.1 Manual cleaning of the breathing apparatus (USA)
Cleaning and disinfecting materials:
● Cleaning agent – 1008 Green Liquid Hand Dish Wash
● Disinfecting agent – 800 Spur-Tex Disinfectant Cleaner-Deodorant
(concentration: 1.6 % (2 fl oz per gallon))
● Use only clean lint-free cloths.
1. Prepare cleaning solution as per manufacturer’s instructions. Clean
the breathing apparatus manually using a cloth moistened with
cleaning solution to remove excess dirt.
2. Prepare disinfecting solution as per manufacturer’s instructions. Apply
to all internal and external surfaces, ensuring that all surfaces remain
visibly wet for 15 minutes.
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. Contact service personnel or Dräger if disassembly of pneumatic or
electronic components is required.
5.2.2 Manual cleaning of the breathing apparatus (Canada)
Cleaning and disinfecting materials:
● Cleaning agent – mild soap solution
● Disinfecting agent – Neutral Disinfectant Cleaner (concentration: 0.5 %
(0.5 fl oz per gallon or 15 ml per 3.785 liters))
● Use only clean lint-free cloths.
1. Prepare cleaning solution as per manufacturer’s instructions. Clean
the breathing apparatus manually using a cloth moistened with
cleaning solution to remove excess dirt.
2. Prepare disinfecting solution as per manufacturer’s instructions. Apply
to all internal and external surfaces, ensuring that all surfaces remain
visibly wet for 10 minutes.
3. Rinse all components thoroughly with clean water to remove all
cleaning and disinfecting agents.

5.2.3 Carrying harness – Thorough cleaning
!
CAUTION
Thorough cleaning may only be carried out by suitably trained
personnel. Disassembly of the breathing apparatus by untrained
personnel is not permitted and may damage the apparatus.
1. Remove the harness from the carrying system and clean using one of
the following methods:
a. Clean manually in a bath containing recommended cleaning or
disinfecting agents.
b. Machine wash (at 86 °F (30 °C)) using a proprietary brand washing
solution (do not use biological washing powder).
2. Rinse the harness thoroughly with clean water to remove all cleaning
and disinfecting agents.
3. Dry all components including internal parts.
5.3 Maintenance work
5.3.1 Air cylinder charging
!
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.
Refer to the instructions supplied with the cylinder and the charging
apparatus for recharging a compressed-air cylinder.

Storage
6.1 Storage preparation
● Extend the shoulder straps, 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 rubber 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 3.5.3).
6.2 Storage conditions
● Store the equipment between 5 and 77 °F (-15 and +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.
7
Disposal
Dispose of used batteries in accordance with national or local regulations.
When required, dispose of other parts of the breathing apparatus,
including electrical and electronic equipment, in line with any national or
local environmental regulations.
