5.2.4.2  Ice cooler cover

The ice cooler cover is hooked into the lower part. The cover 

can be unhooked for cleaning and disinfection. To do so, open 

the cover wide until the locking device on the pin can slide 

through the groove in the hole.

5.2.4.3  Cleaning the closed-circuit breathing apparatus

1. Prepare a cleaning solution comprised of water and a 

cleaning agent.

2. Clean all parts that conduct the breathing air, the waist belt 

and the harness with a soft cloth and a cleaning solution.

The carrying frame and lid can be brushed off with a soft 

brush and cleaning solution if necessary.

Wipe down the Connect ECU with a soft cloth. The rubber 

protection and the protective covers can be removed for 

cleaning if necessary.

3. Rinse all parts thoroughly under running water.
4. Prepare a disinfection bath comprised of water and a 

disinfectant.

5. Place all parts that conduct breathing air into the 

disinfection bath. Only disinfect the waist belt and harness 

if necessary.

6. Rinse all parts thoroughly under running water.
7. Allow all parts to dry (max. temperature: 60 °C). Keep 

away from direct sunlight.

Dräger recommends using both a drying cabinet and a 

hose drying unit for drying. 

If hot air is conducted through the regeneration cooler, it is 

dry after approx. 4 hours and can subsequently be 

regenerated. If the regeneration cooler is dried in room air 

without air circulation, drying takes longer. 

8. Store regeneration coolers at temperatures below 25 °C to 

allow the latent heat storage medium to regenerate.

All components of the closed-circuit breathing 

apparatus must be completely dry before storage to 

prevent mould formation.

5.2.5  Assembling the closed-circuit breathing 

apparatus

5.2.5.1 Overview

1. Install the CO

2

 absorber (see "Installing the CO

2

absorber", page 19).

2. Install the breathing air cooler (see "Installing the 

breathing air cooler", page 20).

3. Fit the connecting piece (see "Fitting the connecting 

piece", page 20).

4. Fit the valves to the breathing bag (see "Fitting the 

drainage valve and relief valve", page 21).

5. Install the breathing bag (see "Fitting the drainage valve 

and relief valve", page 21).

6. Install the compressed oxygen cylinder (see "Fitting the 

compressed oxygen cylinder", page 21).

7. Close the closed-circuit breathing apparatus (see "Closing 

the closed-circuit breathing apparatus", page 22).

8. Fit the waist belt and shoulder straps (see "Fitting the 

waist belt and shoulder straps", page 22).

5.2.5.2  Prerequisites for assembly

The following components must be prepared for assembly:
– If a regeneration cooler is to be used: The regenerated 

cooling elements are available.

– The compressed oxygen cylinder is full.
– The refill absorber is full.

For hygiene reasons, the apparatus should be fitted in a 

clean work environment and with clean hands. Wear gloves if 

necessary so that the cleaned and disinfected components 

are not re-contaminated.

5.2.5.3 Installing the CO

2

 absorber

WARNING

Reduced period of use possible!

If the soda lime comes into contact with ambient air or is too 

old, the period of use intended for the apparatus may not be 

possible.

►

Only install a CO

2

 absorber that meets the criteria 

described in chapter 4.1.3.

1. Unpack the CO

2

 absorber if necessary. Fit the lid on a 

disposable absorber.

2. Fasten the breathing hose on the CO

2

 absorber (see 

"Breathing hoses", page 14).

3. Place the CO

2

 absorber in the mounts on the carrying 

frame. A clicking sound can be heard when the CO

2

absorber engages in the locking mechanism.

4. Connect the blue medium-pressure hoses to the CO

2

absorber.
