down again. The Connect ECU is then in Standby mode
and the test can be repeated.
4. Set the selector switch on the test unit to L/min .

5.2.7.2 Emptying the refill absorber
WARNING
Risk of chemical burns!
The CO
2
absorber may contain alkaline liquid which may leak
out during disassembly and cause chemical burns!
► Avoid skin contact. Use protective gloves and goggles. In
case of eye contact, rinse straight away with plenty of
water and seek medical attention immediately.
1. Open the lid of the refill absorber (see "Lids of the
regeneration cooler and CO
2
absorber", page 15).
2. Check the sealing in the lid. If the sealing is excessively
contaminated or faulty, pull the sealing frame out of the lid
and remove the sealing from the sealing frame.
3. Remove the sieve with marking II.
4. Remove and dispose of the soda lime and filter mats.
5. Remove the sieve with marking I.
6. Clean and disinfect all parts of the refill absorber.
5.2.7.3 Filling the refill absorber
Only fill the refill absorber with Drägersorb 400. Pay attention
to the safety data sheet on Drägersorb 400 when handling the
CO
2
absorber!
WARNING
Reduced period of use possible!
If the expiration date of the soda lime is exceeded, the
intended period of use for the apparatus may not be reached.
► Note the expiration date on the storage container. Only
use soda lime that has an adequate life span for the
planned use and any storage period!
CAUTION
Health risk!
Direct contact with soda lime irritates eyes, mucous
membranes, and skin!
► Avoid skin contact. Use protective gloves and goggles. Do
not inhale released soda lime dust. Use dust mask with P2
or R95 filter. In case of skin or eye contact, wash off soda
lime dust immediately.
WARNING
Higher CO
2
content possible in the inhaled air!
If the soda lime is only used as a loose fill, the capacity may
not be enough for the planned period of use.
► Fill refill absorbers so that no rattling noises are heard.
1. Open the lid (1) of the refill absorber (see "Lids of the
regeneration cooler and CO
2
absorber", page 15).
2. Place the sieve with the marking I (4) in the refill absorber
(5) as shown below.
3. Insert a filter mat (3) in the refill absorber. (There is no
preferred orientation for the filter mat.)
4. Half fill the refill absorber with Drägersorb 400. Compact
the soda lime by using your hand to gently strike the side
of the housing. Steadily fill the refill absorber up to the
filling mark (6, marker between the transparent and non-
transparent part of the container) and compact the soda
lime. Alternately fill and compact until the soda lime does
not settle any further. The surface of the soda lime must
be smooth.
5. Insert a filter mat (3) in the refill absorber. (There is no
preferred orientation for the filter mat.)
6. Place the sieve with the marking II (2) in the refill absorber
as shown below.
7. Only if the sealing has been removed:
a. Place the sealing in the lid.
b. Fasten the sealing with the sealing frame.
8. Close the lid (1) (see "Lids of the regeneration cooler and
CO
2
absorber", page 15).
9. Check whether rattling noises are heard when shaking the
refill absorber. If rattling noises are heard, the refill
