12. Slowly open the cylinder valve at least two turns.
The Connect ECU automatically switches to On mode.
An acoustic signal sounds.
The battery status is shown on the display.
The Connect ECU queries whether to carry out the high-
pressure leak test. If the test is to be carried out, the
symbol and the current pressure are displayed. A high-
pressure leak test can only be carried out if the cylinder
pressure is at least 150 bar.
If, for example, the closed-circuit breathing apparatus is
to be worn in a chemical protective suit, the acoustic
signals can be set to a low volume. To do so, confirm the
query.
13. Close the cylinder valve.
The test is carried out automatically.
The result of the test is shown after approx. 15 seconds.
The or symbol is displayed. If is displayed, the
closed-circuit breathing apparatus must not be used.
If the test was successful, the display shows the current
pressure of the compressed oxygen cylinder.
14. Completely open the cylinder valve.
15. Use the display on the Connect ECU to check that there is
adequate oxygen in the cylinder for the period of use.
16. Remove the protective cap from the connecting piece on
the closed-circuit breathing apparatus.
17. Inhale, hold your breath and insert the connecting piece
on the closed-circuit breathing apparatus into the
connecting piece on the full face mask. A click can be
heard when the connecting piece engages.
18. Continue breathing as normal.
19. Firmly squeeze the inhalation hose and breathe in until
there is negative pressure in the mask. Do not breathe in
for approx. 10 seconds. The negative pressure must
remain unchanged, otherwise tighten the harness of the
full face mask.
20. Continue as follows:
If the closed-circuit breathing apparatus is OK:
● The blue LEDs of the Connect ECU and the buddy-
light pulse blue. The cylinder pressure is displayed on
the Connect ECU. Additional information is displayed
depending on the setting. The apparatus can now be
used.
If an error was detected:
● An acoustic and optical warning is emitted on the
Connect ECU. The closed-circuit breathing apparatus
must not be used.
4.3.4 Activating the automatic distress signal
function
● Remove the function key from the Connect ECU.
This activates the motion sensor.
The symbol is displayed.
4.4 During use
4.4.1 General information
– The chemical process during CO
2
absorption creates heat
and moisture. This is a normal process that does not
impair the functional integrity of the closed-circuit
breathing apparatus.
– The closed-circuit breathing apparatus continues to supply
breathing air even if the electronics fail. In this case, the
user should retreat immediately.
4.4.2 In an emergency
– To request help, press the alarm button on the
Connect ECU. The main alarm sounds, the symbol is
displayed and the red and blue LEDs flash.
WARNING
Danger to life!
If there are any faults on the closed-circuit breathing
apparatus, the protection provided by the apparatus may
be reduced.
► In the event of faults on the closed-circuit breathing
apparatus, retreat immediately!
– In the event of a malfunction of the automatic oxygen
supply (failure of minimum valve and/or constant dosage),
briefly press the red bypass button. Additional oxygen is
supplied to the breathing circuit.
4.4.3 Acknowledging the alarm
● To acknowledge the main alarm, either insert the function
key into the Connect ECU or press and hold the right and
left button on the Connect ECU for approx. 3 seconds.
4.5 After use
1. Unplug the connecting piece from the full face mask:
Press the button on the full face mask and simultaneously
remove the connecting piece from the full face mask.
2. Close the cylinder valve immediately after pulling out the
connecting piece. The air is automatically released from
the breathing circuit.
3. Place the protective cap on the connecting piece of the
closed-circuit breathing apparatus.
4. Remove the full face mask.
5. Turn off the Connect ECU: If the pressure in the closed-
circuit breathing apparatus is 0 bar, press and hold the
right and left button for 3 seconds. The display first shows
3 - 2 - 1, then the battery status.
6. Take off the closed-circuit breathing apparatus:
a. Open the quick-release buckles of the waist belt and
chest strap.
b. Loosen the shoulder straps.
c. Lift the closed-circuit breathing apparatus over your
head and away from your body. Place the closed-
circuit breathing apparatus upright on the ground. Do
not drop the apparatus!
7. Have the closed-circuit breathing apparatus serviced.
