Tightness Test of the Protective Suit
To inflate the protective suit, use only compressed
air that is clean and free from oil.
•
Inflate suit to 16 mbar.
•
Stabilizing time 3 min.
•
Reduce pressure to 18 mbar (test pressure).
•
Maximum permissible pressure drop in 3 min
2 mbar.
At the end of the test, reassemble the valve discs
and valve covers.
Valve tightness test see section 6.1.
Note:
In order to avoid erroneous readings, the test
should be conducted in a room free of draft.
5.5
Checks in Case of Leaks
•
Are the test connections tight?
•
Is the zipper completely closed?
•
Are the valve seat (10) and the connection to the
threaded ring (8) with the slide ring (9) assembled
correctly? (Fig. 1).
5.6 Visual
Checks
Visual slight abrasions as well as slight discolora-
tions on the outside of the suit do not reduce its pro-
tective performance against chemicals.
The emergence of age resistors during storage does
not reduce the quality of the boots.

Maintenance Work
6.1
Suit Valves
After each repair or cleaning a tightness test of the
suit valves is to be done with the mask tightness te-
ster in combination with valve test adapter and com-
pensation container:
•
create a negative pressure of 10 mbar
•
max. pressure change within one minute must
not exceed 1,0 mbar
In case of a leak either the valve disc or the entire
valve assembly must be replaced. To do this, the
threaded ring is unscrewed from the inside of the suit
using the key (see Ordering Information). Regard-
less of the above measures, it is recommended to
replace the valve discs every 2 years at the latest
(Fig. 1).
6.2
Zipper
After each cleaning or disinfection the zipper is
treated with the grease pencil or zipper spray in such
a way that only a thin lubricant film covers the metal
links. See following figure for area to be lubricated:
6.3
Replacing the Lens
Replacing the lens (only chemical protective suit
VAUTEX S Type 1a and chemical protective suit
