1. foreword
This operating manual describes the operati-
on of the Labtec ECO series of test instru-
ments.
Labtec test devices are professional tools
that require comprehensive respiratory pro-
tection expertise, e.g. by completing training
as a respirator maintenance technician, to
ensure proper operation and correct measu-
rement.
A prerequisite for proper operation of the de-
vice is that the device is operated and used
exclusively in accordance with these opera-
ting instructions. Labtec is not liable for per-
sonal injury or damage to property or conse-
quential damage of any kind if the device is
used in a manner other than that described
in this manual. The same applies to the ac-
ceptance of any warranty and guarantee
claims.
Otherwise, the terms of sale and delivery as
well as the warranty and guarantee conditi-
ons of Labtec GmbH apply, which are not
extended in any way by these instructions.
2. safety instructions
Each Labtec test device requires device-
specific instruction by an authorized Labtec
employee or training partner.
The device may only be operated by instruc-
ted and authorized personnel.
The device may only be serviced and re-
paired by trained and certified Labtec service
technicians. Only original spare parts and
accessories must be used.
The device may only be opened by a Labtec
service technician or, if expressly requested,
under instruction by a Labtec employee.
To ensure proper functioning of the device
and thus a correct measurement result, the
device must be serviced at least once a year
by a trained and certified Labtec service
technician and tested and calibrated by him
or her using a Labtec calibration device.
The list of current, certified employees, trai-
ning partners and service technicians is up-
dated daily and is available from Labtec or
on the Labtec homepage.
Labtec devices are partly operated with bre-
athing air in the high pressure range of up to
400bar. Operating a device under high pres-
sure requires the greatest care. Before
connecting and disconnecting a test item /
breathing apparatus, the test bench must al-
ways be completely depressurized and air
supply lines, especially the main valve,
closed.
The device connection must always be che-
cked. Devices must always be connected
completely correctly. When connecting to the
high pressure device connection, the device
thread must be completely screwed to the
internal thread of the device connection.
Before switching off the test device electri-
cally, the test bench must first be completely
depressurized and vented and then all
connected devices and any full face masks
must be removed.
Never test dirty demand valves or masks on
the test head. There is a risk of dust particles
getting into the measuring system, which
can impair the function.
When the test stand is started up, the mouth
opening and the instrument connections
must remain open, otherwise self-calibration
will be incorrect and the measurement data
will be incorrect.
The test device must be set up horizontally
and rest well on all support buffers.
Care must be taken to ensure that the mea-
suring nozzle in the mouth opening in the
test head is not clogged. In case of false
measuring values in low pressure, the ope-
ning can be cleaned with a 0.2 - 0.35 mm
needle.
In case of queries or uncertainties
contact the Labtec customer service!

3. device description
Labtec ECO dynamic and Labtec ECO
static are electronic test devices to be ope-
rated via a PC for the testing of breathing
masks according to DIN EN 136, self-
contained breathing apparatus (SCBA) ac-
cording to DIN EN 137 and chemical protec-
tive suits (CPS) according to DIN EN 943-1.
The tests are performed in the low (-50 to 50
mbar), medium (0 to 20 bar) and high pres-
sure measuring range (0 to 300 bar).
For testing other breathing apparatus or che-
mical protective suits, contact Labtec. Only
breathing air according to DIN EN 12021
may be used.
Model differences
Labtec ECO dynamic are automatic testing
devices incl. artificial lung for dynamic tes-
ting of breathing equipment during respirati-
on.
Compared to Labtec ECO dynamic, Labtec
ECO static test devices have no artificial
lung and are therefore only suitable for static
testing of breathing equipment.
The device has several expansion options
(modules) which are identified by a letter
code:
Modul T (Terminal): Control panel with
OLED display and complete set of control
elements for manual operation of the unit.
Module COM (All-in-One Computer):
Freely positionable touchscreen PC, connec-
ted to test device via swivel arm mounting,
incl. pre-installed LabNet Profi test software.
Module S (safety valve test): System com-
ponent and module for automatic medium
pressure increase for SCBA safety valve
tests.
Connection requirements
A 230-240 V / 50-60 Hz power supply is re-
quired to operate the test stand.
The high pressure supply required for opera-
tion is provided by a 300 or 200 bar brea-
thing air cylinder or by a central air supply
with 300 bar.
As medium pressure connection Euro-
coupling and nipple are available as stan-
dard. If units with other coupling connections
are tested, appropriate intermediate adap-
ters must be used. Please contact the manu-
facturer of the units for this.
Scope of delivery and accessories
The scope of delivery of the device includes
a high-power-connection cable incl. screw
fitting, power supply cable and a USB cable.
Adapters for the connection of CPS, regula-
tors and sealing caps for respirators must be
ordered separately depending on the
connection used (e.g. ESA, PE45, RD40,
manufacturer-specific connections).
Labtec offers a wide range of accessories for
test devices.
The range includes test adapters for adap-
ting all respiratory protection devices on the
market, quick release devices for quick de-
vice adaptation as well as holders for holding
helmet-mask combinations.

Device connection (breathing mask)
The test head must be completely vented. The
breathing connection of the mask is closed
with a suitable sealing cap. Alternatively,
connect the mask to a suitable demand valve
and then make a device connection (SCBA).
The mask is put on the test head. The inner
mask should rest correctly on the nose of the
probe.
Then tighten the fasteners of the head mask
starting from the bottom. The test head can
now be inflated until a tight fit of the mask is
ensured. If necessary, readjust the mask.
Device connection (SCBA)
The regulator of the compressed air breathing
apparatus is screwed directly to the high pres-
sure device connection. When connecting,
make sure that the compressed air breathing
apparatus is screwed completely into the inter-
nal thread of the device connection.
For tests in the medium pressure range, dis-
connect the medium pressure line of the
SCBA at the Euro coupling and connect it to
the plug nipple of the medium pressure device
connection and the line of the demand valve to
the EURO quick coupling of the medium pres-
sure device connection.
If the SCBA to be tested does not have a Euro
coupling, a suitable adapter must be used.
Please contact the compressed air breathing
apparatus manufacturer.
The demand valve is inserted into the mouth
opening of the test head using a suitable
adapter.
8. care and maintenance
The test instrument should be protected from
external harmful influences such as water, mo-
isture in the form of steam and dust.
The test head should be cleaned and maintai-
ned regularly. This can significantly increase
the service life of the search unit.
The test head should always be covered with
the enclosed protective hood after the instru-
ment has been used.
> See separate test head care instructions
The test device must be serviced at least an-
nually by a certified Labtec service technician.
The test device is recalibrated and deviations
in the previous test cycle can be excluded.
The maintenance is carried out with a special
calibration device.
The maintenance is confirmed by a calibration
certificate issued directly by Labtec. The main-
tenance may only be carried out by authorized
and trained service technicians.
In order to ensure a cost-effective and timely
maintenance, it is possible to conclude a main-
tenance contract with Labtec.
