GENERAL INFORMATION
General notes
These operating instructions enable you to use the
airLPT216 air leak proof tester safely and reliably.
Read through these operating instructions and keep
them in a safe place.
Intended use
The airLPT216 air leak proof tester may only be used
by competent personnel and only for its intended
use. It has been design for air leakage testing of air
duct systems, especially in HVAC systems, and its in-
tended use is as a measuring device.
It is used to determine the quantity of air leaked and
the air tightness class achieved in HVAC systems ac-
cording to EN 13779, or EN 1507 and EN 12237. Due
to the automatic determination of the air tightness
class there are a wide range of applications from very
small systems (7 m
2
surface area) through to large
systems.
In addition to the measuring function, the measuring
device can also pressurise the connected system to
test pressure (positive pressure) for a defined time.
This function is intended for leakage detection. Con-
tinuous leakage detection may only be carried out in
Leak Detection mode.
The airLPT216 air leak proof tester may only be used
for the applications described above.
The user must prevent any use that is not intended
use. The test lines may only be pressurised with the
maximum positive or negative pressure for which
they have been designed. The airLPT216 air leak proof
tester is explicitly not intended for performing test
tasks in which the connected test object is expected
to be destroyed due to positive or negative pressu-
res.
Before performing the test, the mechanical strength
of the system to be tested must be checked. In par-
ticular, system parts that are not fixed or are partly
fixed, e.g. an unriveted end cover, can come off sud-
denly during the test sequence and can cause seri-
ous injuries, consequential damage and damage to
the airLPT216 air leak proof tester.
The device should be transported, stored and used in
a dust-free and dry environment. Avoid getting dirt
(e.g. dust, moisture) on the connections for the air
and pressure measuring hose.
In case of positive pressures higher than 2,000 Pa,
the two measurement connections - air connection,
pressure measurement connection - must be addi-
tionally secured against coming off suddenly at the
measurement openings.
