Air leakproof tester (airLeakProofTester 216)
airLPT216
Version 1.2 Dated 07 March 2017
An air leakage test on air conditioning systems is
necessary to check for compliance with the required
air tightness class and thus the airtightness of the
ductwork system. The relevant standard on which
ventilation and air conditioning systems are based
is EN 13779 “Ventilation for non-residential buildings
– Performance requirements for ventilation and
room-conditioning systems”.
Leaking ventilation systems consume unnecessary
energy. The more airtight the ducting the higher the
energy savings. Furthermore, leaking systems can
have negative effects on hygiene. Lack of air flow
rate in the destination due to leakages can have ne-
gative effects on the room conditions.
The airLPT216 air leakproof tester is used to deter-
mine the quantity of air leaked and the air tightness
class achieved according to EN 13779, or EN 1507 and
EN 12237, especially in HVAC systems. Due to the au-
tomatic determination of the air tightness class there
are a wide range of applications from very small sys-
tems (7 m2surface area) through to large systems.
The airLPT216 air leak proof tester, with its complete
equipment and integration in a stable plastic case,
has been especially designed for use on construction
sites. It weighs less than 9.5 kg and is therefore light
and easy to transport. The hoses and accessories are
handily packed in a stable plastic case.
Clear and user-friendly menu navigation makes the
device easy to operate. It is suitable for positive and
negative pressure tests. All connections, the display
and the thermal printer are clearly arranged on the
top. The air hose connection for the negative pressu-
re measurement is at the side.
The automatic measurement sequence to EN 1507
and EN 12237 lasts 5 min. The air duct system to be
tested is sealed off airtight from the rest of the sys-
tem. It is pressurised, the test pressure is controlled
automatically and is kept constant (as defined by the
standard +/- 5 %) and the leakage air rate is deter-
mined. The measurement record is printed out using
an integrated thermal printer or the data is transfer-
red to a USB stick.

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 m2surface 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.

all internal tests have been passed, or shows a cor-
responding error message. In case of fatal errors (er-
rors 3, 4, 5, 7, 8, 9), the device cannot be used, or only
to a limited extent, and must be handed in to the
servicing or sent to the manufacturer’s factory for re-
pair. (See also “Troubleshooting” section on page 60)
A test is also performed on the USB drive (6), where-
by it does not matter whether a USB stick is plugged
in or not.
If an error occurs, a warning appears on the display
(5) for 3 s. This error is NOT a fatal error, so that the
device can continue to be operated; however, without
the option of reading data onto the USB stick and
saving it.

POSITIVE PRESSURE
MEASUREMENT
Connect the air hose (7) for a positive pressure mea-
surement to the positive pressure air connection (8)
on the top of the device. Turning the hose coupling
slightly makes it easier to push on.
Connect the pressure measurement hose (10) to the
top of the device, at the pressure measuring connec-
tion (11). Connect both hoses to the measurement
connections on the air duct system to be tested.
These should be approx. 1.5 – 2 m apart and not be
opposite each other.
In case of pressures higher than 2,000 Pa, the two
measuring connections (air connection, pressure
measuring connection) must be additionally secured
against coming off suddenly.
The hoses must not be kinked, crushed or twisted.
The ductwork surface to be tested should be at least
10 m2for testing in conformity with the standards and
must be determined to EN 14239. The air duct system
to be tested must be sealed off airtight from the re-
maining system. Ensure careful sealing. Avoid using
film and adhesive tapes to close off the openings, as
in most cases this results in too large measurement
errors. The openings must be closed off properly, e.g.
using end caps. The air leakproof tester is connected
via prepared measuring openings. These can be, e.g.
flanged spigots, or inspection openings with approp-
riate adapters. According to EN 12599, the test pres-
sure, as positive pressure for supply air ducts and
negative pressure for exhaust air ducts, should be
200 Pa, 400 Pa or 1,000 Pa and lie in the middle of the
average operating pressure.

NEGATIVE PRESSURE
MEASUREMENT
Connect the air hose (7) for a negative pressure mea-
surement to the negative pressure connection (9) on
the right-hand side of the device. Turning the hose
coupling slightly makes it easier to push on.
Connect the pressure measurement hose (10) to the
top of the device, at the pressure measuring connec-
tion (11). Connect both hoses to the measurement
connections on the air duct system to be tested.
These should be approx. 1.5 – 2 m apart and not be
opposite each other.
In case of pressures higher than 2,000 Pa, the two
measuring connections (air connection, pressure
measuring connection) must be additionally secured
against coming off suddenly.
The hoses must not be kinked, crushed or twisted.
The ductwork surface to be tested should be at least
10 m2for testing in conformity with the standards
and must be determined to EN 14239. The air duct
system to be tested must be sealed off airtight from
the remaining system. Avoid using film and adhesi-
ve tapes to close off the openings, as in most ca-
ses this results in too large measurement errors. The
openings must be closed off properly, e.g. using end
caps. The air leakproof tester is connected via prepa-
red measuring openings. These can be, e.g. flanged
spigots, or inspection openings with appropriate ad-
apters. According to EN 12599, the test pressure, as
positive pressure for supply air ducts and negative
pressure for exhaust air ducts, should be 200 Pa, 400
Pa or 1,000 Pa and lie in the middle of the average
operating pressure.

Start the test by pressing the START button (F3). The
current pressure in Pa and the volumetric flow in l/s
(with two decimal places) are displayed continuously.
The automatic mode controls the pressure to the pre-
defined test pressure. As soon as it is within +/- 5%
accuracy, the actual test time of 5 minutes begins. A
counter indicates the remaining test duration. This
counter is stopped if the test pressure leaves the
above-named tolerance range during the test.
The automatic test can be ended prematurely by
pressing the STOP (F3) button. The measurement pe-
riod that has passed up to this time is then evalua-
ted. However, no statement is made as to whether
the test was passed or not, as it was not performed
in conformity with the duration of 5 minutes required
in the relevant standard (see EN 1507:2006 Clause
5.22).
If the leakage volume at the set test pressure is abo-
ve 36.0 l/s, the measurement is cancelled with the
following error message:
VOLUME FLOW TOO
LARGE! PLEASE REDUCE
TEST PRESSURE!
If the leakage volume at the set test pressure is be-
low the measurement limit of 0.08 l/s, the measure-
ment continues, but a specific measurement value
cannot be determined. As a result “Leakage volume <
0.08 l/s” is then output.

OPERATION
Manual test mode
This corresponds to automatic test mode, with the
exception that the test pressure must be adjusted
manually by changing the fan speed to the entered
target value.
After pressing the Start button (F3), the compressor
(fan) does not start automatically, but must be ad-
justed using the arrow buttons and to a speed
at which the preset pressure is kept within the limits
+/- 5 %. If the arrow buttons are pressed for longer
than 1.5 s, the compressor (fan) speed changes quickly.
The current pressure in Pa and the volumetric flow
in l/s (with two decimal places) are displayed con-
tinuously. In addition, a numerical value between 0
(speed = 0) and 4095 (maximum speed) appears in
the display (5) for orientation purposes and indica-
tes the speed of the compressor (fan). Whenever
the test pressure is within the tolerance window, a
countdown counter counts down from 5 minutes to 0.
The measurement ends after the time has expired or
by pressing the STOP (F3) button.
The evaluation uses the average of the measured
values from the entire test duration. However, if the
test duration during which the test pressure was wi-
thin the tolerance range band is less than 5 min, as
with the automatic measurement, no statement is
made whether the test was passed or not, as it was
not performed in conformity with the standard for a
duration of 5 minutes.
The same options for recording the test exist for
manual test mode as for automatic mode. (See also

Enter record header
The header of the printed record is made up of seven
lines, each with 32 characters and can be used to
show the company name and address. These lines
are still empty when the device is delivered to the
customer by the manufacturer.
The customer can configure the record header easily
as follows:
A text only file with the name “KOPF.TXT” (HEADER.
TXT) is created at the PC using the WINDOWS text
editor. It must be ensured that this file contains only
7 lines, each with 32 characters. Any additional cha-
racters and lines are ignored. This file is copied onto
a USB stick. The USB stick does not have to be empty,
i.e. it can contain other data. However, it must not
have a storage volume larger than 4 GB, to prevent
complications with the software. The “KOPF.TXT” file
should be in the root directory.
The “Enter Record Header” menu item is opened at
the airLPT216. The user is then prompted to plug the
USB stick into the USB port (6) at the top of the de-
vice.
The file is transferred and the record header is per-
manently saved in the device. If the process is com-
pleted successfully, which only takes a few seconds,
the user is informed.
Otherwise an error message appears (e.g. if the KOPF.
TXT files was not found on the USB stick).
