Leak detector Vakumatik IVF R34
6. Functional characteristics
-The leak detector (1) operates per the vacuum principle. A built-in vacuum pump (1.21)
evacuates air from the interstitial space (12) via the suction line (6) and compensates for
minor leaks in the system. The interstitial space is formed by the space between the two
tank walls or between the leak protection lining and the tank wall (11, 14). The evacuated air
is usually circulated back into the tank via the exhaust line (8). A pressure switch (1.23),
which is also connected to the interstitial space, identifies the pressure in the system and
controls the pump according to the specified switching values as well as the alarm signal
with major leaks of the leak detector system.
-Agreen power lamp (1.3) permanently indicates the operating condition of the leak detector
(voltage applied).
-A red alarm lamp (1.2) as well as the acoustic buzzer (1.18) indicate the alarm condition.
This acoustic alarm may be temporarily disabled by means of a switch (1.4). A yellow lamp
(1.5) will indicate a disabled buzzer.
-An alarm condition may, for example, also be forwarded to a central monitoring station via
terminal "A" found on the terminal strip (1.16) and/or via an isolated contact (1.17, optionally
installed or as an accessory).
-The normal operating condition has been reached once all connecting lines have been
connected, all test and locking devices (1.13/1.15) are in a secure operating position, the
power lamp is "ON", the alarm signal is "OFF", and the buzzer has been activated (yellow
lamp "OFF").
-Diagram 2 below describes the start-up operation sequence, normal operation and alarm.
Diagram 2
6.1. Media-touching materials of the leak detector
-The leak detector components, which touch the stored medium in case of a leak, consist of
the following materials:
Pump and pressure switch: NBR, PA
Connecting lines and connectors: PVC, POM

Leak detector Vakumatik IVF R34
7. Instructions for assembly
7.1. General information / Assembly site
-The leak detector may only be assembled outside an ex-zone.
-The conditions for use have to be observed as stated in section 5.
- The maximum ambient temperature (see section 3) must not exceed.
-The leak detector should be assembled in a closed, dry and frost-free room, if
possible.
-The leak detector and the mounting material provided in the scope of delivery should be
mounted to a wall or mounting plate easily accessible, visible and, if possible, at eye level.
Hole separation 156 mm (drill template included in the package). Cover screw domes inside
the bottom part of the housing with protective caps (included in separate package).
-The lateral wall clearance of the air vents must be at least 3 cm.
-The leak detector must be assembled such that it is not subjected to direct sunlight or direct
heat.
-If for structural reasons the leak detector must be assembled outside of closed and dry
rooms, the leak detector must be installed into a weather-resistant protective housing (IP55,
available as accessory from the manufacturer) and equipped with an additional exterior
alarm.
-If ambient temperatures of below -5°C are expected at the assembly site, an additional
heater with thermostat must be installed (special equipment).
7.2. Assembly of the liquid barrier (9)
-Prior to installing the liquid barrier, check its float
gauge seal for cleanliness.
-Aliquid barrier and a condensate vessel (10), see
accessories, should be installed near by the
container's suction pipe nozzles.
7.3. Assembly of the Connecting pipes (6,7,8)
-Ensure proper allocation of the suction, measuring
and exhaust line at the leak detector and the tank
(see service flap).
-Connecting lines must be color-coded: suction line
(6) = white, measuring line (7) = red, exhaust line (8)
= green.
-Connecting lines between leak detector and tank
must be equipped with PVC hoses NW 6 (6x2 mm)
or similar, ensure stability.
-Do not fold or pinch connecting lines.
Ø 6mm
Ø 4mm
12

Leak detector Vakumatik IVF R34
-The total length of the connecting lines between leak detector and tank may not exceed 50
m at an internal diameter of 6 mm.
-Plastic connecting lines laid underground or
aboveground must be laid in conduits.
Conduits encasing connecting lines laid
aboveground must also be impact- and
weather-resistant.
- The connecting lines must be laid from the
leak detector to the tank connections at an
incline of ca. 4° to avoid the accumulation of
condensate in the connecting lines, which
could freeze at cold temperatures. If it is
impossible to lay the lines at an incline, a condensate vessel (10) must be installed at all low
points of the respective connecting line.
-Connect the connecting lines, suction line (6), measuring line (7) to the interstitial space and
the exhaust line (8) to the ventilation adapter (EV) of the tank ensuring a tight seal.
7.4. Electric connection
The electric connection of the leak detector may only be performed by an electric
specialist.
The connection data (see Technical Data, Section 3) and device nameplate must
be taken into account.
Disconnect the power supply to the device prior to opening it.
Switches or connectors inside the electric supply line are not permissible.
The electric supply line to the leak detector must be protected with max. 16 A.
It is recommended to connect the leak detector via the fuse of a frequent
consumer (e.g. lamp in basement, hallway). This way, a power outage will be
detected promptly.
If the leak detector is installed inside the protective box or in difficult-to-reach
locations, an additional exterior alarm must be connected.
-The electric supply line (e.g. NYM-J 3x1.5 mm²) must be run into the housing from above via
the cable connection. Please be sure to run the cables above the air duct, touching neither
pump, buzzer nor heater (hot parts). The terminal is suited for strand cross sections up to
max. 1.5 mm², and the cable bushings are suited for cables with an exterior diameter of
6-10mm.
-Additional connecting lines (e.g. for exterior alarms or external alarm signals via isolated
relay) may be connected via the 2 additional openings at the top of the device using
appropriate cable bushings (M16).
-The electrical connection (L, N, PE and A) terminal board of the leak detector must be
performed in accordance with the connection diagram of the electrical diagram (see Section
7.5).
-The voltage drop signal and the alarm condition can be identified at the leak detector via the
optionally installed isolated relay (e.g. for forwarding to a switch room or data
communication module).

8. Starting up
Please ensure that the leak detector has been assembled and connected correctly as
detailed in section 7.
During evacuation, starting up and operation, harmful gases may leak from the
interstitial space via the pump's outlet (exhaust) opening. Do not inhale, ensure
sufficient ventilation.
8.1. Evacuate the interstitial (monitoring) space
-For small interstitial spaces, the integrated vacuum pump may be used in order to generate
the vacuum.
-Asuitable external vacuum pump can be used in order to evacuate a bigger interstitial
space more quickly.
-The leak detector will signal an alarm until the alarm switch-off point has been reached. The
red indicator lamp (1.2) goes out and the buzzer (1.18) switches off
(see diagram in section 6).
-The green power lamp (1.3) must always be on.
-The pump switches off automatically as soon as the pump switch-off value PPA is reached.
8.2. Functional testing
It is the purpose of the functional testing to determine efficient functionality of the leak
detector. The testing must be performed by a qualified person:
-prior to starting up the leak detector
-once a year
-in the event of any operational defect or if the alarm signal is activated
without apparent reason
-In case of need, the hoses at the leak detector may only be disconnected when
they were previously sealed off with means of appropriate clamps. Otherwise the
disconnection may cause complete aeration of the interstitial space, which may
cause, for example, the flexible leak protection lining to disattach from the
interior tank wall and thus rendering the tank unusable.
-If it becomes necessary to open the leak detector housing for maintenance
purposes, the leak detector must be disconnected from the voltage supply first.
-After opening the housing, the motor / pump surface may still be at operating
temperature - caution very hot
-Loosen seal at the right side of the
service flap and open until it
interlocks.
15

Leak detector Vakumatik IVF R34
Continuity test leak detector, connecting lines and interstitial space; leak test of the
entire leak detection system:
-Connect appropriate test device (e.g. THOMAS VDM300) to the test valve of the measuring
line (1.13), establish a connection to the measuring device by turning the valve head.
-Slowly turn valve head at the test valve
of the suction line (1.15) in the specified
direction; the interstitial space (12) will
be inflated.
-An immediate pressure change at the
measuring device proves the continuity
of the leak detector with the interstitial
space.
- This setup can also be used to test the leak tightness of the entire leak detection system.
Leak detector inspection (interstitial space disconnected via 3-way valves):
- Bridging both test valves facilitates verification of the pressure switch's (1.23) switching
values, an vacuum test of the pump (1.21) and a leak test of the leak detector (1). It is also
recommended to install a test volume and a throttle valve into the bridging line.
-Functional testing of the red alarm
lamp (1.2) and the acoustic buzzer
(1.18) as well as potentially externally
connected alarm devices when reaching
the alarm switch-off point PAE.
-Testing the function "Acoustic Alarm
OFF". The buzzer (1.8) is temporarily
turned off by the alarm switch (1.4). The
yellow signal lamp (1.5) indicates that
the acoustic alarm has been disabled.
16

Leak detector Vakumatik IVF R34
-Verification of setting values of the leak detector
(see Section 4.1):
„Alarm On“ PAE and „Pump Off“PPA.
If these values are incorrect then the correct values
can be set by means of the pressure switch (1.23).
-Verification of the values "Pump On" PPE and
"Alarm Off" PAA. These values are not set, but
rather result from the switching hysteresis of the
microswitches for alarm and/or pump control.
Specified values are reference values.
- During the functional test, check the pump / motor
(1.21) for abnormal operating noises.
-In the above mentioned valve position, the leak
detector may also be checked for leak tightness.
Interstitial space inspection (leak detector disconnected via 3-way valves):
-In the following position, the interstitial
space (12) may be checked without leak
detector, for example, for leak tightness.
Maximum pump vacuum test:
-By connecting the measuring device to
the test valve of the suction line (1.15),
the maximum pump vacuum may be
tested using the position specified on
the left.
-Pump must generate vacuum of at least
-300 mbar.

Leak detector Vakumatik IVF R34
Completion of functional test:
-Bring the 3-way valves into the operation
position shown on the left.
Otherwise, the service flap will not close
properly.
-Tightly connect any disconnected connecting
lines.
-Under no circumstances leave the system
in this condition; the monitoring of the leak
detection system cannot be fully
guaranteed.
-The vacuum pump creates the vacuum build up the pressure inside the interstitial space
until the pump switch-off value PPA has been reached. Subsequently the pump will turn off.
-To complicate or to be able to recognize
unauthorized engagement with the leak detector, the
closed service flap (1.11) must be secured with the
housing bottom (1.9) using a seal (1.12).
Final visual inspection:
-Power lamp "Green" (1.3) is on, alarm lamp "Red" (1.2)
is off.
-Switch for the acoustic alarm (1.4) in normal operating position, the yellow
lamp (1.5) must be off. In addition it is recommended to secure the switch
with a safety label (see image on the right). Operation of the alarm switch
will be indicated by the break protection.
-Valves potentially installed in the connecting lines must be in operating
position and secured.
-Condensate vessels (10) must be empty.
-General visual inspection of the system (e.g. labelling, damage, folded or
porous connecting lines).

9. Instructions for use
9.1. General advice
During evacuation, starting up and operation, harmful gases may leak from the
interstitial space via the pump's outlet (exhaust) opening. Do not inhale, ensure
sufficient ventilation.
Proper monitoring of the system and/or the tank requires proper installation, starting up and
regular functional tests as well as leak detector checks.
The operating frequency and operating duration of the integrated pump to compensate for
minor leaks conforms with the volume of the interstitial space and the leak tightness of the
overall leak detection system. In general: The larger the tank and thus the volume of the
interstitial space, the lower the operating frequency of the pump, however correspondingly
longer operating duration. A continuously increasing operating frequency suggests increasing
leaks inside the leak detection system. If the pump operates increasingly longer or even
continuously, the reason may be decreasing pump performance. In both cases, an inspection
of the leak detection system is recommended.
The green power lamp (1.3) remains on as soon as voltage is applied to the leak detector (1).
An optimally maintained and leak-tight leak detection system reduces operating costs to a
minimum.
9.2. Maintenance
-The user must regularly check the functionality of the power lamp "Green" (1.3), as well as
the fill level of the condensate vessels (10).
-Aqualified person must perform an annual functional check as specified in Section 8.2.
-Condensate or the stored medium may be present in the condensate vessel (10). When
emptying the tank, appropriate security measures must be taken. The condensate must be
disposed off properly.

9.3. Advice in the event of a fault or if the alarm is triggered
In the event of any fault and if the leak detector's alarm has been activated, the indicator lamp
"Alarm red" (1.2) lights up and the inbuilt buzzer sounds (1.18). Qualified staff or authorised
specialists should be called immediately in order to identify the fault.
The acoustic alarm (1.18) can be temporarily switched off using the alarm switch (1.4) at the
leak detector. The yellow lamp (1.5) indicates a disabled buzzer.
Possible reasons for a fault:
- a leak in the system, resulting the alarm initiation value is reached
-pump or pressure switch defective
- connection lines (also exhaust lines), filter, liquid barrier clogged or icy
-condensate vessels or water traps are full, liquid barrier closed
- electrical defect
- pump fuse defective
Reasons for a leak might be:
-leaky connections, connecting pipes / tubes, condensate vessel or liquid barrier
-faulty diaphragm or valves within the pump or the pressure switch
-connecting fittings on the container (tank)
- leaky container (tank) or leak protection lining
Initial steps for failure detection:
Perform functional testing pursuant to Section 8.2 (test leak detector set points and leak
tightness of the system).
Restart of the system after failure:
After the malfunction or alarm has been corrected, the leak detector must be started back up
as specified in Section 7.0.
