VACUUM PLATE 300
testing device
Operating instructions (Translation of the Original User Manual)
Dangerous voltage, danger to life from electric shock:
There are live components inside the device. Maintenance and repairs are to be carried out by
trained specialist personnel only. If the housing is damaged, the power cord must be disconnected
from the power source immediately. Keep the device away from moisture and wet conditions.
Before starting, check the power cord, the plug and the extension cable for electrical and mechan-
ical damage.
Fire and explosion hazard
Admixtures (e.g. combustible or explosive gases or vapors), traces of oil, oil vapor and grease must not
be sucked in. Any operation in a potentially explosive environment is prohibited. The device must
only be operated with the filter plate installed.
No hazardous leak tracer is to be used for testing the weld seams. There is a risk of inhalation
of liquid particles. Read the material safety data sheet from the manufacturer of the material and
follow that company's instructions.
Risk of injury from plastic chips at startup.
Damaged plastic glass can lead to implosion. This may cause eye injuries. The plastic glass must
be protected against mechanical damage by impact or fall, for example. Do not put a defective VACU-
UM PLATE into operation. Wear protective goggles.
Vacuum blower causes high noise levels. There is therefore a risk of hearing damage while
operating the device. Wear hearing protection.
Risk of inhalation of dust particles while operating the device. If the membrane is contaminated,
dust particles can be sucked in and ejected by the blower. The membrane must be free of impuri-
ties in the test area.
If the device is being used on construction sites, a fault current circuit breaker must be used to
protect site personnel from electrical shock due to dampness and moisture.

2. Application
The local supply voltage must match the nominal voltage specified on the device. Incorrect mains
voltage can cause the device to fail. The main switch must be switched o in the event of a mains
voltage failure.
Risk of burns
The device may only be operated at intervals. If the on duration is too long (>2min), the temperature
on the motor housing can cause burns. Always allow the device to cool down. The device can only
be operated using the handles and switches provided. The main switch must be switched o in the
event of a mains voltage failure.
The device should only be operated by trained specialists or under their supervision. Children are not
permitted to operate the device.
Be aware of hazards in the surrounding area, e.g., risk of tripping, risk of slipping, strong sunlight,
unattended equipment, etc.
Note
Caution
2.2 Non-intended use
2.1 Intended use
Any other use or any use beyond the type of use described for the VACUUM PLATE 300 is deemed non-intended use.

Power cord and extension cable
• The power cord (1) must be able to move freely and must
not hinder the user or third parties during work (trip hazard).
• The extension cables must be authorized for the utilization
site (such as, outdoors) and be marked accordingly. Take the
necessary minimum cross-section for extension cables into
account as required.
On-site generators for power supply
When using on-site generators as a power supply, please ensure that the generators are equipped with residu-
al-current circuit breakers.
The formula "2 × nominal power of the devices used" applies to the nominal power of generators.

6.2. Preparation and operation
Turn clockwise (+)
pressure setting valve closed/maximum pressure
Turn anti-clockwise (-)
pressure setting valve open/minimum pressure
• The welding area must be dry and free of contamination. Dirt particles may compromise the test.
• The seam area to be inspected must be sprayed with a liquid forming bubbles (e.g. soapy water) directly
before the inspection. The liquid must not damage the seam and the weld material.
• Set the pressure setting valve (Vari-Flow Valve) (9) to minimum pressure before the test. Turn counter-
clockwise until stop (-).
• Position the VACUUM PLATE on the location to be tested
• Place the VACUUM PLATE so that the seam to be tested is approximately in the middle of the longitudinal axis
of the testing device. For longer test sections, the VACUUM PLATE needs to be repositioned accordingly. When
moving the VACUUM PLATE, the test areas must be overlapped.
• In order to generate a negative pressure, the VACUUM PLATE must be pressed lightly on the location to be
tested with bothhandles (8).
• Turn on the main switch (2) on the VACUUM PLATE
• Turn the pressure setting valve (Vari-Flow Valve) (9) clockwise (+) until the desired or specified test
pressure is set.
• The existing negative pressure can be read on the manometer (5).
• Visual inspection of the weld seam for leaks
• The seam is sealed if there are no bubbles in the test liquid.
• Switch o the main switch (2) of the VACUUM PLATE, let the device cool down
• Then disconnect the power cord (1) from the electrical mains.
• Mark and repairany leaks
• Before each start, check the VACUUM PLATE for faults and damage, e.g. cracks, splits or scratches; a defec-
tive VACUUM PLATE can implode
• Visually inspect that the filter plate (4) is present and whether it is clean.
• Check the power supply line and plug (1) as well as the extension cable for electrical and mechanical
damage.
• Check the cooling air openings (11) must be open at all times and air must be able to be suctioned and
purged unhindered
• Ensure the sealing lip (7) is not damaged
• Warning: Excessive damage to the sealing lip (7) may prevent the required test pressure from being reached.
• Connect the VACUUM PLATE to the nominal voltage. The nominal voltage specified on the device must
match the supply voltage.

Causes Action
Ambient temperature too high (> 60°C)
Allow the device to cool down. Then press the reset
button on the device protection switch and repeat the
process.
Defective vacuum motor
If the device circuit breaker switches the device o
again immediately after resetting, the device must be
inspected by an authorized Leister service center.
Excessive on-time The appliance may only be operated at the prescribed
intervals
• Reduce the pressure with the pressure adjustment valve (Vari-Flow Valve) (9).
• Check the flatness of the membrane while pressing the VACUUM PLATE. The VACUUM PLATE can compensate
an unevenness of approx. 10 mm via the sealing lip (7). There is a risk of leakage if there is a higher level of
unevenness.
• Check whether the sealing lip (7) is damaged. If the sealing lip is damaged, there is a risk of leakage.
• Filter plate (4) clogged. Clean the filter plate with a brush with plastic bristles.
