Important safety instructions

Warning
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 mechanical 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.

Caution
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 off 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.
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 off in the event of a mains voltage failure.

Application

Any other use or any use beyond the type of use described for the VACUUM PLATE 300 is deemed non-intended use. Test operation is not permitted in case of condensation (e.g. rain).

Technical data

Subject to change without prior notice.

Transport

Warning
Do not use the carrying handle (8) on the device for transporting with a crane.

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.
• 230 V~ up to 50 m 3 × 1.5 mm2 up to 100 m 3 × 2.5 mm2
• 120 V~ up to 50 m 3 × 1.5 mm2 up to 100 m 3 × 2.5 mm2

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.

Preparation and operation

• 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.

Test with VACUUM PLATE

• 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 off 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

Frequently asked questions, causes and actions VACUUM PLATE 300

Do not allow test pressure to build up

• 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.

Diaphragm is touching the sight glass (6)

• Reduce the pressure with the pressure adjustment valve (Vari-Flow Valve) (9).

Device-protective circuit-breaker (13) trips during operation or does not lock into place (recognizable by protruding reset button)

press the reset button on the device protection switch and repeat the process.
Defective vacuum motor| If the device circuit breaker switches the device off again immediately after resetting, the device must be inspected by an authorized Leister service center.
