1. 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 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.
