End of the tests
Danger of fire and explosion.
Do not store any flammable materials in the box of the VACUUM PUMP. Allow the
VACUUM PUMP to cool down before putting it into storage.
Once testing has finished, disconnect the power supply cord from the electricity
supply.
• Remove the hose (7) from the VACUUM PUMP (1) and VACUUM BOX (2) and place it in the case (3).
• Close the case (3).
Preparing and commissioning the VACUUM BELL with VACUUM PUMP
Danger of injury from glass fragments during commissioning.
Excessive negative pressure or damaged glass may lead to implosion.
Protect the equipment from mechanical damage such as an impact or fall. Do not use the
VACUUM BOX or VACUUM BELL if they are defective.
Wear protective goggles. Danger of implosion
Connect the device to an outlet with a protective conductor. Any interruption of
the protective conductor inside or outside the device is dangerous!
Use extension cables with protective conductors only!
• Open the case. The VACUUM PUMP (1) is mounted inside the case (3) and must not be removed for use.
• The cooling air intake of the VACUUM PUMP (1) must never be obstructed or clogged. (Fig. L)
• Check the hose (7) for damage.
• Check the VACUUM BELL (2) for any faults (such as cracks, fissures, or scrapes) before every use. A defective
VACUUM BELL (2) can cause an implosion.
• Prior to commissioning, check the power supply cord, the plug, and the extension cable for electrical and me-
chanical damage.
• Connect the hose to the VACUUM BELL (2) (Fig. M) and the VACUUM PUMP (1) (Fig. N).
• Open the lever. (Fig. O)
• Connect the VACUUM PUMP (1) to nominal voltage. The nominal voltage specified on the device must match the
mains voltage. (CAUTION: Pump starts immediately)
