5 Storage
Danger of damage to the vacuum pump drive!
Long storage periods may cause capacitors in the drive to be weakened by electro-
chemical condensation. In the most detrimental case, this may cause short-circuit and
thereby destruction of the drive.
• The vacuum pump should therefore be connected to the power supply for 30 minutes
every 18 months.
Proceed as follows for storage:
• Close all openings with the protective caps included in the scope of delivery (penetra-
tion of dirt and water is prevented)
If storage for more than 3 months is intended:
• Secure loose cables
• Drain all process and operating media
• Clean and dry the vacuum system (Prior to storing make absolutely sure that all parts
are clean, drained and dry)
• Where necessary use oil for conservation
• Wrap the vacuum system in corrosion-inhibiting film.
• Store the vacuum system in a protected, dry and dust-free room at a temperature be-
tween 0 and 40 °C.
