CAUTION
Tilting a vacuum pump that is already filled with oil can cause large
quantities of oil to flow into the cylinder.
Starting the vacuum pump with excessive quantities of oil in the
cylinder will immediately break the lobes and destroy the vacuum
pump.
Once the vacuum pump is filled with oil it must not be lifted any
more.
l Prior to every transport make sure that the oil has been drained
(unless recommended otherwise)
Storage
Short-term Storage
l Make sure that the suction connection/ gas inlet and the discharge
connection/ gas outlet are closed (fit the provided plugs)
l Store the vacuum pump
–
if possible in its original packaging,
–
indoors,
–
dry,
–
dust free
–
vibration free
Switching off and conservation of the pump
Removal of the pump
Before starting up a vacuum pump that has been stored outside the
building for a while, the vacuum pump must be moved to a room with
ambient temperature, where it should rest for a day.
Conservation
In case of adverse ambient conditions (e.g. aggressive atmosphere,
frequent temperature changes) the vacuum pump must be preserved
after one week using a conservation agent inside the cylinder. In case
of favourable ambient conditions, the pump must be preserved using a
conservation agent inside the cylinder if the pump is to be stored for
more than 3 months.
CAUTION
Using the pump with the gas discharge connection closed will
damage the vacuum pump.
Make sure that the gas discharge connection is open.
CAUTION
During operation the surface of the vacuum pump may exceed
temperatures of 70°C.
Risk of burns!
Do not touch the hot housing.
l
Electrically connect the vacuum pump (see “Installation and
Commissioning, Installation, Connect Electrically”)
l Let the vacuum pump run for at least half an hour
l Switch off the vacuum pump
l Drain the conservation oil (see "Maintenance, Oil Change,
Draining Used Oil")
l Make sure that all openings are firmly closed; seal all openings that
are not closed with PTFE-tape, gaskets or o-rings, with adhesive
tape.
l Wrap the vacuum pump in VCI film
NOTE : VCI stands for “Volatile Corrosion Inhibitor”. VCI-products
(film, paper, cardboard, foam) evaporate a substance that condenses in
molecular thickness on the packed good and by its electrochemical
properties effectively suppresses corrosion on metallic surfaces.
However, VCI-products may attack the surfaces of plastics and
elastomers. Seek advice from your local packaging dealer! VCI
packaging ensures good protection against corrosion for a few years,
even in the most extreme of conditions such as see transport and
prolonged storage.
l Store the vacuum pump
–
if possible in its original packaging,
–
indoors,
–
dry,
–
dust free and
–
vibration free
Repeat the conservation process after 12 months of standstill.
CAUTION
Before a new conservation process or re-installation of the vacuum
pump, make sure that the gasket, plug or adhesive tape from the
discharge connection are removed.
Commissioning after conservation
l Make sure that all gaskets, plugs or adhesive tape are removed
from the openings
l Make sure that the oil level at the gears and bearings is in the
target circle of the oil sight glasses
l
Commission the vacuum pump as described in the chapter
“Installation and Commissioning”
Installation and
Commissioning
Installation Prerequisites
CAUTION
In case of non-compliance with the installation prerequisites,
particularly in case of insufficient cooling:
Risk of damage or destruction of the vacuum pump and adjoining
system components!
Risk of injury!
The installation prerequisites must be complied with.
l
Make sure that the integration of the vacuum pump is carried out
in such a way that the essential safety requirements of the
Machine Directive 2006/42/EC are complied with (regarding the
responsibility of the designer of the machinery into which the
vacuum pump is to be incorporated; see also the note in the
EU-Declaration of Conformity)
Local installation
l Make sure that the vacuum pump is switched off and cannot
accidentally be switched on again
l Make sure that the following ambient conditions are adhered to:
–
Ambient temperature : see “Oil”
–
Ambient pressure: atmospheric
l Make sure that the environmental conditions comply with the
protection class of the drive motor (according to the nameplate)
l Make sure that the vacuum pump is placed on or fastened to a
horizontal surface
l Make sure that the vacuum pump is level and even
