Storage
Temporary storage
l
Make sure that the intake and exhaust flanges are closed (put on
the protective caps included in the delivery package of the vacuum
pump)
l
Store the vacuum pump
–
if possible, the vacuum pump should be stored in its original
packaging,
–
indoors,
–
dry,
–
in a dust-free and
–
vibration-free room
Removal of the pump
Before starting a vacuum pump that has been stored outside the buil-
ding for a while, the vacuum pump must be moved to a room with
ambient temperature, where it should rest for a day.
Preservation
If the vacuum pump will be exposed to unfavourable ambient condi-
tions (for example, aggressive environment, frequent temperature
changes), begin immediately with preservation work on the vacuum
pump.
In the case of favourable ambient conditions, perform preservation
work on the vacuum pump if a storage period of more than three
months is planned.
l
Make sure that all openings are hermetically sealed; use adhesive
tape to fasten loose parts (seal rings, flat seals, etc.).
NOTE
: VCI is the abbreviation for “volatile corrosion inhibitor”. The
VCI molecule is an organic corrosion inhibitor in the vapour phase.
Integrated in various carriers such as film, cardboard, paper, foam, li-
quid and powder, it protects the parts against corrosion as a result of
its action in the vapour phase. However, VCI packaging can attack syn-
thetic surfaces and surfaces of other elastomers. If in doubt, please
contact your nearest distributor. VCI packaging provides several years
of protection against corrosion, even under the harshest of conditions:
overseas shipment, extended storage before use.
l
Wrap the vacuum pump in a VCI film
l
Store the vacuum pump
–
if possible, the vacuum pump should be stored in its original pac-
kaging,
–
indoors,
–
dry,
–
in a dust-free and
–
vibration-free room
Start-up of the vacuum pump after storage:
l
Make sure that all protective elements, stoppers or adhesive tapes
attached before preservation have been removed
l
Switch on the vacuum pump in the sequence described in the
chapter “Installation and start-up”
Installation and start-up
Necessary installation instructions
CAUTION
If the necessary installation instructions are not followed and parti-
cularly in the case of inadequate cooling:
Risk of damage to and total destruction of the vacuum pump and its
components!
Risk of personal injury!
The necessary installation instructions must be followed.
l
Make sure that the integration of the vacuum pump in its new en-
vironment complies with the safety regulations according to the
Machinery Directive 2006/42/EC (regarding the responsibility of
the manufacturer of the system in which the vacuum pump is to be
integrated, see information in the Declaration of Conformity).
WARNING
Local regulations regarding the motors and electric control ele-
ments must be observed when installing the pump in potentially
explosive environments. Make sure before start-up that all safety
measures have been followed.
Installation site and installation
l
Make sure that the environment of the vacuum pump is not po-
tentially explosive
l
Make sure that the following ambient conditions are fulfilled:
–
Ambient temperature: 0 ... 40 °C (32 ... 104 °F)
–
Ambient pressure: atmosphere
–
Humidity range: 20 to 95%
–
Altitude: up to 1000 m
l
Make sure that the cooling water fulfills the following require-
ments:
–
Temperature: 10 - 25 °C
–
Water pressure: 2 - 5 bar (relative)
–
Approximate flow rate: min. 8 l/ min for the standard version
–
Water hardness: < 5° dGH
NOTE:
1° (german degree = 1° dGH) = 1,78° (french degree) = 1,25 e
(english degree) = 17,9 mg/kg CaCO3 (american hardness)
l
Make sure that the cooling water is neutral and clean
l
Make sure that the cooling water outlet is unpressurised
l
Make sure that the nitrogen fulfills the following requirements:
–
Overpressure: 1,5 bar
–
Standard flow rate dil1: 20 l/min
–
Standard flow rate dil2: 40 l/min
–
Max. flow rate: 200 Nl/ min
l
Make sure that the ambient conditions correspond to the protec-
tion class of the motor (according to 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
l
Make sure that the vacuum pump is at least 1 m away from any
wall to ensure good cooling
l
Make sure that the vacuum pump is easily accessible and that the
selected installation site fulfills the requirements for assembly/
dismantling
