Original Operating Instructions.
Obligation to Provide Information
Before installing and commissioning the equipment, carefully read these
Operating Instructions and follow the information so as to ensure optimum
and safe working right from the start.
The Leybold SCROLLVAC has been designed for safe and efficient opera-
tion when used properly and in accordance with these Operating Instructions.
It is the responsibility of the user to carefully read and strictly observe all safe-
ty precautions described in this section and throughout the Operating
Instructions. The pump must only be operated in the proper condition and
under the conditions described in the Operating Instructions. It must be oper-
ated and maintained by trained personnel only. Consult local, state, and
national agencies regarding specific requirements and regulations. Address
any further safety, operation and/or maintenance questions to our nearest
office.
DANGER indicates an imminently hazardous situation which, if not avoid-
ed, will result in death or serious injury.
WARNING indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
CAUTION indicates a potentially hazardous situation which, if not avoided,
could result in minor or moderate injury.
NOTICE is used to notify users of installation, operation, programming or
maintenance information that is important, but not hazard related.
We reserve the right to alter the design or any data given in these Operating
Instructions. The illustrations are not binding.
Retain the Operating Instructions for further use.

0 Important Safety Information
0.1 Mechanical Hazards
1 Avoid exposing any part of the human body to the vacuum.
2 Never put fingers or foreign matter into the pump‘s inlet or the clear-
ance of fan blades. If done, it can cause injury.
3 Make sure that the gas flow from the exhaust port is not blocked or
restricted in any way.
4 Pumps with single-phase motors have an internal thermal protector.
These motors restart without warning after the protector trips back.
0.2 Electrical Hazards
1 Wiring must be done by a qualified electrician. Otherwise there is the
risk of suffering an electric shock.
2 Prevent short-circuits with a ground fault circuit interruptor (GFCI) of
proper capacity. Failure to do so can result in electric shock or fire.
3 Be sure to install a main disconnect switch. Failure to do so can result
in damage, fire, or injury.
4 Be sure to disconnect the electric source before changing the wiring or
before an inspection. Failure to do so can result in electric shock or
damage by the rotating fan.
5 Ensure proper grounding of the pump. Otherwise there exists the risk
of suffering an electric shock or igniting a fire.
6 Install in an area which is not exposed to moisture such as rain or
steam. Exposure to moisture can cause eIectric shock.
7 Be sure to check wiring diagram before connecting a power supply.
Failure to do so can result in damage.
8 Be sure to disconnect the electric source before changing the wiring or
before an inspection. Failure to do so can result in electric shock or
damage by the rotating fan.
0.3 Thermal Hazards
1 Do the maintenance after the pump has fully cooled down. Performing
maintenance on a hot pump can cause burns.

GA01423_002_C0 - 10/2016 - © Leybold
0.4 Hazards Caused by Materials and Substances
1 Never pump toxic, explosive, flammable, corrosive gases, chemicals,
solvents or powders. Flowing substances, explosion or fire can cause
bodily injury.
2 Install the pump in an area without explosive or flammable substances.
Otherwise, it can cause explosion or fire.
0.5 Danger of Damages to the Pump
1 Ask a specialist to perform repairs. Otherwise there exists the risk that
the pump may fail, is damaged or its service life is severely reduced.
Trained customers may perform maintenance themselves.
2 Use at ambient temperatures of 5 - 40 °C (during operation). Operating
outside of this range can cause damage or shorten service life.
Always operate the pump with the fan and terminal covers in place.
Always operate the single-phase pumps with the capacitor cover in
place.
3 Conduct periodic maintenance and inspections. Failure to do so can
cause damage or reduced service life.
4 Be sure to close the isolation valve between pump and vacuum sys-
tem (chamber) during startup and shutdown. If this valve is open,
debris attached to the inside of pump can be drawn back into the vac-
uum chamber.

1 Description
1.1 Design and Operation
The SCROLLVAC vacuum pumps are oil-free vacuum pumps. Each
SCROLLVAC consists of two Archimedes spirals offset within each other by
180 °. Thus several crescent-shaped pockets of different sizes are created.
With the aid of an eccentric drive, the second spiral orbits about the fixed
spiral thereby reducing, respectively increasing the volume of the pockets
whereby the gases are conveyed from outside to inside thereby being com-
pressed.

Note 1: Pumping speed remains unchanged independently of whether the purge gas inlet is open or closed
Note 2: Noise level is measured at ultimate pressure in an anechoic room
Note 3: The leak rate is measured when the pump is stopped and the purge gas supply is closed (condition as delivered)
Note 4: When the pump is delivered, the purge gas inlet is closed
Note 5: The three-phase motors do not have internal thermal protection. Be sure to install the protection from the side of the remaining system.

Lift the pump only at the provided handles, respectively crane eyelets.
Exclusively use lifting facilities with sufficient lifting capability. Never stand
under the hanging pump when it is being moved.
Avoid any other orientations during transportation.

3.1 Checking the Product
Check that the package is right-side-up and then open it.
Check that model of the product is one that you ordered.
Check that there is no damage. If there is any damage, file a damage claim
with the carrier.
Remove inlet blank flange and outlet blank flange. If you operate the pump
with blank flanges in place, it can cause damage.
Check that the silencer for the purge gas inlet is present in the plastic bag.

3.2 Conforming Use
SCROLLVAC pumps can pump gases and vapours, and evacuate vessels or
vacuum systems in the fine vacuum range.
The pumps are suited for pumping water vapour within the specified water
vapour tolerance limits. Avoid vapours that can condense into liquids when
being compressed inside the pump, if these substances exceed the vapour
tolerance of the pump.
