Safety information

General safety
information

Indicates procedures that must be strictly observed to prevent

Warning

hazards to persons.

Indicates procedures that must be strictly observed to prevent
damage to, or destruction of the appliance.

The Leybold Oil-free Scoll vacuum pump is designed for safe and efficient
operation when used properly and in accordance with this manual. It is the
responsibility of the user to carefully read and strictly observe all safety pre­cautions described in this section and throughout the manual. This product
must be operated 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
your nearest Leybold Vacuum office.

Failure to observe the following precautions could result in serious
personal injury.

■ Never pump toxic, explosive, flarmmable, corrosive gases,

chemicals, solvents or powders.

Flowing substances, explosion or fire can cause bodily injury.

■ Install in an area without explosive or flammable substances.

Oherwise, it can cause explosion or fire.

■ Wiring must be done by a qualified electrician. Otherwise,

electric shock may occur.

■ Prevent short-circuit with ground fault circuit interuptor (GFCI)

of proper capacity.

Failure to do so can result in electric shock or fire.

■ Ask specialist to perform repairs. If not , it can cause failure,

damage or shorter lifetime. Trained customers may perform
maintenance themselves.

■ Be sure to install a main disconnect switch.

Failure to do so can result in damage, fire, or injury.

■ Be sure to disconnect the electric source before wiring or

inspection. Failure to do so can result in electric shock or
damage by the rotating fan.

■ Be sure to ground. Failure to ground can result in electric

shock or fire.

Caution

Start or stop after

closing isolation

valve

Never put fingers or foreign matter into the pump's inlet or the
clearance of cooling fins. If done, it can cause injury.

Install in an area which is not exposed to moisture such as rain
or steam. Exposure to moisture can cause eIectric shock.

Never alter the equipment. Modifications can damage the
equipment of shorten its lifetime.

Be sure to check Wiring diagram before connecting a power
supply. Failure to do so can result in damage.

Pumps with single-phase motors have an internal thermal pro­tector. This motor restarts without warning after the protector
trips.

Be sure to switch off the electric power before maintenance or
inspection. Failure to do so can result in electric shock or
bodily injury by rotating objects.

Install in a proper location.

■ Install on a level foundation (an inclination of less than 5°)

■ in a location free of dirt or dust from iron, stone or wood.

■ in a location free of corrosive gas.

Failure to install in a proper location can result in damage,
decrease in performance or shorter lifetime.

Use at ambient temperatures of 5 - 40 °C (during operation).
Operating outside of this range can cause damage or shorten
lifetime.

Do not operate when the fan cover is removed.
Do not operate, when the terminaI cover is removed.
Do not operate the single-phase pump when its condenser cover
is removed.

Conduct periodic maintenance and inspections.
Failure to do so can cause damage or shorter lifetime.

Do the maintenance after the pump has fully cooled down.
Performing maintenance on a hot pump can cause burns.

Be sure to close the isolation valve between pump and vacu­um system (chamber) during startup and shutdown.

If this valve is open, debris attached to inside of pump can be
drawn back into the vacuum chamber.
