personnel. In case of potential safety hazards, these must be assessed and measures taken
to avoid hazards. Uses that endanger health and life are not permitted.
Applicable operating instructions from the operator and the national regulations for accident
prevention, safety and occupational safety must be heeded.
PROTECTIVE CLOTHING
►For applications that require protective clothing, this clothing must be
worn for personal safety.
►The operator must specify the type and manner of protective clothing!
2.4 Special hazards
EMERGENCY OFF
►In dangerous situations, de-energize the device by pressing the power
switch or disconnecting the power plug.
DE-ENERGIZED STATE
►When the device is de-energized, all valves are closed and the motor
stops.

Safety
Operation Manual LVS 105 T –10 ef+13
2.4.1 Hazardous materials in general
WARNING
►Hazardous materials in the medium to be conveyed can cause personal
injuries and property damage.
►Heed the warning and safety instructions for handling hazardous mate-
rials!
HAZARDOUS MATERIALS
►For applications with materials with H and P classes, measures must
be taken to protect the health of people and the environment.
►The operator must –taking into account the applicable regulations –
assess the possible hazards in order to prevent personal injuries and
damage to the environment and property.
The operator bears responsibility for this!
For applications with hazardous materials, the following must be heeded:
Adhere to the requirements of the manufacturer's safety data sheets for hazardous mate-
rials.
Prevent the escape of poisonous and environmentally-damaging substances from the ap-
paratus.
To protect the environment and the apparatus, use a separator (e.g. condenser).
Check the strength and leak tightness of the connecting lines.
Check the proper installation of the sensor in the vacuum apparatus.
MATERIAL RESISTANCE
►In case of applications with aggressive media, the resistance of device
parts that come into contact with the media must be evaluated by the
user (see section 3.5 Parts in contact with internal gas).
SERVICE / REPAIR
►Service and repair by the manufacturer or in authorized facilities only
with transfer of the completely filled-out damage report with decontam-
ination declaration.
The damage report form is available for download from our website www.gardnerden-
ver.com/de-de/welch on the "Service" menu „Damage reports“.

Safety
14 Operation Manual LVS 105 T –10 ef+
2.4.2 Explosive gases
The device is not suited for operation in areas subject to explosion or for conveying media
that can form explosive mixtures.
The device is not certified as per ATEX Directive 2014/34/EU.
When using the device in areas subject to explosion, the system operator is obligated to ad-
here to the ATEX 137 Directive 1999/92/EC.
DANGER
►Caution, risk of explosion due to critical applications.
►With use of the device in an atmosphere subject to explosion or in ap-
plications where explosive mixtures can form, there is danger to life.
►The operator must ensure that the application and the area are not po-
tentially explosive.
2.4.3 Electricity
DANGER
►There is danger to life when opening the device. Touching exposed
electrical conductors can cause immediate death.
►Opening the device is generally forbidden; this may only be done by
specialists.
►Before opening the device, disconnect the power plug!
Heed the following instructions:
Operating the device without the housing is forbidden.
Only the manufacturer, authorized workshops or trained personnel may change the
power supply, display or printed circuit board.
If the device is defective, switch it off and disconnect the power plug.
Only use the supplied standardized power plug.
The power plug and cable must be in perfect condition.
The electrical network must have protective conductors in accordance with
IEC 60364-4-41. The protective conductor may not be interrupted.
Note that the device must be regarded as a portable tool.
2.4.4 Mechanics
NOTE
►In case of improper use or manipulation of the device, there can be
property damage to the connected vacuum pump or vacuum appa-
ratus!
Operate the device only according to this operation manual and the instructions in the opera-
tion manuals for the connected devices.
This device is not permitted to be operated with overpressure.
Solid and liquid materials in the gas being conveyed can compromise the function of the sen-
sor and valves. Prevent the penetration of solid particles into the vacuum apparatus.

Safety
Operation Manual LVS 105 T –10 ef+15
2.4.5 Vacuum
WARNING
►Hazard due to sudden ventilation of the vacuum apparatus.
►Due to sudden ventilation, the vacuum apparatus can explode.
►Prevent sudden ventilation. Check the pressure in the vacuum appa-
ratus before you disconnect the pneumatic connections.
A vacuum can also exist in the vacuum apparatus when the device is
switched off.
GLASS APPARATUS
►Glass apparatus is especially endangered.
Make sure that the glass apparatus is vacuum-proof and non-breaka-
ble.
2.5 Device-specific hazards
2.5.1 Reliable operation
CONVEYING VAPORS
►When conveying vapors, condensation may form inside the vacuum
pump. This can (greatly) reduce the service life of the components.
►The device must be at operating temperature before applications are
started. This will reduce condensation formation in the vacuum pump.
Do not operate the device without a separator or emission condenser. The separator can
only be emptied after the vacuum system has been ventilated. The condensate must then be
disposed of in accordance with legal requirements.
Note possible hazards caused by the required substances (see section 2.4.1 Hazardous ma-
terials in general)!
In addition, note the following:
It is not permissible to use the device to convey liquid materials.
The exhaust line must be freely and sufficiently sized.
The exhaust line must be routed in such a way that the condensate can drain.
Check the glass apparatuses for damage before use.
2.5.2 Temperatures
MEDIA/OPERATING TEMPERATURE
►The permissible media temperature must not be exceeded.
►Ensure that the maximum ambient temperature is not exceeded. Suffi-
cient ventilation around the device must be ensured.
►Values for permissible operation: see section 3.2 Characteristic values.

Safety
16 Operation Manual LVS 105 T –10 ef+
2.5.3 Operating fluid
CAUTION
►Risk of injury from contact with cold surfaces!
►When using very cold coolants, surfaces such as those on the emis-
sion condenser can become dangerously low.
►The operator must ensure safe operation and take measures to protect
the user if necessary (see sections 2.3 Protective measures and 6.3.1
Access control).
2.5.4 Vacuum controller –system functions
The following settings for the "control systems" must be assessed separately for particular
vacuum applications (see section 6.2.6 System settings).
"Allow ventilation"
When this function is activated, the application can be manually (see section 4.6.1 Opera-
ting elements and display) or automatically ventilated via the pressure control.
Through activation of the function, media, which may be harmful, can escape from the
application and enter into the environment.
ATTENTION
►If the function is activated, there is a possibility that the ambient air will
enter into the applications.
This can result in uncontrolled reactions in the application.
►Note that an inert gas may need to be connected to the ventilation
valve (see sections 3.4 Application connections and 4.3.2 Back of the
device).
"Auto Start"
If the "Auto Start" function is activated, the device starts automatically after
a power failure or after the power switch was pressed. This can cause undesired after-
effects in your application.
An automatic start only occurs if an operating mode was started previously.
Make sure that critical applications are not unsupervised!
WARNING
►Activating the "Auto start" parameter in the system setting can result
in hazards for the user and his environment.
►Check system settings with automatic start-up function and assess
possible hazards for your application!
Both system settings are not activated in the factory setting. Before you activate the func-
tions, make sure that there is no hazard with your application. The operator must assess
possible hazards in order to guarantee the safety of users!
Unauthorized activation of the functions can be prevented with an ADMIN password (see
section 6.3.1 Access control).

Safety
Operation Manual LVS 105 T –10 ef+17
2.5.5 Network safety
NOTE
►The vacuum controller of the device is network-capable via the LAN
connection. This introduces the possibility of external access to the
vacuum controller (or the device). Unauthorized access can cause ma-
nipulation of the applications.
The operator must guarantee network security in order to prevent un-
desired access to the vacuum controller (or the device).
