• Place the pump on a stable and even surface before
switching the power on.
Inhalation of or contact with media
such as poisonous liquids, gases,
spray mist, vapours, dusts or biolog-
ical materials can be hazardous to user. Make sure con-
nections are tight and free from leaks when dealing with
such media.
• The pump system is not designed to be explosion proof.
Ensure that the temperature of the medium being evacu-
ated with the vacuum is below the ignition temperature.
Attention must be paid to temperature rise of medium
while being evacuated.
• Do not operate the appliance with hazardous substances or
under water.
• Tasks with the device must only be performed when op-
eration is monitored.
• There may be electrostatic discharges between the me-
dium and the drive which could pose a direct danger.
•
Read the operating instructions fully before starting up
and follow the safety instructions.
• Keep the operating instructions in a place where they can
be accessed by everyone.
• Ensure that only trained staff work with the instrument.
• Follow the safety instructions, guidelines, occupational
health and safety and accident prevention regulations.
• Wear your personal protective equipment in accordance
with the hazard category of the medium to be processed.
There may be risk from glass breakage.
Do not operate pump when front
cover is open. This may lead to seri-
ous injury if hand is caught in mov-
ing parts as internal parts are moving at a very high speed.
• Always ensure that front cover is attached before starting
up the device.
• Do not lift the pump if top motor cover is not tighten
properly.
• Do not switch the pump on in the vertical position as it is
not stable in this position.
Safety Instructions
• Always operate the pump in the horizontal position.
• Safe operation is only guaranteed with the accessories de-
scribed in the ”
Accessories
” chapter.
• Only authorized personnel are allowed to disassemble the
appliance.
• The device can only be disconnected from the power sup-
ply network by pulling out the mains plug or the connec-
tor plug.
• The socket for the mains cord must be easily accessible.
• Position the positive pressure outlet of the vacuum pump
under a fume hood.
• Refer to the operating instructions for the equipment this
vacuum pump is connected to, e.g. rotary evaporator.
• The motor is shut down by a thermal cutout safety switch
in the winding.
- Manual reset is necessary. Switch off device or isolate the
equipment from mains. Wait approx. five minutes before
restarting the device.
- Use device in conditions specified in “
Technical Data
”
section.
• Do not use pump to generate pressure.
• Maximum pressure at gas inlet or outlet should not ex-
ceed 1 bar.
• Use solenoid/check valves if there are several load devic-
es.
• Use only flexible hoses.
For protection of the equipment
• The voltage stated on the type plate must correspond to
the mains voltage.
• Socket must be earthed (protective ground contact).
• Removable parts must be refitted to the appliance to pre-
vent the infiltration of foreign objects, liquids etc.
• Protect the appliance and accessories from bumps and im-
pacts.
• The instrument may only be opened by experts.
• Do not cover the ventilation slots of the instrument in
order to ensure adequate cooling of the instrument.
• Use only genuine spare parts for maintenance to ensure
good working condition of the instrument.
• Pay attention to water condensation in and outside of the
instrument. Allow instrument to warm up if brought in from
a cold environment.
• Do not use the pump to evacuate any solid substance as
this will damage the diaphragm and the internal parts of the
pump.
• Do not use the pump to evacuate liquids as it will reduce
the lifespan of the diaphragm and cause leakage.
• Ensure that any substances to be used with the instru-
ment are compatible to the materials of the “
Wetted
parts
” of the device; see section “
Technical data
”.
