Safety information!
General information
Read and comply with this manual before installing or operating the equipment.
Transport the pump at the provided handle.
Remove all packing material, remove the product from its packing-box, remove the
protective covers from the inlet and outlet ports and keep, inspect the equipment.
If the equipment is damaged, notify the supplier and the carrier in writing within three
days; state the item number of the product together with the order number and the
supplier’s invoice number. Retain all packing material for inspection.
Do not use the equipment if it is damaged.
If the equipment is not used immediately, replace the protective covers. Store the
equipment in suitable conditions.
Intended use
☞ The pump and all system parts must not be used on humans or animals.
☞ Prevent any part of the human body from coming in contact with vacuum.
☞ Ensure that the individual components are only connected, combined and oper-
ated according to their design and as indicated in the instructions for use.
☞ Comply with notes on correct vacuum and electrical connections, see section
”Use and operation”.
• The pumps are designed for ambient temperatures during operation between
+10°C and +40°C. Check the maximum temperatures especially if installing the
pump in a cabinet or a housing and make sure ventilation is adequate. Install an
external automatic ventilation system if necessary. If pumping hot process gases
make sure that the maximum permitted gas inlet temperature, which depends on
several parameters like inlet pressure or ambient temperature (see ”Technical
data”), is not exceeded.
• Particles and dust must not be aspirated.
Use the equipment for the intended use only, i.e. for generation, control and meas-
urement of vacuum in vessels designed for that purpose.
Setting up and installing the equipment
➨ Equipment must be connected only to a suitably fused and protected electri-
cal supply and a suitable earth point. Failure to connect the motor to ground may
result in deadly electrical shock.
The mains cable may be fitted with a moulded European IEC plug or a plug suit-
able for your local electrical supply. If the plug has been removed or has to be
removed, the cable will contain wires colour coded as follows: green or green and
yellow: earth; blue or white: neutral; brown or black: live.
☞ Due to the high compression ratio of the pump, the pressure at the outlet port
might get higher than the maximum permissible pressure compatible with the
mechanical stability of the system.
☞ Do not permit any uncontrolled pressurizing (e. g. make sure that the exhaust
pipeline cannot become blocked). If there is an exhaust isolation valve, make
sure that you cannot operate the equipment with the valve closed. Risk of burst-
ing!
☞ Always provide a free and pressureless exhaust pipeline.
☞ Max. permitted pressure at the pressure transducer: 1.5 bar (absolute).
☞ Ensure that the system design does not allow the coolant outlet pipeline to be-
come blocked.
