1 Safety information
1.1 General information
+ Read and comply with this manual before installing or operating the equip-
ment.
• Use the mounted handle when moving the pump.
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.
1.2 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 into 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 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 sev-
eral 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 of vacuum in ves-
sels designed for that purpose.
1.3 Setting up and installing the equipment
➨ Equipment must be connected only to a suitable electrical supply and a suit-
able earth point. Failure to connect the motor to ground may result in deadly
electrical shock.
+ Due to the high compression ratio of the pumps, pressure at the outlet port might
be generated being 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 bursting!
+ Check the overpressure safety relief device at the exhaust waste vapor con-
denser in appropriate intervals.
+ Always provide a free and pressureless exhaust pipeline.
• Provide a firm level platform for the equipment and check that the system to be
evacuated is mechanically stable and that all fittings are secure. Ensure a stable
position of the pump without any mechanical contact except of the pump feet.
Comply with all applicable safety regulations.
