1 Safety information
1.1 General information
☞ Read and comply with this manual before installing or operating the equip-
ment.
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.
Attention: ROTAVAC vario control / ROTAVAC vario tec are only utilizable in con-
junction with the rotary evaporator Hei-VAP Precision.
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”.

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.
 Thesupplycablemaybetted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 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!
