Remove all packing material, remove the product from its packing-box, remove pro-
tective covers from inlet and outlet ports and keep them. 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.
☞ Read and obey this manual before installing or operating the equipment.
Use the equipment for the intended use only, i. e. for generation of vacuum.
☞ Prevent any part of the human body from coming in contact with the vacuum.
☞ Obey notes on correct vacuum and electrical connections.
☞ Adopt suitable measures to avoid that liquids flow on or into the pump motor when
assembling or disassembling vacuum connections at the pump. Risk of corrosion
and/or short circuit!
☞ Take care when connecting and deconnecting the vacuum tube.
☞ Make sure that the individual components are only connected, combined and op-
erated according to their design and as indicated in the instructions for use.
Obey national safety regulations and safety requirements concerning the use of
vacuum and electrical equipment.
☞ Ensure that the equipment is suitable for the intended operation.
☞ 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.
Attention: Flexible elements tend to shrink when evacuated.
The main on/off switch is located sidewise at the terminal box.
☞ Equipment must be connected only to a suitable fused and protected electrical
supply and a suitable earth point (recommended slow-blow fuse 0.85 A for 230 V).
Failure to connect the motor to ground may result in deadly electrical shock.
☞ The supply 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.
☞ Check that mains voltage and current conform with the equipment (see rating plate).
Direction of rotation of pumps with three phase motor: Pumps wired ready for
connection with three phase motor are supplied with a mains plug. The electrical
wiring is laid out for a right-handed rotary field.
Checking the direction of rotation:
Switch on pump for a few seconds and check if the pump sucks at inlet. If no
suction occurs switch of pump immediately. The three phase socket has to be
checked and if necessary corrected by an electrician.
☞ If the equipment is brought from cold environment into a room for operation, allow
the equipment to warm up (pay attention to water condensation on cold surfaces).
☞ Ensure that installation is in compliance with limitations from the degree of protec-
tion, see section ”Technical Data”.
Do not permit any uncontrolled pressurizing (e. g. make sure that the exhaust pipe-
line cannot get blocked). If you have an exhaust-isolation valve, make sure that you
cannot operate the equipment with the valve closed. Risk of bursting!
☞ Ensure that the system design does not allow the exhaust pipeline to get blocked.
☞ Avoid overpressure of more than 0.2 bar in case inert gas is connected.
☞ The diameter of the inlet and outlet pipeline should be at the least as large as the
diameter of the pump connection pipelines.
