3 Product description
3.1 Description of function
The Vacuum Pump V-600 is intended for evacuating laboratory apparatus to a terminal vacuum of 1.5mbar (±1mbar). It can be operated either as a standalone device
or combined with optional accessories (see Chapter3.3 "Specifications supplied",
page16).
Once switched on, the Vacuum Pump V-600 runs in continuous mode unless it is
connected to the Interface I-300/I-300 Pro unit. In unregulated continuous mode, the
pump runs at a maximum speed of 1500 rpm and generates a terminal vacuum of
1.5mbar (±1mbar). The time required for evacuation depends on the size (volume)
of the vessel.
When operating as a standalone unit, the Vacuum Pump V-600 automatically
switches to energy saving mode after 1 hour of operation. In energy saving mode, the
Vacuum Pump V-600 runs at 80% of maximum speed but still generates the same
terminal vacuum of 1.5mbar (±1mbar). After 2 hours of operation, the speed reduces to 50% of maximum while still maintaining the same terminal vacuum.

NOTE
Users may only carry out the servicing and cleaning operations described in this section.
Any servicing and repair work which involves opening up more than the casing front
may only be carried out by authorized service technicians.
u Use only genuine BUCHI consumables and spare parts in order to ensure correct
operation of the device and preserve the warranty.
u Before carrying out any servicing work, switch off the device and disconnect it
from the power cable.
7.1 Cleaning
7.1.1 Important considerations when cleaning
WARNING
Risk of fatal injury from electric shock.
If the pump is opened up while it is running there is a risk of dangerous electric
shocks.
u Before carrying out any cleaning or servicing work, always shut down the device
and disconnect the power cable.
7.1.2 Cleaning the pump
The pump only needs to be cleaned if the terminal vacuum is no longer achieved, dirt
is visible through the inspection window or after using certain chemicals. Daily cleaning of the pump is not necessary.
u Detach tubing connections to other laboratory equipment.
u If present, remove Woulff bottle from pump intake and secondary condenser or
cold trap from pump outlet and clean them.
u Hold several paper towels in front of the pump outlet.
u Switch on the Vacuum Pump V-600 and allow it to run.
u Spray 5 to 10 mL of acetone or ethanol into the pump intake.
u Hold your finger over the pump intake for a short time so that a vacuum is created.
u Remove your finger from the pump intake again.
u Allow the pump to run until there is no more liquid inside the pump heads.
u If necessary, repeat the process of flushing with acetone/ethanol and evacuating.
u Switch off the pump and reconnect the tubing.
NOTE
If the procedure described above is insufficient, carry out the following steps:
4 Clean the casing, see Chapter7.1.3 "Cleaning the casing", page41.
4 Clean the glass components, see Chapter7.1.4 "Cleaning glass components",
page41.
