2 Product overview
2-1 Application
WARNING
Never attempt to modify the product.
Operate the unit for the specified purpose
only.
An electric shock or a malfunction may result if
the product is modified or used for any
purposes other than that specified.
This vacuum pump is a depressurizing unit for a
condensation unit including a rotary evaporator,
a test tube evaporator or a centrifugal evaporator,
a vacuum drying unit or a suction filter.
Never install the unit in a dangerous atmosphere.
Connect pipes as instructed.
※This product employs anti-corrosion parts,
which does not necessarily mean it withstands all
types of solvents.
Depending on the solvent or the operating
conditions, the diaphragm, the valves or the
suction/discharge nozzles might degrade and lead
to compromised depressurizing capacity.
When this is suspected, install a solvent collector
such as a cooling trap between the depressurizing
container and the vacuum pump and operate for
about five minutes without any load to suction air
for cleaning.
Replacement of the diaphragm and the valves
require adjustment. Ask your dealer or nearest
service center for such work.
