CAUTION
Operation in the wrong direction of rotation, even for a short period
of time, can destroy the vacuum pump.
Prior to starting up, make sure that the vacuum pump will operate in
the proper direction of rotation.
In the case of portable installation of the vacuum pump, the electrical
connection has to be equipped with cable guides in order to prevent
undue stresses on the electrical cable.
If the direction of rotation of the fan must be changed:
u
Switch around any two of the drive motor wires in the terminal
box
Looking at the motor fan cover, the direction of rotation is clockwise.
Notes on Operation
Application
CAUTION
The vacuum pump is designed for operation under the conditions
described below.
In case of disregard, risk of damage or destruction of the vacuum
pump!
Risk of Injury!
The vacuum pump must be operated under the conditions
described below.
This vacuum pump is designed for
–
the suction (SV) or the exhaust (SD)
of
–
air and other dry, non-aggressive, non-toxic and non-explosive ga-
ses
Conveying media with a higher density than air leads to an increased
thermal and mechanical load on the vacuum pump and is permissible
only after prior consultation with Busch.
The vacuum pump is made for the intended use in potentially non-ex-
plosive areas
Max. permissible number of starts per hour: 12.
The vacuum pump is thermally suitable for continuous operation.
The vacuum pump is leak-tight at ultimate pressure.
CAUTION
This vacuum pump is a dry-running pump.
Do not lubricate the vacuum pump with oil or grease.
CAUTION
During operation the surface of the vacuum pump may reach tem-
peratures of more than 100°C.
Risk of burns!
The vacuum pump shall be protected against contact during opera-
tion. Before touching the vacuum pump, wait until it has cooled
down sufficiently or wear protective gloves.
CAUTION
Make sure that the installation space or location is vented in such a
way that sufficient cooling of the vacuum pump is warranted
CAUTION
The vacuum pump emits noise of medium intensity.
Risk of damage to the hearing.
People staying in the vicinity of a non-noise insulated vacuum pump
over extended periods sof time must wear suitable ear protection.
Seco rotary vane pumps work absolutly oil free. The vanes are made of
special carbon materials and do not need any lubrication.
l
Make sure that all provided covers, guards, and protection grids
etc. have been fitted
l
Make sure that protective devices will not be disabled.
l
Make sure that cooling air inlets and outlets are not covered or
obstructed and that the cooling air flow is not affected adversely in
any other way
l
Make sure that the “Installation Prerequisites” (see “Installation
Prerequisites and Commissioning” are complied with and will re-
main so, particularly that there is sufficient cooling at all times.
CAUTION
The SD version is equipped with an pressure relief valve (
PRV
which
has been set to the maximum pressure. This setting must not be
changed.
The vacuum pumps have a standard regulating valve.
–
Model SV: vacuum regulating valve (
VRE
)
–
Model SD: pressure regulating valve (
DV
)
During operation of the vacuum pump, the regulation of either pres-
sure or vacuum can be done at any given time. To do this, turn the
button of the relevant valve.
CAUTION
When the vacuum pump is switched off whilst still under vacuum,
gas may flow back into inlet pipe.
To avoid this, a non-return valve or shut-off valve has to be instal-
led.
Maintenance
CAUTION
Always wear protective clothing when carrying out maintenance
work.
