2.4 Start-up
Oil for the first filling is supplied with the pump.
Before switching on, always make sure that the pump contains enough oil.
The normal oil level is in the middle of sight glass.
If oil has to be added, unscrew the oil-fill plug, add oil and screw the plug
firmly back in.
The SOGEVAC is designed for normal startup at temperatures over 0°C (32°F)
(as per PNEUROP), depending on used oils.
To avoid overloading the motor, do not start the pump more than six
times within one hour. If frequent starts are needed, the pump should run
continuously and be linked to the vacuum vessel by means of a valve. In
that case, regulation will be made by the valve and not by start/stop of the
pump. With the valve closed, the pump consumes little energy.
-Before starting the pump ensure that the attached accessories meet the
requirements of your application and that safe operation is ensured.
-Never expose part of the body to the vacuum.There is a danger of injury.
Never operate the pump with an open and thus accessible inlet. Vacuum
connections as well as oil filling and oil draining openings must not be
opened during operation of the pump.
-The safety regulations which apply to the specific application in each case
must be observed. This applies in particular to installation, operation and
maintenance (servicing) as well as waste disposal and transportation.
Do not lay the hand on the intake to check vacuum.
Exposure of a part of the body to the vacuum result in a rush of blood in the
exposed part.
2.5 Operation
The SOGEVAC can pump gases and vapors, provided that the gas ballast
valve is installed and open and the pump has reached its operating
temperature.
Contact Oerlikon Leybold Vacuum for important safety instructions before
pumping greater than atmospheric concentrations of oxygen or other
highly reactive gases. The pump must be degreased, modified, and special
inert oil must be used for pumping oxygen. Also ATEX variants are available
for pumping explosive gases.
The motor manufacturer guarantees a maximum of 6 starts per hour. To
avoid exceeding 6 starts per hour, run the pump continuously and regulate
the vacuum in your system with a pilot valve.
Pump in operation is hot and some surfaces could reach a temperature
higher than 80°C (176°F). There is a risk of burn by touching. Take note of
warning labels on the pump.
