Until the pump is put back in to service again, the pump should be stored in
a dry place, preferably at room temperature (20 °C) but not below 0°C. Before
taking the pump out of service, it should be properly disconnected from the
vacuum system, purged with dry nitrogen and oil should be exchanged too. The
inlet and exhaust ports of the pump must be blanked off using the shipping
seals which are included upon delivery of the pump. The gas ballast must be
closed and if the pump is to be shelved for a longer period of time it should be
sealed in a plastic bag together with a desiccant (Silicagel).
If the pump has been shelved for more than one year, standard maintenance
must be run and oil must be exchanged too before the pump is put into service
again. We recommend that you contact the service from Oerlikon Leybold
Vacuum.

Operation
2.1
Installation
It is essential to observe the following instructions step by step to ensure a safe
start-up. Start-up may only be conducted by trained specialists.
The SOGEVACs can be set up on any flat, horizontal surface. Under the four feet,
there are metric threaded holes for securing the pump.
The oil level cannot be read properly if the pump is tilted. Pump risks to run
dry. The ambient temperature should be between 12°C (55°F) and 40°C (104°F)
depending on oil type. By modifying the pump or changing the oil type, the
pump can be run at a lower ambient temperature. Please consult us about this.
To ensure adequate cooling of the pump, leave enough space at the air intake
and exhaust points, so as for access and maintenance. Make sure to keep the air
intake of motor clear.
2.2
Connection to system
The standard pump is not suitable for installation in explosion hazard areas.
Please contact us, when you are planning such an application. Before installing
the pump you must reliably disconnect it from the electrical power supply
and prevent the pump from running up inadvertently. The pump must only be
installed by suitably qualified and trained personnel.
Observe all safety regulations.
