Installation and Operation

5.4 General References
CAUTION!
On continuous operation it’s recommended to run the pump below 10mbar maximum vacuum
pressure.
According to its intended use the capacity of the vacuum pump depends on:

the kind of assembly

accessories

the oil used

additional connections

vacuum piping system
In addition, fail-safe operation is determined by the mode of maintenance. Elements such as valves,
filters, condensers should be provided as early as in the conception. The materials of the vacuum
piping should be selected in such a way that they will be resistant to the media to be delivered!
5.5 Installation and Connection
1. Set the rotary vane pump on a flat and horizontal surface. If more rigid mounting is required,
bolt the pump base to the surface. See chapter 5.2 Pump Mounting.
2. Remove the clamping ring and the protection cap of the suction and exhaust ports.
3. Attach the vacuum connection to the suction port and the exhaust pipe on the exhaust port.
The suction and pressure ports must not be connected the wrong way round by mistake!
WARNING!
Never block or impede air flow from the exhaust port. High pressure can build up
within the oil reservoir if the exhaust port is blocked. Check frequently, especially if
exhaust is piped out of the building.
WARNING!
Consider the warning reference on the terminal box of the motor!
4. Recheck the oil level. If needed refill oil
– see chapter 6.3.2 Filling up with Oil. Please note
that the pumps are delivered without oil filling. Initial oil filling must be done by the user.
5. Connect the rotary vane pump to the electrical supply. Please note the explanations on
chapter 5.5.1 Connection to the Electric S.
6. How to operate the pump see chapter 5.6 Starting-up.
