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
4. The pumps are factory wired for high voltage (HV) 220-240V/50Hz; 230V/60Hz.
If necessary the voltage setting can be changed to low voltage (LV) 115V/60Hz.
How to switch the mode is described in chapter 5.5.2 Change the Voltage Setting.
5. Check the AC power outlet to be sure that it is the same voltage and phase as the pump motor.
6. Recheck the oil level. If needed refill oil – see chapter 6.3.2 Filling up with Oil. Please note that
the pump are delivered without oil filling. Initial oil filling has to be done by the user.
7. Connect the rotary vane pump to the electrical supply. Please note the explanations on
chapter 5.5.1 Connecting to the Electricity Supply.
8. How to operate the pump see chapter 5.6 Starting-up.

INSTALLATION AND OPERATION
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!
