6. Installation and connection
Only install the pumps under the operating parameters and condi-
tions described in chapter 4, Technical data.
Observe the safety precautions (see chapter 3).
6.1. Installation
Before installation, store the pump at the installation location to
bring it up to room temperature.
See chapter 4, Technical data, for the dimensions of pump.
Install the pump so that the motor fan can intake sufficient
cooling air.
Make sure that the installation location is dry and the pump is
protected against rain, splash, hose and drip water.
Choose a safe location (flat surface) for the pump.
Protect the pump from dust.
Protect the pump from vibration and jolt.
6.2. Connection
Only connect components to the pump which are designed for
the pneumatic data of the pump (see chapter 4).
If the pump is used as a vacuum pump, safely discharge the
pump exhaust at the pump’s pneumatic outlet.
A marking on the pump head shows the direction of flow.
1. Remove the protective plugs from the pneumatic connectors of
the pump.
2. Connect the suction line and pressure line.
3. Lay the suction and pressure line at a downward angle to
prevent condensate from running into the pump.
4. If necessary, use the interface cable to connect the pump with
the vacuum controller VC 900 (Fig. 2/
6
, see Chapter 10.2
Accessories
for interface cable). Further information on con-
necting see operating instructions VC 900.
5.
Insert the power cable’s plug into a properly installed
shockproof socket.
