6. Installation and connection
Only install and operate the pumps under the operating parameters
and conditions 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. Mount accessory parts filter or silencer (if present).
If the pump is used as a vacuum pump, mount a silencer at the
pressure side if necessary. If the pump is used as compressor,
mount a filter at the suction side if necessary.
Before mounting the filter or silencer, unscrew the correspond-
ing hose connector from the threads in the pump head.
3. Connect the suction line and pressure line (N 86 K_.18: tube
ID 4 mm; N 811 K_.18: tube ID 6 mm).
4. Lay the suction and pressure line at a downward angle to
prevent condensate from running into the pump.
5. Insert the power cable’s plug into a properly installed
shockproof socket.
