Translation of original Operating Instructions, English, KNF 125549-125552 07/18 25
6. Installation and connection

Always install the vacuum pump system under the operating
parameters and conditions described in chapter
4
, Technical
data, page 9).

Observe the safety precautions (see chapter 3, page 7).
6.1. Installation

Before installation, store the vacuum pump system at the
installation location to bring it up to room temperature.

Install the vacuum pump system so that the two motor fans of
the vacuum pump system are not blocked.

Make sure that the installation location is dry and the vacuum
pump system is protected against water in the form of rain,
spray, splashes and drips.

Choose a safe location (flat surface) for the vacuum pump
system.

Protect the vacuum pump system against dust.

Protect the vacuum pump system against vibrations and jolts.

Only connect components to the vacuum pump system which
are designed for the pneumatic data of the vacuum pump sys-
tem (see chapter 4, page 9).
Only SC/SEM/SH 950:
A recirculating cooler or flowing cold water (or another cooling
media) is needed to cool the high-performance condenser to the
condensation temperature.
Only SC 950:
The hand terminal of the vacuum pump system SC 950 is fastened
in place at the factory, to prevent damage during transport. To
remove the hand terminal, it is first necessary to release the
transport fastener. To do this, rotate the knurled knob (Fig. 2/
2 , p.
13) out until the hand terminal can be removed.
The transport fastener can be screwed in again for any future
transport operations.
Install the collection flasks (Fig. 2/ 8 and 9 , p. 13 or Fig. 4/ 6 and 7 , p.
17, Fig. 5/ 6 and 7 , p. 19 and Fig. 6/ 5 and 6 , p. 21) with the flask
clips (Fig. 2/ 7 , p. 13 or Fig. 4/ 5 , p. 17, Fig. 5/ 5 , p. 19 and Fig. 6/ 4 , p.
21). The flasks and clips are included as loose parts.
