1. About this document

1.1. Use of the Operating Instructions

The Operating Instructions are an integral part of the vacuum

pump system.

Carefully study the Operating Instructions before operating the

vacuum pump system.

Always keep the Operating Instructions handy in the work

area.

Forward the Operating Instructions to any subsequent

owners of the vacuum pump system.

Customer-specific vacuum pump systems (model designations

which begin with "PJ" or "PM") may differ from the Operating

Instructions.

In the case of custom systems, take note of any additionally

agreed specifications.

Compliance with the Operating Instructions is essential for safe

and reliable operation of the vacuum pump system. Failure to

do so

may result in damage or injury.

2. Use

2.1. Intended use

The SCC 950 vacuum pump system is designed for use in chemi-

cal, pharmaceutical, and biological laboratories. It is designed

exclusively to transfer gases and vapors.

Make sure that the installation location is dry and that the system is

protected against water in the form of rain, spray, splashes and

drips.

The vacuum pump system is solely for use in indoor areas.

Owner's responsibility

Only install and operate the vacuum pump system under the

operating parameters and conditions described in Chapter 4,

Technical data.

Protect the vacuum pump system against humidity.

Before using a medium, check the compatibility of the materials of

the pump head, diaphragms, valves, seals and hoses with the

medium.

Before transferring a medium, check whether the medium can be

transferred safely.

Only transfer gases that remain stable under the pressures and

temperatures occurring in the vacuum pump system.

The high-performance condenser may be used only at the pump

outlet; there is a risk of implosion if it is used at the pump inlet.

Make sure the tubes for gas and cooling medium are correctly

assigned on the high-performance condenser. Inlets and outlets of

the gas connections must not be confused.

Laboratory equipment or additional components connected to the

vacuum pump system have to be suitable for use with the pneu-

matic capabilities of the vacuum pump system (see Chapter 4,

page 9).

2.2. Improper use

The vacuum pump system must not be operated in potentially

explosive atmospheres.

The vacuum pump system is not suitable for transferring dust.

The vacuum pump system is not suitable for transferring liquids.

The vacuum pump system must not be used if the entry of air or

gas into the vacuum pump system during venting (ventilation

valve) or an open gas ballast valve could result in the creation of

reactive, explosive or otherwise hazardous mixtures (e.g. with the

medium).

The vacuum pump system must not be used to create vacuum and

pressure simultaneously.

Never apply positive pressure to the suction side of the vacuum

pump system.

3. Safety

The vacuum pump system is built according to the generally rec-

ognized rules of technology and in accordance with the pertinent

occupational safety and accident prevention regulations. Neverthe-

less, potential dangers during use can result in injuries to the user

or others, or in damage to the vacuum pump system or other

property.

Only use the vacuum pump system in a good technical and proper

working order, in accordance with its intended use, with awareness

of safety and potential hazards, and observing the advice within

the Operating Instructions, at all times.

Make sure that only trained and instructed personnel or specially

trained personnel work on the vacuum pump system. This espe-

cially applies to assembly, connection and servicing work.

Make sure that the personnel have read and understood the Oper-

ating Instructions, especially the "Safety" chapter.

Ensure adherence to all pertinent accident prevention and safety

regulations when working on and operating the vacuum pump

system.

Do not subject parts of the body to vacuum.

Open housing parts with notice sticker (see Fig. 1) only after sepa-

rating mains plug from power source.

Ensure that personnel check before each use of the SCC 950

vacuum pump system that they have the correct hand terminal for

the vacuum pump system. The vacuum pump system is equipped

with a paging function for this purpose (see Paging the vacuum

pump system, page 34).

When transferring dangerous media, observe the safety regula-

tions for handling such media.

Be aware that the vacuum pump system is not designed to be

explosion-proof.

Make sure that the temperature of the medium is always sufficient-

ly below its ignition temperature in order to avoid ignition or explo-

sion. This also applies to unusual operating situations.

Note that the temperature of the medium increases when the pump

compresses the medium.

Hence, make sure that the temperature of the medium is sufficient-

ly below its ignition temperature, even when it is compressed to the

maximum permissible operating pressure of the vacuum pump

system. The vacuum pump system's maximum permissible operat-

ing pressure is specified in the Technical data (see Chapter 4,

page 9).

Consider any external sources of energy, such as sources of

radiation, that could additionally heat the medium.

In case of doubt, consult KNF customer service.

When ventilating the vacuum pump system with air or inert gas, be

sure to prevent the formation of reactive or explosive media. The

maximum permissible operating pressure at the ventilation connec-

tion (Fig. 2/18, p. 13) is 0.1 bar g.

All replacement parts should be properly stored and disposed of in

accordance with the applicable environmental protection regula-

tions. Ensure adherence to the pertinent national and international

regulations. This applies especially to parts contaminated with toxic

substances.

The SCC 950 vacuum pump system conforms to the Directive

2011/65/EU (RoHS2).

The SCC 950 vacuum pump system conforms to the safety regula-

tions of Directive 2014/30/EU concerning Electromagnetic Compat-

ibility and Directive 2006/42/EC concerning Machinery. The follow-

ing harmonized standards are met:

DIN EN 61010-1

DIN EN 61326-1 – Class A

DIN EN 50581

In accordance with IEC 664 the systems conforms to:

Overvoltage category II

Pollution degree 2

All repairs to the vacuum pump system must be carried out by the

responsible KNF Customer Service team.

Housings with live parts may be opened by technical personnel

only.

Use only genuine parts from KNF for servicing work.

The pump of the vacuum pump system is supplied by a univer-

sal power supply with integ

rated overload protection. It is

protected against overheating by a temperature sensor on the

motor board and equipped with overcurrent protection.

If one of these safety functions is triggered, the pump will be

shut down and must be manually reset, as fol

lows:
