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,

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).

The SCC 950 vacuum pump system uses a pump to generate a
vacuum with which two separate processes can be controlled with
the help of the two hand terminals (Fig. 2/4and 13, p. 13) or a PC.
The control module (15) contains two vacuum (17 and 18) and two
ventilation connections (16 and 19). Integrated non-return valves in
the vacuum connections stop the two processes from affecting
each other. The integrated pressure sensors each determine the
current process pressure.
Collection flask (9) collects on the suction side of the pump parti-
cles and drops that were, contrary to the requirements of the
pump, suctioned from the vacuum chamber. The collection flask is
coated (implosion protection) and fastened to the vacuum pump
system via a flask clip (7).
The high-performance condenser (3) at the pump outlet recovers
solvent from the transferred gas instead of allowing it to get into the
environment or the fume hood. The high-performance condenser is
surrounded by a shell for temperature insulation and explosion
protection.
Solvents separated in the high-performance condenser are collect-
ed in the collection flask (8), which is coated for explosion protec-
tion. A flask clip (7) fastens the glass flask to the condenser flange.
A recirculating cooler or continuously flowing cold water (or another
cooling medium) cools the high-performance condenser to the
condensation temperature.
The charging station (12) is enclosed with the delivery and can
simply be placed next to the vacuum pump system. It is used to
charge hand terminal 2 (13) when hand terminal 1 (4) is on the
vacuum pump system. If required, it can also be fixed to the vacu-
um pump system with the enclosed bracket (see Chapter 6.1, p.
19ff).
5.1.2. Vacuum pump system functions
The vacuum pump system can be operated in four different modes:
Evacuate
The vacuum pump system evacuates a vacuum chamber
with adjustable pump capacity.
Pressure Control
The vacuum pump system controls the system pressure to
the selected value (constant pressure).
Automatic
The vacuum system independently finds the sample's va-
por pressure and adjusts the process pressure according-
ly.
In operating mode "Automatic" only one active process
can
be operated at a time. A possible second process
can only
be started after ending the first process.

Vacuum pump system SCC 950 Assembly and functions
Translation of original Operating Instructions, English, KNF 304771-304773 07/18 15
Function
The vacuum system controls the pressure according to the
entered pressure curve. Up to 10 different pressure curves
can be stored. The following process parameters can be
entered:
−Setpoint pressure at various times after starting the pro-
cess
−Coolant valve (accessory) ON and OFF with point in time
after start of process
−Option "Jump" with time after the start of the process:
The system evacuates/ventilates to the required pressure
as quickly as possible.
−Option "Automatic" with time after the start of the process:
Automatic detection of the boiling pressure
If the set limit pressure is reached without a vapor pres-
sure, the program goes to the next function step.
−Option "Automatic Plus" with time after the start of the pro-
cess:
Automatic detection of the vapor pressure with subsequent
pressure reduction.
If one of the two options "Automatic " or "Automatic Plus" is
set,
again only one active process can be operated on the
vacuum pump system.
At any time during an active process, you can switch to manual
process control. Functions for evacuation and pressure control
are available simultaneously. When activating manual process
control, the current actual pressure will be adopted as the first
setpoint pressure. In other words, process pressure will be initially
"frozen" at the current value.
For smart process control, the modes of operation can be com-
bined as you wish. For example, after boiling point detection in
automatic mode, the following modes of operation can be used to
specifically distill the solvent off:
Evacuate
(constant rate of evaporation for optimum utilization of the
condenser)
Function
(operation at a specified pressure ramp to achieve separa-
tion of higher boiling components)
Manual process control
(active control of the distillation via the setpoint pressure)
To change to a different operating mode, the process is stopped
and then restarted in the new mode.
The gas ballast switch (Fig. 2/6) can be used to open and close the
gas ballast valve on the vacuum pump system's pump (see Chap-
ter 5.3).

To distinguish between the two hand terminals, the rotary knob
(Fig. 3/5) is marked 1 or 2.
Hand terminal 1 controls process 1 and hand terminal 2 con-
trols process 2.
Function
The hand terminals are used to set the process parameters of the
two processes with which the SCC 950 vacuum pump system
controls the pressure.
Settings can be made on the hand terminal's touchscreen (2) or
with the rotary knob (5).
Hand terminal 1 can be removed from the bracket on the vacuum
pump system (see Chapter 5.1.1, page 13) and the vacuum pump
system can be operated wirelessly. This provides a convenient
way to operate the vacuum pump system when it is in a cabinet or
under a closed fume hood.
Hand terminal 2 can also be used for wireless operation of the
vacuum pump system. It is packed loosely along with the other
components and can, if required, be placed on the enclosed charg-
ing station.
If a hand terminal is in the bracket on the vacuum pump system
when it is switched on or on the charging station and this is con-
nected to the mains supply via the supplied power supply unit, the
hand terminal batteries are charged automatically. The batteries
will charge even if the hand terminal is switched off. Alternatively,
the batteries can be charged through the hand terminal's power
supply (see mains socket (4) on the hand terminal). This eliminates
the need for the vacuum pump system to be positioned where it is
accessible for the user.

The power supply also makes it possible to supply the hand termi-
nal with electrical power directly from a mains.
A signal sound on the hand terminal will indicate when the batter-
ies are nearly drained.

How diaphragm pumps work
Diaphragm pumps transfer, compress (depending on pump ver-
sion), and evacuate gases and vapors.
The elastic diaphragm (4) is moved up and down by the cam (5)
and the connecting rod (6). In the downward movement, the dia-
phragm sucks in the gas to be transferred via the inlet valve (2)
and in the upward movement, it presses it out of the pump head
via the outlet valve (1). The diaphragm hermetically seals the
pumping chamber (3) from the pump drive (7).

Connect the vacuum pump system only 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, allow the vacuum pump system to reach
ambient temperature at the installation location.
Install the vacuum pump system so that the two fans are not
blocked.
Make sure that the installation location is dry and that 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 from dust.
Protect the vacuum pump system from vibration and impact.
Only connect components to the vacuum pump system that
are designed for the pneumatic data of the vacuum pump sys-
tem (see Chapter 4, page 9).
A recirculating cooler or flowing cold water (or another cooling
medium) is needed to cool the high-performance condenser to the
condensation temperature.
Hand terminal 1 of the SCC 950 vacuum pump system is secured
at the factory in order to prevent damage during transportation.
The transportation safeguard must be disengaged before the hand
terminal can be removed. To do this, rotate the knurled knob (Fig.
2/2, page 13) out until the hand terminal can be removed.
The transportation safeguard can be screwed back in before
tr
ansporting the vacuum pump system in the future.
Install the separately included collection flasks (Fig. 2/8and 9,
page 13) using the included flask clips (Fig. 2/7, page 13).
Set up the charging station for hand terminal 2 (see Fig.
6, page 20).
Basically, there are four different setup or installation options:
