1. Safety Instructions
☞Read and follow all instructions in this manual.
☞Inform yourself regarding:
– Hazards which can be caused by the pump;
– Hazards which can be caused by your system.
☞Observe the safety and accident prevention regulations.
☞Regularly check that all accident prevention measures are
being complied with.
☞Do not carry out any unauthorised conversions on or alte-
rations to the unit.
☞When returning units, take note of shipping instructions in
the Section “Service”.
Danger of damage to the unit or to the system.
CAUTION
Danger of burns from touching hot parts.
☞
PLEASE NOTE
Danger of personal injury.

2.2. Versions
Condensate Separators KAS 025 ... KAS 100 are manufactured
in corrosion proof aluminium and sealed with seals of elasto-
mer.
Condensate Separators are available in the following
versions:
Standard model
Helium tight model
– Leak rate of the housing (tested): < 1 • 10-5 mbar l/s
Corrosive gas model
– Leak rate of the housing (tested): < 1 • 10-5 mbar l/s
– Sight glass manufactured in PTCFE
– Operating fluid drain screw manufactured in stainless
steel
To protect the pump against the damaging effects of conden-
sates, the fitting of a condensate separator in the intake line
of a vacuum pump is recommended.
This keeps the lubricating efficiency of the operating fluid and
ensure the attainable final pressure.
The KAS is provided with a sight glass to show the condensa-
te level.
Proper Use:
– Condensate separators cannot be cooled and cannot
therefore be used as condensers.
– As a rule, condensate separators are installed in the intake
line of a vacuum system or a vacuum pump.
– Where certain applications are involved it is also
recommended to fit a condensate separator in the exhaust
line.

3. Installation
3.1. Fitting The Condensate Separator
The condensate separator must be fitted to the intake or
exhaust side of the rotary vane pump and always be connec-
ted to the pump with flange . The connections are
designed for ISO small or ISO clamping flanges.
This permits the use of pre-fabricated standard components
in the installation; please see Pfeiffer Vacuum catalog.
Mounting on the intake side
➡Position the KAS on the flange on the intake side of the
rotary vane pump and fit using the tension ring
(accessory); take care with the centering ring on the rotary
vane pump.
X
If gases are being pumped which should not be
allowed to escape into the atmosphere an
exhaust line must be fitted.
The exhaust line should be laid so that no
excess pressure can build up in it.
CAUTION

4.1. Draining Off Condensate
Condensate must be drained when the level has risen to the
middle of the sight glass 5; this represents the maximum level.
Toxic gases and vapours can escape from the
condensate which may also become enriched
with substances harmful to health (radioactive,
chemical etc.) during the pumping of certain
media.
Condensate which has been enriched with toxic
or aggressive substances must be treated
carefully. Compliance with all relevant handling
regulations for such media is essential.
4.1.1 Intake Side Condensate Draining
To empty a condensate separator fitted on the intake side, the
valve between separator and recipient must be closed and
the vacuum pump switched off.
➡Ventilate condensate separator via ventilation screw 11.
➡Screw out drain screw 4 and allow condensate to drain
off.
➡Screw drain screw 4 and ventilation screw 11 back in;
keep an eye on O-rings 6 and 7.
➡Switch vacuum pump back on (if necessary, allow
sufficient time for the pressure in the condensate sepa-
rator to adjust to the pressure in the recipient).
➡Open valve to the recipient.
WARNING
4.1.2 Exhaust Side Condensate Draining
Emptying a condensate separator fitted on the exhaust side
can proceed without switching off the vacuum pump.
Draining the condensate is executed as described in section
4.1.1.

6. Technical Data
Do Make Use Of Our Service Facilities
In the event that repairs are necessary to your unit, a number
of options are available to you to ensure any system down
time is kept to a minimum:
– Have the unit repaired on the spot by our Pfeiffer Vacuum
Service Engineers;
– Return the individual components to the manufacturer for
repairs;
– Replace individual components with a new value
exchange units.
Local Pfeiffer Vacuum representatives can provide full
details.
Before Returning:
➡When returning the pump please use original factory
packing.
➡Dismantle all accessories.
➡Drain condensate.
➡If the pump is free of harmful substances, please attach a
clearly visible notice: “Free of contamination” (to the unit
being returned, the delivery note and accompanying
paperwork).
Harmful substances" are substances and preparations as
defined in current legislation. Pfeiffer Vacuum will carry out
the decontamination and invoice this work to you if you have
not attached this note. This also applies where the operator
does not have the facilities to carry out the decontamination
work. Units which are contaminated microbiologically, explo-
sively or radioactively cannot be accepted as a matter of
principle.
Fill Out The Contamination Declaration
➡In every case the "Contamination Declaration" must be
completed diligently and truthfully.
➡A copy of the completed declaration must accompany the
unit; any additional copies must be sent to your local Pfeif-
fer Vacuum Service Center.
Please get in touch with your local Pfeiffer Vacuum represen-
tatives if there are any questions regarding contamination.
Decontaminate units before returning or possi-
ble disposal. Do not return any units which are
microbiologically, explosively or radio-
actively contaminated.
Returning Contaminated Units
If contaminated units have to be returned for
maintenance/repair, the following instructions concerning
shipping must be followed without fail:
➡Neutralise the unit by flushing with nitrogen or dry air.
➡Seal all openings to the air.
➡Seal pump or unit in suitable protective foil.
➡Ship units only in appropriate transport containers.
Repair orders are carried out according to our
general conditions of sale and supply.
➡If repairs are necessary, please send the unit together
with a short damage description to your nearest Pfeiffer
Vacuum Service Center.
