3 Scope of delivery and installation
You will have purchased your system with or without
the option of commissioning by Genevac personnel
and possibly, without the option of a Genevac
vacuum pump and condenser.
Reference will be made in the following notes to the
installation procedures required to cover these
options.
On delivery, it is advisable to unpack your system at
the point of receipt, to ease the movement of the
component parts to the point of use.
3.1 Checking the delivery
Check the contents of the delivery as soon as
possible against the delivery note and notify
Genevac Ltd immediately of any missing or
damaged parts. (Refer to section 10 for contact
details).
3.2 Arranging commissioning
If your system is to be delivered separately, Genevac
Ltd will contact you prior to the delivery, to agree a
date to commission your system.
3.3 Training
Commissioning will normally include training in the
basic operation of the System. Further in house
training is recommended to fully exploit the flexibility
of the system.
THE HT-8/HT-12 EVAPORATOR MUST NOT BE
OPERATED BY PERSONNEL WHO LACK THE
TRAINING OR PROFESSIONAL EXPERIENCE TO
COMPREHEND THE HAZARDS THAT CAN ARISE
WHEN USING THE SYSTEM.
Personnel without such training require thorough
instruction. These operating instructions should form
the basis of this instruction.
3.4 Positioning the evaporator
POSITION THE EVAPORATOR AT LEAST 300 MM
AWAY FROM THE EDGE OF A BENCH AND THE
SAME DISTANCE CLEAR OF BREAKABLE
OBJECTS OR AREAS WHERE ENTRAPMENT
COULD OCCUR.

Genevac HT-8 & HT-12 Series II Evaporating Systems
04-4541 Issue 1-9 – June 2008 Page 9 of 64
IF THIS POSITIONING REQUIREMENT IS
IMPRACTICAL THEN THE EVAPORATOR
SHOULD BE BOLTED TO THE BENCH OR
TROLLEY, BY ITS FIVE MOUNTING FEET, USING
M10 H.T. BOLTS ZINC.
GENEVAC SHOULD BE CONSULTED FOR
ADVISE ON ANY OTHER POSITIONAL
REQUIREMENTS.
3.5 Fitting the vacuum
pump
One of the following pumps will
have been supplied with your
system:
Scroll:
The Scroll pump supplied by
Genevac is only available as a
Non Recirculating model.
CVP:
The CVP 100 pump as
previously supplied by Genevac
was available in two formats:
the standard (Non
Recirculating) model or the
optional Recirculating model.
General
The Genevac pump supplied
with your evaporator will have
the connecting pipe/pipes,
fittings and power control lead
included with it.
Connect your vacuum pump to
the evaporator using the
connecting pipe and flange
fittings.
Connect the power and control
lead between the pump and the
socket on the rear of the
chamber.
If your system has been supplied with a Scroll pump then it must not be moved
between systems without first consulting Genevac Service for advise.
The Scroll pump will only function correctly on a Genevac Evaporator that has
been upgraded to work with the Scroll pump.
If your system has been supplied with a CVP pump then it must have an adequate supply of cooling
air and the hot outlet must have at least 300 mm of space beyond the hot air grille in the pump base.
It should not be placed in a cupboard without special precautions to ensure adequate cooling.
Consult Genevac Service for advice in such cases.

4 Safety
BEFORE OPERATING THE SYSTEM, IT IS
IMPORTANT THAT THE FOLLOWING NOTES ARE
READ TO ENSURE THAT THE IMPLICATIONS TO
THE SAFETY OF PERSONNEL OPERATING THE
SYSTEM AND FOR THE PROTECTION OF SAMPLE
INTEGRITY ARE UNDERSTOOD.
Samples in the chamber are subjected to
accelerations of up to 500G with a maximum load
capacity of 1.5 kg per swing.
The following precautions should therefore always be
observed.
4.1 Safe loading of rotor
Never exceed the maximum load capacity of 1.5 kg
per swing.
Balance pairs of sample holders that are loaded
opposite each other to within 10g (approximately).
Locate tubes correctly in tube holders.
Locate sample blocks correctly in sample swings.
Load two or four tube holders in opposite and
balanced configurations.
Distribute tubes in sample holders symmetrically.
Rotate the rotor by hand after loading and check that
all tube holders and plates are correctly located before
starting a run and before re-starting an interrupted run.
Do not load tubes or vials into sample holders other
than those types that have been approved by
Genevac Ltd.
Do not use sample holders that have not been
supplied with system without consulting Genevac
Service.

4.2 Safe loading of rotor – General Document
Genevac are obliged to include the following information in its entirety, irrespective of the system type.
As with a centrifuge, a Genevac centrifugal evaporator must be loaded correctly to remove risk of damage.
Failure to correctly load a system can lead to loss of samples, system damage and significant downtime. This
guide is intended for new users and also as a reminder for more experienced users. The principles outlined
apply to all Genevac evaporators.
The document deals with various aspects of loading:
•Use of correct swings and sample holders
•Observation of weight limits
•Safe loading of sample holders into swings
•Balancing of swings and sample holders
•Good procedural practice
Nomenclature
Firstly, it is important to understand what is meant by some of the terms that will be used in this document.
Most Genevac systems feature “swung” rotors.
(Some, however, feature “fixed” rotors, with many angled holes for individual tubes. But this document
however is primarily concerned with swung rotors).
A swung rotor includes a swing or bucket. Below are drawings of typical swings for HT systems.
Open (or standard) Side-Bridge Fast-StackTM
(for microtitre plates)
Each of these swing types lifts straight out of the rotor. On large Mega systems, however (not shown here) the
swings are generally fixed in place and cannot be lifted out. Which swing is ideal depends on which sample
holder is required.
There is a large range of sample holders which sit in the swings, into which tubes, vials, beakers or flasks are
loaded.
Use of Correct Accessories
Genevac supply a wide range of sample holders to cover a variety of plate, tube, vial or flask formats. Where
no holder is available, custom units can be made. In a few cases worldwide, users have developed their own
holders and have collaborated with the Genevac R&D department to ensure the holders are suitable and
approved for use.
Important properties for a sample holder include:
•Mass within prescribed maximum limit.
•Closely matched mass within a set of holders.
•Correct centre of gravity.
•Good thermal conductivity.
•Correct hole form and size tolerance to prevent tube or vial breakage under centrifugal force.
All Genevac holders are designed with these constraints in mind. Other 3rd party accessories may not be.
Generally, apart from microtitre plates, users are advised not to load non-Genevac holders into a system
without first checking with Genevac.
It is important that the swings and holders used are suitable for the Genevac system in use. For example,
there are some sample holders on sale for the Series II system that might appear to fit in a Series I system but
which would exceed the weight limitations. (See next section). If in doubt always ask Genevac before running
the system.
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

Genevac HT-8 & HT-12 Series II Evaporating Systems
Page 12 of 64 04-4541 Issue 1-9 – June 2008
There are also instances where a sample holder which is perfectly satisfactory (for the tube or vial it is intended
for) becomes unsuitable if used with something else, even though it might appear that the alternative tube fits
O.K. The Genevac Accessories Brochure indicates for each holder the maximum tube length that the holder is
designed to take, and these limits should always be adhered to. (It is available from the website,
http://www.genevac.com/brochure/GenevacAccessories.pdf)
Similarly some sample holders are intended for use in a Side-Bridge swing only, not in an Open swing, even
though they might appear to fit in the latter. The Accessories Brochure has a note “For use in Side-Bridge
Swing” by these items, but if in doubt, ask Genevac.
Some users wish to run Genevac systems using the “Bohdan Miniblock” system as their sample holder. Please
note, some (not all) of this range of items significantly exceed the mass limitations of a Genevac system. If you
plan to use Bohdan Miniblocks in a Genevac system, please contact Genevac for a list of the relevant weights.
Adherence to Mass Limit
There is a maximum mass that can be loaded onto each position of a Genevac swung rotor, this total includes:
•The swing
•The sample holder
•The tubes or vials
•The sample solutions
Under no circumstances should this be exceeded.
If in doubt what your combined mass total is, load up a full swing and weigh it.
In most cases, with normal solvent volumes, any sample holder currently on sale from Genevac will fall within
the mass limit for a Series II system.
Safe loading of sample holders into swings
Applicable where both Series I and Series II evaporators are being used within the same laboratory.
There are two ways that it is possible to misload a sample holder into a swing.
One (shown below) is to rotate the sample holder such that it rests on the edges of the swing.
Incorrect – Sample Holder rotated
Correct – Sample Holder well seated
Another mode of misloading is illustrated below.
Incorrect – Sample Holder on edge of swing
Correct
Both these modes of misloading are possible with an older version of the Open or standard swing but are
virtually impossible with the new design of swing, all Series II systems feature the new design of swing. The
following illustration shows the difference.
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

Genevac HT-8 & HT-12 Series II Evaporating Systems
04-4541 Issue 1-9 – June 2008 Page 13 of 64
Series I vs Series II Swings:
The older Series I design is easy to distinguish
because the corners are not welded.
The newer (“Series II“) swing has angled sides
that make the incorrect loading illustrated
above virtually impossible. Care still has to be
taken though.
It also has rounded and welded corners.
Genevac offer a low cost upgrade to any user who has the old type of swing and who wishes to avoid the
possibility of this misloading ever occurring
Balancing of swings and sample holders.
Opposite pairs of swings need to be balanced within specification and that the swings are of the same type and
version. Please note that there are several versions of Side Bridge Swings in circulation with a static weight
ranging from 375g to 445g. Ensure that swings of the same static weight are positioned diametrically opposite
in the rotor; ideally use the same version of swings in all four position of each rotor. Genevac systems have
some inbuilt tolerance for imbalance and a system for shutting off if the out-of- balance is unacceptably high but
it is advised that the user aims for no more than 10g imbalance between opposite pairs of swings.
Where it is necessary to make “dummy” samples to balance real loads, the balancing load should be of a
similar solvent composition. For example, do not balance 200g of 50/50 Water/Acetonitrile with 200g of water,
because partway through the run, when the acetonitrile has all gone but the water has barely started
evaporating, the system would be 100g imbalanced.
Note that with a system such as the Fast-StackTM swing, balancing is slightly more complex. Suppose a “Fast-
StackTM Deepwell” swing is used with two 96 well microtitre plates, 2ml per well. (The Fast-StackTM swing is
illustrated on the first page of this document). In one swing, the lower microtitre plate is empty, the upper
microtitre plate is full, 1.8mls per well. On the other swing, the reverse is true.
The two swings now weigh the same, but if
placed opposite each other in a system, would
not be balanced, because when the swings
rotated to their operating attitude, the centre
of mass of one is at a different radius to that
of the other.
This effect becomes very significant when balancing multi level swings in large Mega systems.
It is also preferable not to run with only two swings out of four present on any one level of the rotor. If there are
only two swings’ worth of samples, you should still load swings and empty sample holders in the other
positions. This ensures the rotor is evenly loaded.

Good procedural practice
Finally, there are a few general rules for safe operation of a system:
•Ensure only users familiar with all the issues outlined in this document are permitted to operate the
equipment.
•Only load swings and sample holders approved by Genevac.
•System should be loaded and started by the same person.
•Never leave system unevenly loaded and close the door. Someone may start it.
•Never start, or restart a system without checking it is evenly loaded, all sample holders are correctly seated,
all swings are swinging freely.
•Refer to SampleGuard - Probe Positions document available at:
http://www.genevac.com/applications/downloads1.html
for correct use of Sample Guard Probes.
Misloading may result in damage to samples and the machine, and could void the warranty.

4.3 Safe door operation
The door is opened and closed manually but locked
automatically by an electric actuator.
Close and hold the door firmly against the door seal
and press and hold the Door Close switch.
A single audible beep indicates that the door is
locked and it is safe to proceed.
A proximity switch will prevent the mechanism from
locking if the door is not closed.
Hold the door firmly against the door seal whilst
holding down the Close Door switch.
Note that the door mechanism will NOT work if the
condenser is not connected to the system.
4.4 Limitations of use
Your HT-8/HT-12 Series II evaporating system is
unsuitable for use under the following
circumstances.
•With strong mineral acids such as HCl and HBr
at all concentrations, unless specifically built to
order.
•EVAPORATING DIETHYL ETHER AND
OTHER SIMILAR LOW FLASH POINT
SOLVENTS WITHOUT A GENEVAC INERT

5 Getting started
The following notes describe the basic start up, set
up and run instructions for your HT-8/HT-12
evaporating system.
When the Genevac vacuum pump is fitted, the
chamber is powered from the pump and so it is only
necessary to connect the pump to a suitable mains
power supply.
