4 Description of function
This section explains the basic working principle of the Recirculating Chiller. It also shows how the
instrument is structured and provides a general functional description of its assemblies.
4.1 Functional principle
The BUCHI Recirculating Chillers are a closed-circuit cooler for use with appropriate laboratory instru-
ments. The four models are distinguished by their outputs and control. The F-100 has a fixed cooling
temperature without display. The models F-105 to F-114 are equipped with a control unit and built
in display to regulate and indicate the actual and set value of the cooling temperature. The F-100 is
optimal for cooling one BUCHI Rotavapor system. The F-114 is sufficient for cooling up to two small
to medium Rotavapor systems (e.g. R-210).

F-100 / F-105 Operation Manual, Version C
5 Putting into operation
This section describes how the instrument has to be installed. It also gives instructions for the initial
startup.
NOTE
Inspect the instrument for damage during unpacking. If necessary, prepare a status report imme-
diately and inform customer and your local BUCHI representative. Keep the original packaging for
future transportation.
Also adhere to all instructions concerning transport as described in section 9.1, Storage and trans-
port.
To move the instrument use the handle (as described in section 6.1, Operating controls and housing),
slightly lift the side of the instrument with the fix anti-slip foots and pull the instrument carefully by the
rollers.
5.1 Installation site
!DANGER
Death or serious injuries when used in explosive environments.
• Do not store or operate the instrument in explosive environments
• Remove all sources of ammable vapors
• Do not store chemicals in the vicinity of the device
Put the instrument onto a clean, stable and horizontal surface. Consider the maximum product dimen-
sions and weight. Obtain the environmental conditions as described in section 3.1, technical data.
Installation pre-requisites and installation steps:
• Do not place any objects in front of or behind the instrument.
• The instrument must have a clearance of 40cm between itself and the wall, both in front and
behind (sufficient cooling).
• Do not place containers, chemicals or other items behind the instrument.
• Do not place anything on top of the Recirculating Chiller.
NOTE
• After transport, wait at least 2 hours before switching on the chiller! Within this time the refrigerant
gathers in the compressor, avoiding damage of the compressor.
• To ensure that the power can be cut by unplugging in case of an emergency, the mains plug must
not be blocked by the instruments or any other items!
• Depending on the environmental conditions, condensation water at the cooling tubes and all other
cold surfaces of the instruments can collect!

5 Putting into operation
16
F-100 / F-105 Operation Manual, Version C
!WARNING
Stumbling or falling due to improper installation of the cables and hoses.
• The length of the cables and hoses should be kept as short as possible
• Absorb condensate water from tubes and all other cold surfaces
• If possible, avoid installing cables and hoses in aisle areas
• If installation of cables and hoses in aisle areas is unavoidable, use an adequate protective
pad in order to avoid the danger of stumbling and damage
!WARNING
Fire hazard, damage to the instrument through overheating due to inadequate air circulation.
• Do not cover the instrument
• Minimum distance from other objects must be at least 40cm
!CAUTION
Risk of minor or moderate injury due to the heavy weight of the instrument.
• Do not drop the instrument or its transport box
• Place the instrument on a stable, even and vibration-free surface
• Keep limbs out of crushing zone
!CAUTION
Danger from falling objects due to inadequate stability.
• Do not place other objects or instruments on the Chiller

F-100 / F-105 Operation Manual, Version C
5.2 Electrical connections
Notice
Risk of instrument damage if mains supply is incorrect.
• External mains supply must meet the voltage given on the type plate
• Check for proper grounding
• Exchange defective cabling immediately
After the installation procedure has been completed successfully, the power plug of the Recirculating
Chiller can be connected to mains.
The used mains circuit has to:
• provide the voltage that is given on the type plate of the instrument.
• be able to handle the load of the connected instruments.
• be equipped with adequate fuses and electrical safety measures, in particular proper grounding.
See also technical data of all components regarding the different minimum system requirements!
NOTE
• Additional electrical safety measures such as residual current breakers may be necessary to
meet local laws and regulations!
• External power switches (e.g. emergency stop switches) must meet IEC 60947-1 and
IEC60947-3 requirements. Such devices must be clearly labeled and accessible at any time.
• External connections and extension lines must be provided with a grounded conductor lead
(3-pole couplings, cord or plug equipment). All electrical cables used must be suitable for the
required power rating.
5.3 Factors affecting chilling capacity
The available chilling capacity is dependent on various factors. The most important aspect to be
aware of is that the chilling capacity diminishes as the chilling temperature is lowered. In the case
of the F-105 it is approx. 600W at 20 °C and only around 50W at –5°C. The ambient temperature
has an effect as well. At room temperatures above 35 °C the chiller's air cooling may, depending on
chilling capacity, no longer be sufficient and the chiller may switch off for safety reasons to protect
itself against overheating. At an ambient temperature of 30°C the F-105 still has a chilling capacity
of around 150–W. We recommended a chilling temperature setting of 10–15 °C and a room tempe-
rature that does not exceed 25 °C. Outside of those parameters, the chilling capacity is substantially
reduced.
