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 Chiller F-125 is a closed-circuit cooler for use with rotary evaporators. The
F-125 has a control unit and display built in to regulate and indicate the actual and set value of the
cooling temperature.
The Recirculating Chiller is designed for installation of a Rotavapor® R-151 / 152 / 153 / 220 / 220 SE on
top of the instrument.
The environmentally-friendly refrigerant R134 is used as the refrigerating medium.

This section describes how the instrument has to be installed. It also gives instructions for the initial
start-up.
NOTE
Inspect the instrument for damage during unpacking. If necessary, prepare a status report immediately and inform customer support 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 transport.
To move the instrument, loosen the clamps of the wheels, move the instrument and afterwards
secure the wheels by the clamps again.
5.1 Installation site
5 Putting into operation
Put the instrument onto a clean, stable and horizontal surface. Consider the maximum product dimensions and weight. Obtain the environmental conditions as described in section 3.1, technical data.
Installation prerequisites and installation steps:
Do not place any objects in front 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.•
NOTE
After transport, wait at least 1 hour before switching on the chiller! Within this time the refrigerant •
gathers in the compressor, avoiding damage to 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 may collect!
DANGER
Death or serious injuries when used in explosive environments.
Do not store or operate the instrument in explosive environments•
Remove all sources of flammable vapors•
Do not store chemicals in the vicinity of the device•
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•
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.
Utilize a second person to transport 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•
5.2 Cooling water routing
Independent of the number of coolers, the cooling water inlet has to be connected in ascending order
starting with the cooler closest to the receiving vessel. The cooling water outlet is always the upper
connector.

5.3 Electrical connections
!
The BUCHI Recirculating Chiller F-125 is aimed to be installed stationary and is not equipped with
a power plug. The electrical installation must be performed by an electrician or equivalent specialist.
After the installation procedure an electrical safety test must be performed to verify a safe system
condition such as sufficient grounding.
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.•
The Chiller and the Rotavapor•

should use different phases.
5 Putting into operation
WARNING
Death or serious burns by electric current at installation.
The instrument must be installed by an electrician or equivalent specialist•
After installation, the instrument must be tested for electrical safety•
Risk of instrument damage if mains supply is incorrect.
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 used power cords used must meet the input
power requirements.
If you have a pump connected to the system the pump can be plugged into the power from the •
Recirculating Chiller F-125.

mixture of ethylene glycol / water at least 30/60, which does not freeze until -16 °C.
NOTE
If you have a large closed cycle cooling system (e.g. long hoses, many condensers connected to the
system in series) fill the refrigerant tank to maximum level.
6 Operation
Risk of instrument damage if wrong cooling medium is used.
NOTICE
Check to ensure that the cooling medium is suitable for use at the desired cooling tempera-•
ture and does not freeze at the working temperature
6.3 Start operation
NOTE
See installation instructions (chapter 5.1) for initial startup!
WARNING

Before starting, the rollers of the instrument must be blocked•
Start the Recirculating Chiller by switching on the Instrument by the main switch. Press start on the
Chiller to fill the cooling coils.
6.4 No BUCHI vacuum controller connected to the system
Preparation steps
System must be in good working order. See final installation check, section 5.1.•
Turn on instrument.•
Check level of cooling transfer medium as described in section 6.1 Level indicator.•
Set the desired working temperature by the UP and DOWN buttons.•
Press the START button to start the cooling process.•
Check the actual temperature on the Chiller, start working when the required temperature is •
reached
20 F-125 Manual, Version B
Working steps
The cooling temperature can be adjusted during the operation process by pressing the UP and •
DOWN buttons on the Chiller.
If the Chiller can’t keep the required temperature perform a slower distillation, by means of •
decreasing the vacuum to a slightly higher level so that less vapor is coming to the cooling coil.
Steps for end of process
Press the STOP button on the Chiller.•
The cooling stops immediately. ➡
