Cryo-Compact Circulators Operating manual 1. Intended use JULABO Cryo-Compact Circulators have been designed for temperature application to specific fluids in a bath tank. The units feature pump connections for temperature control of external systems (loop circuit). JULABO circulators are not suitable for direct temperature control of foods, semi-luxury foods and tobacco, or pharmaceutical and medical products.
Operator responsibility – Safety instructions 2. Operator responsibility – Safety instructions The products of JULABO ensure safe operation when installed, operated, and maintained according to common safety regulations. This section explains the potential dangers that may arise when operating the circulator and also specifies the most important safety precautions to preclude these dangers as far as possible. The operator is responsible for the qualification of the personnel operating the units.
Cryo-Compact Circulators sheets). Insufficient ventilation may result in the formation of explosive mixtures. Only use the unit in well ventilated areas. Only use recommended materials (bath fluids). Only use non-acid and non corroding materials. When using hazardous materials or materials that could become hazardous, the operator must affix the enclosed safety labels (1 + 2) to the front of the unit so they are highly visible: 1 Warning label W00: Colors: yellow, black Danger area.
Operator responsibility – Safety instructions 2.2. EC Conformity The products described in the operating instructions conform to the requirements of the following European guidelines: Directive of the European Parliament and of the Council on the approximation of the laws of the Member States relating to machinery.

Safety notes for the user 3. 3.1. Safety notes for the user Explanation of safety notes In addition to the safety warnings listed above, warnings are posted throughout the manual. These warnings are designated by an exclamation mark inside an equilateral triangle. “Warning of a dangerous situation (Attention! Please follow the documentation).” The danger is classified using a signal word. Read and follow these important instructions. Warning: Describes a possibly highly dangerous situation.
Cryo-Compact Circulators overflowing of the fluid. Prevent water from entering the hot bath oil. Do not drain the bath fluid while it is hot! Check the temperature of the bath fluid prior to draining (e.g., by switching the unit on for a short moment). Use suitable connecting tubing. Avoid sharp bends in the tubing, and maintain a sufficient distance from surrounding walls. Make sure that the tubing is securely attached. Regularly check the tubing for material defects (e.
Safety notes for the user The following questions should help to recognize possible dangers and to reduce the risks to a minimum. Are all tubes and electrical cables connected and layed? Note: sharp edges, hot surfaces in operation, moving machine parts, etc.

Cryo-Compact Circulators 5. 5.1. Preparations Installation Place the unit on an even surface on a base made of nonflammable material. Cooling machine, pump motor and electronics produce intrinsic heat that is dissipated via the venting openings.! Never cover these openings! Be sure that the flow of ventilation can exit under the instrument.
Preparations Return flow safety device For this reason, shut-off valves can be integrated in the loop circuit. Order No. 8 970 456 8 970 457 Description Shut-off valve (suitable up to +90 °C) Shut-off valve (suitable up to +200 °C) Temperature application to external, closed systems SERIAL ALARM STAND-BY REG+ E-PROG ext Pt100 Unscrew the M16x1 collar nuts on the pump connectors with a 19 mm (3/4“) wrench and remove the sealing disks.
Cryo-Compact Circulators 5.3. Tubing Warning: Tubing: At high working temperatures, the tubing used for temperature control and for the cooling water supply represents a danger source. A damaged tubing line may allow a large amount of hot bath fluid to be pumped out within a short time. This may result in: Burning of skin Breathing difficulties due to hot atmosphere Safety instructions Use suitable connecting tubing. Make sure that the tubing is securely attached.
Preparations 5.4. Bath fluids Caution: Carefully read the material safety data sheet of the bath fluid used, particularly with regard to the fire point! If a bath fluid with a fire point of 65 °C is used, only supervised operation is possible. Water: The quality of water depends on local conditions. Due to the high concentration of lime, hard water is not suitable for temperature control because it leads to scale in the bath Ferrous water can cause corrosion, even on stainless steel.
Cryo-Compact Circulators 6. 6.1. Operating procedures Power connection Caution: Only connect the unit to a power socket with an earthing contact (PE – protective earth)! The power supply plug serves as a safe disconnecting device from the line and must always be easily accessible. Never operate the unit with a damaged mains power cable. Regularly check the mains power cables for damage.
Operating procedures Important: When using a bath fluid, the change in volume in case of change in temperature has to be respected. Fill in a little amount of bath fluid only so that the low level alarm is not triggered. Low level alarm is triggered at the following liquid level: CF31 75 to 80 mm below the tank rim CF41 80 to 85 mm below the tank rim When reaching the working temperature, check the liquid level. If the cooling coil is not completely covered with bath fluid, refill it. 6.3.

Important: Connect the external voltage or current source or a programmer to the circulator via the socket REG+E-PROG (see page 51).
Menu functions OFF-Mode Normally the circulating pump is switched via the start/stop signal. However, if circulation should be maintained also for the -OFF- condition, the parameter >pump on< needs to be set. Possible parameters: pump off (factory setting) pump on Language There are two options for the language of the LCD DIALOG-DISPLAY: German or English. Possible parameters: deutsch / englisch German / English Reset Use this to reset all values to factory setting (except date and time).
Cryo-Compact Circulators Warning: The working temperature range of the Cryo-Compact Circulator is determined during configuration. If set to >Control<, this range cannot be exceeded. If set to > serial < and > eprog <, heat or cold is applied to the bath without control. The permissible maximum temperature can be exceeded. The user has to take adequate precautions for temperature control.
Menu functions 8.2. Control The Cryo-Compact Circulator is conceived for internal and external temperature control. Switching is carried out in this submenu.

Main menu >Limits Interface serial ATCalibration ESC ESC Limits >SetMax :300.00°C SetMin :-94.99°C HeatingMax: 100% CoolingMax: 0% IntMax :300.00°C IntMin :-94.
Cryo-Compact Circulators IntMax: and IntMin: Limit setting Setting range: see working temperature range page 9 The limits IntMax and IntMin are only valid for external control. IntMax and IntMin are used to limit the expected internal bath temperatures to any upper and lower values. The temperature controller cannot exceed these limits even if it would be required for reaching the temperature in the external system. Consequently the external setpoint may thus not be reached.
Menu functions 8.7. Serial interface For communication between Cryo-Compact Circulator and a PC or a superordinated process system the interface parameters of bath units must be identical. The adjustment is usually carried out one time only in the menu >Interface serial<.
