Operating manual

1.Intended use

JULABO circulators have been designed to control the temperature of 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, semiluxury foods and tobacco, or pharmaceutical and medical products.

Direct temperature control means unprotected contact of the object with the bath medium (bath fluid).

1.1.Description

ICC

TCF

ATC3

RS232

RS485

Pt100

SMART

PUMP

 The circulators are operated via the splash-proof keypad. The implemented microprocessor technology allows to set and to store different values that can be indicated on the VFD COMFORT-DISPLAY and LCD DIALOG-DISPLAY. Three menu keys facilitate adjusting setpoints, warning and safety functions and menu functions.

 The integrated programmer allows storing and running temperature and timedependent processes.

 The control electronics including “ICC - Intelligent Cascade Control“ automatically adapts the heat supplied to the thermal requirements of the bath.

 The TCF - Temperature Control Features allow the user to have access to all important temperature control parameters. This means: Full control on the control mode and the chance to manually adjust or adapt control to the specific application.

 Absolute Temperature Calibration (ATC3) provides high temperature stability in the bath. With the 3-point calibration an offset is adjusted at three temperatures to ensure an accurate temperature pattern at the selected spot in the bath over the full temperature range.

 Electrical connections:

The serial interface, switchable from RS232 to RS485, allows modern process technology without additional interface.

Connection for Pt100 external sensor for external temperature measurement and control.

Alarm output for external alarm message or control of JULABO refrigerating baths or solenoid valve (cooling water).

The electronic module (option) provides 3 further analog connections (alarm input, standby input, recorder output, programmer input).

 The excess temperature protection conforming to IEC 61010-2-010 is a safety installation independent from the control circuit. This protection can be indicated and set on the LCD DIALOG-DISPLAY.

 The early warning system for low level signals that bath fluid needs to be refilled before the low level protection conforming to IEC 61010-2-010 causes a complete shut-down of the main functional elements.

 Intelligent pump system: The pump capacity (electronically adjustable via the motor speed) enables to adapt to varying conditions for internal and external temperature applications.

5.Preparations

5.1.Installation

G½"

HL, SL

•Place the unit on an even surface on a pad made of non-flammable material. Using the castors move the unit to the intended location. For better stability, apply the holding breaks on the front casters.

•Cooling machine, pump motor and electronics produce intrinsic heat that is dissipated via the venting openings! Never cover these openings!

•Keep at least 20 cm of open space on the front and rear venting grids.

•The place of installation should be large enough and provide sufficient air ventilation to ensure the room does not warm up excessively because of the heat the instrument rejects to the environment. (Max. permissible ambient temperature: 40 °C).

For a fault (leakage) in the refrigeration system, the standard EN 378 prescribes a certain room space to be available for each kg of refrigerant.

The refrigerant quantity is specified on the type plate.

>For 0.52 kg of refrigerant R-404A, 1 m3 of space is required.

>For 0.68 kg of refrigerant R-23, 1 m3 of space is required.

>For 0.2 kg of refrigerant R-508b, 1 m3 of space is required.

•Do not set up the unit in the immediate vicinity of heat sources and do not expose to sun light

•Before operating the unit after transport, wait about one hour after setting it up. This will allow any oil that has accumulated laterally during transport to flow back down thus ensuring maximum cooling performance of the compressor.

Only for water-cooled models:

Ensure circulation of cooling water by connecting the tubing to the cooling water inlet and outlet at the rear of the refrigerated circulator.

Cooling water connections: G½"

Important: For cooling water, see page 13

5.2.Bath fluids

Caution:

Carefully read the 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 calcification in the bath.

•Ferrous water can cause corrosion - even on stainless steel.

•Chloric water can cause pitting corrosion.

•Distilled and deionized water is unsuitable. Their special properties cause corrosion in the bath, even in stainless steel.

The circulator is used for temperature application to external, closed systems (loop circuit) with simultaneous temperature application in the circulator bath.

•Unscrew the M16x1 collar nuts on the pump connectors with a 19 mm (3/4“) wrench and remove the sealing disks. Using the collar nuts, screw on the tubing connection fittings (for tubing 8 mm or 12 mm in diameter) delivered with the unit and tighten firmly. (Pressure pump: 22, suction pump: 21)

•Push on the tubing, and secure with tube clamps.

•Attach the tubing to the connectors of the external closed system, e.g., an instrument with a pressure-resistant temperature jacket or a temperature coil, and fasten with tube clamps to prevent slipping.

Temperature application to external, open systems

The circulator is equipped with both a pressure and suction pump

for external temperature application in open systems.

Differing flow rates of the pressure and suction pumps should be compensated. To maintain a constant liquid level, the JULABO „D+S“ Level Adapter is recommended for the external bath tank. The flow rate of the pressure pump will be then regulated by a built-in float device. The liquid level may be changed by a height adjustment on the „D+S“ Level Adapter.

Accessory: „D+S“ Level Adapter	Order No. 8 970 410
Important:

	The liquid level should be equal in the internal and external
	baths (absolute height).

Warning: Tubing:

At high working temperatures the tubing used for temperature application and cooling water supply represents a danger source.

A damaged tubing line may cause hot bath fluid to be pumped out within a short time. This may result in:

•Burning of skin

•Difficulties in breathing due to hot atmosphere

24

HL, SL

Safety recommendations

•Employ suitable connecting tubing.

•Make sure that the tubing is securely attached.

•Avoid sharp bends in the tubing, and maintain a sufficient distance from surrounding walls.

•Regularly check the tubing for material defects (e.g. for cracks).

•Preventive maintenance: Replace the tubing from time to time.

5.4.Filling / draining

Notice:

•Pay attention to the thermal expansion of bath oil during heating to avoid overflowing of the liquid.

•Do not drain the bath fluid while it is hot! Recommendation: Temperature range 5 °C to 40 °C

Check the temperature of the bath fluid prior to draining (by switching the unit on for a short moment, for example).

•Store and dispose the used bath fluid according to the laws for environmental protection.

Filling

Take care that no liquid enters the interior of the circulator.

•Recommended maximum filling level with water as bath fluid: 30 mm below the tank rim

•Recommended maximum filling level with bath oils: 40 mm below the tank rim

After filling, immerse the samples in the bath or place the lid on the bath, in case the opening is not to be used.

The circulator provides an early warning system for low level (description – please refer to page 32) that may be triggered when changing samples in the bath.

Draining:

•Turn off the unit and disconnect the mains cable from the power source.

•Hold the venting grid, pull out and remove.

•Slide a short piece of tube onto the drain connection and hold it into a container.

•Loosen the drain screw a few turns and drain the unit completely.
