Operator responsibility – Safety recommendation s

2. Operator responsibility – Safety recommendations

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.  The personnel operating the units should be regularly instructed about the dangers involved with

their job activities as well as measures to avert these dangers.

 Make sure all persons tasked with operating, installing, and maintaining the unit have read and

understand the safety information and operating instructions.

 When using hazardous materials or materials that could become hazardous, the circulator may be

operated only by persons who are absolutely familiar with these materials and the cir c ulator. These persons must be fully aware of possible risks.

If you have any questions concerning the operation of your unit or the information in this manual, please contact us!

Contact

Safety instructions for the operator:

 You have received a product designed for industrial use. Nevertheless, avoid strikes to the

housing, vibrations, damage to the operating-element panel (keypad, display), and contamination.

 Make sure the product is checked for proper condition regularly (depending on the conditions of

use). Regularly check (at least every 2 years) the proper condition of the mandatory, warning, prohibition and safety labels.

 Make sure that the mains power supply has low impedance to avoid any negative effects on

instruments being operated on the same mains.

 This unit is designed for operation in a controlled electromagnetic environment. This means that

transmitting devices (e.g., cellular phones) should not be used in the immediate vicinity. Magnetic radiation may affect other devices with components sensitive to magnetic fields (e.g., monitors). We recommend maintaining a minimum distance of 1 m.

 Permissible ambient tem perature: ma x . 40 °C, min. 5 °C.  Permissible relative humidity: 50% (40 °C).  Do not store the uni t in an aggressi ve atmos ph er e .  Protect the unit from contamination.  Do not expose the unit to sunlight.

waste is not permitted!

Use:

The bath can be fil led with flammable materials. Fire hazard! There might be chemical dangers depending on the bath medium used. Observe all warnings for the used materials (bath fluids) and the respective instructions (safety data sheets). Insufficient ventilation may result in the format ion of explo si ve mi xtures. Only use the unit in well ventil ate d ar eas.

Only use recommended materials (bath fluids). O nly use non-acid and non corroding materials. When using hazardous materials or materials that could become hazardous, the opera to r must affix

the enclosed safety labels (1 + 2) to the front of the unit so they are highly visible:

or 2

Particular care and attention is necessary because of the wide operating range. There are thermal dangers: Burn, scald, hot steam, hot parts and surfaces that can be touched.

Observe the instructions in the manuals for instruments of a different make that you connect to the circulator, particularly the respective safety recommendations. Also observe the pin assignment of plugs and technical specifications of the p r oducts .

2.1. Disposal

The circul ator cont ains a back -up battery that supplies voltage to memory chips when the unit is switched off. Do not dispose of the battery with household waste! Depending on battery regulations in your country, you might be obliged to give back used or defect batteries to gathering places. The product may be used with oil as bath fluid. These oils fully or partially consist of mineral oil or synthetic oil. For disposal, observe the instructions in the safety data sheets.

See the current official journal of the European Union – WEEE directive. Directi v e o f the E ur op ea n Par l i am e nt and of the Cou nc i l on waste elec tr i cal and electro ni c eq ui pm e nt (WEEE).

Carefully read the safety data sheet of the bath fluid used, particularly with regard to the fire poi nt! If a bath fluid with a fire point of ≤6 5 °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

• Attach the tubings 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 flo w 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 adjustm e nt on t h e „D+ S“ Level Adapter.

Filling

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

• Recommended maximum filling level with water as bath fluid: 30 mm bel ow t he ta nk 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

Draining

• Turn the unit off with the mains switch.

• Place the he ati n g cir c ulator near the rim of the table. Use a
