Operator responsibility – Safety recommenda tions

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 act iv ities 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 circulator. 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!

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 operate d 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.

 Permiss i ble am bient temperatur e: ma x . 40 °C, min. 5 °C.  Permissible relative humidity: 50% (40 °C).  Do not store the uni t in an aggressi ve atmosphere.  Protect the unit from contamination.  Do not expose the unit to sunlight.

Appropriate operation

Only qualified personnel is authorized to perform configuration, installation, maintenance and repairs of the circulator. Routine op er at ion can als o be c ar r i ed out by untrained per s o nnel who should however be i nstr ucted by trained per sonnel.

Use:

The bath can be filled with flammable materials. Fire hazard! There might be chemical dangers depending on the bath medium used. Observe al l war nings for the used materials (bath fluids) and the respective instructions (safety data sheets). Insufficient ventilation may result in the formation of explosive mixtures. Only use the unit in well ventil ate d ar eas.

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:

Warning label W00: Colors: yellow, black Danger area. Attention! Observe instructions. (operating manual, safety data sheet)

or 2

Mandatory label M018: Colors: bl ue , whi te Carefully read the user information prior to beginning operation. Scope: EU

Semi S1-0701 Table A1-2 #9 Carefully read the user information prior to beginning operation. Scope: USA, NAFTA

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.

Warning label W26: Colors: yellow, black Hot surface warning.

(The label is put on by JULABO)

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 products.

Operator responsibility – Safety recommenda tions

Valid in EU countries

Disposal with household waste (unsorted waste) or similar collections of municipal waste is not permitted!

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.

These units contains refrigerants– at this time considered not to have any nega tive effects on the ozone layer. However, during the long operating period of the unit, disposal prescriptions may change. So only qualified personnel should take care of disposal.

See the current official journal of the Europe a n U nion – WEEE di r ec ti ve. Directive of the Europ ean Parliam e nt an d o f th e Council on was te el ectrical and electro ni c eq ui pm e nt (WEEE). This direc ti v e r eq ui r es el ec tr i cal a nd electronic equipment marked with a crossedout trash can to be disposed of separately in an environmentally friendly manner. Contact an authorized waste management company in your country.

2.2. Warranty conditions

JULABO GmbH warrants its products against defects in material or in workmanship, when used under appropriate conditions and in accordance with appropriate operating instructions

Extension of the warr a nty per i o d – fre e of charge

With the ‘1PLUS warranty’ the user receives a free of charge extension to the warranty of up to 24 months, limited to a maximum of 10 000 worki n g h our s .

Preparations

Caution:

control because it leads to calcification in the bath.

5. Preparations

5.1. Installation

• Place the unit on an eve n surface on a pad ma de of nonflammable material.

F34: The circulator fitted with a stainless steel bridge is placed on on the back of the bath tank leaving the bath open on the front side.

• The pl ace of install ation should be large enough and pr ovi de sufficient air ventilation to ensure the room does not warm up excessively because of the heat the instrument radiates to the environment. (Max. permissible ambient temperature: 40 °C). With regard to a disturbance in the cooling loop (leakage), the guideli n e EN 37 8 pr esc r i b es a cer t ai n room space to be avai l able for each kg of refrigerant. The necessary amou nt o f refrigerant is sp ecified o n the ty p e pl at e. > For 0.25 kg of refrigerant R134a, a room space of 1 m required. > For 0.52 kg of refrigerant R404A, a room space of 1 m required. > For 0.49 kg of refrigerant R507, a room space of 1 m

is required.

• Set s elector dial for c ooli n g machine in position "1" for operation

5.2. Bath fluids

with HE circulator.

(only F25, F34)

• Keep at least 20 cm of open space on the fr ont and rear vent ing grid.

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

• Be for e operati ng th e uni t a ft er tra nsport, wai t ab ou t one ho ur after setting it up. This will allow any oil that has accumulated laterally during tra nsport to flow bac k dow n t h us ensuring m axi m um cool i ng performance of the compressor.

Only water cooled models:

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

• Cooling water connecter G¾"

• Cooling water see page 18

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 us e d, 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
