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, semi-luxury 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

PID1

	40	80
		120
	0	160

°C

The circulators are operated via the splash-proof keypad. The implemented microprocessor technology allows to set and to store the setpoint that can be indicated on the LED temperature display.

The PID temperature control adapts the heat supplied to the thermal requirements of the bath.

ATC - Absolute Temperature Calibration (1-point calibration)

Safety installations conforming to IEC 61010-2-010

The excess temperature protection is a safety installation independent from the control circuit.

The safety value is set using a tool (screwdriver).

If the low level protection device is triggered, a complete shutdown of the heater and circulating pump is effected.

Electrical connection:

Alarm output for external alarm message or control of JULABO refrigerating baths.

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 circulator. These persons must be fully aware of possible risks.

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 temperature: max. 40 °C, min. 5 °C.

Permissible relative humidity: 50% (40 °C).

Do not store the unit in an aggressive 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 operation can also be carried out by untrained personnel who should however be instructed by trained personnel.

Use:

The bath can be filled 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 formation of explosive mixtures. Only use the unit in well ventilated areas. The unit is not for use in explosive atmosphere.

Only use recommended materials (bath fluids). Only use non-acid and non corroding materials.

Operator responsibility – Safety recommendations

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. Attention! Observe instructions.
	(operating manual, safety data sheet)
2	Mandatory label M018:	Colors: blue, white
	Carefully read the user information prior to beginning operation.
or	Scope: EU
2	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.

2.1.Disposal

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.

This unit contains the refrigerants R134a – at this time considered not to have any negative 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.

Valid in EU countries

See the current official journal of the European Union – WEEE directive.

Directive of the European Parliament and of the Council on waste electrical and electronic equipment (WEEE).

This directive requires electrical and electronic equipment marked with a crossed-out trash can to be disposed of separately in an environmentally friendly manner.

Contact an authorized waste management company in your country.

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