Operating manual

1. Intended use

JULABO circulators have been designed to control the temperature of specific fluids in a bath tank.

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

 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.

PID1

 The PID temperature control adapts the heat supplied to the thermal

requirements of the bath.

 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.

2. Operator responsibility – Safet y 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.

Persons: The operator is responsible for the qualification of the personnel operating the units. The operator should be constantly informed about the dangers involved with their job activities as well as preventive actions. Make sure all persons expected to carry out operation, installation and maintenance of the unit read and understand the safety information and operating instructions.

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

display) or contamination.

 Make sure the product is regularly checked for proper condition.  Regularly check (at least every 2 years) the proper condition of the mandatory, warning,

prohibition and safety labels.

 Take care that the mains supply features a low impedance to avoid any negative affects on

the instrument being operated in 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 influence other units with components susceptible to magnetic fields (e.g. a monitor). We recommend to keep a minimum distance of 1 m.

 Permissible ambient temperature: max. 40 °C, min. 5 °C.  Permissible relative air humidity: 50 % (40 °C).  Do not store in an aggressive atmosphere. Protect from contaminations.  Do not expose to sunlight.
