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

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.

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 – 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.

4 www. .com information@itm.com1.800.561.8187

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.

Handling:

Nevertheless, avoid strikes to the housing, vibrations, damages to the keypad foil (keys,

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.

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 may not be filled with flammable materials. Fire hazard!

Only use recommended materials (bath fluids). Only use recommended materials (bath fluids).

Only use non-acid and non corroding materials.

Information about the used refrigerants

The Regulation (EU) No. 517/2014 on fluorinated greenhouse gases applies to all systems

which contain fluorinated refrigerants and replaces (EC) 842/2006.

The aim of the Regulation is to protect the environment by reducing emissions of fluorinated

greenhouse gases.

Among other things it regulates the emission limits, use and recovery of these substances. It

also contains requirements for operators of systems which require / contain these substances

to function.

Under Regulation 517/2014, the operator of a system of this nature has the following duties:

•The operator must ensure that the equipment is checked at regular intervals for leaks.

•These intervals depend on the CO2equivalent of the system. This is calculated from the

refrigerant fill volume and type of refrigerant. The CO2equivalent of your system is

shown on the model plate.

•The operator undertakes to have maintenance, repair, service, recovery and recycling

work carried out by certified personnel who have been authorized by JULABO.

•All such work must be documented. The operator must keep records and archive them

for at least five years. The records must be submitted to the relevant authority on

request.

Refer to the text of the Regulation for further information.

inside an equilateral triangle. “Warning of a dangerous situation (Attention!

Please follow the documentation).”

The danger is classified using a signal word.

Read and follow these important instructions for averting dangers.

Warning:

Describes a possibly highly dangerous situation. If these instructions are not

followed, serious injury and danger to life could result.

Caution:

Describes a possibly

dangerous situation. If this is not avoided, slight or minor

injuries could result. A warning of possible property damage may also be

contained in the text.

Notice:

Describes a possibly harmful situation. If this is not avoided, the product or

anything in its surroundings can be damaged.

3.2. Explanation of other notes

Note!

Draws attention to something special.

Important!

Indicates usage tips and other useful information.

3.3. Safety recommendations

Follow the safety recommendations to prevent damage to persons or property.

Further, the valid safety instructions for working places must be followed.

•Only connect the unit to a power socket with earthing contact (PE –

protective earth)!

•The power supply plug serves as safe disconnecting device from the line

and must be always easily accessible.

•Operation is permitted with non-flammable liquids only.

•Place the instrument on an even surface on a pad made of non-

inflammable material.

16 www. .com information@itm.com1.800.561.8187

•Do not stay in the area below the unit.

•Make sure you read and understand all instructions and safety precautions

listed in this manual before installing or operating your unit.

•Never operate the unit without bath fluid in the bath.

•Check the filling level of the bath fluid from time to time. Pump and heater

must always be fully covered with the bath fluid!

•The instrument is not suited for unsupervised continuous operation.

•Do not drain the bath fluid while it is hot!

Check the temperature of the bath fluid prior to draining (by switching the

unit on for a short moment for example).

•Observe the limited working temperature range when using plastic bath

tanks.

•Employ suitable connecting tubing.

Make sure that the tubes are securely attached.

•Never operate damaged or leaking equipment.

•Always turn off the unit and disconnect the mains cable from the power

source before performing any service or maintenance procedures, or

before moving the unit.

•Always empty the bath before moving the unit.

•Never operate equipment with damaged mains power cables.

•Some parts of the bath cover and the pump connections may become

extremely warm during continuous operation. Therefore, exercise particular

caution when touching these parts.

Notice: Check the safety installations at least twice a year!

•Excess temperature protection according to IEC 61010-2-010.

With a screwdriver turn back the adjustable excess temperature protection

until the shut-down point (actual temperature).

•Low level protection according to IEC 61010-2-010.

To check the function of the float, it can be manually lowered with a

screwdriver for example.
