Operating manual
Operating manual
1. Intended use
JULABO Cryo-Compact Circulators have been designed for temperature application to
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
The Cryo-Compact 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.
RS232
The serial interface RS232 allows modern process technology without
additional interface.
2. Operator responsibility – Safety instructions
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:
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 the 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 configure, install, maintain, or repair the circulator.
Persons who operate the circulator must be trained in the particular tasks by qualified
personnel. The summarized user guidance (short manual) and the specification table with
information on individual parameters are sufficient for this.
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.
Only use recommended materials (bath fluids). Only use non-acid and non corroding
materials.

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

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)
Warning label W017: Colors: yellow, black
Low temperature 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 corresponding safety instructions. 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, follow the instructions in the material safety data sheets.
This unit contains the refrigerants R-404A, and R-134a, which at this time are not considered
harmful to the ozone layer. However, over the long operating period of the unit, disposal rules
may change. Therefore, only qualified personnel should handle the disposal.
