Intended use

1. Intended use
JULABO recirculating coolers have been designed for temperature application to specific
fluids. The pump connections can be used for cooling applications in an external circuit at a
constant temperature.
JULABO water baths 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 AWC 100 recirculating cooler is suitable for the cooling of water in loop circuits. A
pump supplies the cooling water to the external circuit via the cooling water outlet. The
recirculating cooler constantly withdraws heat from the circulating fluid. The water
temperature varies with the ambient temperature and may not exceed 40 °C.
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.
¾The personnel operating the units should be regularly instructed about the dangers
involved with their job activities as well as measures to avert these dangers.
¾Make sure all persons tasked with operating, installing, and maintaining the unit have
read and understand the safety information and operating instructions.
¾When using hazardous materials or materials that could become hazardous, the unit
may be operated only by persons who are absolutely familiar with these materials and
the unit. These persons must be fully aware of possible risks.

Safety recommendations for the operator
¾You received a product conceived for industrial use. Nevertheless, avoid strikes to the
housing, vibrations, damages to the keypad foil (keys, display) or contamination.
¾Make 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.
¾Take care that the mains supply features a low impedance to avoid any negative affects
on the instrument being operated in the same mains.
¾This 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.
¾Permissible ambient temperature: max. 40 °C, min. 5 °C.
¾Permissible relative air humidity: 50 % (40 °C).
¾Do not store in an aggressive atmosphere. Protect from contaminations.
¾Do not expose to sunlight.
Appropriate Operation
Only qualified personnel is authorized to perform configuration, installation, maintenance
and repairs of the water bath.
Routine operation can also be carried out by untrained personnel who should however be
instructed by trained personnel.
Use
For the use according to the intended purpose, special material requirements have to be
respected (bath fluids). Only use non-acid and non corroding materials.
Observe all warnings for the used materials (bath fluids) and the respective instructions
(safety data sheets).
Only use the unit in well ventilated areas.
The recirculating coolers are not for use in explosive environment.
Operator responsibility – Safety instructions

When using hazardous materials or materials that could become hazardous, the operator
must affix the enclosed safety labels to the front of the unit so they are highly visible:
If this unit is intended for use within the United States of America, all 3 warning labels must
be affixed to the housing of the unit prior to use. Directions for the positioning of the
individual warning labels are enclosed with the warning labels included in the delivery.
Warning labels must be easily visible to users.
