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.

 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 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

 You received a product conceived for industrial use. 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.
