Page 19: Operation
Recirculating coolers Operation 5.1. Preparations  Place the unit in an upright position.  The place of installation should be large enough and provide sufficient air ventilation to ensure the room does not warm up excessively because of the heat the instrument rejects to the environment.
Page 20: Return Flow Safety Device
Operation Notice: Cooling water circuit Risk of oil leaking from the cooling circuit (compressor) of the recirculating cooler into the cooling water in case of a fault in the circuit! Observe the laws and regulations of the water distribution company valid in the location where the unit is operated.
Page 21: Bath Fluids
Bath fluids Caution: No liability for use of other bath liquids! Please contact JULABO before using other than recommended bath fluids. JULABO takes no responsibility for damages caused by the selection of an unsuitable bath fluid Do not use alcohols. Water: The quality of water depends on local conditions.
Page 22: Power Connection
Operation 5.5. Power connection Caution:  Only connect the unit to a power socket with earthing contact (PE – protective earth)! We disclaim all liability for damage caused by incorrect line voltages!  The power supply plug serves as safe disconnecting device from the line and must be always easily accessible.
Page 23: Draining
Recirculating coolers 5.7. Draining Notice:  Do not drain the bath fluid while it is hot or cold! Check the temperature of the bath fluid prior to draining (by switching the unit on for a short moment, for example).  Store and dispose of the used bath fluid according to the environmental protection laws.
