4.3. Safety instructions Follow the safety instructions to avoid personal injury and property damage. Also, the valid safety instructions for workplaces must be followed. Only connect the unit to a power socket with an earthing contact (PE – protective earth)! The power supply plug serves as a safe disconnecting device from the line and must always be easily accessible. Place the unit on an even surface on a base made of nonflammable material.
Preparations 5. 5.1. Preparations Installation 5.2. Place the unit on an even surface on a pad made of non-flammable material. Press down the castor levers on model FT900. The instrument should be set up at a frost-proof and dry location. 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. (Max. permissible ambient temperature: 35 °C).

The power supply plug serves as safe disconnecting device from the line and must be always easily accessible.
6.2. Switching On The immersion cooler is turned on and off with the mains switch. (1). The control light in the switch will illuminate. The immersion probe – as part of the cooling circuit – should not be exposed to bath temperatures above the working temperature of the immersion cooler. This would cause damage to the compressor. Do not immerse a frosted immersion probe into hot bath oil. DANGER OF INJURY! 19514616-V2.doc 26.07.
7. 8. TROUBLESHOOTING Malfunction of compressor: The cooling compressor is equipped with an overload protection device that will be triggered by overheating or excessive current consumption. Possible causes include insufficient ventilation or contamination of the condenser. After a cool-down phase, the motor is automatically switched on again. Interruption of the cooling loop (FD200) by a bended tube.
Cleaning / repairing the unit FT900 The ventilation grid (7) is detached by unscrewing the four mouting screws (FT900). Clean the ribbed condensor with a vacuum cleaner. Replace the hood or the ventilation grid. Switch on the unit. Clean the outside of the unit using a wet cloth and low surface tension water.
