◦ Temperature must always be set to at least 25°C lower than the fir point of the media used.

◦ Beware of hazards due to:

• Flammable material or media with a low boiling temperature

• Overfilling of media

• Unsafe container

◦ Process pathogenic materials only in closed vessels.

◦ Check the instrument and accessories before hand for damage each time you use them. Do not use damaged components. Safe operation is only guaranteed with the accessories described in the "Accessories" chapter. Accessories must be securely attached to the device and cannot come off by themselves. Always disconnect the plug before fitting accessories.

◦ Ensure that the external temperature sensor is inserted in the media to a depth of at least 20mm.

◦ When using metal vessels, do not place the temperature sensors on the bottom of the vessel. Placing sensors on the vessel bottom can cause excessively high temperature to be measured especially in media which have poor conductivity. The tip of the measuring sensor must be at least 5mm from the vessel bottom, a distance of 10mm is ideal.

◦ The instrument can only be disconnected from the main power supply by pulling out the mains plug or the connector plug.

◦ The voltage stated on the label must correspond to the main power supply.
