The appropriate power cable should be connected BEFORE connection to the power supply.

Safety Advice

❖HIGH TEMPERATURES ARE DANGEROUS as they can cause serious burns to operators and

ignite combustible material. Users should be aware of the following safety advice:

❖USE CARE AND WEAR PROTECTIVE GLOVES TO PROTECT HANDS.

❖DO NOT use combustible substances near hot objects.

❖NEVER lift or carry the instrument until it has been switched off and allowed to cool for at least 30

minutes. The hot warning light will give guidance.

❖The unit should be carried using both hands with the fingers under the side edges.

❖NEVER move or carry the unit with containers on the top plate or while still connected to the power

supply.

❖There is a danger of liquid spillage if containers are over-filled and stirred at high speed. Always

build stirrer speed slowly and never stir more rapidly than necessary.

❖NEVER place a cold glass vessel onto a hot plate which is already hot.

❖NEVER use a retort rod longer than 600 mm (23.6 in.).

❖When a retort rod is installed with apparatus attached, or when swivelling support rods, take care

that there is sufficient weight on the plate to prevent the whole unit tipping over.

❖When using a retort stand, in order to provide the unit with adequate ventilation the base of the

retort stand must NOT exceed 19.5 mm (0.75 in.) in height and 125 mm (5 in.) in width.
