Warning and safety instructions

For reasons of safety technology and functional integrity the Laboratory hot plates must only be opened by
authorised staff; work on the electrical system, e.g., must only be performed by trained specialists. In the
case of unauthorised intervention in the Laboratory hot plates and negligent or deliberate damage the war-
ranty will lapse.
The Laboratory hot plates correspond to Protection Class 1. They were manufactured and tested accord-
ing to DIN VDE 0700 Part 1/04.88 (HD 251 S3 and Supplement 1-3) and DIN VDE 0700 Part 6/11.89
(HD 275 S1, Supplement 1) in combination with the draft DIN VDE 0700 Part 6A8/04.89, Protective
measures electric heating apparatus. They have left the plant in a perfect safety-technological condition.
To preserve this condition and ensure safe operation, the user has to observe the information and warning
notes contained in the present operating instructions.
Prior to switching on it has to be ensured that the voltage indicated on the specification plate of the Labo-
ratory hot plates matches the mains voltage. The mains plug must only be plugged to a socket with pro-
tective earthing. The protective effect must not be neutralised by an extension line without protective
earthing. Any interruption of the protective conductor within or outside the laboratory hot plates, or any
loosening of the connector of the protective earthing may lead to the laboratory hot plates becoming haz-
ardous. Any wilful interruption is not admitted.
Please make sure that the connecting lines do not come in contact with the hot heating zone or other hot
objects. The Laboratory hot plates are to be kept away from inflammable substances, from which a min.
distance of 0.5 m is to be observed.
The decoration marks the centre of the heating zone. However, the surface will also be heated up outside
the decorated surface.
Please avoid hard objects falling on the glass-ceramics surface. Punctual impact may lead to the breaking
of the glass-ceramics material.
If fissures, cracks, or breaks occur on the glass-ceramics surface, or if it has to be assumed that safe op-
eration is no longer possible, the Laboratory hot plates have to be put out of operation (remove mains ca-
ble) and secured against inadvertent putting to operation.
CAUTION: Risk of deflagration, explosion and fire hazard when heating flammable liquids!
!
Always heat up liquids with a flash point above 580 °C!
Be aware of increased ease of ignition of hot liquids!
Always cover vessel to prevent hot liquids from getting into contact with the heating zone (e.g.
by liquid splashing or boiling over, or through escaping gases)!
The Laboratory hot plates must be set up and connected in a way that ensures maximum
safety for people and material handled.
If the Laboratory hot plates are used outside the laboratory, e.g. in the office, workshop, or household, the
hazards which are typical for such rooms may emanate from the devices. The Laboratory hot plates must
not be used to heat rooms (improper use!).
! The surface of heating and boiling devices becomes hot during operation, so please be careful:
children, especially small children should always be kept out of reach of such devices.
! Food to be prepared using fat or oil (e.g. chips) should only be prepared under supervision! Preparing
food in aluminium foils or plastic ware on the hot heating zones is not admissible! Such substances, and
especially sugar in solid or liquid form (food containing sugar) will melt, get stuck, and may cause cracks
or breaks in the glass-ceramics material when cooling down.
Repeated burning of soiling and boiling over is to be avoided. Calcereous deposits will harm the glass-
ceramics material.
