2 Warning and Safety Instructions
The laboratory hotplate may only be generally opened by authorized persons for safety and functional
reasons, work on electrical equipment may therefore only be performed by trained professionals. Unau-
thorized interference with laboratory hotplates, and negligent or intentional damages will void the warranty.
The laboratory hotplate falls under protection class I. It is designed according to DIN VDE 0411, part 1
(EN 61 010, part 1) and DIN VDE 0411, Part 2-010 (EN 61 010, Part 2-010), protective measures for elec-
tric heaters, built and tested. It has left the factory in perfect condition. In order to maintain this condition
and ensure a safe operation, the user must follow the instructions and warnings contained in this manual.
Before switching on the unit, make sure that the voltage on the nameplate of the laboratory hotplate corre-
spond with the specified voltage and mains voltage.
In order to completely disconnect the laboratory hotplate from the power supply, always pull the power
plug. The energy regulator does not act as a network disconnection point.
It is important to ensure that the powercable does not come in contact with the hot plate or other hot ob-
jects. With defective power cable, the device must be disconnected from the mains immediately and be
send in for repair.
The laboratory hotplate must not be surrounded by combustible materials; a minimum distance from any
combustible objects of 0.5 m must be maintained. A minimum distance of 0.3 meters to all other objects
must be maintained.
The decor marks the centre of the heating surface. The surface is hot even outside of the decoration.
Do not let hard objects drop onto the glass ceramic surface. Punctiform shock loads can result in break-
ages of the glass ceramic surface.
In case of cracks, fractures or fractures of the ceramic surface and when it is assumed that a safe opera-
tion is not possible, shut down the laboratory hotplate (remove the power cable) and secure to prevent ac-
cidental startups.
The heating surface temperature can reach max. 555 °C. Therefore:
CAUTION: Deflagration, explosion and fire hazard when heating combustible liquids
of a flashpoint below 580 °C! Only heat liquids of a flashpoint above 580 °C!
Observe increased flammability of heated fluids!
Prevent contact of heated fluids with the heating surface (e.g., from spills, leaking gas or when
boiling over) by covering the vessel!
The laboratory hotplate by SI Analytics must be installed and connected so that maximum
safety is guaranteed for personnel and material.
!
The surface of the heating and cooking appliances will be hot during the operation, therefore use cau-
tion when working with the laboratory hotplate.
!
The use of aluminium foil or plastic containers on the hot cooking zones is not permitted! These sub-
stances melt, and bond and can cause cracks or fractures in the glass ceramic surface when cooling.
Prevent repeated burning of contaminants and overcooking. Lime scale deposits damage the ceramic sur-
face.
Should the heating surfaces cannot be switched off due to a defect of the energy regulator, immediately
disconnect the laboratory hotplate by pulling the plug from the power supply.
