1.2 Product safety and dangers
The appliances described in this manual are technically sophisticated, manufactured
using high-quality materials and subject to many hours of testing in the factory. They
reect the state of the art and comply with recognised technical safety regulations.
However, there are still risks involved, even when the appliances are used as intended.
These are described below.
Live components may be exposed once the covers have been removed. Touching
these can lead to an electric shock. Disconnect the mains plug before removing any
covers. Work on the electrical system must only be performed by qualied electri-
cians.
When loading the appliance with an unsuitable load, poisonous or explosive vapours
or gases may be produced. This could cause the appliance to explode, and persons
could be severely injured or poisoned. The appliance may only be loaded with mate-
rials / test objects that do not emit any poisonous or explosive vapours when heated
up.
Operating without a tempering medium can cause the appliance to overheat and pose
a re hazard. Do not operate the water bath without a tempering medium. Always
observe the minimum ll level for the tray.
Depending on operation, the surfaces of the appliance and the chamber load may still
be very hot after the appliance is switched off. Touching these surfaces can cause
burns. Wear heat-resistant protective gloves or wait until the appliance cools down
after switching off before touching.
The drain valve can become overheated while emptying the water bath. Touching its
surface can cause burns. Use heat-resistant protective gloves to turn the drain valve
on/off or let the tempering medium cool down rst and empty the water bath when it
has reached a lukewarm temperature.
Hot steam can build up inside the appliance. You may be scalded when opening the lid
or coming into close contact with the surface of the water. Keep a safe distance away
from the water’s surface when opening the lid and when removing.
