Product Safety And Dangers; Requirements Of The Operating Personnel - Memmert UN PLUS Series Operating Instructions Manual

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 contain the
latest technology 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.
Warning!
After removing covers, live parts may be exposed. You may receive
an electric shock if you touch these parts. Disconnect the mains plug
before removing any covers. Only electrical technicians may work on
the electrical equipment of the appliances.
Warning!
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 people could be severely injured or
poisoned. The appliance may only be loaded with materials/test
objects which do not form any toxic or explosive vapours when
heated up (see also chapter "Intended use" on page 8).
Warning!
Depending on operation, the surfaces in the working chamber
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.
To do so, pull the handle bar until the door springs open into its
ventilating position (see page 21).
Warning!
In case of appliances of a certain size, you can get accidentally
locked in, which is life-threatening. Do not climb into the appliance!

1.3 Requirements of the operating personnel

The appliance may only be operated and maintained by persons who are of legal age
and have been instructed accordingly. Personnel who are to be trained, instructed or who
are undergoing general training may only work with the appliance under the continuous
supervision of an experienced person.
Repairs may only be performed by qualified electricians. The regulations in the separate service
manual must be observed.
