T

he appliances described in this manual are technically sophisticated, manufactured usin

g

high-quality materials and subject to many hours of testing in the factory. They contain the
latest technolo

g

y 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.

Warnin

g!

After removing covers, live parts may be exposed. You may receive
an electric shock if

y

ou touch these parts. Disconnect the mains plu

g

efore removing any covers. Only electrical technicians may work on

the electrical e

quip

ment of the appliances

.

Warning

!

When loading the appliance with an unsuitable load, poisonous or
exp

l

osive vapours or gases may be produced. This could cause the

Responsibility of the owne

r

T

he owner of the appliance

is responsible for the flawless condition of the appliance and for its proper operation in
accordance with its intended use (see pa

g

e 8);

is responsible for ensuring that persons who are to operate or service the appliance are

q

ualified to do this, have been instructed accordingly and are familiar with the operating

instructions at

hand;

ust know about the applicable guidelines, requirements and operational safety regula-

t

is responsible for ensuring that personal protective clothing is worn by operating person-

el, e.g. work clothes, safety shoes and protective gloves.

.

5Intended use

T

his appliance is exclusively intended for heating up non-explosive substances and objects.

A

ny other use is improper, and may result in hazards and damage.

T

he appliance is not explosion-proof (does not comply with the German workplace health &

s

afety regulation VBG 24). The appliance may only be loaded with materials and substances

which cannot form any toxic or explosive vapours at the set temperature and which cannot

explod

e, burst or ignite.

T

he appliance may not be used for drying, vaporising and branding paints or similar materi

-

als the solvents of which could form an explosive mixture when combined with air. If there
is any doubt as to the composition of materials, they must not be loaded into the appliance.

otentially explosive gas-air mixtures must not form, neither in the working chamber nor in

the direct vicinity of the appliance.

Appliances IFxx/UFxx for use as medical device

pp

or appliances IFxx and UFxx with extended overtemperature protection (option A6, recognis-

able due to standard DIN 12880-2007-Kl.:3.1 on the nameplate) subject to the 93/42/EEC
