Congratulations

on

your

choice

of

a

MEMMERT

Oven!

Manufactured

in

Germany

using

the

latest

production

techniques

and

_

finest

materials

available,

you

now

posses

a

technically

superior

and

fully

developed

product.

Your

oven

has

already

been

under

extensive

testing

in

our

factory.

For

correct

operation

of

the

equipment

it

is

essential

to

observe

the

operating

and

maintenance

instructions

below.

This

will

ensure

that

your

equipment

will

give

many

years’

satisfactory

service.

Explanation

of

signs!

These

signs

refer

to

a

hazard

and

indicate:

Note

the

Operating

Instructions!

Generai

safety

instructions.

The

physical

and

chemical

properties

of

your

load

(e.g.

inflammation

temp.

etc.)

have

strictiy

to

be

observed,

as

otherwise

considerable

damages

(load,

oven,

surroundings

of

apparatus)

can

appear..

__

Please

note

that the

Memmert

ovens

described

here

are

not

explosion-proof

(they

do

not

conform

to

Occupational

Association

Regulation

VBG

24).

They

are

therefore

unsuitable

for

drying,

evaporating

or

burning-in

of

enamels

or

similar

substances

whose

solvent

may

form

an

inflammable

mixture

together

with

air.

There

must

be

no

possibility

for

inflammable

or

explosive

gas/air

mixtures

to

form

either

inside

the

cabinet

or

in

the

immediate

neighbourhood

of

the

equipment.

Severe

dust

formation

in

the

interior

and/or

in

the

surroundings

of

the

cabinet

may

lead

to

deposits

of

fine

dust

inside

the

equipment

which

can

result

in

short-circuits.

Adequate

precautions

should

be

taken

against

excessive

dust

formation.

Cleaning

By

regular

cleaning

of

the

easy

to

clean

residues

are

avoided

which

at

agent.

Please

note

that

objects

liable

to

caused

by

contamination

occur

on

surface,

the

affected
