Memmert UE 200 User manual
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.

For
correct
operation
and
uniform
temperature
distribution
it
is
essential
to
maintain
free
air
circulation
throughout
the
oven.
The
contents
of
the
oven
should
therefore
not
be
packed
tightly
nor
should
they
be
placed
directly
against
any
of
the
heating

either
to
the
sides,

or

of
the
oven.
(Note
the
loading
diagrams
on
ihe

When
putting
the
shelves
into
the
apparatus
please
bear
in
mind
that
there
is
a
little
air
gap
between
the
rear
of
the
working
chamber
and
the
shelf
in
order
to
permit
better
air
circulation.
For

in
certain
situations
where,
for

the

is

is
fully
open
it
is
possible
that
the

In
order

it
may
be

Cleaning
By
regular
cleaning
of
the
easy
to
clean
interior,
residues
are
avoided
which
at
continuous
influence
can
impair
the
outfit
and
function
of
the
oven.
The
unit
can
be
cleaned
with
commercial
stainless
steel
cleaning
agent.
Please
note
that
objects
liable
to
rust
must
not
be
placed
into
the
interior.
Rust
sediments
lead
to
contamination
of
the
interior
or
external
casing.
If
rust
stains
caused
by
contamination
occur
on
the
interior
surface,
the
affected
areas
must
be
cleaned
and
polished
immediately.
