This appliance is exclusively intended
for heating up non-explosive sub-
stances and objects. Any other use is
improper and may result in hazards
and damage.
The appliance is not explosion-proof
(does not comply with the German oc-
cupational health and safety regulation
VBG 24). The appliance may only be
loaded with materials and substances
which cannot form any toxic or explo-
sive vapours at the set temperature
and which cannot explode, burst or
ignite.
The appliance may not be used for the
drying, evaporation and burning-in of
paints or similar materials, the solvents
of which could form an explosive mix-
ture when combined with air. If there
is any doubt as to the composition of
materials, they must not be loaded into
the appliance. Potentially explosive gas-
air mixtures must not form, neither in
the working chamber nor in the direct
vicinity of the appliance.

2.3 Function
Appliances of the UN... and
IN
... type series feature
natural circulation (convec-
tion). For the UF
... and IF...
type series, air is circulated
by a fan at the working
chamber rear panel Fig. 3 ,
No. 1). It increases the air
flow and provides stronger
horizontal forced air
circulation than natural
convection.
In both the convection and
fan ventilated appliances,
supply air (2) is preheated
in a pre-heating chamber
(3). Through the ventilation
slits in the side panel of the
working chamber, the pre-
heated air is introduced into
the interior of the chamber.
The supply and exhaust air
(5) volume (air change) is
controlled by the air flap
(4) on the rear panel of the
appliance.
2.4 Material
For the outer housing, MEMMERT deploys stainless steel (Mat.No. 1.4016 – ASTM 430) and
for the interior, stainless steel (Mat.No. 1.4301 – ASTM 304) is used, which stands out through
its high stability, optimal hygienic properties and corrosion-resistance towards many (but not
all!) chemical compounds (caution for example with chlorine compounds).
The chamber load for the appliance must be carefully checked for chemical compatibility with
the materials mentioned. A material resistance table can be requested from the manufacturer.
2.5 Electrical equipment
► Operating voltage and current consumption: See nameplate
► Protection class I, i.e. operating insulation with PE conductor in accordance with EN 61010
► Protection type IP 20 acc. to EN 60 529
► Interference suppression acc. to EN 55011 class B
► Appliance fuse: Fusible link 250 V/15 A quick-blow
► The temperature controller is protected with a miniature fuse 100 mA (160 mA at 115 V)

2.6 Connections and interfaces
2.6.1 Electrical connection
This appliance is intended for operation on an electrical power system with a system imped-
ance Z
max
of a maximum of 0.292 ohm at the point of transfer (service line). The operator
must ensure that the appliance is operated only on an electrical power system that meets
these requirements. If necessary, you can ask your local energy supply company what the
system impedance is.
Observe the country-specific regulations when connecting (e.g. in Germany
DIN VDE 0100 with residual current circuit breaker).
2.6.2 Communication interface
The Ethernet interface is intended for appliances which meet the requirements of IEC 60950-1.
Via Ethernet interface, the appliance can be
connected to a network to read out protocol
logs with AtmoCONTROL, the optional
appliance software. The Ethernet interface is
located on the rear of the appliance (Fig. 4 ).
For identification purposes, each appliance
connected must have its own unique IP ad-
dress. Setting the IP address is described on
page 38.
With an optional USB to Ethernet converter,
the appliance can be directly connected to a
computer / laptop (see Optional accessories
on page 16).
2.7 Designation (nameplate)
The nameplate (Fig. 5) provides information about the appliance model, manufacturer and
technical data. It is attached to the front of the appliance, on the right side under the door
(see page 10).
