 Setup and description

2.2 Function
Appliances of the UNxx and
INxx type series feature
natural circulation (convec-
tion). For the UFxx and IFxx
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.

2.3 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.

Check the chamber load for chemical compatibility with the materials of the appliance
(see page 11).
Insert the sliding steel grids or sliding shelves. The maximum number or grids / shelves and the
load capacity are specified in the technical data overview on page 13.
The chamber must not be
loaded too tightly, so that
proper air circulation in the
working chamber is guaran-
teed. Do not place any
chamber load on the floor,
touching the side walls or
right below the ceiling of the
working chamber (Fig. 14, see
also the "correct loading"
sticker on the appliance).
In case of improper loading
(chamber loaded too tightly),
the set temperature may Fig. 14 Correct placement of the chamber load
be exceeded or it may take
longer until it is reached.
To achieve the correct heating capacity, the type of slide-in unit used – Grid or Shelf –
must be set in the menu under SETUP (see page 39).

5.5 Temperature monitoring
The appliance is equipped with a double overtemperature protection (mechanical/electronic)
in accordance with DIN 12 880. This serves to avoid damage to the chamber load and/or ap-
pliance in case of a malfunction:
Ź Electronic temperature monitoring (TWW/TWB)/ (TWB only if equipped with a second tem-
perature sensor, option A6)
Ź mechanical temperature limiter (TB)

Downloaded from www.Manualslib.com manuals search engine
 Operation and control

5.5.1 Electronic temperature monitoring

The monitoring temperature of the electronic temperature monitoring is measured via the
Pt100 temperature sensor in the interior of the chamber. The type of temperature monitoring
(TWW/TWB) and the monitoring temperature are set in menu mode in the Setup display (see
page 38). The setting made applies to all operating modes.
If the manually set monitoring temperature is exceeded, temperature monitoring takes over
temperature control and begins to regulate the monitoring temperature (TWW, Fig. 17) or
switches off the heating (TWB, Fig. 18).
The two types of temperature monitoring are only available for appliances equipped with
a second temperature sensor (option A6). For appliances with only one temperature
sensor, only TWW is available.

7.5 Calibration
The appliances are temperature calibrated and adjusted at the factory. In case readjustment
should be necessary later on – for example due to influence of the chamber load – the ap-
pliance can be calibrated customer-specifically using three calibration temperatures of your
choice:
Ź Cal1 Temperature calibration at low temperature
Ź Cal2 Temperature calibration at medium temperature
Ź Cal3 Temperature calibration at high temperature
To guarantee perfect control, we recommend to calibrate the appliance once a year.

For temperature adjustment, you will need a calibrated reference measuring device.

Caution!
Danger of cuts due to sharp edges. Always wear gloves when wor-
king in the chamber interior.

8.1.1 Working chamber and metal surfaces

Regular cleaning of the easy-to-clean working chamber prevents build up of material remains
that could impair the appearance and functionality of the stainless steel working chamber
over time.
The metal surfaces of the appliance can be cleaned with normal stainless steel cleaning
agents. Make sure that no rusty objects come into contact with the working chamber or with
the stainless steel housing. Rust deposits can lead to an infection of the stainless steel. If rust
spots should appear on the surface of the working chamber due to impurities, the affected
area must be immediately cleaned and polished.
8.1.2 Plastic parts
Do not clean the ControlCOCKPIT and other plastic parts of the appliance with caustic or
solvent-based cleaning agents.
8.1.3 Glass surfaces
Glass surfaces can be cleaned with a commercially available glass cleaner.

8.2 Regular maintenance

Once a year, grease the moving parts of the doors (hinges and lock) with thin silicone grease
and check that the hinge screws are not loose.
To guarantee perfect control, we recommend to calibrate the appliance once a year (see page
42).
8.3 Repairs and service
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. Any work inside
