2.2 Product Safety and Dangers
The units described in this manual are technically sophisticated, manufactured using high-
quality materials and subject to many hours of testing in the factory. They reflect the state
of the art and comply with recognised technical safety regulations. However, there are still
risks involved, even when the units are used as intended. These are described below.
DANGER
Risk of electric shock due to ingress of liquids
Penetration of liquid into the appliance can cause electric shocks and short circuits.
– Protect the appliance from splashing water.
– Switch off the appliance and disconnect the mains plug before carrying out any
cleaning and maintenance work.
– The appliance must not be wet cleaned and disinfected. Allow the appliance to dry
completely before putting it back into operation.
– When loading the chamber with wet material, insert the drip tray provided for the
appliance size.
DANGER

3.2 Description of Function
UFTS-type appliances feature forced ventilation (convection). The pipe is encased by an
air jacket which preheats the fresh air. Incoming fresh air is supplied to the air jacket and
pushed into the air jacket by a fan. Fresh air flows into the chamber via ventilation slots in
the pipe. The exhaust air outlet is on the top of the appliance ⑧.
The appliance may be equipped with a mutual door locking system that prevents the
door(s) from being opened on the cleanroom side and the greyroom side simultaneously
(see }6.2Opening the Door).

3.3 Materials
For the outer housing, MEMMERT processes stainless steel (Mat. No. 1.4016 – ASTM 430)
for the chamber, stainless steel (Mat. No. 1.4301 – ASTM 304) is used, which stands out
through its high stability, optimal hygienic properties and corrosion-resistance to many
(but not all) chemical compounds (caution must be exercised with chlorine compounds,
for example).
The chamber load of the appliance must be carefully checked for chemical compatibility
with the above materials. A material resistance table can be requested from the
manufacturer.

3.5 Connections and Interfaces
3.5.1 Electrical Connection
This unit is designed for operation on an electrical power system with a maximum system
impedance Zmax at the point of transfer (service line) of 0.292 Ohm. The operator must
ensure that the unit is only operated on an electrical power system that meets these
requirements.
If necessary, ask your local utility company what the system impedance is. Observe the
country-specific regulations when making connections (e.g. in Germany DIN VDE 0100
with earth leakage circuit breaker).
3.5.2 Communication Interfaces
The communication interfaces are intended for appliances which meet the requirements of
IEC60950-1.
Ethernet interface
iYou will find a description of how to transfer programs via Ethernet in the AtmoCONTROL
software manual.

13 D39059 02/2024
The unit can be connected to a network via the Ethernet interface, so that you can transfer
programmes created with the AtmoCONTROL software to the unit and export logs.
For identification purposes, each unit connected must have its own unique IP address. A
description of how to set the IP address is provided in chapter }8.3.2 IP Address and
Subnet Mask.
The unit can be directly connected to a computer / laptop using an optional USB to
Ethernet converter (see }3.10Scope of Delivery).
USB interface
The unit comes with a USB port as standard in accordance with the USB specification.
With this you can:
■transfer software stored on a USB storage medium to the unit
(see }8.6Programme)
■export logs from the unit to a USB storage medium
(see }8.8Log)
■transfer user ID data stored on a USB storage medium to the unit
(see }8.9USER ID)
The USB port is located on the right of the ControlCOCKPIT.
