7.
Please check the device to ensure its
proper condition and operating safety
before each operation. If its condition
is not flawless, the device must not be
used and must be labelled accordingly.
8.
Before the cleaning and maintenance
of the device or before replacing parts,
the power plug must be pulled out.
9.
Signs and stickers must always be kept
in an easy-to-read condition and must
not be removed.
10.
The opening of the device and
repairs may only be performed by
authorized professionals.
11.
Only use nitrogen as protective gas.
Do not use flammable or toxic gases
under any circumstances. Please observe
the general safety and accident preven-
tion regulations when handling nitrogen.
12.
Only use approved gas pressure
bottles.
13.
When connecting the gas pressure
bottle to the device, be sure to check
the tightness of the feed tube. Please
make sure that the gas pressure bottle
cannot tip over.
14.
Never connect the gas bottle with-
out using a pressure reducer; the device
may be operated with a maximum
pressure of 5 bar (70 psi).
15.
Please close the gas supply, when
the device is not used. Do not operate
the device unattended.
16.
Be sure to provide for sufficient ven-
tilation in the work area.
17.
The pressure of the gas line must
not exceed 5 bar (70 psi).
18.
Do not keep any highly inflammable
substances within the immediate vicinity
of the device.
19.
Authorized operators: The operator
of the device must make the operating
instructions accessible to the operator
and must also make sure that s/he has
read and understood them. Only then
may the operator put the device into
operation.
20.
To prevent the ingress of water
into the device (e. g. splash water), the
device should be installed in a dry envi-
ronment.
21.
Please disconnect the device from
the mains when it is not used.
22.
To avoid the risk of getting caught,
only touch the lid at the handle.
23.
Do not operate the device if the
housing of the device is not closed and
screwed on.
24.
Unauthorized modifications and
changes are inadmissible for safety
reasons.
25.
The prescribed operating and main-
tenance conditions specified in these
operating instructions must be com-
plied with. Please observe the general
accident prevention regulations when
working with the PCU LED N
2
.
Please ensure before the commission-
ing that no damage has occurred during
transport. Check the housing for external
damages and control the glass plates on
the floor and at the lid of the polymer-
ization chamber. The lid is secured for
transport reasons. The transport locks
must be removed before the commis-
sioning of the device. Please ensure that
the indicated voltage on the type plate
corresponds to the voltage of the power
source. Insert the power cable into the
appliance socket and create a network
connection with the connection cable.
Attach the protective gas supply to the
connection of the pressure reducer of
the gas pressure bottle with the use of
5. Commissioning
the hose clamp. Establish a connection
to the device with the quick-lock cou-
pling. The pressure must not exceed
5 bars (70 psi).

The use of the protective gas allows for
the completion of the polymerization in an
atmosphere without oxygen. The protec-
tive gas replaces the air in the polymeriza-
tion chamber and thus reduces the oxygen
content in the polymerization space of the
PCU LED N
2
, which leads to the hardening
of components without an inhibition layer.
The protective gas supply is automatically
controlled when the polymerization pro-
cess starts. The flow rate is preset; the
adjustment can be changed at the con-
trol needle valve at the back of the device
(please observe the safety instructions).
6. Information on the use of the protective gas
The outlet pressure of the bottle can be
mounted to the pressure reducer of the
gas pressure bottle so that the flow is
changed without changing the control
needle valve. The gas flow is factory-set
The use of a flow meter is recommended
for monitoring the gas flow during opera-
tion. (Please refer to the instructions for
use of the relevant material for exact infor-
mation on type and flow rate.) The con-
nection pressure must be set to 5 bars.
