7.
Ensure that unqualified persons, especially children, do not have access to the unit. Only quali-
fied persons or persons who have been authorized and instructed by laboratory owners are entitled
to work with the unit. Before commissioning the unit, the user must read the operating instructions,
follow it and contact the manufacturer in the case of obscurities.
8.
Only start the unit if the cover and the drain cock are closed. A cover protection provides pro-
tection from injuries caused by the agitator. If the protection fails (the agitator does not stop imme-
diately if the cover is open) turn off the unit immediately and send it to the manufacturer for servic-
ing.
9.
During the melting phase, the unit and even the surface of the device’s casing will heat up.
However, as long as the cover is closed, there is no danger of burning. Nevertheless, avoid any con-
tact. The duplicating material can reach a maximum temperature of 97 °C (206.6 °F), which could
cause scalds. Therefore, never open the drain cock at this temperature. Do not throw clots of du-
plicating material into the hot material because hot splashes could cause injuries (especially pro-
tect the eyes!).
10.
The unit has three over-temperature protections (one of them operates independently of the
microprocessor). If this independent protection actuates, the unit cannot be used anymore and
must be send to the manufacturer. Do not try to bridge this prevention system because, at normal
operation, it should never actuate. If it actuates, there is a serious problem that must be eliminated.
Otherwise, in the extreme case, danger of fire exists.
11.
The unit is equipped with a time pre-selection. Electric heating devices (as the EDG 1) should
never be used unsupervised. The unit has several safety circuits. In any case, you use the time pre-
selection at your own risk and without claim for liability against the manufacturer. In the case of a
power outage, for safety reasons the time pre-selection and the normal function of the unit are
stopped. When the power returns, the unit will be in the stand-by mode, which means without fur-
ther function.
12.
The unit is equipped with a no load protection. If a unit is started unintentionally without load or
with insufficient load, it will turn off and switch to the error mode (“E” is displayed). This problem can
only be resolved by turning off the unit and allowing it to cool down. In the error mode all functions
are blocked. The unit has three temperature sensors for control (independent of the over-
temperature protection). If one of the sensors is defect, the unit is also in the error mode but cannot
be reset and re-started. The unit must be sent to the manufacturer.
13.
Transport the unit carefully and only when it is cooled down. Avoid shocks and hits because due
the high weight the cup could be deformed. Please regard also the information about transport
and dispatch in section 7 of this manual.
