Putting into Operation
4. Putting into Operation
4.1 Check the door and adjust if necessary
See page 68 .
4.2 Connecting
4.2.1 Power supply
Caution:
Observe the country-specific regulations when connecting (e. g. in Germany DIN VDE
0100 with residual current circuit breaker). Observe the connection and power ratings
(see nameplate).
The cooled incubator is intended for operation on an electrical power system with a system
impedance Z
max
at the point of transfer (service line) of a maximum of 0.292 ohms. The op-
erator must ensure that the cooled incubator 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.
Connecting power cable (see Fig. 5 on page 14 ).
4.2.2 External devices
Only appliances may be connected to the connections on the rear of the incubator (see Fig. 5
on page 14 ) whose interfaces comply with the requirements for safety extra-low voltage (e.g.
PC, laptop, printer).
4.2.3 Water connection
Fill the supplied water tank with water and
connect it with the enclosed tube to the
"H
2
O" connection on the rear of the chamber
( Fig. 9 ).
Water specifications Water specifications
For steam creation, use only:
►
steam distilled water (aqua dest)
or
►
Demineralised water (aqua dem) in
accordance with VDE 0510/DIN EN
50272; regulations must be strictly
adhered to (production conductivity ≤
10 µS/cm). Battery water in accordance
with VDE 0510 is available in larger
chemist's shops, super markets,
hardware stores and in the wholesale
trade. The standard VDE 0510/DIN EN
50272 has to be explicitly specified on
the label.
Otherwise, possible calcification in the steam generators, steam piping and peristaltic pumps
could affect the operability of the device.
Use only water with a pH value between 5 and 7.
