2.3 Electrical connection
Checking the safety equipment:
• Check the electrical connection for the correct voltage and fuses
(safety check according to VDE0701).
• Check that all safety equipment is complete and in full working order.
• Consult the operating manual for all information relating to safety (see
operating manual, chapter 3, “Safety”).
2.4 Water supply
2.4.1 Testing the water quality
Adhere to the water quality thresholds!
The quality of the cooling water (unprocessed water) and
demineralised water used has a considerable influence on the
performance and service life of the device.
− Unprocessed water of drinking water quality is used for cooling and for
the optional vacuum fitting.
− Demineralised water is used as feed water and for generating steam.
DIN 58951-2 states that the following thresholds must be adhered to:
(see operating manual, chapter 10, “Technical data”)
Unprocessed water quality
conductivity (at 20 °C)
< 300 µS/cm and ∑ alkaline earth ions ≤ 2.0 mmol/l,
corresponding to a total hardness of 11° dH
Demineralised water
conductivity (at 20 °C)
< 15 µS/cm and ∑ alkaline earth ions < 0.02 mmol/l
Tab. 1: Quality requirements for the water used
• Test the water quality and contact your local water company. If the
values exceed the water quality requirements specified above, you
must use a water softener system to prevent scaling.
2.4.2 Connecting the cooling water supply (X and E series)
On-site conditions:
− Pressure ≥ 1 bar
• Connect the cooling water supply using the hose supplied.
