Operating instructions

Detailed information for the connection and use of these interfaces
can be found in the operating manual of the respective LAUDA
interface module.
3.5 Options
The options installed in the device can be recognised on a sticker
underneath the rating plate.
A heater is possible as an option for all devices. This option is only
possible at the factory.
For these options, reinforced pumps are installed starting from the
VC 1200 (W) devices. This results in a greater installation height of
the device for the VC 1200 (W) and VC 2000 (W) devices.
Depending on the pump power, this option reduces the cooling
capacity by more than
200 W. This option is only possible at the
factory.
The device is only permitted to be installed outdoors if it is pro-
tected from weather influences (provide shelter or enclosure). Out-
door installation is possible as an option for the VC 5000 (W), VC
7000 (W) and VC 10000 (W) devices. This option is only possible
at the factory.
Expansion of the technical data
 The ambient temperature range is expanded to -20 … 40 °C.
Operation outdoors for outdoor temperature below 5 °C:
 Outdoor installation is configured: warning 349 device pre-
heating XX min.
The device shows this warning in the display after switching on
the device with the mains power switch. The preheating time
remaining for the compressor until it can be started is dis-
played. The compressor is preheated using its own heater. The
other components (pump and heater) are started immediately
when the device is switched from standby to operation.
 Outdoor installation is not
configured: warning 349 preheat
device!
The device shows this warning in the display for 10 seconds
after switching on the device with the mains power switch. It is
possible to start the device afterwards.
If the compressor is not preheated, this can result in
increased device wear or material damage in the
cooling system!
The use of demineralised (DM) water is possible as an option for
the optionally possible for the VC 600,
VC 1200 (W) and
VC 2000 (W) devices. This option is only possible at the factory.
