Danger to life due to electric shock!
An electric shock can result in death or serious injury.
– Ensure that the unit is voltage-free and isolated from the mains power supply. Ground and short circuit the unit, shield
neighbouring live components.
– The unit must be isolated from the mains power supply before disassembly or re-assembly.

Risk of personal injury and material damage!
The disassembly and re-assembly of the unit are not part of routine maintenance.
– The disassembly and re-assembly of the unit may only be carried out by qualified specialist personnel.
Risk of material damage when installing cooling registers!
The following must be taken into account when installing cooling registers:
– Close all hydraulic stop valves.
– Isolate all connections and ensure that the unit is leak-free with regard to water.
– Since the diameter of the cooling pipes is small, water may remain in the register after emptying. For safety reasons,
compressed air should be blown through the system to remove the remaining water.

Danger to life due to electric shock
The installation and connection of the unit may only be carried out by qualified specialist personnel. The electrical con-
nections must be carried out by a person who has proper professional training and experience in the relevant accident
prevention regulations, as well as other generally recognised safety and occupational health codes, with authorisation
to perform work on the unit.
Risk of injury due to electric shock, hot surfaces and potentially hot surface of optional auxiliary heater .
The unit must be fully isolated from the mains power supply before all maintenance and installation work and
opening the terminal compartment! The electrical connections must be carried out in accordance with the fol-
lowing wiring diagrams and must only be carried out by qualified electricians . The electrical connection must
be fully isolated until the final assembly!
– The flow and return pipes of the cooling register must be insulated .
– Observe the wiring diagrams for the cooling register DX signal connections .
– The air ducts behind the cooling register must be insulated .
The cooling registers DX contain nitrogen ex works with a pressure of 1 bar . Check the pressure prior to
assembly . Only use the register if the pressure is correct . Pressure that is too low indicates a possible leakage .
