Exceeding of the operating parameters!
Ensure that the operating parameters comply with the nominal values indicated on the name plate of the
chiller (voltage, frequency, air pressure, air temperature, ambient temperature etc.).
Prior to delivery, this chiller was thoroughly tested, packed and checked. Please verify the soundness of the chiller
during the initial start-up and check the perfect functioning during the first operating hours.
The initial start-up must be carried out by qualified personnel.
During the installation and operation of this device, all national regulations regarding electronics and

fixed and supported properly.
 Ensure that the condensate drain pipe is fixed in accordance with the provisions and that it is connected with a
collection system or a container.
 Ensure that the bypass system (if installed) is open and that the chiller is disconnected from the compressed-air
system.
 Ensure that the manual valve of the condensate drainage cycle is open.
 Ensure that the cooling-water flow and the cooling-water temperature are in accordance with the provisions (water-
cooled).
 Remove any packaging material and other items which may block the space around the chiller.
 Establish the mains connection (plug into socket).
• Start the chiller by switching on the main switch on the control panel (pos. 1).
• Make sure that the electronic control unit is switched on.
• Ensure that the power consumption complies with the values on the name plate.
• Ensure that the fan runs properly – wait for the first interventions (air-cooled).
• Wait until the dew point remains stable.
• Slowly open the air inlet valve.
• Slowly open the air outlet valve.
• Slowly close the central bypass valve of the system (if installed).
• Check the pipes for air leakage.
• Ensure the proper functioning of the condensate drain cycle (wait for the first condensate discharges).
