If the chiller is stored for longer than 12 months, please contact the manufacture before
starting up the chiller again to check the condition of the machine parts, particularly the elec-
trical components.
See Chapter 6.5.2 (Temporary decommissioning).
5. LOCATION AND INSTALLATION
5.1 CHOOSING A LOCATION
Install the chiller in a protected dry area, free of fumes, dust or flammable vapours that is not subject
to an explosive hazard. The atmosphere must be free of any constituents that may impair the proper
functioning of the chiller.
A suitable area must be found in which a temperature of not less than +2 ± C and definitely not more than +40 ± C
can be guaranteed at any time of the year while the machine is operating. If you wish to operate the chiller at am-
bient temperatures of less than +2 ± C or more than +40 ± C, please contact the manufacturer in connection with the
necessary adaptations.
We recommend that appropriate ventilation should be provided. Operating the chiller heats up the area in which it
is installed. This applies particularly to chillers with a standard air-cooled condenser.
So as not to impair the cooling capacity of the chiller, we recommend protecting it against direct sunlight. You
should avoid connecting the axial ventilators to air ducts as they do not have sufficient compression.
Higher ambient temperatures than those given as a reference value in the data sheet reduce the cooling capacity.
The chiller should be installed on a horizontal and level surface that is capable of absorbing the compre ssive load of
the chiller. Larger chillers have holes at the ends of the supporting rails so that they can be fastened to the floor.
When the chiller is installed outside, it should be protected against any atmospheric influences. Please consult the
manufacturer for further details.
Position the chiller so that the instrument displays can be read easily and the controls can be easily accessed.
Allow sufficient space for the possible installation of further components.
There must be sufficient free space above the chiller to ensure that air can flow freely to cool the condenser.
