Introduction
IntroductionIntroduction
Introduction
These operating instructions have been drawn up by KKT chillers on the basis of the Machinery
Directive 006/4 /EC. They contain all important information and instructions for the installation
and safe operation of the refrigerating machine (chiller). It also contains advice on how to prevent
or correct faults.
Please allow yourself sufficient time to read through these instructions carefully and to digest all
the information this document contains. If you have any further questions, please contact the
KKT chillers Service Team using the contact details provided.
If properly used for its intended use and correctly maintained, the chiller ensures sustained, fault-
free operation. The methods and procedures described in these instructions should help you to
detect problems early and to take appropriate countermeasures.
If you keep to the maintenance programme described you ensure the reliability and safety of the
machine. You also keep the operating costs low and at the same time increase the life of the
components.
To ensure that the performance of your chiller is not impaired, we recommend that you only use
original spare parts purchased from KKT chillers. In this way you ensure the reliability and quality
of the machine.
KKT chillers reserves the right to change technical details without prior notice. The illustrations in
this document are not to scale!
As the Compact-Line units can be adapted to specific projects, this document only contains
information that is generally valid for all units in the series.
All project-specific data is enclosed with the unit in separate summary documentation.
