1.1 introduction
These operating instructions contain basic information which is to be complied with for instal-
lation, operation and maintenance. They must therefore be read and complied with by the fitter
and the responsible trained staff/operators before assembly and commissioning. All procedures
detailed in the manual, including tasks for installation, commissioning and maintenance must
only be performed by suitable trained and qualified personnel. They must be permanently avail-
able at the place where the system is used.
The manufacturer will not be liable for any injury or damage caused by incorrect installation,
commissioning, operation or maintenance resulting from a failure to follow the procedures and
instructions detailed in the manual.
1.2 Warranty
The warranty is limited to free replacement and shipping of any faulty part, or sub-assembly
which has failed due to poor quality or manufacturing errors. All claims must be supported by
evidence that the failure has occurred within the warranty period, and that the chiller has been
operated within the designed parameters specified.
All warranty claims must specify the model and serial number of the chiller. This information is
printed on the name plate, fitted on the door from the electrical cabinet.
The warranty will be invalid in case of any modification on the chiller which is not written
approved from STULZ.
To claim any warranty purpose the following conditions need to be satisfied:
The initial startup of the chiller has to be carried out by trained personnel authorized from
STULZ.
Only STULZ approved spare parts and liquids are allowed to be used.
All scheduled maintenance operations described in this manual must be performed accordingly
by trained and qualified personnel.
Not fulfilling at least one these conditions will automatically void the warranty.
