GENERAL CHILLER INFORMATION & SAFETY
INTRODUCTION
YORK YCAV0267-0527 chillers are manufactured to
the highest design and construction standards to ensure
high performance, reliability and adaptability to all types
of air conditioning installations.
The unit is intended for cooling water or glycol solu-
tions and is not suitable for purposes other than those
specified in this manual.
Rigging and lifting should only be done by a profes-
sional rigger in accordance with a written rigging and
lifting plan. The most appropriate rigging and lifting
method will depend on job specific factors, such as the
rigging equipment available and site needs. Therefore,
a professional rigger must determine the rigging and
lifting method to be used, and it is beyond the scope of
this manual to specify rigging and lifting details.
This manual contains all the information required for
correct installation and commissioning of the unit, to-
gether with operating and maintenance instructions. The
manuals should be read thoroughly before attempting
to operate or service the unit.
All procedures detailed in the manuals, including in-
stallation, commissioning and maintenance tasks must
only be performed by suitably trained and qualified
personnel.
The manufacturer will not be liable for any injury or
damage caused by incorrect installation, commission-
ing, operation or maintenance resulting from a failure
to follow the procedures and instructions detailed in
the manuals.

The warranty is limited to parts only replacement and
shipping of any faulty part, or sub-assembly, which has
failed due to poor quality or manufacturing errors. All

specified.
All warranty claims must specify the unit model, serial
