SECTION 1 - GENERAL CHILLER INFORMATION & SAFETY
INTRODUCTION
YORK YCAV0157-0267 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.

YORK International warrants all equipment and materi-
als against defects in workmanship and materials for a
period of eighteen months from date of shipment, unless
labor or extended warranty has been purchased as part
of the contract.
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
claims must be supported by evidence that the failure
has occurred within the warranty period, and that the
unit has been operated within the designed parameters
specified.
JOHNSON CONTROLS
All warranty claims must specify the unit model, serial
number, order number and run hours/starts. Model and
