SECTION 1 – GENERAL CHILLER INFORMATION AND SAFETY

INTRODUCTION

YORK YLAA chillers are manufactured to the highest
design and construction standards to ensure high per-
formance, reliability and adaptability to all types of air
conditioning installations.
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
the 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 at-
tempting 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.

WARRANTY

Johnson Controls warrants all equipment and materi-
als against defects in workmanship and materials for a
period of eighteen months from date of shipment, or 12
months from date of start-up, whichever occurs first,
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.
All warranty claims must specify the unit model, serial
number, order number and run hours/starts. Model and
JOHNSON CONTROLS
serial number information is printed on the unit identi-
fication plate.
The unit warranty will be void if any modification to
the unit is carried out without prior written approval
from Johnson Controls.
For warranty purposes, the following conditions must
be satisfied:
• The initial start of the unit must be carried out by
trained personnel from an Authorized Johnson
Controls Service Center (see SECTION 6 – COM-
MISSIONING).
• Only genuine YORK approved spare parts, oils,
coolants, and refrigerants must be used.
• All the scheduled maintenance operations detailed
in this manual must be performed at the specified
times by suitably trained and qualified personnel
(see SECTION 10 – MAINTENANCE).
• Failure to satisfy any of these conditions will auto-
matically void the warranty (see Warranty on this
page).

HANDLING

These units are shipped as completely assembled units
containing full operating charge, and care should be
taken to avoid damage due to rough handling.
