1.1 Introduction

York YS 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 units are intended for cooling water or glycol

solutions and are not suitable for purposes other than

This manual and the Control System Operating

Instructions contain all the information required for

correct installation and commissioning of the unit,

together with operating and maintenance instructions.

The manuals should be read thoroughly before

The manufacturer will not be liable for any injury or

commissioning, operation or maintenance resulting

from a failure to follow the procedures and instructions

detailed in the manuals.

1.2 Warranty

York International warrants all equipment and materials

against defects in workmanship and materials for one

year from initial start-up, or eighteen months from

delivery (whichever occurs first) unless extended

warranty has been agreed as part of the contract.

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 unit has been

operated within the designed parameters specified.

All warranty claims must specify the unit model, serial

number and order number.

The unit warranty will be void if any modification to the

unit is carried out without prior written approval from

York International.

For warranty purposes, the following conditions must be

satisfied:

The initial start of the unit must be carried out by trained

personnel from an Authorised York Service Centre.

Only genuine York approved spare parts, oils and

refrigerants must be used.

All the scheduled maintenance operations detailed in

suitably trained and qualified personnel.

Failure to satisfy any of these conditions will

automatically void the warranty.
