SECTION 1 - GENERAL CHILLER INFORMATION AND SAFETY
INTRODUCTION
YORK YCIV0157 through 0397 chillers are manufac-
tured 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 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.
