GENERAL DESCRIPTION
YORK YCWJ45EE0  YCWJ99MJ0 and YCRJ45E00 
YCRJ99M00 Series Packaged Liquid Chillers are of the
semi-hermetic type. Each unit includes dual refrigerant
circuits, accessible hermetic motor-compressors, a di-
rect expansion type liquid cooler, a shell and tube con-
denser, refrigerant piping and feed controls, a micropro-
cessor control center, and power panel.
Each unit is fully assembled on a steel base, piped,
insulated, wired and are fully charged with refrigerant.
YCR models for remote condenser application are fur-
nished less condenser, and with a refrigerant holding
charge.
CODE STATUS
The units are designed in accordance with U.L. (200,
230, 460-3-60), N.E.C., ASHRAE/ANSI STANDARD 15,
and ASME Codes.

WARNING
HIGH VOLTAGE
is used in the operation of this equipment.
DEATH OR SERIOUS INJURY
may result if personnel fail to observe safety precautions.
Work on electronic equipment should not be undertaken unless the individual(s) have been trained in
the proper maintenance of equipment and is (are) familiar with its potential hazards.
Shut off power to equipment before beginning work and follow lockout procedures. When working
inside equipment with power off, take care to discharge every capacitor likely to hold dangerous
potential.
Be careful not to contact high voltage connections when installing or operating this equipment.
LOW VOLTAGE
DO NOT be misled by the term low voltage.
Voltages as low as 50 volts may cause death.
