Specification
GENERAL
The 47 - 60 Ton (165 - 210 kW) YCAL models are
shipped complete from the factory ready for installation
and use.
The unit is pressure-tested, evacuated, and fully charged
with Refrigerant-22 (HCFC-22) and includes an initial
oil charge. After assembly, a complete operational test
is performed with water flowing through the cooler to
assure that the refrigeration circuit operates correctly.
The unit structure is heavy-gauge, galvanized steel. This
galvanized steel is coated with baked-on powder paint,
which, when subjected to ASTM B117 1000 hour, salt
spray testing, yields a minimum ASTM 1654 rating of
“6”. Corrosion resistant wire mesh panels are added to
protect the condenser coil from incidental damage and
restrict unauthorized access to internal components.
Units are designed in accordance with NFPA 70 (Na
tional Electric Code), ASHRAE/ANSI 15 Safety code for
mechanical refrigeration, ASME, Listed and labeled with
Intertek Testing Services (ETL) and rated in accordance
with ARI Standard 550/590-2003.
COMPRESSORS
The chiller has suction-gas cooled, hermetic, scroll com
pressors. The YCAL compressors incorporate a compliant scroll design in both the axial and radial direction. All
rotating parts are statically and dynamically balanced. A
large internal volume and oil reservoir provides greater
liquid tolerance. Compressor crankcase heaters are also
included for extra protection against liquid migration.

Placement on a level surface of free of obstructions (including snow, for winter operation) or air circulation ensures rated performance, reli-
able operation, and ease of maintenance. Site restrictions may compromise minimum clearances indicated below, resulting in unpredictable
airflow patterns and possible diminished performance. YORK’s unit controls will optimize operation without nuisance high-pressure safety
cutouts; however, the system designer must consider potential performance degradation. Recommended minimum clearances: front to wall
– 6'; rear to wall – 6'; cooler end to wall – 4'0"; coil end to wall - 6'; top – no obstructions allowed; distance between adjacent units – 10'.
No more than one adjacent wall may be higher than the unit. 1" nominal deflection isolators (not shown) will increase overall unit height by
6".

NOTE:
Placement on a level surface of free of obstructions (including snow, for winter operation) or air circulation ensures rated performance, reli-
able operation, and ease of maintenance. Site restrictions may compromise minimum clearances indicated below, resulting in unpredictable
airflow patterns and possible diminished performance. YORK’s unit controls will optimize operation without nuisance high-pressure safety
cutouts; however, the system designer must consider potential performance degradation. Recommended minimum clearances: front to wall
– 6'; rear to wall – 6'; cooler end to wall – 4'0"; coil end to wall - 6'; top – no obstructions allowed; distance between adjacent units – 10'.
No more than one adjacent wall may be higher than the unit. 1" nominal deflection isolators (not shown) will increase overall unit height by

Application Data
UNIT LOCATION
The YCAL chillers are designed for outdoor installation.
When selecting a site for installation, be guided by the
following conditions:
1. For outdoor locations of the unit, select a place
having an adequate supply of fresh air for the con
denser.
2. Avoid locations beneath windows or between
structures where normal operating sounds may be
objectionable.
3. Installation sites may be either on a roof, or at ground
level. (See FOUNDATION.)
4. The condenser fans are the propeller-type, and
are not recommended for use with duct work in the
condenser air stream.
5. When it is desirable to surround the unit(s), it is
recommended that the screening be able to pass
the required chiller CFM without exceeding 0.1” of
water external static pressure.
for special installation requirements. Roof installations
should incorporate the use of spring-type isolators to
minimize the transmission of vibration into the building
structure.
GROUND LEVEL INSTALLATIONS – It is important that
-
the units be installed on a substantial base that will not
settle, causing strain on the liquid lines and resulting in
possible leaks. A one-piece concrete slab with footers
extending below the frost line is highly recommended.
Additionally, the slab should not be tied to the main
building foundation, as noises will telegraph.
Mounting holes (11/16” diameter) are provided in the
steel channel for bolting the unit to its foundation. See
DIMENSIONS.
For ground level installations, precautions should be
taken to protect the unit from tampering by or injury
to unauthorized persons. Screws on access panels
will prevent casual tampering; however, further safety
precautions, such as unit enclosure options, a fenced-in
enclosure, or locking devices on the panels may be ad
visable. Check local authorities for safety regulations.
-
6. Protection against corrosive environments is avail
able by supplying the units with either copper fin,
cured epoxy-dipped, or epoxy-coated fins on the
condenser coils. The epoxy-dipped or epoxy-coated
coils should be offered with any units being installed
at the seashore or where salt spray may hit the
unit.
In installations where winter operation is intended and
snow accumulations are expected, additional height
must be provided to ensure normal condenser air
flow.
Recommended clearances for units are given in DI
MENSIONS. When the available space is less, the
unit(s) must be equipped with the discharge pressure
transducer option to permit high pressure unloading in
the event that air recirculation were to occur.
FOUNDATION
The unit should be mounted on a flat and level founda
tion, ground or roof, capable of supporting the entire
operating weight of the equipment. Operating weights
are given in the PHYSICAL DATA tables.
ROOF LOCATIONS – Choose a spot with adequate
structural strength to safely support the entire weight
of the unit and service personnel. Care must be taken
not to damage the roof during installation. If the roof is
“bonded”, consult the building contractor or architect
-
CHILLED LIQUID PIPING
The chilled liquid piping system should be laid out so
that the circulating pump discharges into the cooler.
The inlet and outlet cooler liquid connections are given
in DIMENSIONS.
Hand stop valves are recommended for use in all lines
to facilitate servicing. Drain connections should be
provided at all low points to permit complete drainage
of the cooler and system piping. Additionally, a strainer
(40 mesh) is recommended for use on the INLET line
to the cooler.
Pressure gauge connections are recommended for
installation in the inlet and outlet water lines. Gauges
are not furnished with the unit and are to be furnished
by other suppliers.
The chilled liquid lines that are exposed to outdoor am
bients should be wrapped with a supplemental heater
-
cable and covered with insulation. As an alternative,
ethylene glycol should be added to protect against
freezeup during low ambient periods.
A flow switch is available as an accessory on all units.
The flow switch (or its equivalent) must be installed in
the leaving water piping of the cooler and must not be

and ease of maintenance.
2. Piping and wiring shown is for reference use only
and is not in accordance with any national or local
standards.
3. All wiring and piping must comply with applicable
local and national codes.
4. All wiring and piping must follow standard piping
techniques as discussed in the ASHRAE handbook.
5. A strainer with a mesh size between .5 and 1.5 mm
is recommended upstream of the heat exchanger to
prevent clogging.
