UNIT IDENTIFICATION
EffectiveMay 1,1987, YORK introduced anew method
of unit identification (nomenclature). The new method
of identification does not reflect any change in unit de-
sign; only a change in nomenclature. This manual is
written based on the nomenclature used before May l,
1987. However, it is also fully applicable to units built
after May 1, 1987 which are identified by the later no-
menclature.Adescription of bothnomenclaturesis given
below. Also a cross-reference chart of models is pro-
vided for your convenience.

GENERAL INFORMATION
GENERAL DESCRIPTION
TheYCHA packaged liquid chillers are completely self-
contained outdoor units shipped ready for final job
installationrequiring only liquidconnections, power and
control wiring. They are designed primarily for central
station air conditioning applications with normal instal-
lations being on roof-tops or on ground level beside the
building.
CODE STATUS
Theunits aredesigned inaccordance withN.E.C., ANSI
B9.1, and ASME Codes.

NOTES:
1. Clearances – Minimum YORK required clearances to prevent condenser air recirculation and faulty operation of units are as follows:
Side to wall 8'–0"* Rear to wall 8'–0"* Control Panel End to wall 5'–0"* Top 50'–0"* Distance Between Adjacent units 12'–0"
* No more than one wall can be higher than the top of the unit. The area within the clearances shown above and area under the unit must
be kept clear of all obstructions that would impede free air flow to the unit. In installations where winter operation is intended and snow
accumulations are expected, additional unit height must be provided to insure full air flow.
2. Cooler liquid connection sizes (inlet & outlet) 6" victaulic standard (flanges OPTIONAL).
3. Dimensions are in inches.
4. Spring Isolators (OPTIONAL) will increase overall height of unit.

HANDLING
Theseunits are shippedas completely assembledunits
containing full operating charge, and care should be
taken to avoid damage due to rough handling.
The units are shipped without export crating unless it is
specified by Sales Order.
A unit should be lifted by inserting hooks through the
holes provided in the base rails. Spreader bars should
beused to avoidcrushing the unitwith the liftingchains.
(See Fig. 2.)
INSTALLATION
beneath windows or between structures where normal
operatingsounds maybe objectionable.The condenser
fansare propellertype andare not suitable nor intended
for use with duct work in the condenser air stream.
FOUNDATION
The unit should be mounted on a flat and level founda-
tion, floor or rooftop, capable of supporting the entire
operatingweight ofthe equipment. Ifthe unitis elevated
beyond the normal reach of service personnel, a suit-
able catwalk must be constructed around the unit. The
catwalk must be capable of supporting service person-
nel,theirequipment,andthereciprocatingcompressor(s).
Ground Level Locations
Itis important that theunits be installed on a substantial
base that will not settle. A one piece concrete slab with
footers extended below the frost line is highly recom-
mended. Additionally, the slab should not be tied to the
main building foundations as noise and vibration may
be transmitted.
Mounting holes (11/16" Dia.) 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 pre-
cautions such as a fenced-in enclosure or locking de-
vices on the panels may be advisable. Check local au-
thorities for safety regulations.
Rooftop Locations
Chooseaspotwith adequatestructuralstrengthto safely
support the entire weight of the unit and service per-
sonnel. If the unit is elevated on a steel structure, use
at least a sixpoint mount. Care must be taken not to
damage the roof. Consult the building contractor or ar-
chitect if the roof is bonded. Roof installations should
have wooden beams (treated to reduce deterioration),
cork, or rubber under the base to minimize vibration.
SPRING ISOLATORS (OPTIONAL)
When ordered, eight (8)* vibration isolators will be fur-
nished with each unit. They are of the level adjusting
spring type, manufactured by either Mason Industries
or Vibration Mounting & Controls, Inc.
*Four (4) on YCHA100
INSPECTION
Immediately upon receiving the unit, it should be in-
spectedfor possible damage which may have occurred
during transit. If damage is evident, it should be noted
on the carrier’s freight bill. A written request for inspec-
tionby the carrier’sagent should be made at once. See
“Instruction” Form 50.15-NM for more information and
details.
LOCATION
These units are designed for outdoor installations on
ground level, rooftop, or beside a building. The location
should be selected for minimum sun exposure and to
insurean adequate supplyof freshair forthe condenser.

Installation Instructions
1. Identify manufacturers of isolator and locate at
proper mounting point using appropriate table be-
low.
2. Block up equipment so as to install spring mounts
with pin on top of housing into Equipment Mounting
Holes.
3. MountingAdjustment Nut isinside theisolator mount
located just below the top plate of the mount. Turn
nut 2 turns clockwise (down) to load spring mount
at each location.
4. Take two additional turnson Adjustment Nut of each
mount.
5. Repeat step No. 3 as many times as necessary to
bring height of isolator to proper height.
6. Take additional turns on mounts at low side or cor-
ner to level the equipment.
