NOTES:
1. Clearances – Recommended YORK clearances for peak per-
formance, reliable operation, and maintenance: Side to wall – 8';
Rear to wall – 8'; Control panel end to wall – 5'; Over the top –
no obstructions allowed; Two units side by side – 12', (walls
should be no higher than the unit).The area within the clearances
and under the unit(s) must be kept clean of clutter. Additional
height should be included to allow for snow accumulation for
units which are expected to operate at full load during the winter.
Reduced clearances may be used due to jobsite restrictions.
The unit(s) with optional controls will allow optimal operation pre-
venting the condenser pressure from exceeding the maximum
limit. The units will continue to operate without nuisance high
pressure cutout even though the airflow may be restricted at
these conditions.
2. Panel bottom to be punched in field to accommodate power wir-
ing conduit.
3. Use of isolators (optional) will increase height of unit approxi-
mately 6".
4. Drawings not to scale and are for planning purposes only. Con-
tact nearest YORK Sales Office for detailed drawings.

NOTES for Electrical Data for pages 12-15:
1. Minimum circuit ampacity (MCA) is based on 125% of the rated load amps for the largest motor plus 100% of the rated load amps for all
other loads included in the circuit, per N.E.C. Article 430-24. If a Factory Mounted Control Transformer is provided, add the following to
the system #1 MCA values in the YCA Tables: -17, add 10 amps; -28, add 9 amps; -40, add 5 amps; -46, add 4 amps; -58, add 3 amps.
2. Minimum Non-Fused Disconnect Switch size is based on a minimum of 115% of the sum of the RLAs for all the loads included in the circuit,
per N.E.C. 440-12A1. Available as factory-mounted option on units with single-point power supply.
3. Minimum Dual Element Fuse size is based on 150% of the largest motor RLA plus 100% of the remaining RLAs. (U.L. Standard 1995,
Section 36.1) Maximum Dual Element Fuse size is based on 225% of the maximum RLA plus 100% of the RLAs for all other loads included
in the circuit, per N.E.C. 440-22. Minimum fuse rating = 1.5 x Largest Compr RLA + Other Compr RLAs + (# fans) x Fan FLA. Maximum
fuse rating = 2.25 x Largest Compr RLA + Other Compr RLAs + (# Fans) x Fan FLA. These sizes are for field-supplied fuses.

5. Wire Range is the minimum and maximum wire size that can be accommodated by the unit wiring lugs. The (1), (2), or (3) preceding the
wire range indicates the number of termination points available per phase. The (1-2) preceding the wire range indicates that a single
double-barreled lug is available per phase that can accept up to two wires of the wire range specified. “(1) #1-600 or (2) #1-250”
indicates that a single lug is supplied and it will accept a single wire up to 600MCM or 2 wires up to 250MCM. Actual wire size and number
of wires per phase must be determined based on ampacity and job requirements using N.E.C. wire sizing information. The above
recommendations are based on the National Electrical Code and using copper connectors only. Field wiring must also comply with local
codes.
6. A ground lug is provided for each compr. system to accommodate field grounding conductor per N.E.C. Article 250-54. A control circuit
grounding lug is also supplied. Incoming ground wire range is #6 - 350 MCM (104 - 220 Tons)(334 - 810 kW).
7. The supplied disconnect is a “Disconnecting Means”as defined in N.E.C. 100.B, and is intended for isolating the unit from the available
power supply to perform maintenance and troubleshooting. This disconnect is not intended to be a Load Break Device.
8. All unit compressors have a part winding electrical configuration such that the indicated Locked Rotor Amps are Part Wind Locked Rotor

INSPECTION
Immediately upon receiving the unit, it should be in-
spectedfor possibledamage whichmay haveoccurred
duringtransit.Ifdamage is evident, itshouldbenoted on
the carrier’s freight bill. A written request for inspection
by the carrier’s agent should be made at once. See In-
struction50.15-NM for more information anddetails.
LOCATIONANDCLEARANCES
These units are designed for outdoor installations on
groundlevel, rooftop, or beside a building. The location
should be selected for minimum sun exposure and to
insureanadequatesupply of freshairforthe condenser.
Theunits must beinstalled with sufficientclearancesfor
airentrancetothecondenser coil, for air dischargeaway
fromthe condenser, and for servicing access.
In installations where winter operation is intended and
snowaccumulations areexpected,additionalheightmust
be provided to insure normal condenser air flow. (See
DIMENSIONSpages 10 and11).
FOUNDATION
The unit should be mounted on a flat and level founda-
tion, floor or rooftop, capable of supporting the entire
operatingweight oftheequipment.SeePHYSICAL DATA
pages8and 9 for operatingweight.If the unit iselevated
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,andthereciprocatingcompressors.
Ground Level Locations
Itis importantthat the units 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
mainbuilding foundation as noise and vibration may be
transmitted.
Mountingholesareprovidedinthesteel channel for bolt-
ingthe unitto its foundation. (See DIMENSIONS pages
10and 11).
Forgroundlevelinstallations,precautionsshouldbetaken
to protect the unit from tampering by or injury to unau-
thorizedpersons.Screwsand/or latches onaccesspan-
elswillpreventcasual tampering. However,furthersafety
precautions such as a fenced-in enclosure or locking
deviceson the panelsmay beadvisable. A tamperproof
kit is available as an option. Check local authorities for
safetyregulations.
Rooftop Locations
Chooseaspotwithadequatestructuralstrengthtosafely
supportthe entire weightof theunit and serviceperson-
nel. Care must be taken not to damage the roof.
Consult the building contractor or architect if the roof is
bonded.Roof installations should have wooden beams
(treated to reduce deterioration), cork, rubber or vibra-
tion isolators under the base to minimize vibration.
SHIPPINGBRACES
Twoshippingbrackets(typically galvanized steel)which
run diagonally along each side of the unit, must be re-
moved once the unit is mounted on its foundation. A
third bracket on the right rear of the unit should also be
removed.This bracket runs across thebottom rightcor-
ner of the unit behind the compressors.
SPRING ISOLATORS (OPTIONAL)
Whenordered,eight(8)springisolatorswillbefurnished.
1. Identify isolator and locate at proper mounting point
usingtable on page 18.
2. Block up equipment so as to install spring mounts
with pin on top of housing into Equipment Mounting
Holes.
3. Mounting Adjust Nut is inside the isolator mount lo-
cated just below the top plate of the mount. Turn nut
2turnsclockwise(down) to load spring mountateach
location.
4. Take two additional turns on Adjustment Nut of each
location.
5. Repeat step No. 3 as many times as necessary to
bringheight of isolator to proper height.
6. Take additionalturns on mounts at low side orcorner
tolevel the equipment.
COMPRESSORMOUNTING
The compressors are mounted on four (4) isolator pads

CHILLED LIQUID PIPING
GENERAL –Whenthe unit has been located in its final
position, the unit liquid piping may be connected. Nor-
malinstallationprecautions should beobserved in order
toreceivemaximumoperating efficiencies. Piping should
be kept free of all foreign matter. All liquid cooler piping
must comply in all respects with local plumbing codes
andordinances.
Sinceelbows,tees and valvesdecrease pump capacity,
all piping should be kept as simple as possible.
Handstop valvesshould be installed in all lines to facili-
tateservicing.
Piping to the inlet and outlet connections of the chiller
shouldincludehigh-pressurerubberhoseorpipingloops
to insure against transmission of water pump vibration.
Thisis optional andthe necessary componentsmust be
obtainedin thefield.
Drainconnectionsshould be provided atalllow points to
permitcompletedrainageof liquid cooler and pipingsys-
tem.
Asmallvalve or valvesshouldbe installed at thehighest
point or points in the chilled liquid piping to allow any
trapped air to be purged. Vent and drain connections
shouldbeextended beyond theinsulation to make them
accessible.
The piping to and from the cooler must be designed to
suit the individual installation. It is important that the
followingconsiderationsbeobserved:
1. Thechilled liquid piping system should be laid out so
that the circulating pump discharges directly into the
cooler. The suction for this pump should be taken from
the piping system return line and not the cooler.
2. Theinlet and outletcooler liquid connectionsizes are
givenon pages10 and 11.
3. A strainer, preferably 40 mesh, MUST be installed in
the cooler inlet line just ahead of the cooler.
4. All chilled liquid piping should be thoroughly flushed
to free it from foreign material before the system is
placed into operation. Use care not to flush any for-
eign material into or through the cooler.
5. As an aid to servicing, thermometers and pressure
gaugesshould be installed in the inlet and outlet wa-
terlines. One connection point (plugged) is provided
ineachcoolernozzle. Thermometers and gauges are
not furnished with the unit and are to be furnished by
othersuppliers.
6. The chilled liquid lines that are exposed to outdoor
ambients should be wrapped with a supplemental
heater cable and insulated to protect against freeze-
upduring low ambientperiods, and toprevent forma-
tionofcondensation on lines inwarmhumid climates.
7. A chilled water flow switch, (either by YORK or oth-
ers) MUST be installed in the leaving water piping of
the cooler. There should be a straight horizontal run
of at least 5 diameters on each side of the switch.
Adjust the flow switch paddle to the size of pipe in
which it is to be installed. (See manufacturer’s in-
structions furnished with switch). The switch is to be
wired to terminals in the control panel as shown in
theWIRINGDIAGRAM.
WARNING: Flow switch must not be used to stop and
start chilier. It is intended only as a safety
switch.
COMPRESSORINSULATION

ELECTRICALWIRING
LiquidChillers are shipped withall factory mountedcon-
trolswired for operation.
Field Wiring –Power wiring must be provided through
a fused disconnect switch to the unit terminals (or op-
tional molded case disconnect switch) in accordance
withN.E.C. or localcode requirements. Minimum circuit
ampacityandmaximumdualelementfusesizearegiven
on pages 12 - 15. A 115-1-60/50, 20 amp source must
besuppliedfor the control panelthrougha fused discon-
nect when a control panel transformer (optional) is not
provided.Referto WIRING DIAGRAM page 20.
Affiliatedapparatus, such asa chilledwater flow switch,
auxiliary contacts from the chilled water pump starter,
alarms,etc., should beinterlocked into thecontrolpanel
circuit.Thesefieldmodificationsmay be made asshown

MULTIPLE UNITS
Forincreasedcompressorprotectionandtoreducepower
inrush at start-up on multiple chiller installations, provi-
sions must be made to prevent simultaneous startup of
twoormoreunits.Also,somemethodmustbeemployed
to automatically cycle one or more of the units on or off
topermitmoreefficient operation atpartloadconditions.
A sequencing kit may be acquired through your local
YORKrepresentative.
RELIEF VALVES
An internal relief valve(s) is installed internally in each
compressor. A second integral internal relief valve is
built into the liquid line solenoid valve of each system.
Allrelief valves are resealable typesafety devices.

NOTES:
1. Field wiring to be in accordance with the current edition of the
National Electrical Code as well as all other applicable codes and
specifications.
2. Contacts must be suitable for switching 24VDC (gold contacts
recommended). Wiring shall not be run in the same conduit with
any line voltage wiring.
3. To cycle unit on and off automatically with contact shown, install
a cycling device in series with the flow switch (FLSW). See Note
2 for contact rating and wiring specifications.
4. To stop unit (Emergency Stop) with contacts other than those
shown, install the stop contact between terminals 5 and 1. If a
stop device is not installed, a jumper must be connected be-
tween terminals 5 and 1. Device must have a minimum contact
rating of 100VA at 115 volts A.C.
5. Contacts are rated at 115V, 100VA, resistive load only and must
be suppressed at load by user.
6. See installation, operation and maintenance manual.
7. Power factor correction capacitors may be installed on the chiller
electrical system (as shown) as a factory installed option.
8. Numbers along the right side of a diagram are line identification
numbers. The numbers at each line indicate the line number
location of relay contacts. An underlined contact location signi-
fies a normally closed contact. Numbers adjacent to circuit lines
are the circuit identification numbers.
