NOTES:
1. Clearances –Minimum YORK 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"
Failure to heed minimum clearances may result in reduced system performance, nuisance shutdowns and servicing
problems.
* 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. VIBRATION ISOLATORS (optional) will increase overall height of unit by approx. 6".
3. Drawings not to scale and are for planning purposes only. Contact nearest YORK office for detail drawings.

NOTES:
See page 12 for Electrical Illustrations.
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; -46, add 4 amps; -58, add 3 amps.
2. Minimum fuse size is based on 150% of the largest motor RLA plus 100% of the remaining RLAs (U.L. Standard 1995, Section 36.1). It is not
recommended in applications where brown-outs, frequent starting and stopping of the unit, and/or operation at ambient temperatures in
excess of 95°F is anticipated.
3. Maximum dual element fuse size is based on 225% maximum plus 100% of the rated load amps for all other loads included in the circuit, per
N.E.C.440-22.
4. The recommended disconnect switch is based on a minimum of 115% of the summation rated load amps of all the loads included in the circuit,
per N.E.C. 440-12A1.

5. Maximum HACR is based on 225% maximum plus 100% of the rated load amps for all loads
included in the circuit, per circuit, per UL 1995 Fig. 36.2.
6. The “INCOMING WIRE RANGE”is the minimum and maximum wire size that can be accommo-
dated by unit wiring lugs. The (1), (2), (3) or (4) preceeding the wire range indicates the number
of termination points available per phase of the wire range specified. The (1-2), (1-3),or (1-4)
preceeding the wire range indicates that a single multi-terminal lug is available per phase that
can accept from two (1-2) to four (1-4) wires of the wire range specified. “(1 ) #1-600MCM OR
(2) #1-250MCM”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 Electric Code and using copper connectors
only. Field wiring must also comply with local codes.
7. A ground lug is provided for each compressor system to accommodate field grounding con-
ductor per N.E.C. Article 250-54. A control circuit grounding lug is also supplied. Incoming
ground wire range is #6 - #2/0 (50 - 90 Tons) or #6 - 350 MCM (95 - 230 Tons).

Ground Level Locations
Itis importantthat theunits beinstalled ona 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
mainbuildingfoundations asnoiseand vibration maybe
transmitted.
Mountingholesareprovided inthesteelchannelfor bolt-
ing the unit to its foundation. (See DIMENSIONS).
Forgroundlevelinstallations,precautionsshouldbetaken
to protect the unit from tampering by or injury to unau-
thorizedpersons.Screws and/orlatchesonaccess pan-
elswillpreventcasualtampering.However,further safety
precautions such as a fenced-in enclosure or locking
deviceson thepanels may beadvisable. Atamperproof
kit is available as an option. Check local authorities for
safetyregulations.
Rooftop Locations
Chooseaspotwithadequate structural strengthtosafely
supportthe entireweight of theunit andservice person-
nel.Care must betaken nottodamage theroof.Consult
the building contractor or architect if the roof is bonded.
Roof installations should have wooden beams (treated
to reduce deterioration), cork, rubber or vibration isola-
tors under the base to minimize vibration.
SHIPPINGBRACES
Twoshipping brackets(typicallygalvanized 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 bracketruns acrossthe bottom rightcor-
ner of the unit behind the compressors.
SPRING ISOLATORS (OPTIONAL)
Whenordered (four)4 springisolators will befurnished.
1. Identify isolator and locate at proper mounting point
usingtable below.
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-
catedjust belowthe topplate ofthe mount.Turn nut

COMPRESSORMOUNTING
Thecompressors aremounted onfour (4)isolator pads
(one under each compressor foot). (See Fig. 4). The
mounting bolts are not to be loosened or adjusted at
installation.
CHILLED LIQUID PIPING
GENERAL –Whenthe unit has been locatedin itsfinal
position, the unit liquid piping may be connected. Nor-
malinstallation precautions shouldbe observed inorder
toreceivemaximumoperatingefficiencies.Pipingshould
be kept free of all foreign matter. All liquid cooler piping
must comply in all respects with local plumbing codes
andordinances.
COMPRESSORMOUNTINGPAD

Sinceelbows, tees andvalves decrease pumpcapacity,
all piping should be kept as straight and as simple as
possible.
Hand stop valve should be installed in all lines to facili-
tateservicing.
Piping to the inlet and outlet connections of the chiller
shouldincludehigh-pressurerubberhoseor piping loops
to insure against transmission of water pump vibration.
Thisis optionalandthe necessarycomponents must be
obtainedin thefield.
Drainconnections should beprovidedat all lowpointsto
permitcompletedrainage of liquidcoolerandpiping sys-
tem.
Asmall valve orvalvesshould beinstalledat the highest
point or points in the chilled liquid piping to allow any
trapped air to be purged. Vent and drain connections
shouldbe extended beyondthe insulation tomakethem
accessible.
Thepiping toand fromthe coolerMUST be designedto
suit the individual installation. It is important that the
followingconsiderationsbe observed:
1. Thechilled liquidpiping systemshould belaid outso
that the circulating pump discharges directly into the
cooler.Thesuctionforthis pump shouldbetakenfrom
the piping system return line and not the cooler.
2. Theinlet andoutletcooler liquidconnectionsizes are
givenon page 8.
3. A strainer, preferably 40 mesh, MUST beinstalled 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 andoutlet wa-
terlines. One connection point (plugged) is provided
ineachcooler nozzle. Thermometersandgauges 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 lowambient periods, andto preventforma-
tionof condensation onlinesin warm humidclimates.
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 chiller. It is intended only as a safety
switch.
COMPRESSORINSULATION
Inhighhumidityenvironments,compressorsweatingmay
be noted. In most applications, this is of no concern.
However,if itis undesirable,it is theresponsibility ofthe
installer to make provisions to field insulate the com-
pressor or install a factory insulation kit when they be-
come available. Contact YORK Factory Marketing for
availability.
