Fan guards must be fi tted at all times and not removed unless the power supply has been isolated. If ductwork is to be fi tted, requiring the wire fan guards to be re moved, alternative safety measures must be taken to protect against the risk of injury from rotating fans.
Sharp Edges
The fi nning on the air cooled con dens er coils has sharp metal edges. Reasonable care should be taken when working in contact with the coils to avoid the risk of mi nor abra sions and lac er a tions. The use of gloves is recommended.
Refrigerants and Oils
Refrigerants and oils used in the unit are generally non­toxic, non-fl ammable and non-corrosive, and pose no spe cial safety hazards. Use of gloves and safety glass es are, however, recommended when working on the unit. The build up of refrigerant vapor, from a leak for ex-
am ple, does pose a risk of asphyxiation in confi ned or enclosed spac es and attention should be given to good ven ti la tion.
High Temperature and Pressure Cleaning
High temperature and pressure cleaning methods (e.g. steam cleaning) should not be used on any part of the pressure system as this may cause operation of the pres­ sure relief device(s). Detergents and solvents which may cause corrosion should also be avoided.
EMERGENCY SHUTDOWN
In case of emergency the electrical option panel is fi t ted with an emergency stop switch CB3 (Circuit Break er
3). Separate Circuit Break ers, CB1 (Sys tem 1) and CB2 (Sys tem 2), can also be used to stop the re spec tive sys­ tem in an emer gen cy. When op er at ed, CB3 re moves the elec tri cal supply from the con trol sys tem, thus shut ting down the unit.

INTRODUCTION

YORK YCAS chillers are designed for water or wa­ ter-glycol cooling. All units are designed to be lo cat ed outside on the roof of a building or at ground level.
The units are completely assembled with all in ter con ­nect ing refrigerant piping and internal wiring, ready for eld installation.
Prior to delivery, the unit is pressure tested, evacuated, and fully charged with refrigerant and oil in each of the two independent refrigerant circuits. After assembly, an operational test is performed with water fl owing through the evaporator to ensure that each refrigerant cir cuit operates correctly.
The unit structure is manufactured from heavy gauge, galvanized steel. All external structural parts are coat ed with “Desert Sand” baked-on enamel powder paint. This provides a fi nish which, when subjected to ASTM B117, 500 hour, 5% salt spray conditions, shows breakdown of less than 1/8" either side of a scribed line (equiv a lent to ASTM D1654 rating of “6”).

All exposed power wiring is be routed through liquid­tight, non-metallic conduit.
General Description
The Air Cooled Screw Chiller utilizes many com po nents which are the same or nearly the same as a stan dard reciprocating chiller of a similar size. This in cludes mod u lar frame rails, condenser, fans and evap o ra tor.
The chiller consists of 2 screw compressors in a cor re ­spond ing number of separate refrigerant circuits, a sin gle shell and tube DX counterfl ow evaporator, econ o miz ers, an air cooled condenser, and expansion valves.
Compressor
The semi-hermetic rotary twin-screw compressor is designed for industrial refrigeration applications and ensures high operational effi ciencies and reliable per- for mance. Capacity control is achieved through a sin gle slide valve. The compressor is a positive dis place ment type characterized by two helically grooved rotors which are manufactured from forged steel. The 60 Hz motor op­erates at 3550 RPM to direct drive the male rotor which in turn drives the female rotor on a light fi lm of oil.

FORM 201.19-NM1 (204)
Refrigerant gas is drawn into the void created by the unmeshing of the fi ve lobed male and seven lobed fe male rotor. Further meshing of the rotors closes the ro tor threads to the suction port and progressively com press es the gas in an axial direction to the discharge port. The gas is compressed in volume and increased in pressure before exiting at a designed volume at the dis charge end of the rotor casing. Since the intake and dis charge cy cles overlap, a resulting smooth fl ow of gas is maintained.
The rotors are housed in a cast iron compressor hous ing precision machined to provide optimal clearances for the rotors. Contact between the male and female rotor is pri ma ri ly rolling on a contact band on each of the rotor’s pitch circle. This results in virtually no rotor wear and in creased reliability, a trademark of the screw com pres sor.
The compressor incorporates a complete anti-friction bearing design for reduced power input and increased reliability. Four separated, cylindrical, roller bearings handle radial loads. Angular-contact ball bearings han dle axial loads. Together they maintain accurate rotor po si tion ing at all pressure ratios, thereby min i miz ing leak age and maintaining effi ciency. A springless check valve is installed in the compressor discharge housing to pre vent compressor rotor backspin due to system re frig er ant pressure gradients during shut down.
The compressor is lubricated by removing oil from the refrigerant using an external oil separator. The pres sur ized oil from the oil separator is then cooled in the condenser coils and piped back to the compressor for lubrication. The com pres sor design working pressure is 450 PSIG (31 bar). Each chill er receives a 300 PSIG (21 bar) low side and a 450 PSIG (31 bar) high side factory test. A 350 watt (115-1-60) cartridge heat er is located in the com pres sor. The heat er is tem per a ture activated to prevent re frig er ant condensation.
The following items are also included:
• An acoustically tuned, internal discharge muffl er to min i mize noise, while maintaining max i mum fl ow and performance.
• Discharge shutoff valve.
• A rain-tight terminal box.
• A suction gas screen and serviceable, 0.5 - 3.0 micron full fl ow oil fi lter within the compressor housing.
Evaporator
The system uses a high effi ciency Shell and Tube type Di rect Ex pan sion Evaporator. Each of the 2 re frig er ant circuits consists of 4 passes with the chilled liq uid cir cu lat ing back and forth across the tubes from one end to the other.
2
Motor cooling is provided by suction gas from the evap o ra tor flowing across the motor. Redundant over load pro tec tion is provided using both thermistor and cur rent over load protection.

FIG. 2 – SCREW COMPRESSOR
The design working pressure of the standard evaporator on the shell side is 150 PSIG (10 bar), and 350 PSIG (24 bar) for the tube (refrigerant side). The water baffl es are fab ri cat ed from galvanized steel to resist corrosion. Re mov able heads are provided for access to internally en hanced, seamless, copper tubes. Water vent and drain con nec tions are included.
The evaporator is equipped with a heater for protection to -20°F (-29°C) ambient and in su lat ed with 3/4" (19 mm) fl exible closed-cell foam.
The water nozzles are provided with grooves for me chan i cal couplings and should be insulated by the con trac tor after pipe installation.
Condenser
The fi n and tube condenser coils are manufactured from seamless, internally enhanced, high condensing co ef fi cient, corrosion resistant copper tubes arranged in

stag gered rows and mechanically expanded into cor ro sion resistant aluminum alloy fi ns with full height fi n col lars. They have a design working pressure of 450 PSIG (31 bar). Each coil is rested to 495 PSIG (34 bar).
Multiple fans move air through the coils. They are dy nam i cal ly and statically balanced, direct drive with cor ro sion re sis tant glass fi ber reinforced composite blades mold ed into low noise, full airfoil cross section, pro vid ing vertical air discharge from extended orifi ces for ef fi cien cy and low sound. Each fan is located in a sep a rate com part ment to prevent cross fl ow during fan cy cling. Guards of heavy gauge, PVC coated galvanized steel are pro vid ed.
The fan motors are high effi ciency, direct drive, 6-pole, 3-phase, Class- “F,” current overload protected, totally en closed (TEAO) type with double sealed, per ma nent ly lubricated ball bearings.
Economizer
Economizer is a refrigerant to refrigerant, compact plate­type heat exchanger to maximize chiller capacity and effi ciency by subcooling liquid refrigerant delivered to the cooler expansion valve. Constructed of corrosion resistant stainless steel plates formed to induce turbulent ow and enhance heat transfer, then oven brazed and pressure tested for reliability. Designed and constructed with ASME and TÜV certifi cation for 31 bar (450 psig). UL/CSA listed.
Oil Separator/System
The external oil separator, with no moving parts and de signed for minimum oil carry-over, is mounted in the dis charge line of the compressor. The high pressure dis charge gas is forced around a 90 degree bend. Oil is forced to the outside of the separator through cen trif u gal action and captured on wire mesh where it drains to the bottom of the oil separator and fl ows to the condenser for cooling before returning to the compressor.
assure re frig er ant compression (volumetric ef fi cien cy). The oil also provides cooling by transferring much of the heat of com pres sion from the gas to the oil keeping dis charge tem per a tures down and reducing the chance for oil breakdown. Oil injected into the rotor cage fl ows into the ro tors at a point about 1.2x suction. This assures that a required minimum differential of at least 30 PSID (2.1 bar) exists between discharge and 1.2x suc tion, to force oil into the rotor case. A minimum of 10 PSID (0.6 bar) is all that is re quired to assure pro tec tion of the compressor. Oil pressure safety is mon i tored as the dif fer ence between suction and the pres sure of the oil en ter ing the ro tor case.
Maximum working pressure of the oil separator is 450 PSIG (31 bar). Oil level should be above the midpoint of the “low er” oil sight glass when the compressor is run ning. Oil level should not be above the top of the “up per” sight glass.
Oil Cooling
Oil cooling is provided by routing oil from the oil sep a ­ra tor through several of the top rows of the con dens er coils and back to the compressor.
Capacity Control
The compressors will start at the minimum load po si tion and provide a capacity control range from 10% - 100% of the full unit load using a continuous function slide valve. The microprocessor modulates a voltage signal to a 3-way pres sure reg u lat ing capacity control valve which controls com pres sor capacity, in de pen dent of system pressures, and balances the com pres sor ca pac i ty with the cool ing load. Loading is ac com plished by varying pressure through the pressure regulating ca pac i ty control valve to move the slide valve against the spring pressure to promote stable smooth loading.
Automatic spring return of the slide valve to the min­ i mum load position will ensure compressor start ing at min i mum motor load.
The oil (YORK “L” oil – a POE oil used for all re frig ­er ant applications), which fl ows back into the com- pres sor through a replaceable 0.5 - 3.0 micron oil fi lter, is at high pressure. This high pres sure “oil injection” forces the oil into the com pres sor where it is fed to the bearings for lubrication. After lubricating the bearings, it is injected through orifi ces on a closed thread near the suction end of the rotors. The oil is automatically in ject ed because of the pressure difference between the discharge pres sure and the reduced pressure at the suc­ tion end of the rotors. This lubricates the rotors as well as provides an oil seal against leakage around the ro tors to

Power and Control Panel
All controls and motor starting equipment are factory wired and function tested. The panel enclosures are de signed to IP55 and are manufactured from powder paint ed galvanized steel.
The Power and Control Panel are divided into power sec tions for each compressor and associated fans, a con­ trol section and an electrical options section. The pow er and control sections have separate hinged, latched, and gasket sealed doors equipped with wind struts.

Each power compartment contains:
Compressor and fan starting contactors, fan motor ex ter nal overloads, control circuit serving compressor ca pac i ty control, compressor and fan contactor coils and compressor motor overloads. (Fig #1, page 12)
Current transformers in the 2ACE module provide compressor motor over load protection and sense each phase. This protects the compressor motors from dam age due to: low current input, high input current, un bal anced current, single phasing, phase reversal, and com pres sor locked rotor.
The control section contains:
ON/OFF switch, microcomputer keypad and display, mi cro pro ces sor board, I/O expansion board, relay boards and power supply board.
The options sections contain:
A control circuit transformer complete with service switch providing 115/1/60 Hz power to the unit con trol system.
Electrical options as described in “Accessories and Options.”
Microprocessor Controls
The microprocessor has the following functions and displays:
• A liquid crystal 40 character display with text pro­ vid ed on two lines and light emitting diode back­ light ing out door viewing.
Motor Current Protection
The microprocessor motor protection provides high cur rent protection to assure that the motor is not damaged due to voltage, excess refrigerant, or other problems that could cause excessive motor current. This is ac com plished by sending a current signal pro por tion al to motor current from the Motor Protector mod ule to the I/O Expansion board to be multiplexed and sent to the Microprocessor Board. If the motor cur rent exceeds the 115% FLA trip point after 3 seconds of op er a tion on either Wye-Delta or ACL starters, the mi cro will shut the system down and lock it out after one fault. A manual reset of the re spec tive system switch is re quired to clear the fault and restart the system. A thor ough check of the mo tor, wiring, and refrigerant system should be done be fore restarting a system that has fault ed on high motor current.
The micro also provides low motor current protection when it senses a motor current less than 10% FLA. The micro will shut the system down whenever low motor current is sensed and will lock out a system if three faults occur in 90 minutes. Low motor current pro tec tion is activated 4 seconds after start on both Wye-Delta and ACL starters to assure the motor starts, the sys tem doesn’t run with out refrigerant, the motor protector is not tripped, and the mechanical high pres sure cut-out is not tripped. Once the system is locked out on Low Motor Current, it must be manually reset with the sys tem switch. See also Motor Protection Module section below.

The micro senses low motor current whenever a HPCO or Motor Protector contact opens. This occurs because the MP and HPCO contacts are in series with the mo tor contactor. Whenever either of these devices are open, the contactor de-energizes and the motor shuts down. Since the micro is sending a run signal to the contactor, it senses the low motor current below 10% FLA and shuts the system down.

Motor Protection Modules (2ACE)
The mechanical motor protector is a Texas In stru ments 2ACE Three Phase Protection Module (Fig. 45, page
127), provides thermal and cur rent motor overload pro­ tec tion. This mod ule also pro tects against phase to phase cur rent im bal ance, over cur rent, under current, and phase ro ta tion. The mod ules, mount ed in the power pan els, uti liz es a 7 seg ment display which provides op er at ing sta tus and fault di ag nos tic in for ma tion. The 7 segment dis play will dis play ei ther a sta tion ary or a fl ash ing al- pha nu mer ic value which can be de cod ed by the op er a tor. A list of the codes follows:

Whenever a motor protector trips, the motor pro tec tor contacts wired in series with the motor contacts opens and the motor contactor de-energizes causing the mo tor to stop. The micro senses the low motor current and shuts the system down. The micro will try two more starts be fore locking the system out. The system locks out be cause the motor protector is a man u al re set de vice. Af ter the fi rst start, the modules’ contacts
will be open pre vent ing the motor contactors from en er giz ing. Power must be removed and re applied to re set the mod ule. Use CB3 in the Micro Panel to cycle power.
Current Overload
The 2ACE module design uses one integral current trans form er per phase to provide protection against rap id current over load conditions. The module re sponds to changes in current and must be cal i brat ed using DIP switches lo cat ed on the module. Integral trip curves al­ low for in-rush cur rents dur ing Wye-Delta, part wind, or ACL starts with out nuisance tripping.
To check the factory setting of the 2ACE module cur rent overload trip value. See Table 1 (pages 18 and 21).
For the location of the dip switches and determining the ON side of the switches, refer to Fig ure 45, page 127. As in di cat ed, to place a switch in the ON po si tion re quires push ing the switch to the left.
A switch must be pushed to the left to place the switch in the ON position. The numerical value for the combi­nation of "ON" switches equals the overload setting.
It is recommended that a YORK Ser­ vice Tech ni cian or the YORK fac to ry be con sult ed before chang ing these settings for any rea son, since dam­ age to the com pres sor could re sult. Chang es should nev er be made un­ less it is ver i fi ed that the set tings are in cor rect.
Anytime a dip switch change is made, pow er must be cycled off and on to the module to re pro gram the mod ule to the new value.

Thermal Overload
Three PTC (positive temperature co ef fi cient) ther mistors in the motor windings provides thermal pro tec tion. The sensor re sis tance stays rel a tive ly con stant at 1k
until
a tem per a ture of 266°F (130°C) is sensed. The sensor ex pe ri enc es a rapid rise in re sis tance be yond this tem­ per a ture. When ev er the re sis tance of one of the sen sors reach es 13k
Ω, +/− 3k, the 2ACE module trips, which
ul ti mate ly de-energizes the mo tor’s pi lot cir cuit. Re set is manual after the mo tor cools and the sen sor re sis tance drops to 3.25k
Ω, +/− 0.5kΩ.
Current Imbalance (Loaded & Unloaded)/ Loss of Phase
A 2 second delay at start-up allows for any imbalances resulting during normal starting conditions. After this ini tial delay, the 2ACE module compares the “Op er ­at ing Current” to the measured half line current. The “Op er at ing Current” is given by 0.65 X factory overload cur rent setting.
An unloaded compressor condition occurs when any measured half line current is less than the “Operating
Current.” A current imbalance exceeding an unloaded level of 25% will result in the motor pilot circuit being de-energized.
A loaded compressor condition occurs when any mea- sured half line current is great er than or equal to the “Operating Current.” A cur rent imbalance exceeding a loaded level of 17% will result in the motor pilot cir cuit being de-energized.
Imbalance is defi ned as (High Phase - Low Phase)/High Phase
Improper Phase Sequence
The 2ACE module calculates the phase sequence at start-up using the three cur rent transformers to de­ ter mine wheth er the three phase sequence on the load side of the main contactor is miswired. Upon de tec tion of a miswired motor load, the mod ule will de-energize the main contactor pi lot circuit within 50 millisecond re sponse time.

MOTOR STARTING

Two types of compressor motor starting are available: Across-the-Line and optional Wye-Delta Open Tran­ si tion Start er.
Across-the-Line starters will utilize one contactor and one start relay per compressor. The optional Wye-Delta start er utilizes 4 motor contactors, a transition delay re lay, a start relay, and a start-wye relay.
The Wye-Delta start allows inrush current to be limited to approximately 33% LRA for the fi rst 4 to 7 sec onds, with current increasing to normal running cur rent when the Delta connection is completed.
When the micro initiates a start signal at Relay Output Board #1 (SYS 1) Terminal 20 or Relay Output Board #2 (SYS 2) Ter mi nal 20 to run a com pres sor, the 1CR (SYS 1) or 2CR (SYS 2) relay is en er gized. The tran­ si tion of the 1CR (SYS 1) or 2CR (SYS 2) relay contacts en er giz es the 1S (SYS 1) or 2S (SYS 2) relay approx. 16ms later. The 1S/2S con tacts in turn en er gize the 1M (SYS 1) or 3M (SYS 2) mo tor con tacts 16ms later. This com pletes the “WYE” con nec tion of the motor start. At the same time, the normally closed 1S/2S auxiliary in ter lock con tact opens pre vent ing the 2M and 1 TRX (SYS 1) or 4M and 2 TRX (SYS 2) mo tor contactors from en er giz ing. 2 sets of aux il ia ry con tacts from 1M (SYS 1) or 3M (SYS 2) close, in ter lock ing the 1M (SYS
1) or 3M (SYS 2) contactors, keep ing them en er gized in par al lel with 1S (SYS 1) or 2S (SYS 2).
The “WYE” connection of the motor start is enabled for 4 to 7 seconds depending upon motor current as sensed by the microprocessor. The tran si tion to Delta takes 7 seconds if current is below 110% FLA. If mo­ tor current exceeds 110% FLA, the transition is made to Delta as long as the WYE has been enabled for at least 4 seconds.
After the “WYE” connection is enabled for 4 to 7 sec onds, the 1TR (SYS 1) or 2TR (SYS 2) transition delay relay is enabled by the microprocessor from Relay Out put Board #1 Terminal 8 (SYS 1) or Relay Out put Board #2 Terminal 6 (SYS 2). The 1TR (SYS 1) or 2TR (SYS 2) contacts open, de-energizing 1S (SYS 1) or 2S (SYS 2). 1M (SYS 1) or 3M (SYS 2) remain energizes through 2 sets of interlocking con tacts 1M (SYS 1) or 3M (SYS 2). Open ing of the 1TR (SYS 1) or 2TR (SYS
2) con tacts deenergizes 1S/2S and clos es the nor mal ly closed 1S (SYS 1) or 2S (SYS 2) con tacts, en er giz ing
1 TRX (SYS 1) or 2 TRX (SYS 2). 1TRX or 2TRX subsequently energizes motor contactor 2M (SYS 1) or 4M (SYS 2), com plet ing the “DELTA” con nec tion of the motor.
1 TR, 1 TRX, 2 TR, and 2 TRX are NOT “tim ing” re lays. These devices are sim ply pilot relays iden ti cal to 1CR and 2CR.

HANDLING AND STORAGE
FORM 201.19-NM1 (204)

DELIVERY AND STORAGE

To ensure consistent quality and maximum reliability, all units are tested and inspected before leaving the fac to ry. Standard units are shipped completely assembled and con tain ing refrigerant under pressure. Units are shipped with out export crating unless this has been specifi ed on the Sales Order.
Units with remote evaporators will have the chiller and remote evaporator charged with nitrogen.
If the unit is to be put into storage, prior to installation, the following precautions should be observed:
Unit must be “blocked” so that the base is not
per mit ted to sag or bow.
• Ensure that all openings, such as water con nec tions, are securely capped.
• Do not store where exposed to ambient air tem per a­ tures exceeding 110°F (43°C).
• The condensers should be covered to protect the fi ns from potential damage and corrosion, par tic u lar ly where building work is in progress.
• The unit should be stored in a location where there is minimal activity in order to limit the risk of ac­ ci den tal physical damage.

INSPECTION

Remove any transit packing and inspect the unit to en­ sure that all components have been delivered and that no damage has occurred during transit. If any dam age is evident, it should be noted on the carrier's freight bill and a claim entered in accordance with the in struc tions giv en on the advice note.
Major damage must be reported immediately to your lo cal YORK representative.

MOVING THE CHILLER

Prior to moving the unit, ensure that the installation site is suitable for installing the unit and is capable of sup port ing the weight of the unit and all associated ser vic es.
The units are designed to be lifted using ca bles. A spread er bar or frame 88" (2250 mm) wide should be used in order to prevent damage to the unit from the lifting chains (See Figures 3 and 4).
Units are provided with lifting eyes extending from the sides of the base frame which can be attached to di rect ly using shackles or safety hooks (See Figure 4).
The unit must only be lift ed by the base frame at the points provided. Nev er move the unit on roll ers, or lift the unit using a forklift truck.
3
• To prevent inadvertent operation of the pressure relief devices the unit must not be steam cleaned.
• It is recommended that the unit is periodically in­ spect ed during storage.
YORK INTERNATIONAL
Care should be taken to avoid damaging the con dens er cooling fi ns when moving the unit.

INSTALLATION

LOCATION REQUIREMENTS

To achieve optimum performance and trouble-free ser vice, it is essential that the proposed installation site meets with the location and space requirements for the model being installed. For dimensions, weight and space requirements, including service access, refer to the Technical Data Section.
It is important to ensure that the minimum service ac­ cess space is maintained for cleaning and main te nance purposes.

OUTDOOR INSTALLATIONS

The units can be installed at ground level, or on a suitable rooftop location. In both cases an adequate sup ply of air is required. Avoid locations where the sound out put and air discharge from the unit may be ob jec tion able.
The location should be selected for minimum sun ex­ po sure and away from boiler fl ues and other sources of airborne chemicals that could attack the condenser coils and steel parts of the unit.
If located in an area which is accessible to un au tho rized persons, steps must be taken to prevent access to the unit by means of a protective fence. This will help to prevent the possibility of vandalism, accidental dam age, or possible harm caused by unauthorized re mov al of pro tec tive guards or opening panels to expose ro tat ing or high voltage components.
For ground level locations, the unit must be installed on a suitable fl at and level concrete base that extends to fully support the two side channels of the unit base frame. A one-piece concrete slab, with footings ex­ tend ing be low the frost line is recommended. To avoid noise and vibration transmission the unit should not be se cured to the building foundation.
FORM 201.19-NM1 (204)
Any ductwork or attenuators fi tted to the unit must not have a total static pressure resistance, at full unit air fl ow, exceeding the capability of the fans installed in the unit.

INDOOR INSTALLATIONS

The unit can be installed in an enclosed plant room pro vid ing the fl oor is level and of suitable strength to sup port the full operating weight of the unit. It is es sen tial that there is adequate clearance for airfl ow to the unit. The discharge air from the top of the unit must be duct ed away to prevent recirculation of air within the plant room. If common ducts are used for fans, non-return damp ers must be fi tted to the outlet from each fan.
The discharge ducting must be properly sized with a total static pressure loss, together with any intake stat ic pressure loss, less than the available static pressure ca pa bil i ty for the type of fan fi tted.
The discharge air duct usually rejects outside the build­ ing through a louver. The outlet must be positioned to pre vent the air being drawn directly back into the air in take for the condenser coils, as such recirculation will affect unit performance.

LOCATION CLEARANCES

Adequate clearances around the unit(s) are required for the unrestricted airfl ow for the air-cooled con dens er coils and to prevent recirculation of warm discharge air back onto the coils. If clearances given are not main tained, airfl ow restriction or recirculation will cause a loss of unit performance, an increase in power con sump tion and may cause the unit to malfunction. Con sid er ation should also be given to the possibility of down drafts, caused by ad ja cent buildings, which may cause recirculation or un even unit airfl ow.
4
On rooftop locations, choose a place with adequate struc tur al strength to safely support the entire op er at ing weight of the unit and service personnel. The unit can be mount ed on a concrete slab, similar to ground fl oor locations, or on steel channels of suitable strength. The channels should be spaced at the same centres as the vibration mounting holes in the unit base frame and must be at least 4-3/4" (120 mm) wide at the con tact points. This will allow vibration isolators to be fi tted if required.
YORK INTERNATIONAL
For locations where signifi cant cross winds are ex- pect ed, such as exposed roof tops, an enclosure of sol id or lou ver type is recommended to prevent wind tur bu lence in ter fer ing with the unit airfl ow.
When units are installed in an enclosure, the en clo sure height should not exceed the height of the unit on more than one side. If the enclosure is of louvered con struc ­tion the same requirement of static pres sure loss ap plies as for ducts and at ten u a tors stated above.
29
Page 30
Installation
FORM 201.19-NM1 (204)
Where accumulation of snow is likely, ad di tion al height must be provided under the unit to ensure normal air fl ow to the unit.
The clearance dimensions given are nec es sary to main tain good airfl ow and en sure cor rect unit op er a tion. It is also nec es sary to con sid er access re quire ments for safe op er a tion and maintenance of the unit and power and control pan els. Lo cal health and safe ty reg u la tions, or prac ti cal con­ sid er ations for ser vice re place ment of large com po nents, may require larg er clear anc es than those given in the Tech ni cal Data Section of this manual, (page 90).

COMPRESSOR FEET BOLT REMOVAL

After the chiller is placed in the fi nal location, remove the four bolts, 1 , attaching the compressor feet to the frame rails. These bolts are only used for shipping purposes. The bolts are screwed into the compressor feet from the bottom side of the frame rail. Refer to Figure 5.
After the four shipping bolts are removed from the compressor feet, the compressor will be held in place by the four corner brackets, 2.
This assembly reduces compressor noise by isolating the compressor from the base rails.
DO NOT remove the four 3/8" bolts, 3, mounting the corner brackets, 2, to the frame rails.

VIBRATION ISOLATORS

Optional sets of vibration isolators can be supplied loose with each unit.
Using the Isolator tables, refer to the Technical Data Section, identify each mount and its cor rect lo ca tion on the unit.
Installation
Place each mount in its correct position and lower the unit carefully onto the mounts ensuring the mount en­ gag es in the mounting holes in the unit base frame.
On adjustable mounts, transfer the unit weight evenly to the springs by turn ing the mount adjusting nuts (lo cat ed just be low the top plate of the mount) counter-clock wise to raise and clock wise to low er. This should be done two turns at a time until the top plates of all mounts are between 1/4" and 1/2" (6 and 12 mm) clear of top of their hous ing and the unit base is level.
A more detailed installation in struc tion is pro vid ed in the Installation Instruc­tions for VMC Series AWR/AWMR and CP Restrained Mountings Section of this manual, (page 107).

SHIPPING BRACES

The chiller’s modular design does not require shipping braces.

PIPEWORK CONNECTION

General Requirements
The following piping recommendations are intended to ensure satisfactory operation of the unit(s). Failure to follow these rec om men da tions could cause damage to the unit, or loss of per for mance, and may in val i date the warranty.
The maximum fl ow rate and pressure drop for the evaporator must not be ex ceed ed at any time. Re fer to the Tech ni cal Data Sec tion for de tails.
The liquid must enter the evaporator at the in let con nec tion. The inlet con­ nec tion for the evaporator is at the far end of the unit when viewed from the pow er and con trol pan els.
Water inlet is always nearest the suc­tion gas outlet on the DX evaporators. (chiller barrel)
A fl ow switch must be installed in the customer pipework at the outlet of the evaporator and wired back to the control panel using shielded ca ble. There
should be a straight run of piping of at least 5 pipe di­ am e ters on either side. The fl ow switch should be wired to Ter mi nals 13 and 14 (see Figs. 13 and 14, pages 40 and 41). A fl ow switch is re quired pre vent dam age to the evaporator caused by the unit op er at ing with out ad e quate liquid fl ow.
The fl ow switch used must have gold plated contacts for low voltage/current operation. Paddle type fl ow switch es suitable for 150 PSIG (10 bar) (optional 300 PSIG) working pres sure and hav ing a 1" N.P.T. con­nection can be obtained from YORK as an ac ces so ry for the unit. Al ter na tive ly a dif fer en tial pres sure switch sited across an orifi ce plate may be used, pref er a bly of the high/low limit type.
The chilled liquid pump(s) installed in the pipework system(s) should discharge directly into the unit evapora­tor section of the system. The pump(s) may be controlled external to the unit - but an override must be wired to the control panel so that the unit can start the pump in the event that the liquid temperature falls below the min i mum setting. For details refer to “Electrical Con nec tion.”

FORM 201.19-NM1 (204)
Pipework and fi ttings must be separately supported to prevent any loading on the evaporator. Flexible con­ nec tions are recommended which will also minimize transmission of vibrations to the building. Flexible
connections must be used if the unit is mounted on anti-vibration mounts as some movement of the unit can be ex pect ed in normal operation.
Pipework and fi ttings immediately next to the evapora- tor should be readily de-mountable to enable cleaning be fore operation, and to facilitate visual inspection of the exchanger nozzles.
The evaporator must be protected by a strainer, pref­ er a bly of 30 mesh, fi tted as close as possible to the liq uid inlet connection, and provided with a means of local isolation.
The evaporator must not be exposed to fl ushing veloci- ties or debris released during fl ushing. It is recommended that a suitably sized by-pass and valve arrangement is in stalled to allow fl ushing of the pipework system. The by-pass can be used during maintenance to isolate the heat exchanger without disrupting fl ow to other units.
Thermometer and pressure gauge connections should be provided on the inlet and outlet connections of each evaporator.
Drain and air vent connections should be provided at all low and high points in the pipework to permit drain age of the system and to vent any air in the pipes.
Any debris left in the water pipework be tween the strain er and evaporator could cause se ri ous damage to the tubes in the evaporator and must be avoided. The in stall er/user must also en sure that the quality of the wa ter in cir cu la tion is ad e quate, with out any dis solved gas es which can cause ox i da tion of steel parts within the evaporator.

WATER TREATMENT

The unit performance given in the Design Guide is based on a fouling factor of 0.00025 ft °C/kW). Dirt, scale, grease and cer tain types of water treat ment will ad verse ly affect the heat ex chang er sur­ fac es and there fore unit per for mance. Foreign mat ter in the water system(s) can increase the heat ex chang er pres sure drop, reducing the fl ow rate and caus ing po- ten tial damage to the heat exchanger tubes.
Aerated, brackish or salt water is not recommended for use in the water system(s). YORK recommends that a wa ter treatment specialist is consulted to determine the proposed water composition will not affect the evap o ­ra tor materials of carbon steel and copper. The pH val ue of the water fl owing through the evaporator must be kept be tween 7 and 8.5.
2
hr°F/Btu (0.044m2/hr
Liquid systems at risk of freezing, due to low ambient temperatures, should be protected using insulation and heater tape and/or a suitable glycol solution. The liquid pump(s) must also be used to ensure liquid is cir cu lat ed when the ambient temperature approaches freez ing point. Insulation should also be installed around the evaporator noz zles. Heater tape of 21 watts per meter un der the insulation is recommended, supplied in de ­pen dent ly and controlled by an ambient temperature ther mo stat set to switch on at 37°F (21°C) above the freez ing tem per a ture of the liquid.
The liquid circulation pump must be controlled by the unit. This will ensure that when the liquid temperature falls within 3° or 5°F (2° or 3°C) of freez ing, the pump will start.
The evaporator is protected by heater mats un der the in­ su la tion which are supplied from the unit con trol system pow er supply. Dur ing risk of freezing the control sys tem should be powered to provide the freeze pro tec tion func­ tion un less the liq uid systems have been drained.

PIPEWORK ARRANGEMENT

Figure #6 shows the suggested pipework arrangement for single unit in stal la tions. For mul ti ple unit installa­tions, each unit should be piped as shown.

CONNECTION TYPES & SIZES

For connection sizes relevant to individual models re fer to the Technical Data Section.

EVAPORATOR CONNECTIONS

Standard chilled liquid connections on all evaporators are of the Victaulic Groove type.
LD03521
FIG. 7 – VICTAULIC GROOVE
Optional Flanges
One of two types of fl anges may be fi tted depending on the customer or local Pressure Vessel Code re quire ments. These are Victaulic-Adapter fl anges, normally supplied loose, or weld fl anges which may be supplied loose or ready fi tted. Victaulic-Adapter and weld fl ange dimen- sions are to ISO 7005 - NP10.
It is recommended that a piece of pipe is fi tted to each valve and directed so that if the valve is activated, the release of high pressure gas and liquid cannot be a dan ger or cause injury. For indoor installations pres sure re lief valves should be piped to the exterior of the build ing.
The size of any pipework attached to a relief valve must be of suffi cient diameter so as not to cause resistance to the operation of the valve. Unless otherwise spec i fi ed by local regulations, internal diameter de pends on the length of pipe required and is given by the fol low ing formula:
D5 = 1.447 x L
Where: D = minimum pipe internal diameter in cm L = length of pipe in meters
If relief pipework is common to more than one valve its cross sectional area must be at least the total re quired by each valve. Valve types should not be mixed on a common pipe. Precautions should be taken to ensure that the outlet of relief valves/vent pipe remain clear of ob struc tions at all times.

DUCTWORK CONNECTION

General Requirements
The following ductwork rec om men da tions are in tend ed to ensure sat is fac to ry op er a tion of the unit. Failure to follow these rec om men da tions could cause damage to the unit, or loss of per for mance, and may invalidate the warranty.
LD03523
Weld Flange Victaulic Adapter
FIG. 8 – FLANGE ATTACHMENTS

REFRIGERANT RELIEF VALVE PIPING

Evaporators and oil separators are each protected against internal refrigerant overpressure by refrigerant relief valves. For evaporators, a pressure relief valve is mounted on each of the main refrigerant lines connecting the evaporator to the compressors.
YORK INTERNATIONAL
When ducting is to be fi tted to the fan discharge it is recommended that the duct should be the same cross sec­tional area as the fan outlet and straight for at least three feet (1 meter) to obtain static regain from the fan. Ductwork should be suspended with fl exible hangers to prevent noise and vibration being transmitted to the struc ture. A fl exible joint is also recommended be tween the duct attached to the fan and the next section for the same reason. Flexible connectors should not be al lowed to concertina.
The unit is not designed to take structural loading. No signifi cant amount of weight should be allowed to rest on the fan outlet fl ange, deck assemblies or condenser coil module. No more than 3 feet (1 meter) of light con struc tion ductwork should be supported by the unit. Where cross winds may occur, any ductwork must be sup port ed to prevent side loading on the unit.
33

Page 34
Installation
FORM 201.19-NM1 (204)
If the ducts from two or more fans are to be combined into a common duct, back-fl ow dampers should be fi t- ted in the individual fan ducts. This will prevent re cir ­cu la tion of air when only one of the fans is running.
Units are supplied with outlet guards for safety and to prevent damage to the fan blades. If these guards are re­moved to fi t ductwork, adequate alternative pre cau tions must be taken to ensure persons cannot be harmed or put at risk from rotating fan blades.

ELECTRICAL CONNECTION

The following connection rec om men da tions are in­ tend ed to ensure safe and sat is fac to ry operation of the unit. Failure to follow these recommendations could cause harm to persons, or damage to the unit, and may in val i date the warranty.
No additional controls (re lays, etc.) should be mount ed in the control pan el. Power and con trol wiring not con nect ed to the con trol pan el should not be run through the control pan el. If these pre cau tions are not fol lowed it could lead to a risk of elec tro cu tion. In ad di tion, elec tri cal noise could cause mal func tions or dam age the unit and its con trols.
All sources of supply to the unit must be taken via a common point of iso­ la tion (not sup plied by YORK).

STANDARD UNITS WITH MULTI POINT POWER SUPPLY WIRING

Standard units require two 3-phase sep a rate ly fused 3­wire supplies plus a ground per re frig er ant system. One supply to be connected to each of the power panels.
Connect each of the main 3-phase supplies to the cir­ cuit breakers, non-fused disconnect switches or ter mi nal boards located in the power panels using lug sizes de­ tailed in the Technical Data Section.
Connect the ground wires to the main protective ground terminals in each power panel.
Units with Single-Point Power Supply Wiring
Units require only one 3-phase supply plus ground.
Connect the 3-phase supplies to the terminal block or non-fused disconnect switch/circuit breaker located in the options pan el using lug sizes detailed in the Techni­cal Data Section.
After connection do not switch on main pow er to the unit. Some in ter nal com po nents are live when main power is switched on and this must only be done by Au tho rized persons.

POWER WIRING

All electrical wiring should be carried out in ac cor dance with local regulations. Route properly sized cables to cable entries on both sides of the unit.
In accordance with U.L. Standard it is the re spon si bil i ty of the user to install overcurrent pro tec tion devices be tween the supply con duc tors and the power supply ter mi nals on the unit.
To ensure that no eddy currents are set up in the power panel, the cables forming each 3-phase power supply must enter via the same cable entry.
Connect a ground wire to the main protective ground terminal.

115VAC CONTROL SUPPLY TRANSFORMER

A 3-wire high voltage to 115VAC supply transformer is standard in the chiller. This transformer steps down the high voltage supply to 115VAC to be used by the Micro Panel, Pow er Pan el com po nents, so le noids, heat­ers, etc.
The high voltage for the transformer pri ma ry is taken from the chiller input to one of the sys tems. Fusing is provided for the trans form er.
It is important to check that the cor­ rect primary tap ping has been used and that it con forms to the site high volt age sup ply.
34
YORK INTERNATIONAL
Page 35
FORM 201.19-NM1 (204)
Removing high voltage power to the chill er will re move the 115VAC sup­ ply voltage to the mi cro pro ces sor cir­ cuit ry and the evap o ra tor heater. In cold weath er, this could cause serious dam age to the chill er due to evap o ra tor freeze-up. Do not re move power un less alternate means are taken to as sure op er a tion of the evap o ra tor heat er.
Remote Emergency Stop Device
If required, a remote emergency stop de vice can be wired into the unit. The device should be wired into ter mi nals 31 and 32 (Figs. 13 and 14, pages 40 and 41.) in the mi cro pro ces sor con trol pan el.

CONTROL PANEL WIRING

All wiring to the control panel terminal block terminals 13-19 is nom i nal 30VDC and must be run in shielded cable, with the shield grounded at the panel end only. Run shielded ca ble sep a rate ly from mains cables to avoid electrical noise pick-up. Use the control panel cable entry to avoid the pow er cables.
Run Contact
Terminals 29 and 30 (Figs. 13 and 14, pages 40 and 41) close to in di cate that a sys tem is running.
Alarm Contacts
Each system has a voltage-free change over contact which will operate to signal an alarm condition when­ ev er a system locks out, or there is a power failure. To obtain system alarm signal, connect the alarm circuit to volt free terminals 23 and 24 (Figs. 13 and 14, pages 40 and 41) for No. 1 Sys tem and to ter mi nals 27 and 28 (Figs. 13 and 14) for No. 2 Sys tem.

SYSTEM INPUTS

Flow Switch
A chilled water fl ow switch, (either by YORK or others) MUST be installed in the leaving water piping of the evaporator. There should be a straight horizontal run of at least 5 diameters on each side of the switch. Adjust the fl ow switch paddle to the minimum fl ow allowed through the evaporator. (See manufacturer's instructions furnished with the switch.) The switch is to be wired to terminals 13 - 14 of CTB1 located in the control panel, as shown on the unit wiring diagram.
The voltage free contacts supplied must be suitable for 30VDC (gold contacts recommended). If the voltage free con tacts are from a relay or contactor, the coil of the device must be suppressed using a standard R/C sup pres sor. The above precautions must be taken to avoid electrical noise which could cause a malfunction or dam age to the unit and its controls.
The length of cable to these terminals must not exceed 25 ft. (7.5 m) unless an isolator is fi t ted.

VOLTS FREE CONTACTS

Chilled Liquid Pump Starter
Terminals 25 and 26 (Figs. 13 and 14, pages 40 and 41) close to start the chilled liquid pump. This contact can be used as a master start/stop for the pump in con junc tion with the daily start/stop schedule. See Section 8.1.15.
Remote Run / Stop
Connect remote switch(es) in series with the fl ow switch to provide remote run/stop control if required.
Remote Print
Closure of suitable contacts connected to terminals 13 and 18 (Figs. 13 and 14, pages 40 and 41) will cause a hard copy printout of Operating Data/Fault History to be made if an optional printer is con nect ed to the RS 232 port.
Remote Setpoint Offset – Temperature
Timed closure of suitable contacts connected to ter mi nals 13 and 17 (PWM contacts) will provide re mote off set function of the chilled liquid set point if re quired. See Figs. 13 and 14, pages 40 and 41 for contact lo ca tion.
Remote Setpoint Offset – Current
Timed contact closure of a suitable contact connected to terminals 13 and 16 (PWM contacts) will provide re mote offset of EMS% CURRENT LOAD LIMIT. See Figs. 13 and 14, pages 40 and 41 for contact lo ca tion.

COMMISSIONING

PREPARATION

Commissioning of this unit should only be car ried out by YORK Au tho ­rized per son nel.
The Millennium Microcomputer Con trol Sys tem Op er at ing In struc tions must be read in con junc tion with this sec tion.

PREPARATION – POWER OFF

The following checks should be made with the cus tom er supply/supplies to the unit switched OFF.
Inspection
Inspect unit for installation dam age. If damage is found take ac tion and/or repair as appropriate.
Refrigerant Charge
Units are normally shipped as stan dard with a full re frig er ant operating charge. Check that refrigerant pres sure is present in both systems and that no leaks are ap par ent. If no pressure is present a leak test must be un der tak en. The leak(s) should be located and re paired. Re paired sys tems and units supplied with a ni tro gen hold ing charge must be evacuated with a suit able vac­uum pump/re cov ery unit as appropriate to be low 100 microns.
Do not liquid charge with static water in the evaporator. Care must also be taken to liquid charge slowly to avoid ex ces sive thermal stress at the charging point. Once the vacuum is broken, charge into the condenser coils with the full operating charge as given in the Technical Data Section.
or cop per line, but do not tighten the fl are nut. Using clean oil of the correct type (“L” oil), pump oil until all air has been purged from the hose then tight en the nut. Stroke the oil pump to add oil to the oil sys tem. The oil level should be between the mid dle of the low er and mid dle of the up per sight glasses of the oil sep a ra tor. Ap prox i mate ly 5 gal lons is present in the entire chill er system, with 1-2 gal lons in the oil separator.
Fans
Check that all fans are free to rotate and are not dam­ aged. Ensure blades are at the same height when ro tat ed. Ensure fan guard is securely fi xed.
Isolation/Protection
Verify that all sources of elec tri cal supply to the unit are taken from a single point of iso la tion. Check that the maximum recommended fuse siz es given in the Tech ni cal Data Section have not been exceeded.
Control Panel
Check the panel to see that it is free of foreign ma te ri als (wire, metal chips, etc.) and clean out if required.
Power Connections
Check to assure the customer power ca bles are connected cor rect ly. Ensure that con nec tions of power cables within the panels to the circuit breakers, terminal blocks or switch disconnectors are tight.
Grounding
Verify that the unit’s protective terminal(s) are prop er ly connected to a suitable grounding point. Ensure that all unit internal ground connections are tight.
Overloads
Ensure that the fan overloads settings are correct for the type of fan fi tted.
Valves
Open each compressor suction, economizer, and dis­ charge valve ful ly (counter-clockwise) then close one turn of the stem to ensure operating pressure is fed to the pres sure trans duc ers. Open the liquid line service valve ful ly and en sure the oil re turn line ball valve is open in each system.
Compressor Oil
To add oil to a circuit - connect a YORK hand oil pump (Part No. 470-10654-000) to the 1/4" oil charging valve on the oil separator piping with a length of clean hose
42
Supply Voltage
Verify that the site voltage supply cor re sponds to the unit requirement and is within the lim its given in the Tech ni cal Data Section.
Control Transformer
The 3-wire control transformer is mounted external to the panel. It is important to check that the correct pri ma ry tapping has been used:
With the supply voltage to the unit turned off, remove the lid to the transformer box.
YORK INTERNATIONAL
Page 43
FORM 201.19-NM1 (204)
Check that the tapping used conforms to the site sup ply voltage. After the tapping is verifi ed, replace the lid.
Switch Settings
Ensure that the unit ON/OFF switch on the display door and the micro board system switch es S2 through S5 are set to “0” (OFF). Set the red han dled emergency stop de vice on the options panel to “1” (ON). For units fi tted with door interlocked circuit breakers the power panel doors must be closed and the devices set to “1” (ON). The customer’s power dis con nec tion devices can now be set to ON.
The machine is now live!
The unit is fi tted with an under voltage circuit in each pan el and it may take be tween 5 to 10 seconds for its con tacts to close and energize the unit’s electronics, in clud ing the dis play on the main panel.
Compressor Heaters
Verify the compressor heaters are en er gized. If the ambient temperature is above 96°F (36°C) the com pres sor heaters must be on for at least 8 hours before start-up to ensure all refrigerant liquid is driven out of the compressor. If the ambient tem per a ture is be low 86°F (30°C) then allow 24 hours.
Water System
Verify that the chilled liquid system has been installed correctly, and has been commissioned with the correct direction of water fl ow through the evaporator. The inlet should be at the refrigerant pipework connection end of the evaporator. Purge air from the top of the evaporator using the plugged air vent mounted on the top of the evaporator body. Flow rates and pressure drops must be within the limits given in the Technical Data Section. Op er a tion outside of these lim its is un de sir able and could cause damage.
Flow Switch
Verify a chilled water fl ow switch is cor rect ly fi tted in the customer’s pipework on the evaporator outlet, and wired into the control panel correctly using shielded
cable. There should be a straight run of at least 5 pipe di am e ters on either side of the fl ow switch. The fl ow switch should be connected to terminals 13 and 14 in the mi cro panel (Figs. 13 and 14, pages 40 and 41).
Temperature Sensor(s)
Ensure the leaving liquid tem per a ture sensor is coated with heat conductive com pound (part no. 013-00890-

Commissioning
FORM 201.19-NM1 (204)

FIRST TIME START-UP

During the commissioning period there should be suf fi cient heat load to run the unit under sta ble full load op er a tion to enable the unit con trols, and sys tem op er a tion to be set up cor­ rect ly and a com mis sion ing log tak en. Be sure that the Micro Panel is prop­ er ly pro grammed (page 166) and the Sys tem Start-up Check list (page 117) is com plet ed.
Interlocks
Verify that liquid is fl owing through the evaporator and that heat load is present. Ensure that any remote run in­ ter locks are in the run position and that the run schedule requires the unit to run or is overridden.
System Switches
Place the ‘Sys 1’ switch on the mi cro pro ces sor board to the ‘ON’ position – (Fig. 46, page 130).
Start-up
Remove the locking device from the unit Auto/OFF switch which prevents unauthorized starting of the unit before commissioning. Press the ‘Status’ key, then turn the unit switch to the “1” position to start the unit (there may be a few seconds delay before the fi rst com pres sor starts be cause of the anti-recycle timer). Be ready when each com pres sor starts, to switch the unit OFF im me ­di ate ly if any unusual noises or other adverse con di tions de vel op. Use the appropriate emergency stop de vice if necessary.
Oil Pressure
When a compressor starts, press the rel e vant ‘System Pressures’ key and verify that oil dif fer en tial pressure develops immediately (Discharge Pressure minus Oil Pressure). If oil pressure does not develop, the automatic controls will shut down the compressor. Un der no cir­ cum stanc es should a restart attempt be made on a com­ pres sor which does not develop oil pres sure im me di ate ly. Switch the unit switch to the ‘0’ po si tion (OFF).
Refrigerant Flow
When a compressor starts, a fl ow of liquid refrigerant will be seen in the liquid line sight glass. After several min utes operation and providing a full charge of re frig ­er ant is in the system, the bubbles will disappear and be re placed by a solid column of liquid.
Fan Rotation
As discharge pressure rises, the con dens er fans op er ate in stages to control the pressure. Verify that the fan op­eration is correct for the type of unit.
Suction Superheat
Check suction superheat at steady full compressor load only. Measure suction tem per a ture on the copper line about 6" (150 mm) before the compressor suc tion ser­ vice valve. Measure suction pres sure at the com pres sor service valve. Superheat should be 10°F to 12°F (5.6°C to 6.7°C).
Expansion Valve
The electronic expansion valves are factory set and should not need adjustment.
Economizer Superheat (Not all models are equipped with economizers)
Check economizer su per heat at steady full com pres sor load only, under conditions when the econ o miz er sole­noid is energized. (See Section 1.22, page 134) Measure gas tem per a ture on the econ o miz er outlet pipe next to the ex pan sion valve bulb. Mea sure gas pressure at the back seat port of the economizer ser vice valve. Su per heat as measured should be 10°F to 12°F (5.6°C to 6.7°C).
Subcooling
Check liquid subcooling at steady full com pres sor load only. It is important that all fans are run ning for the sys tem. Measure liquid line temperature on the copper line beside the main liquid line service valve. Measure liq uid pressure at the liquid line service valve. Subcooling should be 12°F to 15°F (6.7°C to 8.3°C). No bubbles should show in the sight glass. If subcooling is out of range add or re move re frig er ant as required. Do not over charge the unit. The liq uid fl ow to the main evaporator TXV is subcooled fur ther by the econ o miz er, increasing subcooling to be tween 22°F and 28°F (12°C and 15°C) at ambients above 90ºF.
General Operation
After completion of the above checks for System 1, stop the unit, switch OFF the ‘SYS 1’ switch on the main panel microprocessor board and repeat the pro cess for each subsequent system. When all run cor rect ly, stop the unit, switch all applicable switch es to the ‘ON’ po si tion and restart the unit.

OPERATION

GENERAL DESCRIPTION

The units are designed to work independently, or in con junc tion with other equipment via a YORK ISN build ing management system or other automated con­trol sys tem. When operating, the unit controls monitor the chilled liquid system temperature at the unit and take the ap pro pri ate action to maintain this temperature with in de sired limits. This action will involve running one or more compressors at a suitable load step to match the cool ing effect of the refrigerating systems to the heat load on the liquid system. The heat removed from the chilled liquid is then rejected from the air cooled con dens er coils.
The following sections give an overview of the op er a tion of the unit. For detailed information, reference should be made to the Chiller Control Panel Pro gram ming and Data Access Op er at ing In struc tions for the unit (pages 122 - 192).

START-UP

Check the main power supplies to the unit are ‘ON’, all refrigerant service valves are open (counter-clockwise one turn short of fully open) and chilled liquid fl ow has been es tab lished (unless the unit chilled liquid pump start con trol is being used, in which case just ensure the pump supply is on). Ensure only the correct system switches (SYS 1-2) on the microprocessor cir cuit board are in the ‘ON’ position.
Press the ‘STATUS’ key on the keypad and then switch the unit ON/OFF switch below the keypad to the ON position.
The controller will perform a pre-check to ensure that the daily/holiday schedule and any remote interlocks will allow the unit to run, all safety cut-outs are sat is fi ed and that cooling load is required (i.e. that the chilled liquid temperature is outside the set limits). Any prob lems found by the pre-check will be displayed if present. If no prob lems are present and cooling duty is required the lead compressor will start.
The display will show the anti-coincidence timer sta tus for the lag compressor, followed by ‘NO COOL LOAD’ until it is called to operate by the control sys tem.

NORMAL RUNNING AND CYCLING

Once the unit has been started, all operations are fully automatic. After an initial period at minimum capacity on the lead compressor, the control system will adjust the unit load depending on the chilled liquid tem per a ture and rate of temperature change. If high heat load is pres­ent, the controller will increase the capacity of the lead compressor and/or start-up the other compressor.
If very little heat load is present, the lead compressor will continue at minimum capacity or may simply stop again to avoid overcooling the liquid. If the latter is the case, one compressor will restart automatically should the liquid temperature rise again.
Once a compressor is running, discharge pressure ris es as refrigerant is pumped into the air cooled con dens er coils. This pressure is controlled by stages of fans to ensure maximum unit effi ciency while main tain ing suf- fi cient pressure for correct operation of the con dens ers and expansion valves.
When a compressor is running, the controller monitors oil pressure, motor current, and various other system parameters such as discharge pressure, chilled liquid temperature, etc. Should any problems occur, the con trol system will immediately take appropriate action and display the nature of the fault (Section 8).

SHUTDOWN

The unit can be stopped at any time by switching the UNIT ON/OFF switch just below the keypad to the OFF po si tion. The compressor heat er will en er gize to prevent refrigerant condensing in the com pres sor rotors. If ambient tem per a tures are low, the evaporator heater mats will also en er gize to pre vent the possibility of liq­uid freezing in the ves sels. The mains pow er to the unit should not nor mal ly be switched OFF, even when the unit is not re quired to run.
The system switches (S2-S5) on the microboard can be used to cycle a system OFF. An automatic pumpdown will occur using the system switches.
If mains power must be switched OFF, (for extended main te nance or a shutdown period), the compressor suc­tion, discharge and motor cooling service stop valves should be closed (clockwise) and if there is a pos si bil i ty of liq uid freezing due to low ambient temperatures, the evaporators should be drained. Valves should be opened and power must be switched on for at least 8 Hours (36 Hours if ambient temperature is over 86°F [30°C]) be fore the unit is restarted.

GLYCOL CORRECTION FACTORS

The evaporator is designed in accordance with ARI-590­92 which allows for an increase in pres sure drop of up to 15% above the design value given above. Debris in the water may also cause additional pressure drop.
When using glycol solutions, pressure drops are high er than with water (see correction factors to be applied when using glycol solutions).
A = Correction Factor B = Mean Temperature through Evaporator (°C) C = Concentration W/W (%)
Excessive fl ow, above the max GPM, will damage the evaporator.
GLYCOL CORRECTION EXAMPLE: (With YCAS0140)
RWT = 36°F LWT = 28°F
Average Water Temperature = 32°F (= 0°C)
For 30% Propylene Glycol: From Graph, Find Correction Factor =

NOTES:
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 pro vid ed, add the following to the system #1 MCA values in the YCAS Tables: -17, add 15 amps; -28, add 12 amps; -40, add 7 amps; -46, add 6 amps; -58, add 5 amps.
2. 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.
3. Minimum recommended fuse size is based on 150% of the largest motor RLA plus 100% of the remaining RLAs. Minimum fuse rating = (1.5 x largest compressor RLA) + other compressor RLAs + (# fans x each fan motor FLA).
4. 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. Maximum fuse rating = (2.25 x largest compressor RLA) + other compressor RLAs + (# fans x each fan motor FLA).
5. Minimum recommended circuit breaker is 150% maximum plus 100% of rated load amps included in the circuit. Minimum circuit breaker rating = (1.5 x largest compressor RLA) + other compressor RLAs + (# fans x each fan motor FLA).
6. Maximum circuit breaker is based on 225% maximum plus 100% of the rated load amps for all loads included in the circuit, per circuit, per U.L. 1995 Fig. 36.2. Maximum circuit breaker rating = (2.25 x largest compressor RLA) + other com pres sor RLAs + ( # fans x each fan motor FLA).
7. The Incoming Wire Range is the minimum and maximum wire size that can be accommodated by unit wiring lugs. The (1), (2), or (3) indicate the number of termination points or lugs which are available per phase. 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 conductors only. Field wiring must also comply with local codes.
8. A ground lug is provided for each compressor system to accommodate fi eld 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.
9. The fi eld supplied disconnect is a “Disconnecting Means” as defi ned 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.
10.Two-Compressor machines with single-point power connection, and equipped with Star (Wye)-Delta Compressor motor start must also include factory-provided individual system circuit breakers in each motor control center. All 3 & 4 Compressor machines equipped with Star-Delta com pres sor motor start must also include factory-provided individual system circuit breakers in each motor control center.
11.Consult factory for Electrical Data on units equipped with “High Static Fan” option. High Static Fans are 3.8 kW each.
12.FLA for “Low Noise Fan” motors: 200V = 8.0A, 230V = 7.8A, 380V = 4.4A, 460V = 3.6A, 575V = 2.9A.
