1Rotating Parts Fan guards must be fitted at all times and not removed unless the power supply has been isolated. If ductwork is to be fitted, 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 fins on the air-cooled condenser coils have sharp metal edges. Reasonable care should be taken when working in contact with the coils to avoid the risk of minor abrasions and lacerations. The use of gloves is recommended.
Frame rails, brakes, and other components may also have sharp edges. Reasonable care should be taken when working in contact with any components to avoid risk of minor abrasions and lacerations.
Refrigerants and Oils Refrigerants and oils used in the unit are generally non-toxic, non-flammable and non-corrosive, and pose no special safety hazards. Use of gloves and safety glasses is, however, recommended when working on the unit.
The build up of refrigerant vapor, from a leak for ex-ample, does pose a risk of asphyxiation in confined or enclosed spaces and attention should be given to good ventilation.
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 pressure relief device(s). Detergents and solvents, which may cause corrosion, should also be avoided.
Emergency Shutdown In case of emergency, the control panel is fitted with a Unit Switch to stop the unit in an emergency. When operated, it removes the low voltage 120VAC electri-cal supply from the unit controller, thus shutting down the unit.

SECTION 2 – PRODUCT DESCRIPTION
INTRODUCTION
YORK YLAA Air-Cooled Scroll Chillers provide chilled water for all air conditioning applications us-ing central station air handling or terminal units. They are completely self-contained and are designed for out-door (roof or ground level) installation. Each complete packaged unit includes hermetic scroll compressors, a liquid cooler, air cooled condenser, a charge of Zero Ozone Depletion Potential Refrigerant R-410A and a weather resistant microprocessor control center, all mounted on a rugged steel base.
The units are completely assembled with all intercon-necting refrigerant piping and internal wiring, ready for field installation.
Prior to delivery, the packaged unit is pressure-tested, evacuated, and fully charged with Refrigerant R-410A and oil. After assembly, a complete operational test is performed with water flowing through the cooler to as-sure that the refrigeration circuit operates correctly.
The unit structure is heavy-gauge, galvanized steel.
This galvanized steel is coated with baked-on powder paint, which, when subjected to ASTM B117 1000 hour, salt spray testing, yields a minimum ASTM 1654 rating of “6”. Units are designed in accordance with NFPA 70 (National Electric Code), ASHRAE/ANSI 15 Safety code for mechanical refrigeration, ASME, and rated in accordance with ARI Standard 550/590.
GENERAL SYSTEM DESCRIPTION
Compressors The chiller has suction-gas cooled, hermetic, scroll compressors. The YLAA compressors incorporate a compliant scroll design in both the axial and radial direction. All rotating parts are statically and dynami-cally balanced. A large internal volume and oil res-ervoir provides greater liquid tolerance. Compressor crankcase heaters are also included for extra protection against liquid migration.
Brazed Plate Evaporator The compact, high efficiency Brazed Plate Heat Ex-changer (BPHE) is constructed with 316L stainless steel corrugated channel plates with a filler material between each plate. It offers excellent heat transfer performance with a compact size and low weight, re-ducing structural steel requirements on the job site.
The heat exchanger is manufactured in a precisely con-trolled vacuum-brazing process that allows the filler material to form a brazed joint at every contact point between the plates, creating complex channels. The ar-rangement is similar to older plate and frame technol-ogy, but without gaskets and frame parts.
Water inlet and outlet connections are grooved for compatibility with field supplied ANSI/AWWA C-606 couplings.
JOHNSON CONTROLS16
ISSUE DATE: 12/29/2017SECTION 2 – PRODUCT DESCRIPTION
The evaporator is equipped with a thermostat-con-trolled heater. The heater provides freeze protection for the evaporator down to -20°F (-29°C) ambient. The evaporator is covered with 3/4” flexible, closed-cell, foam insulation (K=0.25).
A 1/16” (1.6mm) mesh wye-strainer is provided as standard for installation upstream of the heat exchang-er to prevent clogging from water system debris.
Canadian Registration Number (CRN) Application & Proof of Conformance Since all YLAA brazed plate evaporators are catego-rized as pressure “H” fittings per CSA-B51, a CRN label or marking is not provided on the evaporator. Ac-cording to the Canadian Standards Association’s Boil-er, Pressure Vessel, and Pressure Piping Code B-51 (2009 version), a product registered as a category “H” fitting does not require a label or marking displaying the CRN.

Hot Gas By-Pass Permits continuous, stable operation at capacities below the minimum step of compressor unloading to as low as 5% capacity (depending on both the unit and operat-ing conditions) by introducing an artificial load on the cooler. Hot gas by-pass is installed on only refrigerant system #1 on two-circuited units. (Factory-Mounted)
Flanges (ANSI/AWWA C-606 couplings Type) Consists of (2) Flange adapter for grooved end pipe (stan-dard 150 psi [10.5 bar] cooler). (Not available on optional DX cooler 300 PSIG DWP waterside.) (Field-mounted)
Flow Switch A thermal dispersion type flow switch provides ac-curate, low maintenance flow proving and is included standard. It is factory wired and installed in the exten-sion pipe between evaporator outlet and edge of chill-
er. The extension pipe is secured to the chiller frame for shipping to avoid risk of damage to evaporator

and is easily attached to the evaporator at startup us-ing the supplied ANSI/AWWA C-606 connector. The flow switch can be deleted if alternate or existing flow switch is field supplied.
Heat Recovery Condenser A partially condensing refrigerant to liquid condenser recovers heat off both refrigerant circuits and rejects into a single liquid circuit. Factory installed between the compressor discharge and the condenser (air) coils to capture the maximum amount of heat. Capable of recovering up to 85% total heat of rejection (cooling load plus work input); temperatures as high as 140°F (60°C) are possible.
Hydro-Kit Factory installed Hydro-Kit suitable for water and gly-col systems with up to 35% glycol at leaving tempera-tures down to 20°F. The hydro-kit option is available in a single or dual configuration (dual as standby duty only), with totally enclosed permanently lubricated pump motors.
The hydro-kit option comes standard with a balancing valve, discharge check valve, discharge shutoff valve, thermal dispersion flow switch, pressure ports, inlet wye-strainer, bleed and drain valves and frost protection.
Service shut off valves, additional pressure ports and ex-pansion tanks are optional within the hydro-kit option.
Condenser and Cabinet Options MCHX Condenser protection against corrosive envi-ronments is available by choosing any of the following options. For additional application recommendations, See FORM 150.12-ES1. (Factory-Mounted)
Post-Coated Dipped MCHX Condenser The unit MCHX is constructed with post dipped-epoxy MCHX condenser. This is recommended for seashore and other corrosive applications (with the exception of strong alkalies, oxidizers and wet bromine, chlorine and fluorine in concentrations greater than 100 ppm).
Enclosure Panels (Unit) Tamper proof Enclosure Panels prevent unauthorized access to units. Enclosure Panels can provide an aes-thetically pleasing alternative to expensive fencing.
Additionally, for proper head pressure control, Johnson Controls recommends the use of Condenser Louvered Panels for winter applications where wind gusts may exceed five miles per hour. The following types of en-closure panels are available:
• Wire Panels (Full Unit) - Consists of welded wire-mesh guards mounted on the exterior of the unit. Prevents unauthorized access, yet provides free air flow. (Factory-Mounted)
• Wire/Louvered Panels - Consists of welded wire-mesh panels on the bottom part of unit and louvered panels on the condenser section of the unit. (Factory-Mounted)
• Louvered Panels (MCHX Condenser Only)
- Louvered Panels are mounted on the sides and ends of the MCHX condenser for protection.
(Factory-Mounted)
• Louvered Panels (Full Unit) - Louvered panels surround the front, back, and sides of the unit.
They prevent unauthorized access and visually screen unit components. Unrestricted air flow is permitted through generously sized louvered openings. This option is applicable for any out-door design ambient temperature up to 115°F (46°). (Factory-Mounted)
MCHX End Hail Guard Louvered panel attached to exposed MCHX end. (Fac-tory-Mounted)
Sound Attenuation One or both of the following sound attenuation options are recommended for residential or other similar sound sensitive locations:
• Compressor Acoustic Sound Blanket - Each compressor is individually enclosed by an acous-tic sound blanket. The sound blankets are made with one layer of acoustical absorbent textile fi-ber of 5/8” (15mm) thickness; one layer of anti-vibrating heavy material thickness of 1/8” (3mm).
Both are closed by two sheets of welded PVC, reinforced for temperature and UV resistance.
(Factory-Mounted)
• Ultra Quiet Fans - Lower RPM, 8-pole fan mo-tors are used with steeper-pitch fans. (Factory- Mounted)
Vibration Isolators Level adjusting, spring type 1” (25.4mm) or seismic deflection or neoprene pad isolators for mounting un-der unit base rails. (Field-mounted)

Low pressure liquid refrigerant enters the cooler and is evaporated and superheated by the heat energy ab-sorbed from the chilled liquid passing through the cooler shell. Low pressure vapor enters at the compres-sor where pressure and superheat are increased. The high pressure vapor is fed to the air cooled condenser coil and fans where the heat is removed. The fully con-densed and subcooled liquid passes through the expan-sion valve where pressure is reduced and further cool-ing takes place before entering to the cooler.

SECTION 3 – HANDLING AND STORAGE
DELIVERY AND STORAGE
To ensure consistent quality and maximum reliability, all units are tested and inspected before leaving the fac-tory. Units are shipped completely assembled and con-taining refrigerant under pressure. Units are shipped without export crating unless crating has been speci-fied on the Sales Order.
If the unit is to be put into storage, prior to installation, the following precautions should be observed:
• The chiller must be “blocked” so that the base is not permitted to sag or bow.
• Ensure that all openings, such as water connec-tions, are securely capped.
• Do not store where exposed to ambient air tem-peratures exceeding 112 °F (44.5 °C).
• The condensers should be covered to protect the fins from potential damage and corrosion, particu-larly 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-cidental physical damage.
• 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-spected during storage.
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 damage is evident, it should be noted on the carrier’s freight bill and a claim entered in accordance with the instructions given on the advice note.
Major damage must be reported immediately to your local Johnson Controls representative.
MOVING THE CHILLER
Prior to moving the unit, ensure that the installation site is suitable for installing the unit and is easily ca-pable of supporting the weight of the unit and all as-sociated services.
The unit must only be lifted by the base frame at the points provided. Never move the unit on rollers, or lift the unit using a forklift truck.
Care should be taken to avoid damaging the condenser cooling fins when moving the unit.
