The cooler is equipped with a heater controlled by a separate thermostat. Water inlet and outlet connections are grooved for compatibility with factory supplied ANSI/AWWA C-606 connections. Installing contractor must include accommodations in the chilled water piping to allow proper drainage and venting of the heat exchanger. COOLER Brazed plate heat exchangers are UL (Underwriters Laboratories) listed. Compressor crankcase heaters are also included for extra protection against liquid migration. A large internal volume and oil reservoir provides greater liquid tolerance. All rotating parts are statically and dynamically balanced. The compressors incorporate a scroll design that is compliant in both the axial and radial direction. COMPRESSORS The chiller has suction-gas cooled, hermetic, scroll compressors.

Units are designed in accordance with NFPA 70 (National Electric Code), ASHRAE/ANSI 15 Safety code for mechanical refrigeration, ASME, Listed and labeled with Intertek Testing Services (ETL) and rated in accordance with the latest version of ARI Standard 550/590. Unit also includes service isolation valves as standard.
Corrosion resistant wire mesh panels are added to protect the condenser coil from incidental damage and restrict unauthorized access to internal components. The steel is coated with baked-on powder paint, which, when subjected to ASTM B hour, salt spray testing, yields a minimum ASTM 1654 rating of 6. The unit structure is heavy-gauge, galvanized steel. After assembly, a complete operational test is performed with water flowing through the cooler to assure that the refrigeration circuit operates correctly. The unit is pressure-tested, evacuated, and fully charged with R-410A and includes an initial oil charge. GENERAL The Ton ( kw) YCAL models are shipped complete from the factory ready for installation and use. Each unit includes hermetic scroll compressors, a liquid cooler, air cooled condenser, a charge of refrigerant R-410A, and a weather resistant microprocessor control center, all mounted on a rugged, formedsteel base. They are completely self-contained and are designed for outdoor (roof or ground level) installation. 4 JOHNSON CONTROLSĥ Introduction FORM EG1 (915) YORK Air-Cooled Scroll Chillers provide chilled water for all air conditioning applications using central station air handling or terminal units. 7 ACCESSORIES AND OPTIONS SELECTION DATA DESIGN PARAMETERS WATER PRESSURE DROP RATINGS PHYSICAL DATA AND NOMINAL RATINGS PART LOAD RATINGS UNIT DIMENSIONS ISOLATOR DETAILS ELECTRICAL DATA - 50 & 60HZ ELECTRICAL NOTES CIRCUIT BREAKER CALCULATIONS POWER WIRING - SINGLE CIRCUIT CONTROL WIRING APPLICATION DATA GUIDE SPECIFICATIONS Performance data provided in this document was created in accordance with Johnson Controls software: YORKworks version and DXCHILL version 6.04 JOHNSON CONTROLS 3Ĥ THIS PAGE INTENTIONALLY LEFT BLANK.
