Model YLAA Air-Cooled Scroll Compressor Liquid Chillers Style B

FORM 150.62-EG5 (509)tures down to 20°F. The Hydro-kit option is available in asingle or dual configuration (dual as standby duty only), withtotally enclosed permanently lubricated pump motors.The hydro-kit option comes standard with a balancing valve,flow switch, pressure ports, suction guide, strainer, bleedand drain valves and frost protection.Expansion tanks are optional within the Hydro-Kit option.CONDENSER AND CABINET OPTIONS:Condenser coil protection against corrosive environmentsis available by choosing any of the following options. Foradditional application recommendations, refer to FORM150.12-ES1. (Factory-Mounted)PRE-COATED FIN CONDENSER COILS – The unit’scoils are constructed with epoxy coated aluminum fins.This can provide corrosion resistance comparable to copper-fincoils in typical seashore locations. Either these orthe post-coated coils (below), are recommended for unitsbeing installed at the seashore or where salt spray mayhit the unit.POST-COATED DIPPED CONDENSER COILS – Theunit’s coils are constructed with dipped-cured condensercoils. This is another choice for seashore and other corrosiveapplications (with the exception of strong alkalies,oxidizers and wet bromine, chlorine and fluorine in concentrationsgreater than 100 ppm).COPPER FIN CONDENSER COILS – The unit’s coils areconstructed with copper fins. (This is not recommended forunits in areas where they may be exposed to acid rain.)ENCLOSURE PANELS (UNIT) – Tamperproof EnclosurePanels prevent unauthorized access to units. EnclosurePanels can provide an aesthetically pleasing alternativeto expensive fencing. Additionally, for proper head pressurecontrol, Johnson Controls recommends the use ofCondenser Louvered Panels for winter applications wherewind gusts may exceed five miles per hour. The followingtypes of enclosure panels are available:WIRE PANELS (Full Unit) – Consists of weldedwire-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 wiremeshpanels on the bottom part of unit and louveredpanels on the condenser section of the unit. (Factorymounted).LOUVERED PANELS (Condenser Coil Only)– Louvered panels are mounted on the sides and ends ofthe condenser coils for protection. (Factory-Mounted)LOUVERED PANELS (Full Unit) – Louvered panelssurround the front, back, and sides of the unit. Theyprevent unauthorized access and visually screen unitcomponents. Unrestricted air flow is permitted throughgenerously sized louvered openings. This option is applicablefor any outdoor design ambient temperature upto 115°F (46°C). (Factory-Mounted)COIL END HAIL GUARD – Louvered panel attached toexposed coil end. (Factory-Mounted)sound attenuation – One or both of the followingsound attenuation options are recommended for residentialor other similar sound sensitive locations:COMPRESSOR ACOUSTIC SOUND BLANKET – Eachcompressor is individually enclosed by an acoustic soundblanket. The sound blankets are made with one layer ofacoustical absorbent textile fiber 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 motorsare used with steeper-pitch fans. (Factory-Mounted)VIBRATION ISOLATORS – Level adjusting, spring type 1"(25.4mm) or seismic deflection or neoprene pad isolatorsfor mounting under unit base rails. (Field-mounted)jOHNSON CONTROLS
