Horizontal units are designed for suspended ceiling mounting. Horizontal models are shipped with ‘straight-through’ evaporator fan discharge as standard. Fan orientation is field convertible to side discharge. Vertical units are designed for free-standing floor mounting. All units are completely factory wired and pre-piped. Water supply, water outlet, and condensate drain connections are via female pipe thread fittings. CABINET All cabinets are completely constructed of 18 Ga. corrosion resistant “Galvalume” coated steel. The horizontal units are complete with integral hanger channels. The entire unit interior (both evaporator and condensing section) is insulated with 1/2” thick, 2 lb. density insulation. Service panels are equipped with lifting handles for ease of removal and handling. All units provide excellent service access to the reversing valve, thermal expansion valve, and compressor with the unit remaining in location. An integral duct collar is provided on the blower discharge opening. An optional discharge plenum is available for Vertical models. REFRIGERANT CIRCUITS All models utilize hermetic rotary or reciprocating type compressors. Compressors are mounted on rubber isolators to minimize vibration transmission. Internal overload protection is provided. External high pressure and low pressure cutout switches are included in each compressor control circuit. Each refrigeration circuit includes an adjustable biflow thermal expansion valve (with external equalizer), bi-flow liquid line filter drier, and service gauge ports. The reversing valve is a pilot operated, sliding piston type with a replaceable magnetic solenoid coil. The refrigerant-to-air heat transfer coils are constructed of internally enhanced copper tubes mechanically bonded to enhanced aluminum plate fins. The evaporator coil is employed in a draw-through configuration. Large evaporator coil face area minimizes potential water blow-off. The coaxial refrigerant-to-water heat exchangers feature a convoluted inner tube design for high heat transfer efficiency. Standard models feature a copper inner tube surrounded by a steel outer tube, and carry a 400 psig water side working pressure rating. 359583-YTG-B-0208 ELECTRICAL/CONTROLS All units are completely factory wired with all necessary operating controls. A 24 volt control circuit, with oversize transformer, is provided for field connection. Units are designed to operate with conventional thermostat control interface. The reversing valve solenoid coil shall be energized in cooling mode only. A manual reset is provided on each compressor control circuit in the event of high/low pressure cutout. A time delay relay for anti-short cycle protection is standard in all units. An optional condensate overflow switch is avail- able, complete with an alarm output contact. An optional remote management package allows the unit to be controlled by an external source. FILTERS All models are shipped with 1 inch thick throw-away filters factory installed. Filters are accessible from either side of unit.
