2 Date: Supersedes: 50FNX,FNY078,088,104 SINGLE-PACKAGE COOLING UNITS, WITH PRODUCT INTEGRATED CONTROLS 50FNX, FNY JOB NAME: LOCATION: BUYER: BUYER P.O. # CARRIER # UNIT NUMBER: MODEL NUMBER: PERFORMANCE DATA CERTIFIED BY: DATE: Rev: DESCRIPTION 50FNX, FNY units are completely packaged, prewired and precharged cooling only units with PRODUCT INTE- GRATED CONTROLS. Units include integral economizer and high-capacity modulating power exhaust. 50FNX, FNY units are built for bottom supply and return applications. Their waterproof construction makes them ideally suited for installation on the accessory roof curb. Units include a discharge plenum at supply fan outlet for sound attenuation. Units are either CONSTANT VOLUME or VARIABLE AIR VOLUME depending on the factory-installed options selected. Unit is factory assembled, rated in accordance with ARI Standard 340/360, tested in accordance with UL Standard 1995, and listed by ETL and ETL, Canada. PRODUCT INTEGRATED CONTROL FEATURES STANDARD CONTROL FUNCTIONS Unit compatible with CARRIER COMFORT NETWORK or stand alone operation. Constant Volume or Variable Air Volume control. Six to 11 steps of capacity staging possible. Supply fan control based on occupancy schedule using 365-day electronic timeclock with holiday scheduling. Time schedule override through the space temperature sensor provided with the unit. Compatible with 37H and 45 Series PIC terminals to form a Digital Air Volume system (DAV). Building pressurization control in conjunction with modulating power exhaust. Supply duct static pressure controlled through factory-installed inletguide vanes or field or factory supplied inverter. Head pressure control to 20 F. Head pressure controlled by saturatedcondensing temperature. Low ambient control utilizes Motormaster II fan cycling. Lead-lag refrigeration system control to even out circuit run time. Self-diagnostic run test confirms control and component operation at unit commissioning. Self-diagnostic troubleshooting codes indicate the reason unit tripped to expedite unit repair. Codes expand to English Text. Building Purge Mode flushes building interior with outdoor air to remove contaminants before occupancy. Adaptive Optimal Start minimizes the amount of time and energy required before entering the occupied mode. Unoccupied Mode Free Cooling units will utilize free cooling whenever possible to maintain the unoccupied set point. Input/Output of data and monitoring of alarms can be done remotely using Building Supervisor, or at the unit using the accessory HSIO module. Delayed Mechanical Cooling units will utilize cooling to cool the space 3 degrees below the occupied set point to delay the need for mechanical cooling. ADDITIONAL CONTROL FUNCTIONS Provides a discrete output with occupancy control for use as specified by the customer. Controls a field installed humidifier using a 4 to 20 ma or 2-stage output. Requires accessory humidity sensor. Smoke Control functions (Pressurization, Evacuation, Smoke Purge, and Fire Shutdown) are provided through software. Terminals are provided to interface with field supplied smoke/fire panel. Provides a 4 to 20 ma output to proportional hot water control valve for field supplied hydronic heating coil (located externally from the unit). Requires a field supplied freezestat to protect coil. Differential enthalpy control can be provided using field installed accessory return air enthalpy sensors. Economizer control field configurable to: Maintain a minimum economizer set point position, OR Maintain the minimum economizer position based on input from an IAQ sensor (field supplied 0 to 10 volt), OR Maintain a constant CFM of outdoor air intake (requires accessory Outdoor Air CFM package), OR Look at all three above and maintain minimum economizer position based on the dominant parameter. 2

3 Standard one-year warranty. Standard unit as factory-assembled is listed by ETL and ETL, Canada. Units are rated in accordance with ARI Standard 340/360. Integrated economizer system including solid-state enthalpy controls, spring return actuator, low-leak damper section, and bottom-entry outdoor air hoods with serviceable permanent washable aluminum mesh filters. High-capacity modulating power exhaust system controlling to space pressure, with Variable Frequency Drive and factory-installed outlet hoods with backdraft dampers. Semi-hermetic Carrier Carlyle compressors. Dual refrigeration circuits, pre-charged with R-22. Intertwined evaporator coils with TXVs. Crankcase heaters. Compressor protection includes high- and low-pressure cutouts. UNIT FEATURES Cabinet made of prepainted galvanized steel, weathertight construction with 500-hr salt spray finish. Tuf-Skin Rx anti-microbial insulation. Large hinged access doors. Lifting lugs for overhead rigging. Sloped condensate pan. Two-inch pleated return air filters (30%). Single low-rpm supply fan with 2-in. deflection isolation springs under fan sled and fixed-speed fan drives matched to motor horsepower. High efficiency supply and exhaust fan motors (meet EPACT requirements). Circuit breaker protection for all power components, including compressors, supply fan motor, exhaust fan motors and control circuits. Condenser-fan motors are internally protected 3-phase motors. 115-volt and 24-volt control circuit. Single-point electric service entry.
