50XP Performancet 13 SEER Single--- Packaged Air Conditioner System with PuronR (R ---410A) Refrigerant Single and Three Phase 2 to 5 Nominal T ons (Sizes 024--- 060)

Product Data

Easy Installation Factory--assembled package is a fully self--contained, electric

cooling unit that is prewired, pre--piped, and pre--charged for minimum installation expense. These units are available in a variety of standard cooling sizes with voltage options to meet residential and light commercial requirements. Units are lightweight and install easily on a rooftop or at ground level. The high tech composite base eliminates rust problems associated with ground level applications.

Durable, dependable components Scroll Compresso rs are designed for high efficiency. Each

compressor is hermetically sealed against contamination to help promote longer life and dependable operation. Each compressor also has vibration isolation to provide quieter operation. All compressors have internal high pressure and overcurrent protection.

Convertible duct configuration

Unit is designed for easy use in either downflow or horizontal applications. Each unit is easily converted from horizontal to downflow. Downflow operation is easily provided in the field to allow vertical ductwork connections. The basepan utilizes

FEATURES/BENEFITS

One--piece cooling unit with optional electric heater, low installation cost, dependable performance and easy maintenance.

Efficient operation High--efficiency design with a SEER (Seasonal Energy Efficiency

Ratio) of up to 13.5. Puron Environmentally Sound Refrigerant is Carrier’s unique

refrigerant designed to help protect the environment. Puron is an HFC refrigerant which does not contain chlorine that can harm the ozone layer. Puron refrigerant is in service in millions of systems proving highly reliable, environmentally sound performance.

IdealHumidity Technology featuring Thermidistat control and Variable Speed Blower motor that provides greater comfort,

humidity control, and energy efficiency. You can expect up to 30 times better dehumidification; economical constant fan for less than $50 a year, which provides improved indoor air quality and more even temperatures from room to room; and reduced indoor noise due to lower air velocity. In addition, you’ll realize improved installation flexibility with 3 different airflow choices for best overall comfort.

knockout style seals on the bottom openings to ensure a positive seal in the horizontal airflow mode.

Direct--drive variable speed blower motor is standard on all models.

Direct--drive PSC condenser--fan motors are designed to help reduce energy consumption and provide for cooing operation downto55_F(13_C) outdoor temperature. Motormasterr II low ambient kit is available as a field--installed accessory.

Thermostat controls

Time Guardr II anti--short cycle protection circuitry. If a non--corporate thermostat without anti--short cycle protection is used the Time Guard II field--installed anti--short cycle kit is recommended.

Refrigerant system is designed to provide dependability. Liquid filter driers are used to promote clean, unrestricted operation. Each unit leaves the factory with a full refrigerant charge. Refrigerant service connections make checking operating pressures easier.

Thermostatic Expansion Valve -- A hard shutoff, balance port TXV maintains a constant superheat at the evaporator exit (cooling cycle) resulting in higher overall system efficiency.

Evaporator and condenser coils are computer--designed for optimum heat transfer and cooling efficiency. The evaporator coil is fabricated from copper tube and aluminum fins and is located inside the unit for protection again damage. The condenser coil is internally mounted on the top tier of the unit. Copper fin coils and pre--coated fin coils are available from the factory by special order. these coils are recommended in applications where aluminum fins are likely to be damaged due to corrosion. They are ideal for seacoast applications.

High and Low Pressure Switches provide added reliability for the compressor.

Low sound ratings ensure a quiet indoor and outdoor environment with sound ratings as low as 72dBA. (See Page 4.)

Easy to service cabinets provide easy single--panel accessibility to serviceable components during maintenance and installation. The basepan with integrated drain pan provides easy ground level installation with or without a mounting pad. Convenient handholds are provided to manipulate the unit on the jobsite. A nesting feature ensures a positive basepan to roof curb seal when the unit is roof mounted. A convenient 3/4--in. (19.05 mm) wide perimeter flange makes frame mounting on a rooftop easy.

Louvered Grille provides hail and vandalism protection for the coil.

Cabinets are constructed of heavyduty, phosphated, zinc--coated prepainted steel capable of withstanding 500 hours of salt spray. Interior surfaces of the evaporator and electric heater compartments are insulated with cleanable semi--rigid insulation board, which keeps the conditioned air from being affected by the outdoor ambient temperature and provides improved indoor air quality. (Conforms to American Society of Heating, Refrigeration and Air Conditioning Engineers No. 62P.) The sloped drain pan minimizes

to be fitted to 14 in. (355.6 mm) round ductwork. Thermidistat Control coupled with the system’s variable speed

indoor blower delivers Carrier’s patented IdealHumidity Technology that allows for even greater humidity control. Along with more precisely controlling temperature and humidity, the Thermidistat offers full seven--day programmability allowing you to further customize your comfort and energy savings.

Thermostats provide control for the system heating and cooling functions. Thermostat models are available in both programmable and non--programmable versions.

Crankcase Heater provides anti--floodback protection for low--load cooling applications.

Compressor start kit assists compressor start--up by providing additional starting torque on single phase units and prolongs compressor motor life.

Rigging kit includes lifting brackets which are inserted into the unit base rigging holds to lift unit for rooftop applications.

Low--ambient kit (Motormaster II control) allows the use of mechanical cooling down to outdoor temperatures as low as 0_F (--17_C) when properly installed.
