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.
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 Compressors 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
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
down to 55_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.
