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

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.
