Features/Benefits

One-piece heating and cooling units with low sound levels, easy
installation, low maintenance, and dependable performance.
Puron is Carrier's unique refrigerant designed to be environmentally
balanced. Puron is an HFC refrigerant which does not contain chlorine
that can harm the ozone layer. The most important advantage of Puron
refrigerant is that it has not been banned in future air conditioning
systems as the traditional refrigerant R-22 has been. Puron refrigerant is
in service in millions of systems proving highly reliable and is
non-ozone depleting.
Easy Installation
Factory-assembled package is a compact, fully self-contained,
combination gas heating/electric cooling unit that is prewired, pre-piped,
and pre-charged for minimum installation expense. These units are
available in a variety of standard and optional heating/ cooling size
combinations 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.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
Product Data
Innovative Unit Base Design
On the inside a high-tech composite material will not rust and
incorporates a sloped drain pan which improves drainage and helps
inhibit mold, algae and bacterial growth. On the outside metal base rails
provide added stability as well as easier handling and rigging.
Convertible Duct Configuration
Unit is designed for use in either downflow or horizontal applications.
Each unit is converted from horizontal to downflow and includes two
horizontal duct covers. Downflow operation is provided in the field to
allow vertical ductwork connections. The basepan seals on the bottom
openings to ensure a positive seal cin the vertical airflow mode.
Efficient operation high-efficiency design offers SEER (Seasonal
Energy Efficiency Ratios) of 14.0, 11.5 EER, and AFUE (Annual Fuel
Utilization Efficiency) ratings up to 81.0%.
Energy-saving, direct spark ignition saves gas by operating only when
the room thermostat calls for heating. Standard units are furnished with
A170030
natural gas controls. A low-cost field installed kit for propane
conversion is available for all units.
Ultra Low NOx units meet South Coast Air Quality Management
District (SCAQMD) and San Joaquin Air Pollution Control District
(SJAPCD) are regulating a reduction of 65%, down to no more than
14ng/J of NOx emissions.
Durable, Dependable Components
Turbo-tubular™ heat exchangers are constructed of stainless steel
and aluminized steel for corrosion resistance and optimum heat transfer
for improved efficiency. The tubular design permits hot gases to make
multiple passes across the path of the supply air.
In addition, dimples located on the heat exchanger walls force the hot
gases to stay in close contact with the walls, improving heat transfer.
ECM Blower Motor is standard on all models.
Direct-drive PSC (Permanent Split Capacitor) condenser-fan
motors are designed to help reduce energy consumption and provide for
cooing operation down to 40°F (4.4°C) outdoor temperature.
Motormaster® II lowambient kit is available as a field-installed
accessory.
Thermostat Controls
Time Guard® 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.
High pressure switch provides added reliability for the compressor.
Low pressure switch (24 and 30 size only) provides added reliability
for the compressor.
