Features/Benefits
One-piece heating and cooling units with low sound levels, easy installation, low maintenance, and dependable performance. 
Puron Advance is Carrier's latest choice of Refrigerant to help meet the 2025 GWP requirement. This unit is designed and tested with Puron Advance and contains a dissipation system.

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. 

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 in the vertical airflow mode.

Efficient operation High-efficiency design offers SEER2 (Seasonal Energy Efficiency Ratios) of 13.4, 11.05 EER2, and AFUE (Annual Fuel Utilization Efficiency) ratings of 81.0%. 

Energy-saving, direct spark ignition saves gas by operating only when the room thermostat calls for heating. Standard units are furnished with natural gas controls. A low-cost field installed kit for propane conversion is available for all units. 

Low NOx units meet 40 ng/J NOx emissions. Can be installed in air quality management districts with a 40 ng/J NOx emissions requirement. 

Durable, dependable components 
Monoport inshot burners produce precise air-to-gas mixture, which provides for clean and efficient combustion. The large monoport on the inshot (or injection type) burners seldom, if ever, requires cleaning. All gas furnace components are accessible in one compartment.  

Turbo-tubular™ heat exchangers are constructed of stainless 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 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 low ambient 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 non-ozone depleting and low global warming potential Puron Advance (R-454B) refrigerant charge. Refrigerant service connections make checking operating pressures easier. Factory-installed leak detection dissipation system for added safety.

High Pressure Switch provides added reliability for the compressor.

Indoor and Outdoor coils are computer-designed for optimum heat transfer and efficiency. The indoor coil is fabricated from aluminum tube and aluminum fins and is located inside the unit for protection against damage. The outdoor coil is internally mounted on the top tier of the unit. 

Low sound ratings ensure a quiet indoor and outdoor environment with sound ratings as low as 69.0 dBA. 

Easy to service cabinets provide easy 3-panel accessibility to serviceable components during maintenance and installation. The basepan with integrated drain pan provides easy ground level installation with mounting pad. 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. 

Standard horizontal metal duct covers with insulation come with the unit \and cover the horizontal duct openings. These can be left in place if the units are converted to downflow. 

Integrated Gas Control (IGC) board provides safe and efficient control of heating and simplifies trouble-shooting through its built-in diagnostic function. 

Cabinets are constructed of heavyduty, phosphated, zinc-coated prepainted steel capable of withstanding 500 hours in salt spray. Interior surfaces of the evaporator/heat exchanger compartment 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 62.2.) The sloped drain pan minimizes standing water in the drain. An external drain is provided.

Impressive sources, sophomoric writing.
Format: Kindle
Should everyone read this book? Certainly. But the writing is too poor for me to offer an enthusiastic four or five star recommendation. I'm surprised an editor did not clean this up so that the book could live up to its eye-opening content. This already short book has quite a lot of distracting, repetitive padding. Symbolic of this is the use of the phrase "of course" - it appears thirty times. More repetition appears in the author's needless (and, I would say, presumptuous) dwelling on the reader's emotional reactions to the content of the book: the idea that America might have influenced the Nazis is "too awful to contemplate," and "is sure to seem distressing," and "hard to digest," and "no one wants to imagine" it, and "none of this is entirely easy to talk about," and "it is hard to look coolly on the question," and "it is hard to admit," and "no one wants to be perceived as relativizing," and "no non-Germans want their country to be accused," and "it is hard to overcome our sense that..." and "painful though it may be for us to admit..." and "awful it may be to contemplate," and "the story of American influence...is certainly depressing," and so on and so forth. Nevertheless, "To be sure, we must keep our composure..." This repetition gets exhausting in a single 56-word sentence invoking the phrases "true nefandum...abyss of unexampled modern horror...sui generis radical evil...a sort of dark star." More padding appears in the author's concern with arguing against weak positions: "We can, and should, reject the sort of simple-minded anti-Americanism..." "It would be a mistake to draw overblown conclusions..." Well, yes, simple-minded anything is to be rejected, as are overblown conclusions about anything. But that doesn't stop the author from presenting repetitive arguments. Additional filler that an editor should have excised is in the form of these phrases, which read like a student trying to hit a required word count in a term paper: "It is important to note that..." "In particular it is essential to emphasize..." "We must bear that fact in mind..." "It is an unpleasant truth that..." "Worthy of attention above all is..." "It is particularly noteworthy that..." "Sahm is a particularly noteworthy author..." Finally, the author descends into a kind of bullying that indicates a lack of confidence in his own presentation: "Our literature has taken a crass interpretative track." "It is a major interpretative fallacy on the part of all these scholars..."It would be foolish and craven to minimize Nazi interest in what American law represented." "It is essential to reject once and for all the proposition that American law could not have been of interest to the Nazis." "It is simply nonsense to claim..." "Once we dispose of that dubious claim..." "There can be no justification for ignoring the evidence..." "Only a naive and pedestrian understanding of law - only a dogged refusal to face facts..." An editor should have deleted these kinds of phrases and just let the content - the documenting of Nazi interest in America law - speak for itself. With all this rhetorical padding, the book is overpriced. Nevertheless it has value as a kind of annotated bibliography.

Thoughtful, well researched, not a "fun" read
Format: Hardcover
This was a very thoughtful look at a topic I didn't know much about. It talks about prewar anti race mixing laws and immigration laws in the USA and other laws used to strip rights from nonwhites in the USA and how those laws were studied by Nazis who wrote laws for the third reich and what they thought of each other. The author obviously put a lot of research and thought into this work but is careful not to jump to any conclusions. This book is very dense and as someone who is not a lawyer or anything, I could follow it but I had to read it more slowly than most other nonfiction books. Still very worth picking up if you are interested in the topic, though!

Format: Kindle
I must say, I am EXTREMELY biased towards Tim Wise. I adore him. He is a well-educated, genuine wordsmith. He shuts down the mess that we hear perpetrated on a daily basis regarding colorblind politics. In this book, he shuts down "colorblindness". I really love the fact that he criticized President Obama for his lack of legislation specifically for African-Americans. That was an issue I had with him and I believe that several African-Americans feel the same way. I understand, like Tim Wise, the position of President Obama and how easy it would have been for him to fall into a stereotype. I also believe that, no matter what he did, he will always be stereotyped, so why not help out the people who got you elected? Great book by a "Wise" man.

Insights on the new racism
Format: Paperback
Wise, with good insight and armed with up-to-date facts, compellingly portrays the new strategies that have been developed within the US political system that actually serve to perpetuate racism in our society. Scary and brutal--a must read for anyone who really wants to know how our society subtley and not so subtley pushes a White supremacy agenda without even knowing it.
