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.

My dogs love this
My dogs love this stinking toy. I’m about to buy another one though bc they are tearing it up. But overall they are pretty rough with it and suckle on it. I didn’t think this would be such a hit for them but I’m ok with repurchasing it for the amount of love they have for this!

Almost worked!
I have an EXTREMELY destructive Boston Terrier. She loves playing with her toys, but she loves destroying them even more. "Chicken" was her Christmas present and she loved him. She did pull his eyes off right away, fortunately she didn't swallow them, but I was excited that she couldn't immediately shred him. Then she found his weak spot. She managed to grab hold of the tag and tore the seam, and now she just plays with Chicken's torn up husk. He lasted 3 days, which was longer than any other stuffed animal. I would purchase again, but I would cut the tag as short as I could before giving it to her. It was a good run, but I'm still looking for a soft you she can't destroy!

My 18 lb dog had this torn apart in MINUTES
You are going to read this review and think "my dog will be different" just as I did reading some of the poor reviews. I was bamboozled by this product thinking that there must be something special about it and I was poorly mistaken. First off my dog did love this toy right out of the box. Secondly she had it destroyed in mere MINUTES! I was truly stunned. If you feel you must still purchase this stuffed toy after reading my review please find one by this company that is on sale, do NOT pay full price. She had the trim chewed off, a wing off, the squeakers out within 15 min and I am not exaggerating. There was stuffing EVERYWHERE. Was it kind of amusing? Yes. Was I disappointed in the "chew guard" technology? Absolutely. Be warned! If your dog destroys stuffed animals this one will be no different!!

The puppy loves it!
Our new little Rat Terrier, w/ razor sharp teeth and toenails, seems to love this toy. She has learned to squeak the wings and feet, but the belly squeaker is too well buried for her, so when I squeak it, she comes running! After three weeks, it is well chewed, but NO holes in it! Puppies have short attention spans, but she will chase this happily for about 15 minutes, when we're playing Squeak and Throw! Actually, I get tired of throwing it, before she tires of chasing it!
