819448-UUM-A-1011 HOW YOUR SYSTEM WORKS COOLING CYCLE If your hand is wet and you blow on it, it feels cool because some of the moisture is evaporating and becoming a vapor. This process requires heat. The heat is being taken from your hand, so your hand feels cool. That’s what happens with an air conditioner. During the cooling cycle, your system will remove heat and humidity from the space and will transfer this heat to the outdoor air.

819448-UUM-A-1011 FAN OPERATION SELECTION A multi-position fan switch allows you to choose the type of fan operation of the indoor fan. AUTO With the thermostat fan switch set to “AUTO”, the fan will run intermittently as required for either heating or cooling. This position will provide the lowest operating cost.

819448-UUM-A-1011 TO MAXIMIZE OPERATING EFFICIENCY HEATING CONSERVATION For the most efficient operation, keep storm windows and doors closed all year long. They not only help insulate against heat and cold, but they also keep out dirt, pollen, and noise. Closing drapes at night, keeping fireplace dampers closed when not in use, and running exhaust fans only when necessary will help you to retain the air you have already paid to heat.
PAGE 5
SOME EFFICIENCY DO’S & DON’TS DON’T heat or cool unused household areas. Reduce supply and return air flow to a minimum in areas which are not living/ working spaces (storage rooms, garages, basements, etc). DON’T be a “thermostat jiggler”. Moving your thermostat setting will not make your system heat or cool any faster. Adjust your thermostat to a comfortable setting and leave it there. DON’T restrict air circulation. Placing furniture, rugs, etc.
