INTRODUCTION
Most any air conditioner will keep you cool. Our air conditioner was designed to do
it effi ciently. Effi ciency means less cost to you while keeping you comfortable.
WHY YOUR AIR CONDITIONER WORKS SO WELL, SO QUIETLY
1.
Air is cooled by a large evaporator coil. Moisture is also removed from the air by
this same coil.
2.
Air is then delivered through the main duct, via registers, into your home.
3.
Return air is drawn through the return register.
4.
This air enters the unit, passes through the evaporator coil, is cooled and dehumidi-
fi ed. Then the cycle begins again.
