NNoottee:: Listed in order of recommended method.
Take a cloth or towel and wipe the air side of the coil going with the fins, across the tubes. The coil will clean in a
manner similar to the way lint cleans from the lint trap of a household clothes dryer.
Use a soft bristled brush (DO NOT USE A WIRE BRUSH) and brush the coil going with the fins, across the tubes. The
coil will clean in a manner similar to the way lint cleans from the lint trap of a household clothes dryer.
A vacuum with a soft attachment can be used to suck the debris off the face as well as in the fins and tubes from the
air side of the coil.
Compressed air can be used and will work best when blown thru the coil from the non-air side when possible.
Blowing thru from the airside may imbed debris in the coil that was only on the surface. It is recommended to start
with one of the first three options before using compressed air if the non-air side is not accessible. The angle at
which the air should be directed at the coil should not be less than 75 degrees.
