Condenser Coils — Cleaning and
Inspection
Coil Cleaning and Inspection Interval
Clean condenser coils at least once a year or more
frequently if it is in a “dirty” environment. A clean
condenser coil will help maintain chiller operating
efficiency. Perform coil inspection each time coils are
cleaned.
Cleaning Air Side of RTAE Coils
Do not use detergents to clean the air side of RTAE coils.
Use clean water only. Clean from inside out by removing
end panels.
Cleaning Coated Coils
Coated coils may be cleaned using traditional detergents.
Coil Corrosion Protection Inspection
Inspect corrosion protection at each coil refrigerant
connection where the copper tube joins the aluminum
manifold. If damaged or missing, wrap new Prestite
Insulation (STR01506) on joint to cover area from the
aluminum header body to at least 2 inches of the copper
tube. Seal insulation using hand pressure. Rubber gloves
are suggested when handling insulation.
