Evaporator Coil Cleaning
The following cleaning procedure is recommended as part of routine maintenance activity for all American Panel
Corporation blast chillers.
IMPORTANT: Do not use any sharp or abrasive tools to clean the evaporator coil!
Before cleaning the evaporator coil run the defrost cycle to make sure the coil is completely free of ice.
When cleaning the evaporator coil particular attention must be paid to the kind of cleansing agent used. The following
products MUST NEVER BE USED:
• Ammonia or detergents which contain ammonia (ammoniac solutions)
• Bleach or products containing bleach (chlorinated liquids)
• Acid detergents such as anti-lime scale, various anti-incrustations, muriatic acid, sulfuric, hydrochloric and acetic
acid liquids, etc. (highly acidic liquids)
• Acetone, trichloro-ethylene (organic solvents)
• Caustic soda and other highly alkaline substances (high basicity liquids)
All the above substances can damage the protective coating and/or corrode the metal components and seriously
damage the coil.
WARNING: Disconnect and lock the main power switch prior to cleaning the unit.
Monthly
• Open the evaporator door by removing the screws that secure the door to the vertical frame and swing

• Use a vacuum cleaner or a soft non-metallic bristle to remove the surface loaded fibers and dirt. Apply the tool in
the direction of the fins.
• Rinse the coil finned area and the return bends with plenty of clean warm water. To avoid damaging the fins and
the coating, it is important that the water temperature is below 130oF and the water pressure is below 100 PSI.
