1. Chemicals to aid in cleaning WILL VOID WARRANTY and are NOT RECOMMENDED.
2. In some instances, it may take a combination of two methods to result in a clean coil.
Such as, first wiping the coil to clean the surface and then using a vacuum, water or
compressed air to clean down in the fins. This will depend on the type of debris that
needs to be cleaned from the coil.
3. Do not contact the coil with any hard vacuum nozzle, air nozzle, or any other tool. This
will damage the tubes of the coil.
4. The use of cleaning agents or detergents is strongly discouraged due to the possibility
of degradation of the construction. If using a power washer, the nozzle pressure
should not exceed 600 psi (41 bar). For the best results, spray the coil perpendicular to
the face of the coil. The spray nozzle should be kept between 1 inch and 3 inches (25 to
75 millimetres) from the coil surface.
5. If necessary to use a chemical cleaner or detergent use a cleaner that does not contain
any hydrofluoric acids and is between 7 and 8 on the pH scale. Ensure dilution
instructions provided by the detergent supplier are followed. In case of doubt about
the compatibility of the detergent with the type of materials listed above, always ask
the supplier a written confirmation of the compatibility. Should a chemical cleaner be
required, it is MANDATORY that all components are thoroughly rinsed with water
even if the instructions of the cleaner specify that it is a “no rinse” cleaner.

6. The repeated transportation of meat and fish waste can cause extensive corrosion to
the evaporator coils and evaporator section tubing over time due to ammonia
formation and can reduce the lifespan of the coils. Appropriate additional measures
should be taken to protect the coils against the aggressive corrosion that can result
from transportation of such products.
